There is a high incidence of overweight or obesity in middle-aged Korean women. In addition, the potential health benefits related to muscle strengthening physical activity (MSPA) in the management of overweight or obesity have been reported. As such, there has been a growing number of studies to investigate the effects of MSPA alone or MSPA combined with aerobic PA (APA) i.e. combined PA (CPA) in overweight or obese middle-aged Korean women. Information about the effectiveness of these types of PA and the amounts required to attain substantial target health benefits will be valuable as this information helps provide more effective and feasible PA recommendations by providing a better and/or alternative forms of PA with the minimum PA amount. As such, the author analyzed the results of MSPA and CPA training programs applied to overweight or obese middle-aged Korean women. Though the muscle mass increasing effect was supported only in a small number of studies, significant target health benefits including the effects related to obesity related indices, cardiorespiratory fitness, and some other cardiometabolic risk related parameters were supported in the majority of studies. Therefore, it is implied that not alone APA but also MSPA and CPA could be provided as effective forms of PA. However, with a limited number of studies, especially with little randomized controlled trials, further research is required to generalize the findings. In addition, further research with various amounts of PA is required to gain a greater understanding of the minimum MSPA & CPA amounts for target health benefits.
