| 摘 要： | 目的:探究我国男子橄榄球运动员的有氧能力和比赛时的能量消耗,为精准化训练和比赛时营养策略的制定提供理论依据。方法:以18名男子橄榄球运动员(健将级)为研究对象,分别进行最大摄氧量(VO2max),乳酸阈(LT)和conconi场地测试来评定其有氧能力,并比较前、后锋之间的供能差异,用wGT3X加速度计结合团队心率探究比赛时的能量消耗,所得数据进行独立样本t检验。结果:本次检测的橄榄球运动员相对最大摄氧量较差为(42.05±3.69) ml/min·kg-1,前峰队员相对最大摄氧量为(38.83±3.52) ml/min·kg-1、后锋队员相对最大摄氧量为(47.31±3.17)ml/min·kg-1,二者之间的差异有统计学意义(P＜0.05);血乳酸阈测定在7 min时出现血乳酸拐点,后锋的血乳酸阈值要高于前锋运动员;conconi场地测试与实验室VO2max有较高的相关性(r=0.772)。比赛中平均能量消耗上半场约为(276.94±18.08) kcals,下半场约为(225.58±22.86) kcals,下半场的能耗小于上半场(P＜0.05)。结论:英式7人制橄榄球运动员有氧能力较弱,且前、后锋队员存在差异。

| Abstract: | Objective: To explore aerobic power and energy expenditure of high level rugby players in China, which provide experimental basis for accurate training and nutritional strategy in match-play. Methods: Eighteen master rugby players were selected as research subjects. The parameters such as VO2max, lactic aicd threshold (LT) and modify conconi test were measured respectively. The differences of energy were compared between the forward and the defender. The data were analyzed by independent sample t test. Results: The VO2max(42.05±3.69 ml/min·kg-1) of rugby players was poorer. The VO2max of the forward was 38.83±3.52 (ml/min·kg-1), and that of the defender was 47.31±3.17 (ml/min·kg-1),and there was significant difference between the forwards and the defenders (P＜0.05). The LT of the defenders was obviously higher than that of the forwards. Modifier conconi test had a high correlation (r = 0.772) with VO2max. The average energy consumption in the first half of the game was about(276.94±18.08)kcals, the second half was(225.58±22.86)kcals, and the second half was less than the first half (P＜0.05).Conclusion: The aerobic power is different between the forwards and the defenders. The power of aerobic of Chinese players is weaker than that of the foreign rugby players. |
