Design outcomes
Primary
| Measure | Time frame |
|---|---|
| expected outcomes Positive changes in isometric and isotonic muscle strength levels in trained groups mainly for the eccentric group. Maintaining the flexibility, pain, feeling exertion, blood pressure, heart rate and its variability values for both training groups. Presence of negative changes to the stress groups considering flexibility, pain, feeling exertion, blood pressure, heart rate and its variability. Presence of increase in blood markers of stress in groups and eccentric training(CK, TNF-alpha and cortisol). ;Outcomes Found: Gain of strength in eccentric exercise compared to their control. Best power for the training groups. Increased sensitivity and pain in the control groups in relation to training. Higher concentrations of Ck in the control group compared to concentric training. HR recovery between 1 and 3 minutes after exercise in any type of contraction. | — |
Secondary
| Measure | Time frame |
|---|---|
| expected outcomes Greater benefit - cost difference in favor to the training groups compared to those not trained. Equivalent benefit - cost difference comparing trained groups. Greater difference benefit - cost in favor to the untrained concentric group compared to the excentric group. ;outcomes found Greater benefit - cost in favor to the eccentric trained group relative to its control. Greater number of positive responses in eccentric training group compared with other groups considering all variables | — |
