Sleep, training load and performance in elite female gymnasts

Area of Science:

• Sports Science
• Exercise Physiology
• Sleep Science

Background:

• Optimal balance between training load (TL) and recovery is essential for maximizing performance gains in elite athletes.
• Sleep is a critical recovery technique whose relationship with TL and performance requires further investigation.

Purpose of the Study:

• To investigate the relationship between sleep, training load, and performance in elite female artistic gymnasts.
• To analyze how different age categories and competition levels influence sleep patterns and training load.

Main Methods:

• Twenty-six elite female gymnasts across different age categories (U13, U14, Junior, Senior/WC competitors) participated.
• Sleep was monitored using sleep logs, and training load was assessed via session Rate of Perceived Exertion (sRPE).
• Total Sleep Time (TST), Sleep Efficiency (SE), TL, monotony, and strain were calculated; performance was evaluated through rankings.

Main Results:

• TST and SE were lower during weekdays compared to weekends and were highest in the youngest gymnasts.
• Junior gymnasts exhibited the highest TL, monotony, and strain, while U13 and seniors had the lowest TL.
• Higher TL was associated with decreased TST the following night, and reduced TST correlated with poorer performance rankings.

Conclusions:

• Elite gymnasts, especially WC competitors, experience reduced sleep duration and efficiency, particularly before key competitions.
• A negative relationship exists between training load and sleep, with higher loads leading to poorer sleep quality and quantity.
• Strategies focusing on optimizing sleep and managing training load are recommended to enhance performance in elite artistic gymnasts.
