Brief Summary

Concurrent and aerobic physical exercise are recognized strategies for the treatment of overweight and obesity. The interventions of these modalities have been performed with cardiovascular machines or guided execution in their majority, making it possible to improve the health of this population; however, the studies have used high-cost equipment that is not very accessible to the general population. For this reason, we propose to compare the effects of two 12-week programs: concurrent vs. aerobic, using an innovative methodology with musicalized and outdoor activities, little approached by research. The polarized training intensity distribution model, usually used in sports and now applied to physical activity to improve VO2max, muscular strength, and body composition, will be used to determine which intervention is superior in improving these variables.

Obesity; Concurrent exercise; Combined training; Circuit-Based Exercise; Cardiorespiratory fitness; Muscle Strength; Body Composition

Outcome Measures

Primary Outcomes (1)

• Change in maximal oxygen consumption

  A graded exercise test on a cycle ergometer (ERGO-FIT, Germany) will obtain maximal oxygen consumption (VO2max) using a METAMAX 3B gas analyzer (CORTEX, Germany). VO2max will be reported in ml/kg/min.

  Baseline and 12-weeks

Secondary Outcomes (8)

• Change in mean propulsive velocity

  Baseline and 12-weeks

• Change in maximum velocity

  Baseline and 12-weeks

• Change in peak maximum power

  Baseline and 12-weeks

• Change in body fat

  Baseline and 12-weeks

• Change in muscle mass

  Baseline and 12-weeks

Concurrent exercise

EXPERIMENTAL

Strength component (circuit-based exercise) 7 exercises: * General (2 sets of 15-18 Rep, OMNI-Resistance Exercise Scale 4-5, x 10 s) 180 s * Block (3 sets of 12-15 Rep, OMNI-Resistance Exercise Scale 5-6, x 10 s) 70 s * Concentrated (3 sets of 10-12 Rep, OMNI-Resistance Exercise Scale 7-8, x 15 s) 110 s Aerobic component * Low-to-moderate-intensity continuous training: 16 min to 18 min (\< VT 1) * Interval training: in a block (\> VT 2) * 5 bouts of 30 s loads. Work:rest ratio: 1:1 * 4 bouts of 45 s loads. Work:rest ratio: 1:1 * 5 bouts of 50 s loads. Work:rest ratio: 2:1 * 4 bouts of 60 s loads. Work:rest ratio: 2:1 * 3 bouts of 70 s loads. Work:rest ratio: 2:1 * 4 bouts of 80 s loads. Work:rest ratio: 2:1

Behavioral: Concurrent exercise

Aerobic exercise

ACTIVE COMPARATOR

* Low-to-moderate-intensity continuous training: 36 min (\< VT 1) * Interval training: in two blocks (\> VT 2) 5 bouts of 35 s loads. Work:rest ratio: 1:1 4 bouts of 45 s loads. Work:rest ratio: 1:1 4 bouts of 60 s loads. Work:rest ratio: 2:1 3 bouts of 75 s loads. Work:rest ratio: 2:1 4 bouts of 80 s loads. Work:rest ratio: 2:1
