Exploring self-talk mechanisms: Heart rate variability during exercise
The purpose of the present study was to examine whether self-regulated calming self-talk cues may affect autonomic nervous system functioning during moderate intensity aerobic exercise. An experimental design was adopted and heart rate variability was monitored during exercise to to assess changes in the functioning of the sympathetic and the parasympathetic system. Participants were 83 healthy, physically active, non-smoking sport science students (males=47, females=36) with a mean age of 21.02 (± 2.31), who were randomly assigned to experimental (n=44) and control (n=39) groups. Participants cycled at 50% of heart rate reserve for 20 minutes with the experimental group using self-talk following respective instructions. Heart rate variability was recorded during the whole procedure (Polar V800). Heart rate variability measures were averaged to 4min intervals and analyzed using repeated measures analysis of variance. The analysis showed non-significant multivariate effects; however, univariate analyses showed significant group by time interactions for RMSSD, HF, LF/HF ratio, and Poincare SD1, during the final 8min of exercising (p < .05). These differences reflected greater vagal activation for the experimental group, compared to the control group. The differences observed in the vagal direction may be explained through the calming effects self-talk may have had during exercise, and in particular during the later parts, suggesting a more composed or effortless performance. The present findings should be cautiously interpreted; however, they provide encouraging evidence to further investigate psychophysiological measures for the understating of self-talk effectiveness.

The relationships between achievement goals, empowering and disempowering climate, and female athletes' self-talk in football.
The present study examined the relationships between athletes’ use of self-talk, achievement goals, and motivational climate. Participants consisted of one hundred ninety one female football players from Greece, aged from 10 to 23 (M=16, SD= 2.12). The athletes completed a short version of the Automatic Self-talk Questionnaire for Sport (ASTQS) for self-talk, the Empowering and Disempowering Motivational Climate (EDMCQ-C) for motivational climate, and the Task and Ego Orientation in Sport Questionnaire (TEOSQ) for achievement goals. Two hierarchical regression analyses were conducted in order to examine the degree to which goal orientations (i.e., task and ego orientation) and perceptions of coach-created motivational climate (i.e., perceived empowering and disempowering climate) could predict players’ positive and negative self-talk. The findings revealed with regard to positive self-talk that achievement goals explained 5% of the variance. In particular, task orientation emerged as the only significant predictor of players’ positive self-talk. The addition of the empowering and disempowering climate at Step 2 increased significantly the total explained variance to 6%. With regard to negative self-talk, the findings revealed that at Step 1 achievement goals explained 4 % of the variance. Ego orientation was the only significant predictor of players’ negative self-talk. At Step 2 the total explained variance increased to 11% showing that only disempowering climate significantly and positively predicted players’ negative self-talk The results are discussed in relation to the important role of coaches’ behaviour in the formulation of athletes’ self-talk.
