Brief summary
This study evaluate whether resistance training variables modulate the fatigability (power-duration relationship) and physical performance in adults and older adults
Detailed description
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).
Interventions
OTHERResistance training, LL
In LL, the postmenopausal women will be submitted to 12 weeks of Resistance training with moderate volume (i.e. three sets per exercise) and low load (i.e. 30% of one repetition maximum)
OTHERResistance training, HL
In HL, the postmenopausal women will be submitted to 12 weeks of Resistance training with moderate volume (i.e. three sets per exercise) and high load (i.e. 80% of one repetition maximum)
OTHERResistance training, HVHL
In HVHL, the postmenopausal women will be submitted to 12 weeks of Resistance training with high volume (i.e. six sets per exercise) and hig load (i.e. 80% of one maximum repetition)
OTHERControl group, CG
The CG groups do not will performed the exercise.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fatigability | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Physical Performance | Changes in physical performance measure (e.g. baseline and after 12 weeks of intervention) | The physical performance will be evaluate by gait speed tests (e.g. 10m walking at usual and fast pace, 400m walk at usual and fast pace). |
Other
| Measure | Time frame | Description |
|---|---|---|
| Body composition | Changes in body composition (e.g. baseline and after 12 weeks of intervention) | The body composition will be evaluate by dual-energy X-ray absorptiometry (DXA). |
| Muscle strength | Changes in muscle strength (e.g. baseline and after 12 weeks of intervention) | Muscle strength will be assess in all subjects, by the one-repetition maximum (1-RM) test, for dynamic exercises. The 1-RM is defined as the maximal weight that is lifted with proper body alignment and correct lifting technique. |
