Question 49

Positive Short-term impacts of physical activity (3) (muscular system)

Answer 49

- increased blood flow - increase in muscle temperature - increase alertness

Question 50

Negative short-term effects of physical activity (3) (muscular system)

Answer 50

- increased chance of muscle soreness - can be left fatigued - depleted energy and myoglobin stores
