The present study investigated the effects of traditional resistance training (TRT) and functional resistance training (FRT) on arterial stiffness and muscular strength in healthy young men.
This randomized controlled trial included 29 untrained healthy young men aged 18-29 years who were randomly divided into two groups, namely, TRT group ( = 15) and FRT group ( = 14). All participants underwent numerous tests, such as those for body composition, cardio-ankle vascular index, blood pressure, heart rate, and maximal strength before and after the 6-week training program. The exercise training comprised whole-body strength training exercises 3 days a week for 6 weeks. The total training volume and number of sets (4-5 sets) were kept constantly similar in each group. The TRT group completed 4-5 sets of 8-12 repetitions [70% of 1 repetition maximum (1RM)], whereas the FRT group completed 4-5 sets of 15-22 repetitions (40% 1RM).
The TRT and FRT groups exhibited equally significantly increased maximal strength (within group: both < 0.01). Furthermore, the independent -test showed that the differences between the two groups in terms of changes in maximal strength were no significant (between group: both > 0.05). Additionally, significant main effects of time (pre vs. post) were observed for the left and right cardio-ankle vascular indices ( < 0.05); however, no significant difference were observed between the groups. For body compositions outcome measures, no significant differences between groups were observed.
Six weeks of FRT and TRT exhibit no difference in terms of effects on arterial stiffness and muscular strength.
本研究调查了传统阻力训练(TRT)和功能性阻力训练(FRT)对健康年轻男性动脉僵硬度和肌肉力量的影响。
这项随机对照试验纳入了29名年龄在18 - 29岁之间未经训练的健康年轻男性,他们被随机分为两组,即TRT组(n = 15)和FRT组(n = 14)。所有参与者在为期6周的训练计划前后都接受了多项测试,如身体成分、心踝血管指数、血压、心率和最大力量测试。运动训练包括每周3天的全身力量训练练习,持续6周。每组的总训练量和组数(4 - 5组)保持大致相似。TRT组完成4 - 5组,每组8 - 12次重复[1次重复最大值(1RM)的70%],而FRT组完成4 - 5组,每组15 - 22次重复(1RM的40%)。
TRT组和FRT组的最大力量均显著增加(组内:均P < 0.01)。此外,独立样本t检验显示两组在最大力量变化方面的差异不显著(组间:均P > 0.05)。此外,观察到左右心踝血管指数在时间(训练前与训练后)上有显著的主效应(P < 0.05);然而,两组之间未观察到显著差异。对于身体成分测量结果,两组之间未观察到显著差异。
六周的FRT和TRT在对动脉僵硬度和肌肉力量的影响方面没有差异。
