A student investigated changes in lactate threshold following an 8-week high-intensity interval training program in recreational runners. The results showed an average 9% improvement in the speed at lactate threshold, but no significant change in maximum heart rate.

Identify TWO further research questions that could be explored based on these findings.   (4 marks)

Sample Answer – Any 2 of the following or similar

  • “Would a longer duration training program (e.g., 12 or 16 weeks) continue to improve lactate threshold at the same rate?” directly builds on the findings by exploring the duration aspect of the training program.
  • “How do these improvements in lactate threshold relate to changes in submaximal exercise performance?” connects the physiological measurement to practical outcomes that are observable in Year 11 investigations.
  • “Would different types of high-intensity interval training (varying work-to-rest ratios) produce different improvements in lactate threshold?” examines how modifying the exercise protocol might influence the physiological responses observed.
  • “Is there a correlation between initial fitness levels and the magnitude of improvement in lactate threshold following the training program?” explores individual differences in physiological responses to the same training stimulus.
