also called isometric training, evolved in the early 20th century but gained great popularity and support in the mid-1950s as a result of research by several German scientists. These studies indicated that static resistance training caused tremendous strength gains and that those gains exceeded the gains resulting from dynamic-contraction procedures.

Static-Contraction Resistance Training

With free weights, such as barbells and dumbbells, the resistance or weight lifted remains constant throughout the dynamic range of movement. When one is using free weights, the range of motion is less restricted than with machines, and the resistance or weight used to train the muscle is limited by the weakest point in that range of motion

Free Weights Versus Machines

involves varying the resistance to try to match it to the strength curve.

Variable-Resistance Contraction

Another form of dynamic-contraction resistance training, called __________, emphasizes the eccentric phase. With eccentric contractions, the muscle's ability to resist force is considerably greater than with concentric contractions. Subjecting the muscle to this greater training stimulus theoretically produces greater strength gains.

Eccentric Training

With a variable-resistance device, the resistance is decreased at the weakest points in the range of movement and increased at the strongest points. The underlying theory is that the muscle can be more fully trained if it is forced to act at higher constant percentages of its capacity throughout each point in its range of movement.

Variable-Resistance Training

is conducted with equipment that keeps movement speed constant. Whether one applies very light force or an all-out maximal muscle contraction, the speed of movement does not vary.

Isokinetic Training

became popular during the late 1970s and early 1980s primarily for improving jumping ability. Proposed to bridge the gap between speed and strength training, uses the stretch reflex to facilitate the recruitment of motor units. It also stores energy in the elastic and contractile components of muscle during the eccentric contraction (stretch) that can be recovered during the concentric contraction.

Plyometrics

One can stimulate a muscle by passing an electric current directly across it or its motor nerve. This technique clinical setting to reduce the loss of strength and muscle size during periods of immobilization and to restore strength and size during rehabilitation.

Electrical Stimulation

was explored in the rehabilitation setting, specifically for the treatment of low back pain, but its benefits have also been recognized in sport performance. Greater core stability may benefit sporting performance by providing a foundation for greater force production and force transfer to the extremities.
