Objective: This study tested whether text messages prompting adults 50 years of age and older to perform mental imagery would increase aerobic physical activity (APA) duration using a randomized parallel trial design. Method: Participants were assigned to an Imagery 1, Imagery 2, or placebo group. For 4 weeks, each group was exposed to two conditions (morning text message vs. no morning text message). In the morning message condition, the imagery groups received a text message with the instruction to mentally imagine performing an APA, and the placebo group received a placebo message. All participants received an evening text message of “Did you do your cardio today? If yes, what did you do?” for 3 days per week. Results: Participants of the imagery groups reported significantly more weekly minutes of APA in the morning text message condition compared with the no morning message condition. Conclusion: Electronic messages were effective at increasing minutes of APA.

Inactivity is known to have harmful effects on the physical and mental health of older adults. This study used a randomized, parallel trial design to evaluate whether daily text prompts to practice mindfulness would have a positive impact on the time that adults aged 50 years or older spend in aerobic physical activity. The participants were recruited from a certified fitness center and divided into mindfulness and control groups. For 4 weeks, they were exposed to the experimental conditions, with or without the morning text message. In the morning message condition, the mindfulness groups received a text message with the instruction to practice audio-guided mindfulness for 10 min, and the control group received a placebo message. The participants practicing mindfulness reported significantly more weekly minutes of aerobic physical activity and higher intrinsic motivation than the control participants. Mindfulness training was effective at increasing aerobic physical activity duration and might complement physical activity programs.

This study compared the effects of motor imagery, feedback, and feedback+imagery interventions on soccer pass performance in non-elite players (intermediate, regional level). Participants were randomly divided into Control, Feedback, Imagery, and Feedback+Imagery groups, within a pre- post- intervention design. The intervention lasted 7 weeks, and the task consisted of passing the ball to a target 20-meters away. In each intervention session, the participants performed 3 blocks of four physical trials. The participants of the Feedback and Feedback+Imagery groups received expert feedback, given by the coach, after each block and then, all the participants realized a mental task (countdown or motor imagery). Results showed that the Feedback+Imagery group had the greatest pre- to post-test improvement compared to the other groups, and highlight the beneficial effect of combining verbal feedback and motor imagery to improve soccer passing accuracy. It is suggested to coaches or physical education teachers to adapt their training by incorporating feedback and imagery.

The purpose of the present experiment was to examine whether the use of selfhandicapping strategies influences participants’ anxiety levels before athletic performance. Seventy-one competitive basketball players participated in the study. A repeated measures design was used, such that state cognitive and somatic anxiety intensity and direction were measured before and after participants were given the opportunity to self-handicap. Overall, participants reported their cognitive anxiety to be more facilitating after they had the opportunity to self-handicap. Thus, participants who were given the opportunity to self-handicap (i.e., use claimed and behavioral self-handicaps), reported greater increases in perceptions of cognitive anxiety as facilitating their performance. This study shows the importance of looking at anxiety direction, and not just anxiety intensity, when examining self-handicapping’s effects on anxiety. Implications for sport psychologists are proposed.
