To address the challenges posed by differences in biological maturity and the limitations of existing testing methods, particularly in adolescent sports contexts, there is a pressing need for a non-invasive method that is convenient, accurate, and broadly applicable to monitor the biological maturity of adolescent athletes comprehensively. In response to this need, a maturity assessment method based on the smartphone application Maturo has been developed. This study evaluates the accuracy and validity of the Maturo software, an automated tool for estimating biological age and related maturation metrics.Methods: A sample of 103 actively training teenage athletes aged 9-17 years. The sample included 76 males(age = 11.74 ± 1.55 years, mean ±SD) and 27 females(age = 13.95 ± 1.40 years), all without medical conditions that might impact growth or development.Results: Compared to traditional expert evaluations, the intraclass correlation coefficients(ICCs) and Pearson correlation coefficients demonstrated reliable positive correlations and significant agreement between the Maturo software and expert methods across multiple metrics, such as biological age(ICC = 0.965, R = 0.97), corrected biological age(ICC = 0.973, R = 0.99), predicted adult height(ICC = 0.991, R = 0.99), and percentage of adult height achieved(ICC = 0.955, R = 0.97). The Bland-Altman plots provided additional evidence of the validity of the Maturo software estimations, showing low systematic error in most measures. The linear regression analysis produced excellent adjusted R2values: 0.95for biological age and 0.99 for anticipated adult height. The Maturo approach demonstrated a high level of dependability in classifying teenagers into groups based on their maturity status and timing. The κ coefficients of 0.93 for maturity status and 0.82 for maturity timing indicate a nearly perfect agreement with the expert technique.Conclusion: While the Maturo software's non-invasive nature, cost-effectiveness, and ease of use could make it a potential tool for regular monitoring of growth and maturation in young athletes, its promising results in assessing maturation should be interpreted with caution due to limitations such as sample size and demographic constraints. Further longitude research with larger and more diverse populations is needed to validate these preliminary findings and strengthen the evidence for its broader applicability.展开更多

While...Many patients prioritize the ability to return to sports following shoulder replacement surgeries, including total shoulder arthroplasty(TSA), reverse total shoulder arthroplasty(RTSA), and hemiarthroplasty(HA). While activity levels after hip and knee replacements have been well-established in the literature, studies on this topic in the field of shoulder arthroplasty are relatively limited. A review of the literature regarding athletic activity after shoulder arthroplasty was performed using the PubMed database. All studies relevant to shoulder arthroplasty and return to sport were included. The majority of patients returned to their prior level of activity within six months following TSA, RTSA, and shoulder HA.Noncontact, low demand activities are permitted by most surgeons postoperatively and generally have higher return rates than contact sports or high-demand activities. In some series, patients reported an improvement in their ability to participate in sports following the arthroplasty procedure. The rates of return to sports following TSA(75%-100%) are slightly higher than those reported for HA(67%-76%) and RTSA(75%-85%). Patients undergoing TSA, RTSA, and shoulder HA should be counseled that there is a high probability that they will be able to return to their preoperative activity level within six months postoperatively. TSA has been associated with higher rates of return to sports than RTSA and HA,although this may reflect differences in patient population or surgical indication.展开更多

We compared the classical methods of univariate prediction and the Autoregressive Integrated Moving Average （ARIMA） methods. Reliability of the available data was verified with the Time Series Regression with ARIMA Noise, Missing and Outliers （TRAMO） method, and the existence of a trend was verified using Daniel＇s test. For the purposes of this study--the researches collected and analysed secondary data from a 40-year series in 45 sports in Spain covering a very long period of time in a variety of sport disciplines. The study shows that, with the available data, short- and mid-term forecasting is possible in a number of sports, but not in all of them. It also proves that Holt＇s classical method of exponential smoothing is the one that yields best results. Golf, Basketball, Athletics and Hunting NGB show worrying prospects of decline levels and need an immediate change in the strategic plans. Other than for forecasting the evolution of athletes in the mid-term in order to improve strategic planning in NGBs, the present findings can be useful for public authorities to define their aid policies for NGBs, and they can also help companies in the industry to anticipate market developments.展开更多

Sport and tourism are the two disciplines and two different studies but they can be put together so that mutually beneficial. In sports, there are some tourism elements. Conversely through tourism, sports can be nurtured and developed. Another goal is to serve as a tool to introduce and to recognize sport, improve fitness and preparation exercise. In 2006, the Indonesian government began to develop sports industry which is a new field of study in this country. Ministry of Youth and Sports launched a resurgence sports industry in Indonesia. Sport Tourism is very likely developed in Indonesia. Indonesia is a country rich in natural resources which are very beautiful. Indonesia is also rich in diverse cultures. Indonesia is also rich of their human resources. The economic value can be profitable for the state, government and society. Some physics activities in the tourism sports of which are mountaineering, climbing, sport diving, mountain bike, out bond and traditional sport. Conversely, tourism events that can be collaborated with sports activities in Indonesia are Lake Toba festival, Serayu River Festival, Borobudur festival, etc. Finally, if the program is managed well in Indonesia, it will help this country to develop sports tourism sports and encourage people to participate in sports activities. It can also make potential athletes seedlings in various sports. Output of this activity is to encourage public awareness of the sport and responsible for sports performance.展开更多

The average of static pulse rate was 56.4 beats min1. The average heart rate max was 189.7 ± 7.8 beats minl. For the calculation of HRmax （maximal heart rate）, a mathematical figure HRmax = 207 - （0.7 × age） was used. Probands have participated on the same day on a tournament in beach and handball tournament. HR （heart rate） was monitored via Sport Tester Polar. The results were evaluated by Polar software. The data was statistically compiled with the use of arithmetic average and standard deviation. The players played three matches in beach volleyball on one set to 21 points （necessary difference of 2 points）. One set lasted approximate 13.5 min. After a break, they went to play three matches in beach handball. The average HR during beach volleyball was 149.5 ±14.1 beats min-1 and 164.3 ± 14.5 beats min1 in beach handball. In beach volleyball, we also focused on players＇ intensity load differences 172 ±14.1 beats minland goalkeepers 156.5 ± 16.6 beats min1. In the beach volleyball, players spend most of their playing time on the playing area in the zone intensity load 80%-90% HRmax （36% playing time）. In the beach handball, players spend most of their playing time on the playing area in the zone intensity load 90%-100% HRmax （39% playing time）.展开更多

They participated organized sports activities in their universities （including intramural and varsity level）. The participants completed questionnaires measuring the providing and receiving social supports for sports participation and persistency. Providing and Receiving Social Support Scale for Sports Team （Hagiwara and Isogai, 2014） were adopted to investigate the amount of social supports with teammates in a sports team. The results of correlations in providing and receiving social supports demonstrated that the amount of providing social support for teammates related to the amount of receiving social support from teammates in both Japanese and American student＇s athletes. The results of comparison Japan and the U.S. indicated that American student＇s athletes provided more social supports for teammates than Japanese. The present findings might be an important material to better understand Japanese student＇s athletes.展开更多

文摘Background:Sport climbing is becoming incredibly popular both in the general population and among athletes.No consensus exists regarding evidence-based sport-specific performance evaluation;therefore,this systematic review was aimed at analyzing determinants of sport climbing performance and evaluation methods by comparing climbers of different levels.Methods:PubMed,Scopus,and Web of Science were searched up to December 20,2022.Studies providing the self-reported climbing ability associated with different functional outcomes in groups of climbers of contiguous performance levels were eligible.Results:74 studies were finally included.Various methods have been proposed to evaluate determinants of sport climbing performance.Climbing-specific assessments were able to discriminate climbers of different levels when compared to general functional tests.Test validity resulted high for climbing-specific cardiorespiratory endurance as well as muscular-strength,-endurance,and-power;similarly,reliability was good except for cardiorespiratory endurance.Climbing-specific flexibility assessment resulted in high reliability but moderate validity,whereas balance showed low validity.Considerable conflicting evidence was found regarding anthropometric characteristics.Conclusion:The present analysis identified cardiorespiratory endurance as well as muscular-strength,-endurance,and-power as determinants of sport climbing performance.In contrast,balance,flexibility,and anthropometric characteristics seem to count less.This review also proposes an evidence-based Functional Sport Climbing test battery for asses sing performance determinants,which includes tests that have been identified to be valid,reliable,and feasible.While athletes and coaches should rely on evidence-based and standardized evaluation methods,researchers may design specific large-scale trials as a resource for providing additional,homogenous,and comparable data to improve scientific evidence and professionalism in this popular sport discipline.

文摘Background:Accumulating evidence suggests that sports participation promotes the development of inhibitory control,but the influences of the sports category and inhibition type still remain unclear.The categorization of sports based on the open-skill(externally paced)and closed-skill(self-paced)continuum allows for the integration of the environment as a factor contributing to sports-related benefits for inhibitory control.Methods:Cross-sectional data from different studies were combined(n=184)to examine the association between open-and closed-skill sports and cognitive control processes related to interference control and response inhibition.Participants(aged 9-14 years)filled in 7-day physical activity recall protocols and completed a Stroop Color-Word or a Go/NoGo task.The N200,N450,and P300 components of event-related potentials elicited by these tasks were recorded using electroencephalography.Results:Partial correlations supported the belief that time spent in open-skill sports was related to higher performance on inhibition trials.Additionally,path analyses revealed an association between this sports type and a greater negativity in the N200 and N450 amplitudes in both the full sample and group-level analyses.In contrast,no relation was found between sports type and P300 amplitude.Conclusion:The findings suggest that only the engagement in open-skill sports is associated with more effective conflict monitoring and higher performance on tasks demanding inhibitory control.
文摘BACKGROUND Sodium-dependent glucose transporter 2 inhibitors(SGLT2i)have shown efficacy in reducing heart failure(HF)burden in a very heterogeneous groups of patients,raising doubts about some contemporary assumptions of their mechanism of action.We previously published a prospective observational study that evaluated mechanisms of action of SGLT2i in patients with type 2 diabetes who were in HF stages A and B on dual hypoglycemic therapy.Two groups of patients were included in the study:the ones receiving SGLT2i as an add-on agent to metformin and the others on dipeptidyl peptidase-4 inhibitors as an add-on to metformin due to suboptimal glycemic control.AIM To evaluate the outcomes regarding natriuretic peptide,oxidative stress,inflammation,blood pressure,heart rate,cardiac function,and body weight.METHODS The study outcomes were examined by dividing each treatment arm into two subgroups according to baseline parameters of global longitudinal strain(GLS),N-terminal pro-brain natriuretic peptide,myeloperoxidase(MPO),high-sensitivity C-reactive protein(hsCRP),and systolic and diastolic blood pressure.To evaluate the possible predictors of observed changes in the SGLT2i arm during follow-up,a rise in stroke volume index,body mass index(BMI)decrease,and lack of heart rate increase,linear regression analysis was performed.RESULTS There was a greater reduction of MPO,hsCRP,GLS,and blood pressure in the groups with higher baseline values of mentioned parameters irrespective of the therapeutic arm after 6 months of follow-up.Significant independent predictors of heart rate decrease were a reduction in early mitral inflow velocity to early diastolic mitral annular velocity at the interventricular septal annulus ratio and BMI,while the predictor of stroke volume index increase was SGLT2i therapy itself.CONCLUSION SGLT2i affect body composition,reduce cardiac load,improve diastolic/systolic function,and attenuate the sympathetic response.Glycemic control contributes to the improvement of heart function,blood pressure control,oxidative stress,and reduction in inflammation.
文摘Many patients prioritize the ability to return to sports following shoulder replacement surgeries, including total shoulder arthroplasty(TSA), reverse total shoulder arthroplasty(RTSA), and hemiarthroplasty(HA). While activity levels after hip and knee replacements have been well-established in the literature, studies on this topic in the field of shoulder arthroplasty are relatively limited. A review of the literature regarding athletic activity after shoulder arthroplasty was performed using the PubMed database. All studies relevant to shoulder arthroplasty and return to sport were included. The majority of patients returned to their prior level of activity within six months following TSA, RTSA, and shoulder HA.Noncontact, low demand activities are permitted by most surgeons postoperatively and generally have higher return rates than contact sports or high-demand activities. In some series, patients reported an improvement in their ability to participate in sports following the arthroplasty procedure. The rates of return to sports following TSA(75%-100%) are slightly higher than those reported for HA(67%-76%) and RTSA(75%-85%). Patients undergoing TSA, RTSA, and shoulder HA should be counseled that there is a high probability that they will be able to return to their preoperative activity level within six months postoperatively. TSA has been associated with higher rates of return to sports than RTSA and HA,although this may reflect differences in patient population or surgical indication.
文摘Background:Team-sport players have a particularly high injury risk.Although female sex is considered a risk factor,it is still unknown whether female and male team-sport players,in fact,differ in their injury rates.We aimed to compare injury rates between female and male players by systematically reviewing and meta-analyzing injury surveillance studies of both sexes in order to evaluate sex-specific differences in team-sport injuries.Methods:Studies that prospectively collected injury data for high-level female and male players(age≥16 years)in basketball,field hockey,football(soccer),handball,rugby(union and sevens),and volleyball were included.Two reviewers(AZ and ALR)independently assessed study quality and extracted data for overall,match,training,and severe injuries(>28 days’time loss)as well as data regarding injury locations and types.Incidence rate ratios(IRRs)were pooled in a meta-analysis,and meta-regression analysis was performed when 10 or more studies were available.Results:Of 20 studies,9 studies reported injury data from football,3 studies from rugby,3 studies from handball,1 study from basketball,1 study from field hockey,2 studies from volleyball,and 1 study from basketball and field hockey.For overall injuries,the pooled IRR=0.86(95%confidence interval(95%CI):0.76-0.98)indicated significantly more injuries in male than in female players.For injury location,the pooled IRR showed higher injury rates in male athletes than in female athletes for upper extremity,hip/groin,thigh,ande foot injuries.Female players had a significantly higher rate of anterior cruciate ligament injuries(IRR=2.15,95%CI:1.27-3.62)than male players.No significant sex-specific differences in IRR were found for match,training,severe injuries,concussions,or ankle sprains.Conclusion:Our meta-analysis provides evidence for sex-specific differences in the injury rates in team sports.Further epidemiological studies including both sexes in sports other than football are needed in order to strengthen the evidence.
文摘Remember way back when?When we were kids?We played games like soccer,basketball,rugby,and volleyball because they were fun.If we stayed with it long enough(and became good enough)we might have played competitively,where the objective was to win.Herman Edwards,a former head coach in the National Football League(NFL)。
文摘The prevalence of pediatric obesity continues to increase worldwide,bringing with it various metabolic,functional,social,and psychological complications.1 Both the prevention and treatment of childhood obesity must be based on multidisciplinary approaches combining nutrition,physical activity(PA),and psychological support.2 As an essential element of these multicomponent strategies,regular physical activity has been acknowledged as having beneficial effects on children's and adolescents,body composition,physical fitness,and metabolic profile,as well as on their health-related quality of life,social and psychological health,and academic achievement.3,4 Given that only a relatively small proportion of children and adolescents meet the public health recommendations for PA,5 and given that weight loss exercise-based interventions suffer from a high attrition rate,there is a clear need for appropriate PAs.
文摘Quantifying the potential market of sports licenses is key in order for National Governing Bodies of sport （NGBs） to be able to design good strategic planning. We compared the classical methods of univariate prediction and the Autoregressive Integrated Moving Average （ARIMA） methods. Reliability of the available data was verified with the Time Series Regression with ARIMA Noise, Missing and Outliers （TRAMO） method, and the existence of a trend was verified using Daniel＇s test. For the purposes of this study--the researches collected and analysed secondary data from a 40-year series in 45 sports in Spain covering a very long period of time in a variety of sport disciplines. The study shows that, with the available data, short- and mid-term forecasting is possible in a number of sports, but not in all of them. It also proves that Holt＇s classical method of exponential smoothing is the one that yields best results. Golf, Basketball, Athletics and Hunting NGB show worrying prospects of decline levels and need an immediate change in the strategic plans. Other than for forecasting the evolution of athletes in the mid-term in order to improve strategic planning in NGBs, the present findings can be useful for public authorities to define their aid policies for NGBs, and they can also help companies in the industry to anticipate market developments.
文摘The aim of the study is to examine the undergraduate program courses of the universities providing training in Sports Management in Turkey. In this study, electronic screening method was used via web sites of universities. 80 Sports Management Departments （SMD） were found and only 20 of them which were up to date were analyzed. 2016-2017 academic year curriculums were examined. All universities examined were state universities. The courses were grouped as Compulsory-Elective, Theoretical-Practical and Total number of course-hour and credit. The percentages of the courses were calculated over the total course hours for that group.
文摘Winter sports, including those with a focus on gliding with skis on snow, have become extremely complex in the last few decades. During the Olympic Games held in Pyeongchang, Republic of Korea, in 2018, a greater number of different skiing competitions took place: alpine skiing with giant slalom, downhill, slalom, and super-G and alpine combined; biathlon with 10-km sprint, 12.5-km pursuit, 15-km mass start, 20-km individual, and a 4×7.5-km relay; cross-country skiing with 6 different kinds of races including short, medium and long distances, classical and skating techniques, and individual and mass start; free-style skiing with aerials, moguls, ski cross, ski halfpipe, and ski slopestyle; Nordic skiing combined with ski jumping on large and normal hills, followed by cross-country skiing over 10 km; and snowboard with big air, half pipe, parallel giant slalom, slope style, and snowboard cross.
文摘Sport tourism has a good effect against the development of tourism in general. Sport and tourism are the two disciplines and two different studies but they can be put together so that mutually beneficial. In sports, there are some tourism elements. Conversely through tourism, sports can be nurtured and developed. Another goal is to serve as a tool to introduce and to recognize sport, improve fitness and preparation exercise. In 2006, the Indonesian government began to develop sports industry which is a new field of study in this country. Ministry of Youth and Sports launched a resurgence sports industry in Indonesia. Sport Tourism is very likely developed in Indonesia. Indonesia is a country rich in natural resources which are very beautiful. Indonesia is also rich in diverse cultures. Indonesia is also rich of their human resources. The economic value can be profitable for the state, government and society. Some physics activities in the tourism sports of which are mountaineering, climbing, sport diving, mountain bike, out bond and traditional sport. Conversely, tourism events that can be collaborated with sports activities in Indonesia are Lake Toba festival, Serayu River Festival, Borobudur festival, etc. Finally, if the program is managed well in Indonesia, it will help this country to develop sports tourism sports and encourage people to participate in sports activities. It can also make potential athletes seedlings in various sports. Output of this activity is to encourage public awareness of the sport and responsible for sports performance.
文摘Sports are a meaningful context in which many young people participate,and youth sports teams may be a viable way to promote optimal development.Sports comprises all forms of physical activities that contribute to physical fitness,mental well-being and social interaction.Participation in sport improves the development of peer relationships,establishes the notion of trust and builds teamwork skills.The purpose of this study was to see the impact of sports participation on intelligence among boys.The present study was conducted on 300 male subjects between age group 14 and 17 years.Subjects were divided into following three groups(Group 1-Team Sports Group,Group 2-Individual Sports Group,Group 3-Non-participant Group)using a questionnaire for Sports Activity participation survey.Each group has 100 students.To assess intelligence of the selected subjects,verbal intelligence test prepared by Dr.P.Srinivasan was adopted.Appropriate tool was used to assess the parameters.The results show that majority i.e.64.7%of the subjects were found to be average intelligent and 22.7 superiorly intelligent.It was revealed that sports participation has no association withrelation to intelligence(IQ)and revealed that there was no significant effect found on intelligence level of the subjects who participated in sports as well as the non-participants.
文摘The sample consisted of sixteen man of aged average 24.5 year, average height 181.9 cm and weight 80.4 kg. The average of static pulse rate was 56.4 beats min1. The average heart rate max was 189.7 ± 7.8 beats minl. For the calculation of HRmax （maximal heart rate）, a mathematical figure HRmax = 207 - （0.7 × age） was used. Probands have participated on the same day on a tournament in beach and handball tournament. HR （heart rate） was monitored via Sport Tester Polar. The results were evaluated by Polar software. The data was statistically compiled with the use of arithmetic average and standard deviation. The players played three matches in beach volleyball on one set to 21 points （necessary difference of 2 points）. One set lasted approximate 13.5 min. After a break, they went to play three matches in beach handball. The average HR during beach volleyball was 149.5 ±14.1 beats min-1 and 164.3 ± 14.5 beats min1 in beach handball. In beach volleyball, we also focused on players＇ intensity load differences 172 ±14.1 beats minland goalkeepers 156.5 ± 16.6 beats min1. In the beach volleyball, players spend most of their playing time on the playing area in the zone intensity load 80%-90% HRmax （36% playing time）. In the beach handball, players spend most of their playing time on the playing area in the zone intensity load 90%-100% HRmax （39% playing time）.
文摘The purposes of this study were to examine the relationships between providing and receiving social supports with teammates, and to clarify the particularities of Japan, based on an examination of differences between Japan and the U.S. The subjects were 123 collegiate student＇s athletes from Japan and 115 from the United States. They participated organized sports activities in their universities （including intramural and varsity level）. The participants completed questionnaires measuring the providing and receiving social supports for sports participation and persistency. Providing and Receiving Social Support Scale for Sports Team （Hagiwara and Isogai, 2014） were adopted to investigate the amount of social supports with teammates in a sports team. The results of correlations in providing and receiving social supports demonstrated that the amount of providing social support for teammates related to the amount of receiving social support from teammates in both Japanese and American student＇s athletes. The results of comparison Japan and the U.S. indicated that American student＇s athletes provided more social supports for teammates than Japanese. The present findings might be an important material to better understand Japanese student＇s athletes.
文摘Objectives:This research based on the theoretical framework of globalisation focuses on the development of gender equality policy in the Olympic Movement and the implementation of IOC’s gender equality policy in the context of Chinese elite volleyball.Methods:In addition to documentary analysis,17 semistructured interviews were conducted with key insiders within Chinese elite volleyball system to provide a comprehensive understanding of the IOC’s gender equality policy implementation.The analysisinvolved perspectives of athletes’participation,coaching positions,and leadership roles according to three main elements of the IOC’s gender equality policy.Results:Thefindings demonstrated that the responses of Chinese elite volleyball to IOC’s gender equality policy are participative,conflictual,and passive in terms of the gender balance of athletes’participation,coaches’positions,and the representation of leadership roles respectively.Conclusions:IOC recommended subordinated stakeholders including NOCs to implement gender equality policy.The attitude of Chinese elite volleyball governing body towards gender equality is generally positive.However,IOC’s gender equality policy is not consistently transferred at national level.Policy might be implemented with symbolic measure in China without monitoring system.Referees should be included in policy contents in addition to athletes,coaches and leaders.In addition,since IOC’s gender equality policy and statistics have been keeping updated,further results with respect to the case of volleyballshould be demonstrated in future research.
文摘The retention of customers is fundamental to the success of sport organizations for a variety of reasons,not the least of which is it is less expensive for an organization to keep a current customer than to gain a new one.Since customer repurchase intention is an important indicator to predict repurchase behavior,exploring the factors that influence this behavior has important theoretical and practical implications in the commercial martial arts school market.Although previous research provides a foundation for the factors that influence a customer's repurchase intention,additional empirical work is warranted.This study was designed to integrate the findings of previous studies and examine how utilitarian factors(perceived value and switching cost),a hedonic factor(perceived enjoyment),and social/psychological factors(confirmation and satisfaction)directly or indirectly influenced consumers'repurchase intentions in the context of commercial martial arts schools.The results indicated that customer satisfaction had the strongest impact on customer repurchase intention,followed by perceived enjoyment,switching costs,confirmation,and perceived value.

文摘Melatonin(N-acetyl-5-methoxytryptamine)is known as the hormone of darkness because it is synthesized at night and involved in regulating the circadian clock.The hormone is primarily synthesized by the vertebrate pineal gland,but is ubiquitous among invertebrates,unicellular organisms,plants,and even cyanobacteria(Hattori and Suzuki,2024).Melatonin is well-conserved evolutionarily and possesses several physiological functions,such as immune response,bone and glucose metabolism,and memory formation besides regulating the circadian rhythm.
文摘Challenges in the diagnosis and treatment of Parkinson’s disease:Parkinson’s disease(PD)is an increasingly prevalent neurodegenerative disease,at first sight primarily characterized by motor symptoms,although non-motor symptoms also constitute a major part of the overall phenotype.Clinically,this disease cannot be diagnosed reliably until a large part of the vulnerable dopaminergic neurons has been irretrievably lost,and the disease progresses inexorably.New biological criteria for PD have been proposed recently and might eventually improve early diagnosis,but they require further validation,and their use will initially be restricted to a research environment(Darweesh et al.,2024).
