Effect of Hydrogen-rich Water During Tapering on Recovery After Functional Overreaching in Basketball Players

Condition(s) studied

Investigational drug(s) / intervention(s)

Hydrogen-rich water: Hydrogen-rich water with molecular hydrogen concentration \>1.0 ppm.

Placebo water: Tap water without molecular hydrogen.

Study summary

The goal of this clinical trial is to evaluate whether hydrogen-rich water supplementation during tapering improves recovery after functional overreaching in competitive male basketball players aged 18-35 years. The main questions it aims to answer are:

* Does hydrogen-rich water improve autonomic recovery after functional overreaching?
* Does hydrogen-rich water improve recovery in biochemical, performance, and subjective feeling outcomes during tapering?

Researchers will compare hydrogen-rich water to placebo (water containing no molecular hydrogen) to determine whether molecular hydrogen improves recovery after accumulated fatigue has been induced by functional overreaching. Participants will:

* Complete a training cycle including normal training, functional overreaching, and tapering.
* Consume hydrogen-rich or placebo water daily during the one-week tapering period.
* Undergo repeated testing of autonomic nervous system, blood biochemical markers, performance, and subjective soreness.

Eligibility

Primary outcome measure(s)

• RMSSD — One-week change between post-overreaching and post-taper.
  The root mean square of successive differences of RR intervals (RMSSD) is used as an index of parasympathetic activity and is calculated from an ECG using heart rate variability analysis.
