巴西柔术优秀与非优秀选手和服握力测试之信度与比较

背景:对巴西柔术(BJJ)来说，握力耐力是很重要的。因此，本研究的目的是:a)测试两种单一强度测试的可靠性，即最大静举力(MSL)和最大重复次数(MNR); b)在这些测试中检查优秀和非优秀的jj运动员之间的差异。��:ThirtyBJJplayersparticipatedintotwophases:“A”�totestreliabilityand��“B”tocompareeliteandnon-elite。在“阶段a”中，20名参与者进行了“第一阶段”、“15分钟后”、“第二阶段”和“第二阶段b”，其余10名运动员(非精英)和10名运动员(精英)进行了相同的测试。“他们的横向相关系数”(ICC)、“双向固定模型”(3,1)、“bland - altman图和一致性的极限”用于检验信度，“检验之间的相关性通过pearson相关和独立检验(P<0.05)进行评估”用于比较信度。非精英。结果:不同阶段重复测量的icw值最高(MSL: r=0.99, mnr: r=0.97)。悬浮时间的一致性限制为-6.9至- 2.4秒，平均差异为-2.3秒(CI: -3.3至-1.2秒)，而重复次数的一致性限制为-2.9至-2.3秒，平均差异为-0.3秒(CI: -0.9至-0.3秒)。与非精英相比，精英在两项测试中都表现得更好(P<0.05)(56±10秒)。37±11-sinMSLand�15±4-repvs。8±3-repinMNR)。“mslandmnr在测试期间的绝对值”(r=0.475; p=0.034)，“与测试阶段”(r=0.489; p=0.029)之间存在中度相关性，而“测试阶段”(r=0.615; p=0.004)与“相对值”(r=0.716; p=0.001)之间分别存在中度相关性和高度相关性。结论:这些建议的测试是可靠的，静态和动态握力耐力测试似乎都有区别
