Reported findings and study design
Morning recovery heart rate decreased from 83.8 to 74.2 beats/min in the combined arm. Heart rate during full routines and individual elements showed no significant change.
Author-described stratified assignment. Heart rate during training tasks and recovery, with other laboratory and self-reported outcomes.
Dose, route and schedule
One capsule of each oral product twice daily with meals for 20 days. The comparison was usual training without matched placebo.

| Measure | Result | Comparison, timing and statistics |
|---|---|---|
| Morning recovery heart rate | 83.8±1.5 → 74.2±2.5 beats/min | Combination arm, p<0.05 within group. Comparison arm 86.6±3.2 → 88.4±3.6. |
| Evening recovery heart rate | 87.4±2.3 → 77.6±1.7 beats/min | Combination arm, p<0.05 within group. Comparison arm 84.3±3.1 → 83.7±2.4. |
| During routines and individual elements | No statistically significant changes reported | Training heart-rate measures are separate from performance judged in competition. |
