Implication

Experimental study reveals HIIT improves energy metabolism and VO2max in competitive swimmers, suggesting training optimization.

Key Points

  • HIIT results in significant improvements in VO2max, enhancing elite swimmers' performance and endurance.
  • Phosphagen energy supply increased significantly from 40.39 kJ to 58.27 kJ, indicating enhanced energy strategies.
  • Lower-limb HIIT program utilized repeated measures analysis to assess interaction effects, ensuring robust data evaluation.
  • Results highlight the effectiveness of HIIT as an essential strategy for optimizing competitive swimming training.
