Q 33. Explain the methods to improve flexibility with help of examples. 5
Ans: Methods to improve Flexibility
• Ballistic Stretching: The individual performs these stretching exercises while in motion. This
dynamic method used the momentum generated from repeated bouncing movements to stretch
the muscles. Although it is very effective, most experts do not recommend this method because
it may overstretch the muscles and can cause muscle soreness or injury. This method includes
various exercise like swinging the trunk sidewards, forward, backward, swinging the legs etc.
• Static Stretching: It is an extremely popular and effective technique. Static Stretching involves
gently and slowly moving into the stretch position and holding it for a certain period of time.
Movement should take place through the full range of motion until a little tension or tightness
is felt in the muscles or group of muscles. As the muscle relaxes, the stretch should be extended
and held again. Stretching should not be painful. Care must be taken not to force the joint to
move too far, which may cause an injury. Stretching should be held from 10 to 30 second and
a maximum of five repetitions for each exercise, e.g. Seated butterfly stretch.
• Passive stretching: Passive stretching techniques are usually performed with a partner who
applies a stretch to a relaxed joint. Partner stretching requires closer communication between
partners, and the slow application of the stretch in order to 4 prevent injuries due to forceful
manipulation of the body segment, e.g. using a towel, band, gravity or another person to help
you stretch.
• Proprioceptive Neuromuscular Facilitation (PNF) or Contract: PNF technique is the most
appropriate method for increasing or developing flexibility in the shortest possible time. This
method is used by sportsmen for gaining flexibility. It involves use of muscle contraction before
stretching to achieve maximum muscle relaxation.
Q 34. What are the functions of Micronutrients in our diet? Also, mention their deficiency diseases. 5
Ans: Micronutrients are nutrients that are required by the body in lesser amounts for its growth and
development. They play a major role in the metabolic activities of the body. These include vitamins
and minerals. Since our body cannot produce vitamins and minerals, they are taken externally from
different food products. The micronutrient content for every food is different; therefore, it is advisable
to eat varieties of food for enough vitamin and mineral consumption. These micronutrients help in
preventing and fighting certain diseases. However, they should be taken in adequate quantities: excess
intake or inadequate intake results in several disorders such as visual impairment, mental retardation,
etc.

These are required in higher amounts as compared to the trace minerals. The important
microminerals and their functions include:

• Calcium- For the proper structure and function of bones.

• Phosphorus – Cell membrane structure
• Magnesium- Enzyme reactions
• Sodium- Fluid balance and maintenance of blood pressure
• Chloride- Maintains fluid balance and formation of digestive juices.
• Potassium- Nerve impulse transmission and muscle function.
• Sulphur- present in all the living tissues
