摘要
用双标水方法测定了１２名６～８岁体操运动员（男女各６名）的总能量消耗（ＴＥＥ）。同时用开放式间接测热法检测了他们的基础代谢率（ＢＭＲ）。根据总能量消耗与基础代谢率的比值推算出每日体力活动水平（ＰＡＬ），用ＴＥＥ－（ＢＭＲ＋０．１ＴＥＥ）表示其在体力活动上的能量消耗（ＥＣＰＡ）。结果表明：儿童体操运动员的总能量消耗平均为８．３９±１．０８ＭＪ／ｄ（男：８．６７±１．４２ＭＪ／ｄ；女：８．１１±０．５９ＭＪ／ｄ，Ｐ＞０．０５），分别高于ＷＨＯ和我国推荐的每日能量需要量标准的３６％（Ｐ＜０．００１）和１３％（Ｐ＜０．０１）。基础代谢率平均为４．２２±０．３６ＭＪ／ｄ（男：４．４５±０．３４ＭＪ／ｄ；女：３．９９±０．２１ＭＪ／ｄ，Ｐ＜０．０５）。体力活动水平平均为１．９８±０．２９（男：１．９６±０．３５；女：２．０４±０．１５，Ｐ＞０．０５）；体力活动的能量消耗平均为３．３４±１．００ＭＪ／ｄ（男：３．３５±１．３９ＭＪ／ｄ；女：３．３２±０．５０ＭＪ／ｄ，Ｐ＞０．０５）。儿童体操运动员的总能量消耗高于ＲＤＡ，与其每日从事运动训练时消耗大量能量有关。
The total energy expenditure (TEE) was first measured by doubly labelled water (DLW) method in twelve elite young gymnasts (6 8 years old,6 boys and 6 girls).Also,the basal metabolic rate (BMR) of each child was determined with open circuit indirect calorimetry.The physical activity level (PAL) and energy cost for physical activity (ECPA) were estimated from the ratio of TEE to BMR and TEE-(BMR×0.1TEE) separately.The mean TEE in young gymnasts was 8.39±1.08MJ/d(boys:8.67±1.42MJ/d;girls:8.11±0.59MJ/d,P>0.05),which was significantly 36% (P<0.001) and 13% (P<0.01) higher than current international and Chinese recommendations for energy intake.The mean BMR of children was 4.22±0.36 MJ/d(boys:4.45±0.34 MJ/d;girls:3.99±0.21 MJ/d,P<0.05).Their mean PAL was 1.98±0.29(boys:1.96±0.36;girls:2.04±0.15,P>0.05) and ECPA was 3.34±1.00MJ/d (boys:3.35±1.39MJ/d;girls:3.32±0.05MJ/d,P>0.05).Therefore,the evidence that TEE of young gymnasts was higher than RDA may be explained due to the high energy output for heavy physical activity in these gymnasts.
