Abstract: The aim of this study was to compare the relative peak force and rate of force development between the dominant and shin-length feet placed on the starting block in youth swimmers. By using selective sampling, 11 swimmers from the Pathumwan school club at Srinakharinwirot University were selected. The kick start position was shown by participants during the first week of data collection, and their back leg's knee angle was measured. After that, IMTP testing with a similar knee angle was performed. Participants exhibited the kick start posture on the starting block the following week while data collection was taking place, and they also measured the back leg's knee angle. After that, IMTP testing with a similar knee angle was performed. The mean, standard deviation, and comparison of the data were determined using the paired simple T-test and the Wilcoxon signed rank test, with statistical significance set at the 0.05 level. The findings demonstrated that there was no statistically significant difference at 0.05 between the dominant and shin lengths of feet placed on the starting block in terms of relative peak force or rate of force development because the length and knee angle were the same. Although, the results were no different between dominant and shin length, shin length showed slightly higher in relative peak force and rate of force development. Additionally, coaches and sports scientists should continue to emphasize the value of lower-body strength and power and include it in training plans.
