Revisando o treinamento complexo: meta-análise das implicações agudas no desempenho da potência de membros inferiores e superiores

Abstract

The complex training may be associte increased in power performance of upper and lower limbs. However, the inumerous methodological dign does not provide conclusive data. An example of this is the lack of consensus on the optimal range of recovery after the conditioning actions. Therefore, this master´s thesis reviewed the extend and quality of the studies on the acute effects of differents rest intervals on the height of jump, as well as the power performance in bench press throw, after conditioning actions. The results suggest that the complex training does not induce transient increases in power produced by the exercise bench throw. When provided recovery intervals below three minutes there was a decrease in the height jump. However, one of the main findings of this work was that for rest intervals between 8 and 12-minute enhanced the jump height. The balance between the effects of fatigue and PAP is a key factor for implementation of the strategy. Thus, the absence of changes in bench throw performance may be due to a common effect of the variability of PAP between the subjects of the studies, as well as an equivalent effect between PAP and fatigue. When it was given short intervals (0-3 minutes) jumping performance was impaired, it may be associated with a prevalence of the effects of fatigue on the PAP, which may involve release and decreased sensitivity of muscle fibers to Ca 2+, such as increases in intracellular inorganic phosphate, thus decreasing the force of contraction of cross bridges. However, for 8-12 minutes intervals between the effects of fatigue succumbed to PAP. These changes may be associated with conformational changes in cross bridges, as well as muscle activation optimization, leading to improvements in the neuromuscular performance of specific exercise. Thereby, the complex training presents an interesting acute strategy to improve jump height. Furthermore, the results show a small benefit for exercising bench throw.
