文摘Affective valence is typically positive at exercise intensities below the lactate threshold,yet more aversive responses occur at supra-threshold intensities.Nevertheless,the physiological and psychological predictors of affective valence during supramaximal intensities including short sprint interval training(sSIT)have not yet been elucidated.Seventeen(7 women/10 men)moderately active young adults(age=[28.2±5.6]years;VO2max[maximum oxygen consumption]=[52.9±8.1]mL·kg^(-1)·min^(-1);BMI[body mass index]=[242]kg·m^(-2))completed four low-volume running sSIT sessions(10^(-4)s efforts with 30 s of passive recovery).We recorded participants’heart rate(HR),root mean square of successive differences of normal RR intervals(RMSSD),heart rate recovery(HRR),ratings of perceived exertion(RPE),feeling scale(FS),intention and self-efficacy during,and after each session.Overall,no significant correlation(p>0.05)was found between FS and baseline clinical outcomes.No significant correlation(p>0.05)was detected between FS and any training parameter.No significant correlations were noted between FS and exercise task self-efficacy and intentions(p>0.05).The regression model was significant(F_(3,61)=5.57;p=0.002)and only three variables significantly entered the generated model:ΔHRR_(end-120s end)(p=0.002;VIF=2.58;40.8%),time≥90%HR_(peak)(p=0.001;VIF=1.26;31.6%),and RMSSD_(end)(p=0.025;VIF=2.23;27.6%).These findings suggest that HR-based measures,particularly those related to in-task stress(time≥90%HR_(peak))and acute recovery(ΔHRR_(end-120s end),and RMSSD_(end)),may predict affective valence during real-world sSIT.
