Based on the heart rate data shown in the table below, which conclusion is MOST supported by the evidence?

\begin{array}{|l|c|c|c|c|}
\hline \textbf{Training Type} & \textbf{Week 1 RHR} & \textbf{Week 2 RHR} & \textbf{Week 4 RHR} & \textbf{Week 4 RHR} \\
\hline \text{Running} & \text{75 bpm} & \text{72 bpm} & \text{69 bpm} & \text{67 bpm} \\
\hline \text{Cycling} & \text{76 bpm} & \text{73 bpm} & \text{69 bpm} & \text{66 bpm} \\
\hline \text{Swimming} & \text{74 bpm} & \text{73 bpm} & \text{71 bpm} & \text{70 bpm} \\ \hline
\end{array}

  1. Swimming is the most effective activity for reducing resting heart rate
  2. All three training types are equally effective at reducing resting heart rate
  3. Both running and cycling produced significantly better reductions in resting heart rate than swimming
  4. The training program was too short to draw any meaningful conclusions

\(C\)

Show Worked Solution
  • C is correct: Running reduced by 8 bpm, cycling by 10 bpm, both much greater than swimming’s 4 bpm.

Other Options:

  • A is incorrect: Swimming actually showed the smallest reduction in RHR.
  • B is incorrect: The activities clearly show different magnitudes of effect.
  • D is incorrect: Clear trends are visible across the 4-week period, making meaningful conclusions possible.

A student conducted a 4 week training program investigating how different aerobic activities affect resting heart rate. Which of the following is the MOST appropriate method to present the findings?

  1. A single bar graph showing only the final heart rate values for each activity
  2. A detailed written description of heart rate changes without visual aids
  3. A pie chart showing the percentage decrease in resting heart rate for each activity
  4. A line graph showing weekly changes in resting heart rate for each activity across the 4-week period
Show Answers Only

\(D\)

Show Worked Solution

Consider Option D: 

  • D is correct: A line graph shows trends over time, allowing comparison of how activities affected heart rate throughout the intervention.

Other Options:

  • A is incorrect: Shows only final results, omitting important information about progressive changes.
  • B is incorrect: Lacks visual representation, making it difficult to interpret trends and compare activities.
  • C is incorrect: Pie charts are inappropriate for showing changes over time and comparing multiple variables.

Explain how you could use physiological data collected during an aerobic training investigation to draw valid conclusions about the relationship between training intensity and improvement in aerobic capacity.   (4 marks)

Show Answers Only

Sample Answer 

  • Calculate the percentage improvement in aerobic capacity measures (VO₂ max, lactate threshold) for participants training at different intensity zones (low, moderate, high) to determine which intensity produces optimal adaptations.
  • Analyse heart rate data during training sessions to verify that participants maintained their assigned training intensities, ensuring conclusions about intensity-related effects are based on actual training loads experienced.
  • Examine whether a dose-response relationship exists by plotting training intensity against improvements, determining if benefits increase linearly with intensity or if there’s an optimal range beyond which returns diminish.
  • Control for and account for confounding variables such as training volume and frequency when analysing the intensity relationship, ensuring conclusions specifically isolate the effect of intensity rather than other training factors.

Sample Answer 

  • Bar graphs showing average improvements could visually emphasise differences between training methods, but without error bars might exaggerate small differences that aren’t statistically significant.
  • Scatter plots showing individual data points would transparently reveal the distribution of responses in both groups, preventing misinterpretation of averages that might mask substantial overlap between methods.
  • Line graphs tracking changes over time would effectively show the rate of improvement for each method, revealing whether one method produces faster initial gains versus greater long-term improvements.
  • Line graphs tracking changes over time would effectively show the rate of improvement for each method, revealing whether one method produces faster initial gains versus greater long-term improvements.
  • Using percentage change rather than absolute values could alter interpretation by normalising improvements relative to baseline, potentially favoring the method that works better for initially less-fit individuals.
  • Selectively highlighting specific time points or variables where differences are greatest could create bias toward one method, whereas comprehensive data presentation with effect sizes would provide a more balanced interpretation of relative effectiveness.

Sample Answer 

Similarities:

  • Both tables and graphs effectively present heart rate recovery data from aerobic training investigations.
  • Both formats allow comparison of pre- and post-training values across different time periods.

Differences:

  • Tables provide exact numerical values for heart rate measurements, enabling precise analysis of recovery rates.
  • Tables require mental processing to identify trends and patterns in heart rate recovery.
  • Graphs clearly show visual trends in heart rate recovery over time, making patterns immediately visible.
  • Graphs sacrifice numerical precision for visual clarity and may require multiple versions to display comprehensive data.

Explain the extent to which physiological data collected during a 6-week aerobic training study can be used to draw conclusions about long-term responses to aerobic exercise.   (4 marks)

Show Answers Only

Sample Answer 

  • A 6-week study captures initial improvements in heart rate and recovery time but cannot show the complete range of cardiovascular benefits because longer periods are needed for full development.
  • Short-term studies show direction of change but cannot predict whether improvements will continue due to individual variation in response patterns over extended periods.
  • The reason for this is that individual differences in response become more apparent over time which means 6-week studies might not represent the variety of long-term patterns.
  • Early rapid improvements often slow down as a result of the body adjusting to training loads which limits direct long-term predictions.
  • Therefore a 6-week timeframe provides valid information about immediate responses but requires appropriate caution when drawing conclusions about long-term effects.

Analyse how the presentation of data collected during a 12-week aerobic training investigation can influence the conclusions drawn about improvements in cardiovascular efficiency.   (6 marks)

Show Answers Only

Sample Answer 

  • Presenting data as percentage change from baseline rather than raw numbers highlights relative improvements, allowing for more meaningful comparisons between participants with different starting fitness levels.
  • Including both average group results and individual case studies provides a balanced view of overall trends while acknowledging that not all participants respond to aerobic training at the same rate or magnitude.
  • Displaying progressive measurements (at 4, 8, and 12 weeks) rather than just pre/post data reveals the timeline of adaptations, showing whether improvements occur steadily or plateau at certain points.
  • Comparing multiple cardiovascular measurements (resting heart rate, recovery time, blood pressure) creates a comprehensive picture of efficiency improvements rather than relying on a single measure that might not tell the complete story.
  • Using clear visuals like line graphs with consistent scales prevents misinterpretation of the magnitude of improvements, ensuring conclusions accurately reflect the actual physiological changes observed.
  • Separating data by relevant participant characteristics (age groups, initial fitness levels) allows for more precise conclusions about which populations might benefit most from similar aerobic training programs.

Describe TWO methods for presenting findings from a physiological investigation that would effectively communicate the relationship between training intensity and oxygen consumption.   (4 marks)

Show Answers Only

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.
