Sample Answer
Overview Statement
- Investigating environmental effects on body temperature during aerobic training involves comparing indoor versus outdoor exercise conditions.
- These conditions differ in heat exposure and how hard the body works to control temperature.
Condition 1: Indoor Training Environment
- Students perform aerobic exercises in a controlled indoor space with steady temperature and no extra heat sources.
- This enables stable conditions that reduce outside temperature factors affecting body temperature changes.
- The relationship between controlled conditions and measurement accuracy means more reliable temperature data collection.
- This approach results in easier digital thermometer readings without weather problems or extra heat stress.
Condition 2: Outdoor Training Environment
- Students perform identical aerobic exercises outdoors on a warm day with direct sun exposure.
- This creates extra environmental heat stress that influences how the body controls temperature during exercise.
- The interaction between outside heat and internal exercise heat leads to higher body temperature readings.
- However, this generates extra factors like wind and humidity that affect how the body cools itself.
Implications
- The significance is that comparing both environments reveals how outside conditions impact body temperature responses.
- Therefore this method enables students to understand environmental effects using simple digital thermometer equipment.
