Uma semana de Crossfit® não modifica carga interna, sintomas de estresse e dor muscular
2019
The study examined the effects of a week of Crossfit® training on internal workload, stress symptoms, and muscle pain. The sample consisted of 21 men (25 ± 4 years) and 18 women (23 ± 3 years). The internal load was measured by the Subjective Session Effort Perception (RPES) method in all training sessions. Stress symptoms (SE) were measured by the Daily Analysis of Life Demands in Athletes (DALDA), while muscular pain (DM) was measured from the Visual Analog Pain Scale (EVA) both were applied at the beginning and end of the week. It was observed that a week of Crossfit® training did not generate changes in the internal load (RPES 1 = 175 ± 117 vs RPES of session 2 = 152 ± 95 vs RPES of session 3 = 169 ± 92, p = 0.146), (Pre = 2.95 ± 2.1 vs Post = 3.21 ± 1.5; Effect size = -0.1) and muscle pain (Pre = 2.13 ± 0.9 vs Post = 2, 00 ± 0.8, Effect size = 0.1). It is concluded that a week of CrossFit® does not change the responses of internal training load, stress symptoms and muscular pain.
