Analysis of Flexibility, Strength, and Speed Using Dynamometer and Accelerometer Tests in Swimming Sports

Background and Study Aim. This study aimed to analyze and correlate strength, speed, and flexibility in swimming. The research variables were flexibility, which included (1) maximum right shoulder rotation, (2) maximum left shoulder rotation, and (3) average right and left body roll. The next research variable was Strength, which consisted of (1) maximum strength and (2) average strength. Material and Methods. Participants were elite female and male swimmers with 6 swimmers, aged 18-22 years who were selected through purposive sampling. The participant's criteria were (1) winning a national event, (2) agreeing to follow the test regulations, and (3) being in excellent health. The instruments utilized were a dynamometer and an accelerometer. Data collection techniques included tests and measurements. The data were then examined quantitatively using descriptive analysis techniques and Spearman's rho with Excel and SPSS version 23. Results. The correlation value of 0.943, with a significance level of 0.016 (<0.05), showed a significant relationship between maximal and average left flexibility. The correlation value is 0.943, with a significance level of 0.016 <0.05, demonstrating a significant correlation between average and maximum flexibility of the left shoulder. Furthermore, no substantial correlation exists between other aspects. Conclusions. This is most likely due to the limited sample size, which prevents adequate generalization of the results. of course, the author agrees with the existing theory that there is a correlation between flexibility, strength, and speed. However, further testing is required using the accelerometer and dynamometer tests applied in this research, but with a bigger sample size and stricter athlete control to achieve better results.
