The aim of the study was to investigate the effect of two long-term reduced concurrent training modalities, in which participants performed one training session every either 7 or 14 days, after 12 weeks of systematic concurrent resistance and aerobic training, on lower extremities' muscle strength, power, and morphology in young females. After the 12-week training period, participants were assigned into three groups and performed either one training session every 7 days (G7) or once every 14 days (G14), or detraining (GD), for 12 weeks, followed by 12 additional weeks of detraining. The following were measured before, after the systematic training period, after the end of the reduced training frequency period, and after the end of complete detraining: body composition, leg press 1-RM, countermovement jump, quadriceps cross-sectional area (CSA), vastus lateralis muscle architecture, and maximum aerobic power. Performance and muscle mass increased after the initial 12-week training period. Thereafter, leg press 1-RM, quadriceps CSA, and aerobic power remained unchanged in the G7 group, but decreased in G14 (-4.4 ± 3.5%; -5.9 ± 1.8%; -9.0 ± 7.8%, respectively, < 0.05), maintaining 95.6 ± 3.5%, 94.1 ± 1.8%, and 91.0 ± 7.8% of the initial training adaptations, respectively. In conclusion, performing one training session every 2 weeks for 3 months may preserve 90 to 95% of the muscle mass/strength and aerobic power adaptations achieved with systematic concurrent training.
本研究的目的是调查在12周系统的抗阻与有氧同步训练后，两种长期减少训练频率的训练模式（参与者每7天或每14天进行一次训练）对年轻女性下肢肌肉力量、功率和形态的影响。在为期12周的训练期结束后，参与者被分为三组，分别每7天（G7组）或每14天（G14组）进行一次训练，或停止训练（GD组），持续12周，随后再进行12周的停止训练。在系统训练期结束前、减少训练频率期结束后以及完全停止训练期结束后，分别测量以下指标：身体成分、腿举1-RM、反向纵跳、股四头肌横截面积（CSA）、股外侧肌结构以及最大有氧功率。在最初的12周训练期后，运动表现和肌肉量有所增加。此后，G7组的腿举1-RM、股四头肌CSA和有氧功率保持不变，但G14组下降（分别为-4.4±3.5%；-5.9±1.8%；-9.0±7.8%，P<0.05），分别维持了初始训练适应性的95.6±3.5%、94.1±1.8%和91.0±7.8%。总之，每2周进行一次训练，持续3个月，可能会保留系统同步训练所获得的90%至95%的肌肉量/力量和有氧功率适应性。
