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.
