This study was conducted to validate and evaluate the "Hit & Turn Tennis Test", an acoustically progressive on-court endurance test for tennis players. Ninety-eight competitive tennis players (53 males, 45 females) of different age groups participated in the study. For validation, the adult male players completed three Hit & Turn tests, one on a clay court and two on a carpet surface, a tennis-specific ball machine test and an incremental treadmill run in a randomized order. A stronger correlation between maximal performance (r = 0.81, P < 0.01) and maximal oxygen uptake (r = 0.96, P < 0.01) was observed between the Hit & Turn test and the ball machine test, than between the Hit & Turn test and the treadmill test. For test-retest, we found a significant correlation between maximal performance on the same (r = 0.83, P < 0.01) and on different surfaces (r = 0.74, P < 0.01). During test evaluation, maximal performance was higher in males than in females (P < 0.01) and increased by consecutive age group in boys (P < 0.01) but not in girls (P = 0.97). In conclusion, Hit & Turn maximum test performance can be recommended as a valid and reliable indicator for tennis-specific endurance.
本研究旨在验证和评估“击球转身网球测试”（Hit & Turn Tennis Test），这是一种针对网球运动员的声学渐进式场上耐力测试。98 名不同年龄组的竞技网球运动员（男性 53 名，女性 45 名）参加了这项研究。为了验证，成年男性运动员在随机顺序下完成了三次击球转身测试，一次在红土场地上，两次在地毯表面上，使用专门的网球球机测试和递增跑步机跑步。击球转身测试与球机测试之间的最大性能（r = 0.81，P < 0.01）和最大摄氧量（r = 0.96，P < 0.01）之间的相关性比击球转身测试与跑步机测试之间更强。对于测试-重测，我们发现相同表面（r = 0.83，P < 0.01）和不同表面（r = 0.74，P < 0.01）上的最大性能之间存在显著相关性。在测试评估中，男性的最大性能高于女性（P < 0.01），并且男孩的连续年龄组（P < 0.01）增加，但女孩没有（P = 0.97）。总之，击球转身最大测试表现可以被推荐为网球专项耐力的有效和可靠指标。
