Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Decreased late muscle pain verified through visual analogue scale of pain composed of a straight line with 100mm, where 0mm represents absence of pain and 100mm greater pain already felt. Difference greater than 20mm between groups will be considered clinically relevant. Assessments of late muscle pain will be performed pre-protocol fatigue and 24 hours later. | — |
Secondary
| Measure | Time frame |
|---|---|
| Control of basal creatine kinase (CK) change in blood after fatigue protocol. Changes in the baseline value of less than 30% will be considered clinically relevant when compared to values obtained in the control group. Blood samples for analysis of this variable will be performed pre-protocol of fatigue and 24h after protocol of fatigue | — |
