Worked Solution & Example Answer:An athlete was required to complete five vertical jumps in 10 seconds - HSC - SSCE Personal Development and Physical Education - Question 13 - 2001 - Paper 1
Step 1
A) The athlete’s ATP/PC stores have been depleted and there is insufficient recovery time between attempts.
Answer
This statement is consistent with the results. The initial jumps show similar heights, but there is a noticeable decline in performance in the later attempts (3 to 5), which suggests that the short recovery time might have led to depletion of ATP/PC stores.
Step 2
B) The athlete’s glycogen stores have been used up after the second jump, and fatigue has set in.
Answer
While glycogen can affect performance, the decline after jumps 3 to 5 indicates a different metabolic issue, possibly linked more closely to ATP/PC depletion rather than glycogen exhaustion, given the relatively high performance in the first two attempts.
Step 3
C) The athlete’s level of aerobic endurance is low, and this has resulted in oxygen debt.
Answer
This statement does not adequately explain the result. The task is anaerobic in nature and primarily relies on ATP/PC, where oxygen debt is less relevant. The decline is more indicative of anaerobic store depletion than aerobic endurance.
Step 4
D) The athlete’s work at maximum effort has caused lactic acid build-up, and this has reduced performance.
Answer
This statement might partially explain the results, as maximal efforts tend to lead to lactic acid production. However, it is primarily the depletion of ATP/PC stores that is more directly supported by the observed performance decrease.
