The Perceived Recovery Status Scale (PRS) is a valid and reliable tool for monitoring recovery after high-intensity interval training (HIIT-BW). Neuromuscular function and perceptual scales return to baseline within 48-72 hours post-session.
Area of Science:
- Sports Science
- Exercise Physiology
- Rehabilitation
Background:
- Monitoring athlete recovery is crucial for optimizing training and preventing overtraining.
- High-intensity interval training (HIIT) is a popular training modality, but its impact on recovery needs careful assessment.
- Perceptual recovery scales offer a subjective yet valuable method for tracking athlete well-being.
Purpose of the Study:
- To evaluate the validity and reliability of the Perceived Recovery Status Scale (PRS).
- To assess PRS effectiveness in monitoring neuromuscular status post-single bodyweight high-intensity interval training (HIIT-BW).
Main Methods:
- Nineteen physically active men underwent two identical HIIT-BW sessions.
- Countermovement jump (CMJ), PRS, and Numeric Pain Rating Scale (NPRS) were measured at multiple time points.
- Statistical analyses included repeated-measures ANOVA, Spearman correlation, and ICC for reliability and validity.
Main Results:
- CMJ height and impulse showed significant decreases up to 48 hours post-HIIT-BW.
- The PRS demonstrated excellent reliability (ICC: 0.934) and strong correlations with performance and pain measures.
- Neuromuscular performance and perceptual scales returned to baseline between 48 and 72 hours.
Conclusions:
- The Perceived Recovery Status Scale (PRS) is a valid and reliable tool for monitoring recovery.
- Individualized recovery monitoring following HIIT-BW can be enhanced using the PRS.
- Recovery from a single HIIT-BW session is typically complete within 72 hours.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
