Evaluation of neuromuscular fitness in crossfit practitioners
Abstract
Crossfit is a modality of physical training that has gained popularity for its innovative and challenging character, however its morphofunctional responses are still empirical. Thus, this study aimed to assess the body composition and neuromuscular fitness of Crossfit practitioners. The sample consisted of 22 students with an average age of 28.28 (± 7.55) years, evaluated bimonthly for six months. The assessment of body composition variables was performed by calculating body mass index, waist-to-hip ratio, waist circumference and analysis of body composition by skinfolds. The assessment of neuromuscular fitness was characterized by the analysis of muscle strength performance through the test of a maximum repetition (1-RM); muscular endurance, through abdominal resistance and arm flexion tests in one minute and specific angular flexibility by goniometry. The results showed that there were no statistically significant changes in the sample's body composition in any of the evaluated parameters as well as in the neuromuscular fitness parameters (strength, muscular endurance and flexibility). However, in an analysis of its absolute values, it showed a tendency to gain muscle strength and shoulder flexibility. Thus, the practice of Crossfit did not promote significant changes in body composition and neuromuscular fitness in the investigated sample.
