Efeito da interferência entre treinos concorrentes do tipo força e aeróbio versus do tipo aeróbio e força

Abstract

With its distinctive methodology, CrossFit incorporates functional movements that are constantly varied and performed at high intensity. The goal is to develop overall physical fitness to the fullest extent possible, utilizing concurrent training by blending gymnastics, aerobic and resistance exercises in the same workout session, thereby inducing the interference effect in its practitioners. Interference refers to the combination of different physical qualities in training with little or no rest between them. In the context of CrossFit, it is common to integrate strength exercises with aerobic exercises. In this study, the goal is to investigate if there is interference in training sessions performed in the order of strength/aerobic and aerobic/strength, and identify which of the two sequences of concurrent training induces greater interference. Fourteen volunteers, CrossFit practitioners, were tested for 1RM deadlift, maximal aerobic performance in burpees, and performance in the deadlift at 70% 1RM in isolated situations and concurrent training scenarios to assess the impact of strength training on aerobic performance and vice versa. The main findings indicate that both types of training interfere with subsequent test performance, with aerobic training having a greater impact on strength test performance.
