What is Dynamic Tension?
Introduction “Dynamic Tension” is the name Charles Atlas gave to the system of physical exercises that he first popularised in the 1920s. Dynamic Tension is a self-resistance exercise method which pits muscle against muscle. The practitioner tenses the muscles of a given body part and then moves the body part against the tension as if a heavy weight were being lifted. Dynamic Tension exercises…

Fatigue of human muscle
Fatigue of human muscle
As part of her PhD research the very talented and conscientious Anita Beelen collected this data under the direction of Professor Anthony J Sargeant. It was one of the first studies indicating how human muscle fatigue could be due to the selective fatigue of a relatively small population of muscle fibres. Effect of fatigue on maximal power output at different contraction velocities in humansJo…

Types of Muscular Contraction | PT/OT Online
Types of Muscular Contraction
Concentric: is when the muscle shortens while developing tension. Eccentric: is when the muscle lengthens while developing contraction. Isometric: is when tension develops, but there is no change in the length of the muscle. Isotonic: is when the muscle shortens or lengthens while resisting a co...
