INFLUÊNCIA DA INTENSIDADE DE CORRIDA NA POTENCIALIZAÇÃO DO SALTO EM CORREDORES RECREACIONAIS E INDIVÍDUOS FISICAMENTE ATIVOS

Abstract

Post-activation performance enhancement (PAPE) is an acute improvement in physical exercise performance after maximal or submaximal conditioning activity (CA). PAPE has been associated with trained individuals, and seems to be influenced by the individual conditioning level and CA intensity. However, the influence of CA intensity on PAPE in endurance events in individuals with different levels of physical conditioning is unclear. The aim of this study was to verify the effect of two runs, with different intensities on the PAPE, in individuals with different levels of physical conditioning. Eighteen men, divided into two groups: 9 recreational runners (34.5±9.3 years, 73.1±11.9 kg, 1.76±0.06 m, 17.4±4.4% fat; 16.4±1.0 Km.h-1/maximum aerobic speed-MAS), and 9 physically active individuals (34.1±9.4 years; 83.2±7.7 kg; 1.79±0.06 m; 25.6±5.4% fat; 13.3±1, 2 Km.h-1/MAS) performed two counter-movement jumps (CMJ) and two sprints pre and post-running intervention. Participants underwent a maximal incremental test (University Montreal Track Test – UMTT) to determine the MAS and distance to be completed in the interventions (70% of MAS and time trial race- TTR). The interaction of CMJ and SPRINT with time, intervention, and group was analysed trhough an ANOVA three-way. A significant difference in the time (F = 10.716; p < 0.01) and intervention*group interaction (F = 12.094; p < 0.01), with an increase in the height of the CMJ in 7.6% post-intervention at 70% of MAS for activie individuals and 6.9% post TTR for recreational runners, respectively. No significant difference was observed for SPRINTs. In conclusion, active individuals had higher PAPE in CMJ after intervention at 70% of MAS, while recreational runners presented PAPE after both interventions (70% of MAS and TTR), indicating that the greater intensity can influence the performance according to physical conditioning.
