Maximal Muscular Strength as a Predictor of Optimum Drop Height

Milan Matic

The first goal of the study was to examine the relationship between maximum muscle strength and optimal drop height (DH opt ), while the second goal was to examine the relationship between regression models for the prediction of DH opt and DH opt determined by variable H. A total of 30 respondents, students of the Faculty of Sport and Physical Education participated in the experiment. During the experiment, eight altitudes were randomized in the range of 0.12 to 0.82 m. The instruction was to achieve a higher jump, with a shorter duration of rebound. A positive statistically significant correlation between DH opt determined by the prediction method with 1 RM / BM 0.67 and MDS (p<0.05) was calculated. When computing the DH opt connection determined by the dialing method with the maximum muscle strength of the participants, no statistically significant correlation was obtained, but there is a positive trend. Determined by the prediction method DH opt is (0.47±0.17 m) and using the regression model with 1 RM/BM 0.67 it is (0.47±0.07 m) and with MDS (0.48±0.06 m). In order to explain the high relationship between the models, it should be noted that the muscles of the knee joint have a more important role in motor tasks performed at higher intensity like during the drop jump. With this in mind, DH opt in the jump can be determined depending on the neuromuscular capacity to generate the maximum muscle strength of the knee in order to use the optimal intensity within plyometric training.
