Outcomes

Primary Outcomes

Cardiorespiratory Fitness (CRF)

Time Frame: 8 weeks

CRF will be assessed by measuring maximum oxygen uptake (VO2max)

Muscle strength (only in groups with resistance training)

Time Frame: 8 weeks

Maximum strength (Fmax) of the major muscle groups (chest, upper back, lower back, abdominals and legs) will be estimated through submaximal tests, based on the performance of multiple repetitions.
