The validity of the session-RPE method for quantifying training load in water polo

Area of Science:

• Sports Science
• Exercise Physiology
• Youth Athletics

Background:

• Internal training load (ITL) assessment is crucial for optimizing athletic performance.
• The session rating of perceived exertion (session RPE) method is recognized for its utility in team sports.
• Limited research exists on ITL monitoring using session RPE in youth water polo.

Purpose of the Study:

• To evaluate the effectiveness of the session RPE method for assessing internal training load in youth water polo.
• To determine the reliability of the session RPE method in this specific population.
• To provide coaches with a practical tool for monitoring training load.

Main Methods:

• Thirteen male youth water polo players (age 15.6 ± 0.5 years) were monitored over 8 training sessions.
• Internal training load was assessed using the Edwards summated heart-rate-zone method as a reference.
• Session RPE was recorded using the CR-10 scale, and data were analyzed using Pearson product-moment correlation.

Main Results:

• A high and significant correlation (r = .88, R² = .78, P < .001) was found between the Edwards heart-rate method and session RPE.
• Significant correlations were observed for individual training sessions (r range .69-.92) and player data (r range .76-.98).
• These findings indicate strong agreement between the two methods.

Conclusions:

• The session RPE method is a valid and reliable tool for assessing internal training load in youth water polo.
• This method offers an accessible and efficient way for coaches to monitor training intensity.
• Implementing session RPE can aid in optimizing training plans and preventing overtraining in young athletes.
