- The aim of this study was to examine the extent to which a mindfulness-based program could reduce the number of sports injuries in a sample of soccer players. A total of 41 junior elite soccer players were randomly assigned to the treatment or the attentional control group. The treatment group took part in a 7-session program based on the mindfulness, acceptance, and commitment (MAC) approach (Gardner & Moore, 2007). The attentional control group was offered 7 sessions of sport psychology presentations with a particular focus on soccer. There were no statistically significant differences in injury rates between the two groups (U (39) = 149.50, z= −1.77, p = .077), but there was a medium effect size (adjusted Cohen´s d = −0.59, approx. 80% CI for d = −0.37 – −0.74). Moreover, 67% of the players in the mindfulness group remained injury-free in comparison to 40% in the control group. This result suggests that an intervention program focusing on strategies for improving attention could decrease injury risk. Recommendations include applying mindfulness exercises in athletes’ daily training to help lower injury risk. © 2015, Copyright © Association for Applied Sport Psychology.

- Null hypothesis significance testing (NHST) is like an immortal horse that some researchers have been trying to beat to death for over 50 years but without any success. In this article we discuss the flaws in NHST, the historical background in relation to both Fisher's and Neyman and Pearson's statistical ideas, the common misunderstandings of what p < .05 actually means, and the 2010 APA publication manual's clear, but most often ignored, instructions to report effect sizes and to interpret what they all mean in the real world. In addition, we discuss how Bayesian statistics can be used to overcome some of the problems with NHST. We then analyze quantitative articles published over the past three years (2012-2014) in two top-rated sport and exercise psychology journals to determine whether we have learned what we should have learned decades ago about our use and meaningful interpretations of statistics.
