This study aimed to investigate alpha power in successful and unsuccessful free throws of elite and novice basketball players.

The current research was quasi-experimental and was implemented in a time series design. Two Elite (10 participants with a mean age of 22.25 ± 1.34) and Novice (10 participants with a mean age of 22.55 ± 1.80) groups participated voluntarily. The data were measured using 28 electrodes from a 32-channel wireless device and were analyzed using the repeated measures analysis of variance test (p≥0.05).

The alpha power of the elite group was higher than the novice group (P=0.001). The successful throws showed lower alpha power than unsuccessful throws (P=0.006). In the comparison of the two groups, the alpha power in the unsuccessful throws of the elite group was higher than in their successful throws (p=0.001), but no difference was observed between the alpha power of the successful and unsuccessful throws of the novice group (p=0.584). The alpha power during the execution time of the free throw task was higher than the pre-execution time (p<0.005), but there was no difference between the first and second pre-execution times (p=1.000). The results of the present study showed that the elite group had higher cortical activity than the novice group in all electrodes (p<0.001).

The findings show that the elite group performed the task with less cortical complexity by inhibiting irrelevant information. In addition, the decrease in alpha power in successful throws indicates an increase in activation of cerebral cortex and an increase in concentration, so that the task can be performed with fewer neural resources.

The aim of this study was to evaluate the effect of PST on performance, retention, and transfer under pressure of novice badminton players. 40 novice badminton players were randomly assigned to experimental (20 participants) and placebo-control (20 participants) groups. In acquisition and retention tests, short and long service, toss clear and drop shots were used; in transfer under pressure test, notational analysis was applied. All participants acquired specific badminton skills in 24 sessions over three months. In addition to specific badminton skills, the experimental group received the specific package of PST during 24 sessions (each session 20 min.) while placebo-control group received the same number of sessions about general information on badminton. The results of mixed ANOVA indicated that in all tests, the scores of experimental group were significantly higher than those of the placebo-control group, which indicated the effectiveness of PST on performance and learning of novice male badminton players. The results of this study extended the effectiveness of PST to learning new motor skills.

The purpose of this study was to evaluate the effectiveness of psychological skills training program on developing mental toughness among novice badminton players. Based on entrance criterias, 40 male novice badminton players were randomly assigned to experimental (20 participants) and placebo-control (20 participants) groups. Before and after interventions, participants completed sport mental toughness questionnaire (SMTQ). All participants take part in specific skills training badminton during 24 sessions over three months. Experimental group in addition to badminton learning received the specific package of psychological skills training but Placebo-control group was taught only general information about badminton. The results of MANCOVA showed that all components of SMTQ in experimental group were significantly higher than the placebo-control group, which indicates the effectiveness of PST on mental toughness development among male badminton novice players. These results supported the capability of developing mental toughness through systematical psychological skills training programs.
