Worked Solution & Example Answer:An athlete’s body is using the lactic acid energy system - HSC - SSCE Personal Development and Physical Education - Question 1 - 2022 - Paper 1
Step 1
What is the likely duration of their performance while using this system?
Answer
The lactic acid energy system, also known as anaerobic glycolysis, typically fuels performance for a duration of about 30 seconds to 2 minutes. This energy system is predominantly used during high-intensity activities that last longer than about 10-15 seconds but less than 2 minutes. Thus, the most appropriate answer from the given options is B. 60 seconds.
