Objective : The PETTLEP (Physical, Environment, Task, Timing, Learning, Emotion and Perspective) is an imagery model to improve
performance in sports. However, there is limited data of the PETTLEP on shooting skills in basketball shooting performance
particularly in Thai basketball players.
Materials and Methods : The present study was a quasi-experimental study; pre- and post-test method. The study was conducted
at Phetchabun Rajabhat University from October to November, 2018. The inclusion criteria were university representative basketball
players (age between 18 and 23 years) who were willing to participate in the study and had no experience on imagery training. Both
pre- and post-test measurement were performed with a mark shooting at 2- and 3-point at the middle of the field for 20 times. The
PETTLEP intervention was conducted for six weeks with regular shooting practice.
Results : There were 24 basketball players participating in the study. Male: female ratio was 1:1. After six weeks of PETTLEP, the free
throw scores were significantly increased from baseline in both 2-point and 3-point regardless of sex. In overall, the average 2-
point free throw increased from 18.83 to 24.00, while the average 3-point free throw increased by 7.96 or 2.65 times of 3-point free
throws.
Conclusion : The 6-week course of PETTLEP plus shooting practice significantly improved the free throw skill in collegiate basketball
players.
