Brief summary

The purpose of this study is to investigate the effects of three different exercise programs (e.g. low-intensity, medium-intensity, high-intensity) administered for six months on health-related physical fitness, biochemical variables and general health outcomes in high-risk employees, with about 2000 volunteers will participate in the randomized and repeated-measure study.

Detailed description

Exercise programs (e.g. low-intensity, medium-intensity, high-intensity) consist of aerobic workout, strength training and flexibility exercise, with different program has different intensity, volume, frequency and duration of exercise.

Interventions

PROCEDUREExercise 1

Low-intensity, low-volume cardiorespiratory exercise and strength training

PROCEDUREExercise 2
