Question
Explain any three physiological factors determining strength.
✓
Answer
The various physiological factors which determine the strength of an individual are stated below:
- Size of the Muecle: The strength of the muscle largely depends upon the size of the muscle. It is a well known fact that bigger and larger muscles can produce more force. The force produced by the same size of muscle in males and females is approximately same but males are found to be stronger because they 'have larger and bigger muscles in comparison to females. With the help of different methods of strength training such as weight training, the size of the muscle can be increased and thereby strength is improved. So, the strength is determined by the size of the muscle.
- Body Weight: It is also a well known fact that the individuals who are heavier are generally stronger than the individuals who are lighter. There is a positive correlation between body weight and strength among international weightlifters. The heavier weightlifters lift heavier weights. So, body weight also determines the strength of an individual.
- Muscle Composition: Each muscle consists of basically two types of muscle fibres, i.e., fast twitch fibres (white fibres) and slow twitch fibres (red fibres). The fast twitch fibres are capable to contract faster and therefore they can produce more force. On the contrary, the slow twitch fibres are not capable of contracting faster although they are capable of contracting for a longer duration. The muscles which have more percentage of fast twitch fibres can produce more strength. The percentage of fast twitch fibres and slow twitch fibres is genetically determined and cannot be changed through training. So, it can be said that the percentage of these fibres determines the strength of a person.
