| Resumen en español | 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%) |

| Resumen en portugués | O objetivo do estudo foi analisar as diferenças entre as alturas ou potências produzidas em um teste de saltos com pesos crescentes utilizando diferentes porcentagens de uma Repetição Máxima (1RM), assim como identifi car as zonas de pesos onde se alcançam as potências altas e aquelas onde não é possível saltar. Materiais e Métodos: 14 esportistas de diferentes especialidades realizaram um teste de saltos com pesos crescentes, determinando o nível de sobrecarga com base no valor de 1RM, medido previamente no exercício de agachamento com barra livre. Resultados: Os resultados obtidos indicaram que, ao saltar com porcentagens menores que 40%, se alcançam as maiores alturas e potências, sendo signifi cativamente diferentes (p<0,05) das produzidas com porcentagens maiores que 60% da 1RM. Além disso, ao saltar com os pesos compreendidos entre 41%-50% e 51%-60% da 1RM, mesmo que não se observem diferenças signifi cativas, se determinam perdas de potência superiores a 10% e 20%, respectivamente. Discussão: De acordo com estes resultados, ao realizar exercícios explosivos com diferentes porcentagens de peso, podem se distinguir três zonas de trabalho: Zona 1 ou de força explosiva (menor que 40% a 60%), Zona 2 ou de força média alta (maior que 60% a 90%) e Zona 3 ou de força máxima (maior que 90%) |
