Week of crossfit® does not modify internal load, symptoms of stress and muscular pain
Abstract
The study analyzed the effects of a week of crossfit® training on internal load, symptoms of stress 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 Session Session Subjective Perception Method (PSIs) in all training sessions. Symptoms of stress (if) were measured by the Daily Analysis of Life Demands In Athletes (Dalda), while muscle pain (DM) measured from the visual analog scale of pain (EVA) both were applied at the beginning and end of week. It was observed that a week of CrossFit® training did not generate changes in internal load (PSIs1 = 175 ± 117 vs PSIs2 = 152 ± 95 vs PSIs 3 = 169 ± 92, p = 0.146), stress symptoms (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; = 0.1). It is concluded that a week of CrossFit® does not change internal training responses, stress symptoms and muscle pain.
