Answer» Answer!!Effects of exercise over respiratory system:-• Increase in tidal VOLUME: With regular exercise, the tidal volume and vital capacity of lungs increase, as chést expands more. • Respiratory muscles become strong: Inner cóstal and diaphragm become strong to work maximally for longer duration. • Expansion of chést: Regular exercise causes greater expansion in chést. This results in the improvement of physical personality. • Increase in number of ALVEOLI: There is an increase in the number of alveoli which purifies more blood. Thus, the efficiency of respiratory system gets improved. • Efficient respiratory system: The efficiency of alveoli increases. This causes more oxygen to reach into the tissues which further causes more production of energy during STRESSFUL conditions (heavy exercise). • Increase in aerobic endurance: Increase in the amount of oxygen in blood decreases the production of lactic acid, therefore, fatigue is DELAYED and hence endurance improves. • Faster removal of carbon dioxide: In a trained person, there is faster removal of carbon dioxide from body. • Improves metabolism: In a trained person, the metabolic reactions are faster for energy production with less consumption of oxygen. • Hydro-balance in body: The water balance in the body is maintained to exercise. Effects of exercise over muscular system:-• Gain in strength: With regular exercise, there is gain in muscular strength and power. • Lactic acid tolerance: Regular exercise increases the ability of muscles to tolerate lactic acid for longer duration. • Efficiency improvement: With regular exercise, there is an increase in the number of capillaries in muscles. By this, there is faster circulation of blood, thus, improving the efficiency of muscles. • Increase in muscle mass: Regular exercise increases the muscle mass. • Proper shape of body: Regular exercise provides proper shaping of body, thus improving physical personality. • Faster recovery from injury: Trained muscles can recover from injury very fast, moreover there are less chances of injuries. • Desired strength can be developed: Systematic and scientific training can develop the desired strength and endurance. • Faster responses: The stimulus travels faster in trained muscles which improves the reflex action. • Efficient use of diet: Trained muscles can efficiently use carbohydrates, proteins, fats, etc as sources of energy with less consumption of oxygen. Effects of exercise over skeletal system:-• More blood supply: Through regular exercises the blood supply in bones improves. • Faster healing: Healing ability of the bones becomes faster. • Increases RBCs: The number of RBCs in the blood increases. • Strong jóints: Sports persons have strong juncture of jóints. Moreover the synovial fluid provides free and easy movement at jóints. • Increases flexibility: The flexibility of the person improves. • Stronger bones: The bones become more strong and slightly stretchable. • Reduces bone injuries: Regular exercise reduces the chances of bone injuries. • Good posture: Good posture is the result of good skeletal system. • Personality development: With regular exercise, the proper growth and development of bones take place. Effects of exercise over circulatory system:-• Hypertrophy of heart: With regular exercise the hypertrophy (enlargement of heart) takes place. • Resting pulse increases: With increased stróke volume, the bàsal heart rate decreases thus, the resting time of heart increases. • Faster adaptation to working load: In trained persons, the heart can adopt to working load quickly. • Return of normal pulse quickly: The pulse RETURNS to normal quickly after exercise. • Increase in haemoglobin: Regular training increases the haemoglobin content in blood. • Faster removal of waste: There is faster removal of waste products from the body. • Reduction in cardiac problems: Regular exercise reduces heart attack risk and other cardiac problems. • Faster healing: The increased circulation of blood makes healing faster. • Blood pressure regulation: A well balanced blood pressure is maintained. |
