简要总结
This study evaluate whether resistance training variables modulate the fatigability (power-duration relationship) and physical performance in adults and older adults
详细描述
The resistance training variables manipulation is utilized for maximize the results of resistance training. However it is unclear whether the resistance training variables manipulation modulates the fatigability (i.e. power-duration relationship) and whether this explains the improvement on physical performance (i.e. gait speed, sit-to-stand and timed up and go tests).

研究组 & 干预措施
Lower load resistance training (LL)
In the LL group, postmenopausal women will perform the resistance training with moderate volume (i.e. three sets per exercise performed until or close to failure) and low load (i.e. 30% of 1RM)
干预措施: Resistance training, LL (Other)
Higher load resistance training (HL)
In the HL group, postmenopausal women will perform the resistance training with moderate volume (i.e. three sets per exercise performed until or close to failure) and high load (i.e. 80% of 1RM)
干预措施: Resistance training, HL (Other)
Higher volume resistance training (HVHL)
In the HVHL group, postmenopausal women will perform the resistance training with high volume (i.e. six sets per exercise performed until or close to failure) and high load (i.e. 80% of 1RM)
干预措施: Resistance training, HVHL (Other)
Control group, (CG)
In CG, the postmenopausal women group will not perform exercise
干预措施: Control group, CG (Other)
结局指标
主要结局
Fatigability
时间窗: Changes in fatigability measure (e.g. baseline and after 12 weeks of intervention)
The fatigability will be evaluate by 60 maximum voluntary isometric contractions (3 s contraction, 2 s rest) in knee extensors at 70 degree.
次要结局
- Physical Performance(Changes in physical performance measure (e.g. baseline and after 12 weeks of intervention))
