Hypothesis

Addition of firm insoles would result in lesser hemolysis compared to soft insoles.

Conclusion

Firm insoles effectively reduce the amount of hemolysis in runners compared to soft insoles during long distance running.

Supporting Evidence

  • Significant hemolysis was observed in participants who ran with soft insoles.
  • Unconjugated bilirubin levels increased significantly post run in runners using soft insoles.
  • Graphical analysis revealed an inverse relationship between insole hardness and hemolysis.

Takeaway

Runners who use firm insoles have less blood damage than those who use soft insoles when running long distances.

Methodology

Twenty male long and middle distance runners were randomly assigned to use either soft or firm insoles during a one-hour run, with blood samples taken before and after to measure hemolysis indicators.

Limitations

The study did not include hard insoles and used a two-group design instead of a repeated measures design.

Participant Demographics

20 male long and middle distance runners, aged 20.4 ± 1.43 years for soft insoles and 21 ± 2.08 years for firm insoles.
