High-intensity interval training program for HIT and SIT groups.
Table 3.
Anthropometric, physiological and performance results (mean ± SD) of HIT and SIT groups before and after six weeks of training.
Fig 2.
Simulation performance before (PRE) and after (POST) 6 weeks of HIT or SIT.
*p<0.001 versus pre-training (main effect for time). Lines denote individual data for 7 subjects in the HIT group and 9 subjects in the SIT group. HIT—high-intensity aerobic interval training; SIT—sprint interval training.
Fig 3.
Forrest plot of percentage changes (ANCOVA) with 95% confidence intervals between HIT and SIT.
The vertical zero-line represents SIT. BM—body mass; PPO—peak power output; LT—lactate threshold; OBLA—onset of blood lactate accumulation; HIT—high-intensity aerobic interval training; SIT—sprint interval training; Δ %—percentage change.

Effect size and magnitude-based inference for anthropometric, physiological and performance results of HIT and SIT groups after six weeks of training.
Fig 4.
Average weekly training loads of HIT and SIT groups.
Calculated using the session rating of perceived exertion (RPE) method, i.e., multiplying the cyclist RPE (using the Category Ratio Scale; CR100) referring to the whole training session by session duration in minutes. HIT—high-intensity aerobic interval training; SIT—sprint interval training; a.u.—arbitrary units.
