EVENT
Loss of muscle mass (MM) is part of the ageing process [Probably the most significant event for ageing women is menopause, which usually occurs approximately between the ages of 45 and 55 [Therefore, it is not surprising that the World Health Organization recommends that all adults should do muscle-strengthening activities that involve all major muscle groups at moderate or greater intensity and at least twice a week to provide health benefits [Previous studies employing middle-aged and older women primarily made use of machine-based programs or a combination of machine and free weight exercises [However, to increase strength, free weight training might be superior to machine-based programs [Therefore, this is the first study to investigate the effects of free weight RT on muscle strength and body composition in middle-aged women depending on hormonal status (pre- and post-menopausal) and two different intensities. This will include identifying potential differences in the development of fat-free mass (FFM), MM, and strength capacity, as well as FM reduction, according to pre- and post-menopausal status.
