Effects of Exercise on Muscular System
Hypertrophy
- Increase in Muscle Size.
- Increase in volume of contractile protein within the muscle
- Depends of intensity of effort, volume, training frequency, daily protein intake and inter-set rest
Increase in Tendon Strength
- Tendons are tough bands of connective tissue and like muscle, they increase in strength.
- Tendon biochemistry is typically described in terms of collagen and proteoglycan concentrations.
- Long-term exercise and physical training cause connective tissue remodelling and increased tendon collagen thereby strengthening it.
Increased Number of Mitochondria and Myoglobin
- Myoglobin is a site for storing oxygen in a muscle.
- Mitochondria produces energy as the glucose combines with oxygen to produce ATP.
Increased Muscle Strength
- This is a response to muscles being used more than they are comfortable in ( overload)
- Overloading can be done by increasing resistance.
Increased Tolerance of Lactic Acid
- Efficiency of Clearing Lactic Acid is partly due to capilarisation.
- It allows greater volume of blood to supply into muscles.
