1. Immediate and Long term effects
Immediate Effects of Exercise
Long Term Effects of Exercise
1. Immediate and Long term effects
Immediate Effects of Exercise
Long Term Effects of Exercise (regular training)
Build up of lactic acid (cramp)
Can you explain why?
Muscle hypertrophy (increase muscle mass) can lead to:Increase in strength
Increase endurance
Increase power
Improved posture
1. Immediate and Long term effects
Immediate Effects of Exercise
Long Term Effects of Exercise (regular training)
Build up of lactic acid (cramp)When aerobic respiration is know longer possible due to high demand of Oxygen; Anaerobic respiration must occur to produce energy. One waste product is LA.
Muscle hypertrophy (increase muscle mass) can lead to:Increase in strength

Increase power
Improved posture
