  Purpose
The aim is to come to a consensus about how to prescribe exercise training that actually helps overweight and obese people. Thus, the present study determines the effects of several types of exercise training to define the one with the largest effect with the least effort.

Condition Intervention
Obesity Overweight Behavioral: Strength training Behavioral: continuous moderate-intensity aerobic training Behavioral: high-intensity interval aerobic training

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: Single
Primary Purpose: Treatment
Official Title: Effective Training in Overweight and Obesity

Arms Assigned Interventions
Experimental: strength training
Over a 12-week period, 13 subjects performed three programmed exercise sessions per week; two supervised by the study investigators in the research laboratory and one performed at home or in a gym, according to instructions.
Behavioral: Strength training
a strength training regime of 4 series with 5 repetitions each, at approximately 90% of 1 repetition maximum (RM), in a leg press apparatus to develop maximal strength mainly from neural adaptation with minimal weight gain due to muscular hypertrophy.
Experimental: continuous moderate-intensity aerobic training
Over a 12-week period, 13 subjects performed three programmed exercise sessions per week; two supervised by the study investigators in the research laboratory and one performed at home or in a gym, according to instructions.
Behavioral: continuous moderate-intensity aerobic training
The moderate-intensity group walked continuously for 47 min at 60-70% of maximum heart rate (HRmax) to ensure that the training protocols were isocaloric.
Experimental: high-intensity interval aerobic training
Over a 12-week period, 14 subjects performed three programmed exercise sessions per week; two supervised by the study investigators in the research laboratory and one performed at home or in a gym, according to instructions.
Behavioral: high-intensity interval aerobic training
High-intensity training consisted of a 10 min warm-up period at 50-60% of HRmax [maximal HR (heart rate)], followed by 4×4-min intervals at 85-95% of HRmax with 3 min active breaks in between the intervals, consisting of walking or jogging at 50-60% of HRmax. The exercise session was terminated by a 5 min cool-down period.
