Final answer:
During a warm-up exercise, five biomechanical processes occur: increased blood flow, increased muscle temperature, increased heart rate, activation of neural pathways, and joint lubrication.
Step-by-step explanation:
The five biomechanical processes that occur during a warm-up exercise are:
- Increased blood flow: Warm-up exercises increase blood flow to the muscles, delivering oxygen and nutrients needed for energy production.
- Increased muscle temperature: Warm-up exercises increase muscle temperature, which improves muscle elasticity and reduces the risk of muscle strains.
- Increased heart rate: Warm-up exercises raise the heart rate, preparing the cardiovascular system for increased activity during the main exercise.
- Activation of neural pathways: Warm-up exercises activate neural pathways, enhancing coordination and reaction time.
- Joint lubrication: Warm-up exercises promote the production of synovial fluid, which lubricates the joints and reduces friction during movement
