Training aimed at developing power and strength. Resistance training can use static (isometric) actions, dynamic (ballistic) actions, or both. Dynamic actions include weight-training (with free weights or on a machine, such as a variable resistance device or an isokinetic machine), plyometrics and all other forms of training that involves working against loads greater than normally experienced. Resistance training using weights is usually based on an individual's repetition maximum. Typically, beginners use a weight one half of their l-RM, which they should be able to lift about ten times. Most athletes include resistance training as an important component of their overall training programmes. It is also recognized as important for non-athletes who wish to gain the health-related benefits of exercise. Resistance training can improve the strength and muscle mass of elderly people, reducing the risk of falls, a major source of injury for the elderly. The benefits of resistance training in sport are very specific. When athletes train they should try to use movement patterns and speeds that closely mimic those needed for their particular sport (see principle of specificity).
