Sample Answer
- The adrenal glands produce adrenaline during physical activity or stress.
- This hormone increases heart rate and blood pressure to deliver more oxygen to muscles.
- As a result, athletes experience improved reaction times and explosive power within seconds.
- Therefore, adrenaline directly enhances movement capacity.
- The adrenal glands also release cortisol during exercise.
- Cortisol increases blood glucose by breaking down stored nutrients for energy.
- Consequently, muscles receive immediate fuel for sustained movement during training or competition.
- This demonstrates how cortisol supports movement by ensuring energy availability.
- Both hormones work together but can conflict during extended exercise.
- While they support initial performance, excessive cortisol breaks down muscle protein.
- Long training sessions with high stress can reduce movement efficiency through muscle damage.
- The significance is that balanced hormone levels prove crucial.
- Timing and amount of these hormones affects overall movement quality.
- Optimal levels enhance performance, but excess or deficiency impairs efficiency.
- Well-trained athletes show better hormone regulation, maintaining performance longer.
- Evidence shows that proper adrenal function proves essential for sustained movement efficiency.
