Abstract：
The objective of this study was to explore the effects of a 7-week short sprint interval training (SSIT) with differing in programming volume-loads including progressive (P-SSIT) and nonprogressive (NP-SSIT) approaches on the immunoendocrine, physical fitness attributes and physiological parameters in male wrestlers during the pre-season. Thirty young freestyle wrestlers at the collegiate national-level were included in the study and were divided into three groups: P-SSIT (n = 10), NP-SSIT (n = 10), and an active control group (n = 10). The wrestlers engaged in their specific wrestling training three days weekly, while the P-SSIT and NP-SSIT groups underwent a 7-week SSIT, with scheduling in either progressed or nonprogressed volume-based overloads, three times per week. Before and after the intervention, various aspects of physical fitness (such as 20-m sprint, 4×9-m shuttle run, and maximal strength) and physiological parameters (including cardiorespiratory fitness and anaerobic power output), as well as immunoendocrine responses (such as immunoglobulin-A, testosterone, and cortisol) were measured. Following the training intervention, the control group did not show any significant changes in the variable measured; however, both the P-SSIT and NP-SSIT groups experienced significant improvements (p = 0.001) in physical fitness attributes and physiological parameters with effect sizes ranging from small to very large, and also more adaptive responses compared with control group (p < 0.05). In addition, there were no statistically significant changes observed among the P-SSIT and NP-SSIT groups in terms of immunoendocrine response to training, and physical fitness, as well as physiological parameters (p > 0.05). In conclusion, neither the progressed nor nonprogressed approaches of SSIT demonstrated superior effects on adaptations compared to one another. Therefore, it is recommended for strength and conditioning coaches in wrestling to incorporate both P-SSIT and NP-SSIT into their annual training plan, especially during the pre-season phase, to maximize the physical fitness and physiological parameters of their wrestlers while minimizing changes in immunoendocrine responses.
摘要：
这项研究的目的是探讨7周的短冲刺间隔训练（SSIT）的影响，包括渐进式（P-SSIT）和非渐进式（NP-SSIT）方法对免疫内分泌，季前男性摔跤手的体能属性和生理参数。研究包括30名全国大学级的年轻自由式摔跤手，分为三组：P-SSIT（n=10），NP-SSIT（n=10），和主动对照组(n=10)。摔跤手每周三天进行特定的摔跤训练，而P-SSIT和NP-SSIT组接受了为期7周的SSIT，在进度或非进度的基于卷的重载中进行调度，每周三次。干预前后,身体素质的各个方面(如20米短跑，4×9米穿梭机运行，和最大强度）和生理参数（包括心肺健康和无氧功率输出），以及免疫内分泌反应(如免疫球蛋白A，睾丸激素，和皮质醇）进行了测量。在培训干预之后，对照组没有显示任何显著变化的变量测量;然而,P-SSIT和NP-SSIT组在身体健康属性和生理参数方面都有显着改善（p=0.001），效应大小从小到大，与对照组相比，适应性反应也更多（p<0.05）。此外,P-SSIT和NP-SSIT组在对训练的免疫内分泌反应方面没有观察到统计学上的显着变化，和身体健康，以及生理参数(p>0.05)。总之,SSIT的进步和非进步方法都没有表现出对适应的更好效果。因此,建议摔跤中的力量和条件教练将P-SSIT和NP-SSIT纳入其年度培训计划，特别是在季前阶段，最大限度地提高摔跤手的身体素质和生理参数，同时最大限度地减少免疫内分泌反应的变化。
