Health Related Physical Fitness is called slow twitch fibre (red). Both the fibres are present in the muscles. The quality of the muscle depends upon the proportion of the fibres in the particular muscle. If the fast twitch fibres are more in ratio, then the muscle will contract faster and generate more force.
This type of muscle has anaerobic capacity. Whereas, the muscle having slow twitch fibre will generate less force in comparison to the muscle with fast twitch fibres. . Energy supply: Muscles get their energy by the breakdown of ATP (Adenosine Triphosphate) and CP (Creatine Phosphate) which is stored in the body.
The amount of ATP and CP store is very essential for the muscular activities as it provides the energy to the muscles. . Psychological factors: In many of the situations, the psychological factors contribute a lot in getting more forceful muscular contraction. The factors such as anger, aggression, motivation, etc., play a very crucial role in pushing their mind to develop very strong nerve impulse which can lead to activate more number of motor units.
Methods of Strength Improvement Strength is regarded as a very essential part of sports performance. It is a conditional ability and can be improved to a greater extent by the training. There are various methods by which one can achieve the level of strength one wants. Whenever we think about improving the strength ability of an individual, the first thing which comes to our mind is the structure of our activity where we are going to use this strength.
In some of the activities, our own body weight acts as a resistance and in some cases, external resistance plays the maximum role. For example, in cross country races while running on the hill, our own body weight acts as a resistance and in weight lifting, external weight acts as the resistance. So, when we design resistance training for developing strength ability of an individual, we keep both the conditions in our mind. We know that countering the resistance again and again will help us to improve our strength ability.
For improving the strength ability, the following methods are used. Activity . Perform push-ups, pull-ups, sit- ups along with your classmates and find who scores highest in these activities. -
