| Effect on peak power (%) | Inference | ||
|---|---|---|---|
| Mean | ±90 % CL | ||
| Effect on treatment groupsa | |||
| Males | 1.8 | ±5.0 | Unclear |
| Controls | 4.5 | ±3.8 | Possibly moderate ↑ |
| Modifying effects | |||
| Fivefold increase in work/rest ratio | 5.7 | ±3.5 | Possibly moderate ↑ |
| Threefold increase in sessions | 2.9 | ±3.5 | Likely small ↑ |
| Females | 2.0 | ±6.3 | Unclear |
| Baseline peak power lower by 5 W/kg | 1.6 | ±3.2 | Unclear |
| Uncontrolled study | −1.0 | ±3.7 | Unclear |
Effects on treatment groups are presented as intervention minus control
Reference training: a controlled study of 12 low-volume HIT sessions with a work/rest ratio of 0.10
CL confidence limit, HIT low-volume high-intensity interval training, ↑ indicates increase
aMales, with baseline peak power output adjusted to 11.5 W/kg
