The influences of Mindfulness Meditations (MM) on mindfulness skills in athletes are recent.1,2 Moreover, these studies1,2 proposed long time of MM at a low physical activity intensity level.3 We proposed here to approach new perspectives of reflections on this subject by evaluating the influences of Brief Mindfulness Meditation (BMM) combined with a running program with high intensity on mindfulness skills and well-being in runners. METHODS Fifty-five trained athletes were randomized in a control group or a BMM group following the same running training program. The Mindfulness Inventory for Sport (MIS) was assessed at 3 different times: baseline (T0), 4 (T4) and 8 weeks (T8). It is composed of 3 subscales: (a) awareness; (b) acceptance and (c) refocusing. The Diagnofeel® measured the manifestations and regulations of well-being at T0 and T8. There was 10 subscales: 4 for manifestations (leisure activities, joy, social relations (SR)) and 6 for regulations (AP, isolation, pleasures, taking distance, SR and problem solving). A 2-way repeated measures Analysis of Variance (ANOVA) was conducted for each subscale. A Bonferroni post-hoc test was realized when significant differences were noted. RESULTS No time*group interaction is observed on awareness and acceptance. However, according to refocusing, an increase is discerned only for BMM between T0 andT4 (p = 0.036), T4 andT8 (p = 0.027) and T0 and T8 (p = 0.002). Moreover, inter-group comparisons suggest that BMM group had a better level of refocusing compared to control group only at T8 (p = 0.016). For the well-being, an increase of SR (manifestation) is noted between T0 and T8 for the BMM group only (p = 0.045). Pleasure also increased for BMM group between T0 and T8 (p = 0.042) which had also a greater level of pleasure compared to control group at T8 (p = 0.01). DISCUSSION The most powerful results of this new program are on refocusing. When athletes faced with the intensity of physical effort, they were able to refocus their attention on the present moment and stay engage in the intensity of the effort. From the well-being, the increase of SR and pleasure for the BMM group could also be associated with the ability to refocus in the present moment and to restore their well-being. The implementation of a BMM program seems having an impact on the athlete’s ability to refocus. These benefits also seem to extend beyond a sporting context. More studies with larger sample sizes could be conducted to confirm these results.
