Summary of a comparison of mental fatigue and exertion between Olympic-level closed skill atheletes (weightlifters, track & field athletes) and open skill athletes (basketball and volleyball players).
28 elite Olympic weightlifters and track and field athletes (closed skill group; females, males) and 27 elite basketball and volleyball athletes (open skill group; 27 females) during typical training week, 5 months before the Olympics (Australia).
Observational cohort study
- self-reported mental fatigue [VAS score]
- self-reported session’s rating of perceived exertion (sRPE)
- duration of training
- 409 training sessions were analysed
- mental fatigue was significantly higher in open skill athletes (e.g. basketball) than in closed skill athletes (e.g. weightlifting) both for individual sessions and over the week
- sRPE was significantly higher in open skill athletes (e.g. basketball) than in closed skill athletes (e.g. weightlifting) for individual sessions
- mental fatigue was correlated with sRPE only for open skill athletes (e.g., basketball)
- sRPE was correlated with training duration in open skill (small correlation) and closed skill (moderate correlation)
- whole week’s total sRPE was correlated with mental fatigue (moderate correlation) with 125mm-increase in total mental fatigue VAS over a training week icreasing sRPE by 3.75 over a week.
- duration of training had small effect on an individual session’s exertion rating but not on a week’s ratings.
