Furthermore, mean and standard deviation were calculated as initial data for further analysis on the normality (Chi-square method), homogeneity (Levene&#39;s test method), and bivariate correlation test with sig <0.01. The PowerLine instrumentation system introduced by Peachinnovation was synchronized with 3 Panasonic Handycam HC-V100 Full HD cameras for video recording purposes.<br> <strong>Results. </strong>The results showed that the p-value of the catch angle against the effective angle is 0.566, and the p-value of the finish angle against the finish angle is -0.761, indicating the presence of variations in the magnitude of force generated by four rowers with the same force graph shape. The study offered a thorough scientific examination of oarlock force concerning the angle and timing of rowing in the boat. This clarification enhanced the understanding of previous examinations on the force&#39;s effectiveness concerning rowing angle and time. A total of 4 observed rowers were synchronized, and the results showed variations in force magnitudes concerning time and angle while the graph shape remained constant.<br> <strong>Conclusion. </strong>The rowing method of the four athletes was harmonious, but the collective effectiveness was not uniform.</div> Rowing, Powerline, Elite Rower 0 0 http://aassjournal.com/browse.php?a_code=A-11-1997-4&slc_lang=en&sid=1 Dede Rohmat Nurjaya Dede-rohmat-n@upi.edu 100319475328460016758 100319475328460016758 Yes Sports Coaching Education Program, Faculty of Sports and Health Education, Universitas Pendidikan Indonesia, Bandung, Indonesia Agus Rusdiana agus.rusdiana@upi.edu 100319475328460016759 100319475328460016759 No Sports Science Program, Faculty of Sports and Health Education, Universitas Pendidikan Indonesia, Bandung, Indonesia Angga M.
