The related proportion of fast twitch fribwr and slow twitch fiber determine the maximum possible speed with which the muscle is contract • flexibility- flexibility also determine the speed . I’m fact good flexibility allows maximum range of movements • biochemical reserve and matabolic power- muscle reyuirrd more amount of energy and high rate of consumption for maximum speed performance .

Kon kon 2024 2025 batch ka h ..
Flexibility..is also determine the speed
....in fact flexibility is good it also...maximum range of movement
5:37 Intensity of nerve impulse : a muscle has several motor units .the force apply on muscle depends upon no. Of contracting motor units . .but when astronger nerve impulse is sent from central nervous syten it will produce more strength

Muscle composition...each muscle contain two types of fibres
...fast twitch white fibres
Or slow twitch fibres...
The percentage of fast twitch or low twitch fiber...are genetically determined and cannot be changed through the training...
If the percentage of fast twitch fibres is more they produce large amount of strength
💪💪
Abrasion
Abrasion injuries most commonly occur due to moving,
Factors of determining speed - •muscle composition - white finer plays a major role in muscle contraction with more speed and its cannot change with training ( the amount of fiver are genetically ) different muscle of body having different % of white fiber
• explosive. Strength - it’s depend on the size, shape and coordination of the muscle . For very quick and explosive movement , explosive strength is required . The related proportion of fast twitch fribwr and slow twitch fiber determine the maximum possible speed with which the muscle is contract
• flexibility- flexibility also determine the speed . I’m fact good flexibility allows maximum range of movements
• biochemical reserve and matabolic power- muscle reyuirrd more amount of energy and high rate of consumption for maximum speed performance . For this purpose the store of atp and cp in the muscle Should be enough. If the store is less then the working process of the muscle slows down after short time

Effects of exercise on muscular system :
Change in size & shape of muscle
Correct body posture
Food storage increases
Toned muscles
Efficient movement of muscles
Change in connective tissues
Effects of exercise on Cardio Respiratory system :
Decrease in resting heart rate
Increase in size of heart
Stroke volume increases at rest
Increase in cardiac output
Increased blood flow
Decrease in blood pressure
Increase in blood volume
Physiological factors to determine strength are as follows :
1. Size of muscles
2. Body weight
3. Neural signals
4. Muscle composition
Strength depend on the size of muscle...if the size of muscle is larger it produced more force...size of muscle can be increased by doing various exercises...
