PHYSIOLOGICAL FACTORS DETERMINING STRENGTH
physiological factors, determine strength / fit - iland
Strength is ability to resist or overcome resistance. It is of three types : Maximal, Explosive, Strengih endurance :
physiological factors, determine strength / fit - iland
- Muscle Covering : The muscle fibres covering sarcolemma' binds the muscle fibres to work together. The sarcolemma covering increases the muscle cross-sectional area and helps in strength component.
- White Muscle Fibre : White muscle fibres (fast twitch muscle fibers) have more connective tissues and they bring fast and strong contractions. Greater the percentage of white muscle fibres helps in explosive strength.
- Muscular Contraction : Muscular contraction is of two types : Concentric and Eccentric, It regulates our muscular action in controlled manner. It helps in accuracy and efficiency of movement, thus helpful in strength development.
- Muscle Length : Every muscle is of different size. Long muscles have more potential of strength as compared to small muscles.
- Neuromuscular Responses : The neuromuscular responses are the impulses produced by nervous system to control muscular contractions. The intensity of neuromuscular responses (impulses) determine strength.
- Adequate Energy : The muscular movements need sufficient energy. Greater number of mitochondria in muscle fibres produces more energy and stronger and longer muscular contraction.
- Age : Strength of muscles is maximum between 20 to 40 years of age and it gradually weakens.
- Gender : Men have more strength as compared to women due to bigger and longer muscle length in males.
