The Ultra-marathon Endurance Study
Efficacy of Lab4 probiotics in the Marathon des Sables
The aim of this study was to investigate the effect of chronic probiotic supplementation before and after an ultra-marathon.
Results showed supplementation with Lab4 probiotics resulted in 12% reduction in runners’ completion time during the ultra-marathon race.
- The completion time in Group 2 (Lab4) was reduced by 5 h and 36 min compared to Group 1 (12% reduction; 2819 min in Group 1 vs. 2481 min in Group 2, Figure 1).
- The completion time with a lower dose of probiotics (Group 3) was reduced by 4 h and 9 min compared to Group 1 (9% reduction; 2819 min in Group 1 vs. 2570 min in Group 3, Figure 2).
