Two athletes took part in different training programmes. One undertook regular training sessions while the other undertook high intensity interval training (HIIT) sessions. The graph shows the time taken to complete a run before and after each training programme. The improvement in performance as a result of HIIT training compared to regular training is A 30s B 40s C 50s D 80s

Answer

To determine the improvement in performance due to HIIT training, we first need to analyze the graph. Looking at the bar representing the time taken before HIIT training for the athlete, it appears to be around 780 seconds. After HIIT training, the time taken is approximately 750 seconds.

Next, we calculate the improvement:

$ext{Improvement} = ext{Time before HIIT} - ext{Time after HIIT} = 780 ext{s} - 750 ext{s} = 30 ext{s}$

Thus, the answer is A 30s.
