This study examined the salivary hormone and immune responses of elite female athletes to 3 different resistance exercise schemes. Fourteen female basketball players each performed an endurance scheme (ES-4 sets of 12 reps, 60% of 1 repetition maximum (1RM) load, 1-minute rest periods), a strength-hypertrophy scheme (SHS-1 set of 5RM, 1 set of 4RM, 1 set of 3RM, 1 set of 2RM, and 1set of 1RM with 3-minute rest periods, followed by 3 sets of 10RM with 2-minute rest periods) and a power scheme (PS-3 sets of 10 reps, 50% 1RM load, 3-minute rest periods) using the same exercises (bench press, squat, and biceps curl). Saliva samples were collected at 07:30 hours, pre-exercise (Pre) at 09:30 hours, postexercise (Post), and at 17:30 hours. Matching samples were also taken on a nonexercising control day. The samples were analyzed for testosterone, cortisol (C), and immunoglobulin A concentrations. The total volume of load lifted differed among the 3 schemes (SHS > ES > PS, p < 0.05). Postexercise C concentrations increased after all schemes, compared to control values (p < 0.05). In the SHS, the postexercise C response was also greater than pre-exercise data (p < 0.05). The current findings confirm that high-volume resistance exercise schemes can stimulate greater C secretion because of higher metabolic demand. In terms of practical applications, acute changes in C may be used to evaluate the metabolic demands of different resistance exercise schemes, or as a tool for monitoring training strain.
本研究考察了 3 种不同的抗阻运动方案对精英女性运动员的唾液激素和免疫反应的影响。14 名女性篮球运动员分别进行了耐力方案(ES-4 组 12 次重复,60%的 1 次重复最大重量(1RM)负荷,1 分钟休息时间)、力量-肥大方案(SHS-1 组 5RM、1 组 4RM、1 组 3RM、1 组 2RM 和 1 组 1RM,休息 3 分钟,然后进行 3 组 10RM,休息 2 分钟)和力量方案(PS-3 组 10 次重复,50%的 1RM 负荷,3 分钟休息时间),均使用相同的运动(卧推、深蹲和二头肌弯举)。在 07:30 小时、09:30 小时(运动前)、运动后和 17:30 小时采集唾液样本。在非运动控制日也采集了匹配样本。分析了睾酮、皮质醇(C)和免疫球蛋白 A 的浓度。3 种方案的总负荷量不同(SHS>ES>PS,p<0.05)。与对照值相比,所有方案后运动后的 C 浓度均升高(p<0.05)。在 SHS 中,运动后 C 的反应也高于运动前(p<0.05)。目前的研究结果证实,高负荷抗阻运动方案由于代谢需求较高,可以刺激更多的 C 分泌。在实际应用中,C 的急性变化可用于评估不同抗阻运动方案的代谢需求,或作为监测训练负荷的工具。
