Sample Answer – Any 2 of the following
- A scatter plot with a line of best fit would effectively present the relationship between training intensity (x-axis) and oxygen consumption (y-axis), visually demonstrating the correlation and allowing for identification of the aerobic threshold where oxygen consumption increases disproportionately to intensity.
- Tables organising data by intensity zones (low, moderate, high) with corresponding average oxygen consumption values would allow for clear numerical comparison across intensity levels and could include standard deviations to show variability within each intensity zone.
- Line graphs showing oxygen consumption over time at different intensity levels could effectively display how oxygen uptake kinetics change based on exercise intensity, particularly highlighting differences in steady-state achievement and oxygen deficit at different intensities.
- Heat maps could represent individual participant responses across various intensity levels, effectively visualising both group trends and individual variations in oxygen consumption responses to increasing training loads.
