Different HIIT programs performed outside of laboratory has been proposed, especially with body-weight exercises. The high-intensity interval body weight training (HIBWT) is performed without equipment and with low motor skill levels. HIBWT has been shown to improve fat mass, muscle mass, cardiorespiratory capacity and physical performance in young adults with or without overweight. Despite this, no previous studies have evaluated HIBWT efficacy and safe in older people with sarcopenia and cachexia. The study aim was to compare the effectiveness of CT and HIITBW on body composition, metabolic and inflammatory profile, physical function and quality of life in older women with gynecological and breast cancer and their pair-matched controls (older women with no cancer). The hypothesis of the present clinical trial is that HIITBW is effective as well as CT for improvements on body composition, metabolic and inflammatory profile, physical function and quality of life in older women with gynecological and breast cancer.
