There has been remarkable development in the scope and quality of rock climbing in recent years. However, there are scant data on the anthropometry, strength, endurance and flexibility of rock climbers. The aim of this study was to compare these characteristics in three groups of subjects-elite rock climbers, recreational climbers and non-climbers. The 30 male subjects were aged 28.8 +/- 8.1 (mean +/- S.D.) years. Group 1 (n = 10) comprised elite rock climbers who had led a climb of a minimum standard of 'E1' (E1-E9 are the highest climbing grades) within the previous 12 months; Group 2 (n = 10) comprised rock climbers who had achieved a standard no better than leading a climb considered 'severe' (a low climbing grade category); and Group 3 (n = 10) comprised physically active individuals who had not previously done any rock climbing. The test battery included tests of finger strength [grip strength, pincer (i.e. thumb and forefinger) strength, finger strength measured on climbing-specific apparatus], body dimensions, body composition, flexibility, arm strength and endurance, and abdominal endurance. The tests which resulted in significant differences (P < 0.05) between the three groups included the bent arm hang (elite 53.1 +/- 1.32 s; recreational 31.4 +/- 9.0 s; non-climbers 32.6 +/- 15.0 s) and pull-ups (elite 16.2 +/- 7.2 repetitions; recreational 3.0 +/- 4.0 reps; non-climbers 3.0 +/- 3.9 reps); for both tests, the elite climbers performed significantly better than the recreational climbers and non-climbers. Regression procedures (i.e. analysis of covariance) were used to examine the influence of body mass and length. Using adjusted means (i.e. for body mass and leg length), significant differences were obtained for the following: (1) finger strength, grip 1, four fingers (right hand) (elite 447 +/- 30 N; recreational 359 +/- 29 N; non-climbers 309 +/- 30 N), (2) grip strength (left hand) (elite 526 +/- 21 N; recreational 445 +/- 21 N; non-climbers 440 +/- 21 N), (3) pincer strength (right hand) (elite 95 +/- 5 N; recreational 69 +/- 5 N; non-climbers 70 +/- 5 N) and (4) leg span (elite 139 +/- 4 cm; recreational 122 +/- 4 cm; non-climbers 124 +/- 4 cm). For tests 3 and 4, the elite climbers performed significantly better than the recreational climbers and non-climbers for any variable. These results demonstrate that elite climbers have greater shoulder girdle endurance, finger strength and hip flexibility than recreational climbers and non-climbers. Those who aspire to lead 'E1' standard climbs or above should consider training programmes to enhance their finger strength, shoulder girdle strength and endurance, and hip flexibility.
近年来,攀岩运动在范围和质量方面都有了显著发展。然而,关于攀岩者的人体测量学、力量、耐力和柔韧性的数据却很少。本研究的目的是比较三组受试者——精英攀岩者、业余攀岩者和非攀岩者——的这些特征。30名男性受试者的年龄为28.8±8.1(平均±标准差)岁。第一组(n = 10)由精英攀岩者组成,他们在过去12个月内完成了至少达到“E1”标准(E1 - E9是最高攀岩等级)的攀岩;第二组(n = 10)由攀岩水平不超过完成被认为是“难度较大”(较低攀岩等级类别)攀岩的攀岩者组成;第三组(n = 10)由之前从未进行过任何攀岩运动的身体活跃个体组成。测试项目包括手指力量测试[握力、捏力(即拇指和食指)、在特定攀岩器械上测量的手指力量]、身体尺寸、身体成分、柔韧性、手臂力量和耐力以及腹部耐力。在三组之间产生显著差异(P < 0.05)的测试包括屈臂悬垂(精英组53.1±1.32秒;业余组31.4±9.0秒;非攀岩者组32.6±15.0秒)和引体向上(精英组16.2±7.2次重复;业余组3.0±4.0次;非攀岩者组3.0±3.9次);对于这两项测试,精英攀岩者的表现均显著优于业余攀岩者和非攀岩者。使用回归程序(即协方差分析)来检验体重和身高的影响。采用调整后的均值(即针对体重和腿长),在以下方面获得了显著差异:(1)手指力量,握力1,右手四指(精英组447±30牛;业余组359±29牛;非攀岩者组309±30牛),(2)握力(左手)(精英组526±21牛;业余组445±21牛;非攀岩者组440±21牛),(3)捏力(右手)(精英组95±5牛;业余组69±5牛;非攀岩者组70±5牛)和(4)腿间距(精英组139±4厘米;业余组122±4厘米;非攀岩者组124±4厘米)。对于测试3和4,精英攀岩者在任何变量上的表现均显著优于业余攀岩者和非攀岩者。这些结果表明,精英攀岩者比业余攀岩者和非攀岩者具有更强的肩带耐力、手指力量和髋部柔韧性。那些渴望完成“E1”标准或更高标准攀岩的人应考虑制定训练计划以增强他们的手指力量、肩带力量和耐力以及髋部柔韧性。
