High-Intensity Intermittent Training Positively Affects Aerobic and Anaerobic Performance in Judo Athletes Independently of Exercise Mode
Question
Do lower-body cycling, upper-body cycling, and judo-specific uchi-komi HIIT modes differentially improve aerobic and anaerobic performance in judo athletes compared with regular judo training alone?
Summary
In 35 male state-level judo athletes, 4 weeks of low-volume all-out intermittent training added to regular judo produced some upper-body aerobic and upper/lower-body anaerobic improvements. The exact adaptations differed by mode: lower-body cycling, upper-body cycling, or judo-specific uchi-komi.
Methodology
- Male state-level judo athletes training regularly.
- 35 participants.
- Cycle ergometer or uchi-komi.
- Work intervals: 20 seconds.
- Recovery: 10 seconds between efforts; 5 minutes between blocks.
- Intensity: All-out.
- 22 minutes 40 seconds including warm-up and rests.
- 2 sessions/week.
- 4 weeks.
- Randomized controlled experimental training study
- Upper-body aerobic power, Wingate power, Blood lactate, and Muscle damage markers were tracked.
Outcomes
Upper-body MAP
Upper-body HIIT increased upper-body maximal aerobic power.
p=0.008 within upper-body group.
Upper-body power
Uchi-komi increased upper-body peak power, and lower-body HIIT increased upper-body power at OBLA.
Uchi-komi PP p=0.015; lower-body POBLA p=0.020.
Lower-body power
Lower-body HIIT improved lower-body mean power in bout 4, while upper-body and uchi-komi groups had lower mean power overall post-training.
Lower-body group bout 4 p=0.007; upper-body p=0.047; uchi-komi p=0.029.
Body composition
Body mass and body fat percentage did not change.
No group, time, or interaction effects, p>0.05.
Insights
- For athletes, a low-volume 20:10 format can be sport-specific or ergometer-based.
- Mode selection matters; adaptations were not identical across upper-body, lower-body, and uchi-komi formats.
- Do not expect body-composition changes from a short low-volume block in trained athletes.
Limitations
- Small all-male athlete groups.
- Control blood markers were not measured.
- No long-term follow-up or competition outcomes.
- Adherence reporting was limited.
Safety
- No adverse events were specifically reported.
- Muscle damage markers increased acutely after Wingate tests but did not show a training-period effect.
- Control-group blood markers were not measured.
