Travis, SK, Mizuguchi, S, Stone, MH, Sands, WA, and Bazyler, CD. Preparing for a national weightlifting championship: A case series. J Strength Cond Res 34(7): 1842-1850, 2020-This study aimed to characterize psychological, physiological, and performance changes of a high-level female (24.5 years; 53.8 ± 0.3 kg; 155.4 cm) and male (25.8 years; 92.7 ± 1.2 kg; 189 cm) weightlifter over 28 weeks while preparing for a national championship. Body mass, hydration, psychological inventories, serum biomarkers, vastus lateralis muscle cross-sectional area (CSA), and squat jump (SJ) performance were assessed weekly beginning 11 weeks from the competition date. Weightlifting performance goals were met for the female athlete (actual total = 159 kg) but not for the male athlete (actual total = 292 kg). Reductions in vastus lateralis CSA possibly took place the week leading into competition for both athletes. Both athletes reported positive recovery-stress states on the day of competition relative to baseline values. Fluctuations between steroid hormone concentrations and inflammatory markers were unpredictable and inconsistent for both athletes throughout the training program. Unloaded SJ height and rate of force development were the highest on competition day for both athletes. Based on these findings, it is possible for high-level male and female weightlifters to achieve and maintain peak preparedness 3-4 days before competition following a 1-week overreach and 3-week exponential taper, where training volume-load is reduced by half and intensity maintained or slightly increased relative to pretaper values. Furthermore, the short recovery and stress scale and SJ testing seem to be useful tools for sport scientists and coaches when monitoring high-level weightlifters preparing for competition.
崔维斯、水口、斯通、桑兹和巴泽勒。备战全国举重锦标赛:病例系列研究。《力量与调节研究杂志》34(7):1842-1850,2020 年-本研究旨在描述一名高水平女性(24.5 岁;53.8±0.3 公斤;155.4 厘米)和一名高水平男性(25.8 岁;92.7±1.2 公斤;189 厘米)举重运动员在为全国锦标赛做准备的 28 周期间的心理、生理和表现变化。从比赛日期前 11 周开始,每周评估一次体重、水合作用、心理问卷、血清生物标志物、股外侧肌横截面积(CSA)和深蹲跳(SJ)表现。女运动员达到了举重成绩目标(实际总成绩=159 公斤),但男运动员没有(实际总成绩=292 公斤)。两名运动员的股外侧肌 CSA 可能在比赛前一周减少。与基线值相比,两名运动员在比赛当天报告的恢复-应激状态均为积极。类固醇激素浓度和炎症标志物的波动对两名运动员在整个训练计划中都是不可预测且不一致的。在比赛当天,未负重 SJ 高度和力量发展率对两名运动员而言都是最高的。根据这些发现,高水平的男性和女性举重运动员在经历 1 周的超越和 3 周的指数 taper 后,有可能在比赛前 3-4 天达到并保持最佳状态,其中训练量负荷减少一半,强度保持或略高于 taper 前的值。此外,短时间的恢复和应激量表以及 SJ 测试似乎是运动科学家和教练在监测为比赛做准备的高水平举重运动员时的有用工具。
