Background and Study Aim. Analysis must be conducted so that dive comprehension and learning become more effective and efficient. Speed testing and bi-finswimming movement approach in diving, on the other hand, necessitate specialised equipment. Furthermore, studies on hydrodynamic analysis in diving are still scarce in Indonesia. Thus, the objective of this research was to examine the hydrodynamics of bi-finswimming 4x100 metre bi-finswimming relay athletes.
Material and Methods. The descriptive quantitative research method was employed, along with a survey and a correlational methodology.Document analysis approaches, interviews as problem rationalisation and field tests were used to collect data. Four diving athletes from the National Sports Week competition participated in the study. A dynamometer and a Qualisys underwater camera were among the research tools. Path analysis as a data analysis technique with SPSS application version 23.
Results. According to the survey results, bi-fin swimmers have varied techniques that fall into three categories: effective, less effective, and ineffective. The correlational results revealed that the athlete’s body position to the left is not significant to speed, the athlete’s body position to the right is significant to speed, the athlete’s sliding position with both hands forward is not significant to speed, the athlete’s recovery position with the left hand is significant for speed, and the position of the recovery athlete with the right hand is significant for speed.
Conclusions. Understanding and mastering the bi-finswimming style can reduce drag, resulting in faster speeds. The authors expect that this study will be valuable as a resource for diving coaches and athletes. Future researchers are likely to employ a bigger sample size so that the data acquired can be more broadly generalised.
