Maintaining strength and muscle mass is vital for healthy aging because muscular strength and endurance tend to decline with age. This loss can be delayed and strength can be maintained by participating in a strength program. Many people have joined health clubs and are enjoying the benefits of using weight equipment such as Universal, Nautilus, and Cybex. The result is a better physical appearance and greater efficiency in both everyday activities and sudden emergencies. It is characterized by activities of long duration but low intensity.
Muscular endurance is important for good posture and for injury prevention.
For example, if abdominal and back muscles are not strong enough to hold the spine correctly, the chances of lower-back pain and back injury are increased. Muscular endurance helps people cope with the physical demands of everyday life and enhances performance in sports and work. It is also important for most leisure and fitness activities. The degree to which strength or endurance develops depends on the type and amount of stress that is applied. Strength and endurance are essential in everyday activities such as housework, yard work, and recreational sports.
