Sample Answer
Characteristics: Duration – Intensity – Rest Periods (Any two)
- Long duration (20+ mins) is essential as it allows sufficient time for the aerobic energy system to become the primary energy source, enabling adaptations such as increased stroke volume and improved oxygen delivery to working muscles.
- Moderate intensity (60-75% MHR) enables a steady state of exercise to be maintained without causing early fatigue, allowing the cardiovascular system to efficiently supply oxygen and remove waste products over an extended period.
- No rest periods forces continuous oxygen delivery to working muscles which enhances aerobic adaptations over time, including increased capillarization and improved gas exchange in the lungs.
