The impact of landing forces on repeated jumping performance
Original language description
BACKGROUND: High -velocity concentric actions can be negatively impacted by cumulative fatigue during plyometric training. Reducing vertical ground reaction forces (GRF) upon landing could decrease eccentric demands, potentially minimizing fatigue, maintaining concentric performance, and benefiting concentric training adaptations. Therefore, this study examined the effect of intentionally higher and lower landing vertical GRF on the ability to sustain concentric jumping performance. METHODS: Twenty men (25.2 +/- 3.5 years) performed 30 maximal effort jumps over a 50 cm hurdle (high -landing GRF) and onto a 50 cm box (low -landing GRF), on two separate occasions in a counter -balanced order. Jumps were measured using two force platforms (one for takeoff and one for landing) and a linear position transducer. The 30 jumps were divided into 5 groups of 6 repetitions, and the mean value for each group was analyzed. RESULTS: There was no significant condition x repetition group interaction for any parameters, indicating that the greater landing GRF during hurdle jumps did not negatively affect concentric jump performance throughout the 30 jumps. Concentric velocities and jump height were significantly greater during box jumps compared to hurdle jumps. CONCLUSIONS: Thirty maximal -effort jumps did not cause fatigue -related decrease of performance, independent of jump type ( i.e. , the magnitude of landing GRF). Although, reduced vertical GRF upon landing appears to have a neutral -to -positive effect on concentric jumping performance. Therefore, reducing landing GRF, such as by using BJs, could acutely augment jumping performance and help to reduce cumulative training load.
