| Betaine Exercise Performance Meta-Analysis | While BFR reduces mechanical stress on joints, the associated metabolic stress and discomfort may limit training performance. | 1 | Zhao B (2026) | Combined effects of blood flow restriction training and nutritional intervention on muscle adaptations: a systematic review and meta-analysis. |
| Betaine Exercise Performance Meta-Analysis | Certain nutritional supplements may enhance BFR training effects, but the existing evidence remains inconclusive. | 1 | Zhao B (2026) | Combined effects of blood flow restriction training and nutritional intervention on muscle adaptations: a systematic review and meta-analysis. |
| Betaine Exercise Performance Meta-Analysis | Nutritional interventions were associated with improvements in muscular endurance (SMD = 0.90; 95% CI: 0.55, 1.25; p Conclusion Current evidence suggests that nutritional interventions may support fatigue resistance and enhance muscular endurance under BFR training conditions, but do not provide a clear additional benefit for maximal strength or hypertrophy. | 1 | Zhao B (2026) | Combined effects of blood flow restriction training and nutritional intervention on muscle adaptations: a systematic review and meta-analysis. |
| Betaine Exercise Performance Meta-Analysis | Background Blood flow restriction (BFR) training induces muscle hypertrophy and strength gains under low-load conditions by restricting blood flow. | 1 | Zhao B (2026) | Combined effects of blood flow restriction training and nutritional intervention on muscle adaptations: a systematic review and meta-analysis. |
| Betaine Exercise Performance Meta-Analysis | The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), and study quality was assessed using the Cochrane Risk of Bias Tool. | 1 | Perreras MSL (2025) | Effects of betaine supplementation on endurance exercise performance: a systematic review. |
| Betaine Exercise Performance Meta-Analysis | Of these, two studies demonstrated a significant interaction effect on maximum oxygen consumption and mean power at the latter stage of the Wingate Anaerobic Test, two reported a main effect of treatment on mean power, peak power, and oxygen consumption, and one found significant differences in oxygen consumption and blood lactate levels. | 1 | Perreras MSL (2025) | Effects of betaine supplementation on endurance exercise performance: a systematic review. |
| Betaine Exercise Performance Meta-Analysis | Conclusion These findings highlight the paucity of evidence regarding the ergogenic potential of betaine in endurance exercise performance and underscore the need for additional, more rigorous research to determine its effectiveness. | 1 | Perreras MSL (2025) | Effects of betaine supplementation on endurance exercise performance: a systematic review. |
| Betaine Exercise Performance Meta-Analysis | Purpose Betaine has been studied for its potential ergogenic effects on strength, power, and body composition. | 1 | Perreras MSL (2025) | Effects of betaine supplementation on endurance exercise performance: a systematic review. |
