This study aims to compare the effects of pure resistance exercise and resistance exercise added aerobic exercise for enhancing muscle strength of the femoral region and provide the evidentiary materials of an exercise program for improving muscle strength in clinical setting. Muscle activity of rectus femoris showed statistically significant differences after experiment compared to before experiment in the two groups and resistance exercise added aerobic exercise group showed statistically significant difference compared to pure resistance exercise group in group comparison according to the period of measurement. Thickness of rectus femoris showed no significant difference after experiment compared to before experiment in both groups, but resistance exercise added aerobic exercise group showed statistically significant difference after experiment compared to before experiment in group comparison according to the period of measurement. In conclusion, it was found that aerobic exercise after resistance exercise was more effective in enhancing muscle activity and thickness than pure resistance exercise for enhancing muscle activity.

Physical manifestations of aging due to the lack of exercise include the slowing down of motor learning, cardiopulmonary degradation, and the increasing difficulty to adapt to the environment. Aging is manifested with the lack of aerobic exercise work, decrease in muscular endurance, decline in skeletal and muscular strength, flexibility and agility, and the decrease in reaction speed and balance. Added to those are aging-related physiological changes, including the reduction of muscle bulk, increased body fat, decrease in total body water and basic metabolic rate as activities are reduced, and a decrease in cell and Lean Body Mass (LBM). These changes are known to cause problems. Interest and participation in appropriate physical activities among the elderly is needed to help them increase stamina, avoid diseases, maintain a clear intellect, and basically enable the elderly to live their daily lives as easy as possible. Therefore, physical activities are necessary for the elderly to enhance health-related factors. Special exercises should be performed for the enhancement of muscle function, muscle endurance, flexibility, agility, and balance. An accurate measurement of cardio-respiratory endurance and stamina through basic physical and cognitive characteristics of older adults is also required to ensure safety. Also, the development of a more scientific resistance exercise prescription system for the elderly is desperately needed.
