该研究的目的是调查两种长期减少并发训练方式的效果,参与者每7或14天进行一次培训,经过12周的系统同时抵抗和有氧训练,下肢肌肉力量,电源,年轻女性的形态。经过12周的训练,参与者被分为三组,每7天(G7)或每14天(G14)进行一次培训,或去训练(GD),12周,然后再进行12周的去训练。以下是之前测量的,经过系统的训练,在减少的训练频率周期结束后,在完全去训练结束后:身体成分,腿部压力机1-RM,反运动跳跃,股四头肌横截面积(CSA),股外侧肌结构,和最大有氧能力。在最初的12周训练期后,性能和肌肉质量增加。此后,腿部压力机1-RM,股四头肌CSA,G7组的有氧能力保持不变,但在G14中下降(-4.4±3.5%;-5.9±1.8%;-9.0±7.8%,分别,p<0.05),保持95.6±3.5%,94.1±1.8%,以及91.0±7.8%的初始训练适应,分别。总之,每2周进行一次为期3个月的训练,可以保持系统的同时训练所达到的肌肉质量/力量和有氧力量适应的90%至95%.
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, p < 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.
