Abstract

Assuming that the forces recorded during the CMJ are related to the muscular leg force and power, the aim of our study is to investigate why in previous studies these recorded forces were not correlated with the forces recorded during the swimming start. A simulated start was recorded on land to try to find if a more similar jumping technique, showed a force related to the swimming start variables. To isolate the start variables in comparison to our previous studies, the swimmer performed only a gliding displacement until 10 m after the water entry without any type of propulsive underwater movements in our present study. We found no difference from the results of previous studies in spite of including simulated grab-start recordings in the lab. Only the horizontal force n the swimming start correlated to five-metre time and the first five-metre mean velocity. The difference and non-relationships when the swimmer applies force against gravity or with gravity have still not resolved.
