12 weeks OPT method for enhanching anearobic and aerobic capacity in elite Indonesian female beach volleyball athletes

Introduction: There hasn't been a lot of research done on how the OPT method affects the anaerobic and aerobic capacity of beach volleyball players. Objective: The objective of this study is to investigate the impact of OPT on anaerobic and aerobic capacity among elite female beach volleyball players in Indonesia. Methodology: The research employed a pre-test and post-test format, including six elite female players from the Indonesian National Beach Volleyball Team. An all-inclusive sampling method was utilized with participants N=6, aged between 19 and 27, weighing 52 to 77 kg, standing between 168 and 180 cm tall, and having BMIs ranging from 18.40 to 24.60. The duration of the training program was 12 weeks, consisting of three intensive sessions every week, adding up to a total of 36 sessions. Anaerobic capacity was assessed utilizing the Running-based Anaerobic Sprint Test (RAST), whereas aerobic capacity was evaluated with the Multistage Fitness Test. Analysis of data was performed utilizing SPSS 24 and Microsoft Excel. Results: The findings demonstrated significant improvements in both capacities, with Anaerobic Capacity before at 4.50 ± 0.61 and after at 0.79 ± 0.11, and Aerobic Capacity before at 39.23 ± 1.91 and after at 50.88 ± 0.74. Statistically significant variances were observed (p < 0.05). Conclusions: The research findings indicate a notable rise in anaerobic and aerobic capabilities after completing the OPT training program. It is advised to conduct more research to investigate the wider impacts of the OPT technique on the overall physical abilities of beach volleyball players.
