Abstract

The objective of this study was to analyze the differences between heights or potencies produced in a jump test using different percentages of a Maximum Repetition (1MR), as well as identifying weight zones where the high potencies and those where it is not possible to jump are reached. Materials and Methods: 14 athletes of different specialties accomplished a jump test with increasing weights, determining the overload level based on the value of 1MR, previously measured in the squat exercise with free bar. Results: The obtained results indicated that, when jumping with percentages under 40%, highest heights and potencies can be reached, being them significantly different (p<0,05) from the ones produced with percentages over 60% of 1MR. Moreover, when jumping with weights between 41% -50% and 51%-60% of 1MR, even if they do not observe significant differences, losses of potency superior to 10% and 20%, respectively are determined. Discussion: In accordance with these results, when accomplishing explosive exercises with different weight percentages, it is possible to distinguish three zones of work: Zone one or explosive strength (<40%-60%), Zone 2 or high average strength (<60 -90%) and Zone 3 or of maximum strength (>90%).
