January 30, 2017 updated by: Assoc. Prof. Sergej M. Ostojic, MD, PhD, Center for Health, Exercise and Sport Sciences, Serbia

The Effects of Medium-Term Exercise Program on Health-Related Physical Fitness and Biochemical Outcomes in High-Risk Employees

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.
