- Resistance training
Resistance training has two different, sometimes confused meanings - a more broad meaning that refers to any training that uses a resistance to the force of muscular contraction (better termed
strength training ), and elastic or hydraulic resistance, which refers to a "specific type" of strength training that uses elastic or hydraulic tension to provide this resistance. This article discusses the more limited definition, of "elastic/hydraulic" resistance training.Basic principles
"Resistance training" is a form of
strength training in which each effort is performed against a specific opposingforce generated by resistance (i.e. resistance to being pushed, squeezed, stretched or bent). Exercises are "isotonic" if a body part is moving against the force. Exercises are "isometric" if a body part is holding still against the force. Resistance exercise is used to develop the strength and size ofskeletal muscle s. Properly performed, resistance training can provide significant functional benefits and improvement in overallhealth and well-being.The goal of resistance training, according to the American Sports Medicine Institute (ASMI), is to "gradually and progressively overload the musculoskeletal system so it gets stronger." Research shows that regular resistance training will strengthen and tone muscles and increase
bone mass. Resistance training should not be confused with weightlifting, powerlifting or bodybuilding, which are competitive sports involving different types of strength training with non-elastic forces such as gravity (weight training orplyometrics ) an immovable resistance (isometrics, usually the body's own muscles or a structural feature such as a doorframe). Fullrange of motion is important in resistance training because muscle overload occurs only at the specific joint angles where the muscle is worked.Resistance training can be performed using various types of
exercise equipment or:*Resistance bands

*Swimming machine sTypes of resistance training
Hydraulic resistance
Hydraulic Resistance/Equipment, typically makes it possible for a person to perform strength training as well as cardiovascular training at the same time. Hydraulic resistance can involve exercising in water, where each effort is opposed by the viscosity of the water; or utilizing cylinders/equipment where resistance is a function of speed; the faster the movement, the greater the resistance. Unlike stack weights, gravity neither helps nor hinders the workout. It builds speed
Elastic/resistance band
The elastic resistance band is a portable alternative to weights for
strength training . A variety of exercises have been devised to target specificmuscle groups.ee also
