Relationship of the phase angle with the maximum and explosive force in soccer players from Bogotá

Abstract

Abstract The phase angle (AF) obtained by electrical bioimpedance (BIE) analyzes the muscle composition by establishing the amount of water and electrolytes as indicators of cell size, number, and integrity, as essential body composition axes to determine training objectives and states of Health. Objective To determine the relationship between AF and maximum force (FM) and explosive (FME) in soccer players from Bogotá-Colombia. Methods Cross-sectional study of correlational scope. 86 players were selected (age: 18.67 ± 2.9 years; height: 1.73 ± 0.070 m; weight: 66.58 ± 9.94 kg) team members: Fortaleza, Tigres, Juventus, and Dinhos. The following were evaluated: body composition using InBody® 770; FM using T-Force® and FME (SJ) with optogait®. Results AF 6,46 ±0,58, FM in squats 614,4N ±262,28, maximum squat power 326,34W ±182,16 and maximum jump power SJ 649,7W ±117. There was a statistically significant relationship between musculoskeletal mass (0.598 p = 0.000),% body fat mass (-0.458 p = 0.000), peak FM (0.639 p = 0.000), maximum peak power (0.569 p = 0.000), maximum jump power (-0.636 p = 0.000) and AF. AF is associated with variables of body composition and muscle strength, making it an instrument that could help predict physiological behavior in soccer players and the general population. It shows correlations and markers applicable to sports and clinical diagnosis that will allow generating health promotion programs. Key messages The AF is constituted as an easily accessible marker for nutritional health and functional profile in athletes. AF is associated with variables of body composition and muscle strength, making it an instrument that could help predict physiological behavior in soccer players and the general population.
