The Effect of Short-Term Wingate-Based High Intensity Interval Training on Anaerobic Power and Isokinetic Muscle Function in Adolescent Badminton Players

Ko DH, Choi YC, Lee DS

Question

Does 4 weeks of Wingate-based cycling HIIT improve anaerobic power and isokinetic knee muscle function in adolescent badminton players compared with moderate continuous training?

Summary

In male adolescent badminton players, 4 weeks of Wingate-based cycling HIIT improved body fat, repeated anaerobic power/fatigue resistance, and high-speed isokinetic knee muscle endurance more than moderate continuous resistance/endurance training. Heart-rate recovery after Wingate testing did not change.

Methodology

  • Male middle-school and high-school badminton players.
  • 32 participants.
  • Stationary bicycle sprint intervals.
  • Work intervals: 30 seconds.
  • Recovery: 150 seconds active recovery at 50% HRmax.
  • Intensity: 90% HRmax or higher during work bouts; pedal as quickly as possible at a given load.
  • 30 minutes total exercise period with 5-10 minute warm-up and cool-down.
  • 3 sessions per week.
  • 4 weeks.
  • Randomized controlled pre/post training study.
  • Body composition, Repeated anaerobic power, Heart-rate recovery, and Isokinetic knee function were tracked.

Outcomes

Body fat

Body fat and body fat percentage decreased significantly in the HIIT group, not MCT.

Abstract reports HIIT body fat decrease p = 0.019; between-group decrease reported significant.

Improved

Anaerobic power

Both groups improved early Wingate sets, but HIIT maintained significant peak-power gains into later repeated sets.

Between-group differences significant in set 3 p = 0.019 and set 4 p = 0.021.

Improved

Fatigue index

HIIT improved fatigue resistance more than MCT in later Wingate sets.

Between-group differences in sets 3-5: p = 0.032, p = 0.017, p = 0.003.

Improved

Heart-rate recovery

Heart-rate change after the anaerobic power test did not significantly change in either group.

No statistical change in either group.

No clear change

Isokinetic function

Both groups improved low-speed knee strength; only HIIT significantly improved high-speed muscle endurance.

HIIT high-speed 240°/s improvement reported p = 0.035.

Mixed

Insights

  • Repeated 30-second cycling HIIT may build repeated-sprint fatigue resistance in adolescent court-sport athletes.
  • Four weeks may be enough for performance changes, but not heart-rate recovery changes.
  • The protocol is athlete-specific and equipment-based, with limited direct translation to general home workouts.

Limitations

  • Small male-only athlete sample.
  • Age groups were not separately analyzed.
  • Food intake and daily activities were not controlled.
  • Only one HIIT and one comparator type were tested.
  • Short intervention and no follow-up.

Safety

  • Currently injured athletes were excluded.
  • Final participants reported no chronic back, knee, or ankle pain and no problems with running, jumping, or cutting.
  • Athletes and staff checked program availability and safety.
  • No adverse events or injuries during training were reported.
