Abstract
The purpose of this study was to determine the relationships between body composition, strength, power characteristics, sprinting, jumping, and intermittent endurance performance in collegiate male players. Twenty-three players participated (19.7 ± 1.6 yrs; 71.8 ± 7.1 kg; 176.5 ± 5.1 cm). Measurements of interest in body composition included body fat percentage (BF%), lean body mass (LBM), and body mass (BM). Power characteristics were measured with an unloaded squat jump (SJ0) and loaded SJ at 20 kg (SJ20) and 40 kg (SJ40), and unloaded countermovement jump (CMJ0). Power assessments included peak power (PP) and PP allometrically scaled (PPa). Strength characteristics were assessed using isometric mid-thigh pull. Strength assessment included isometric peak force (IPF) and IPF allometrically scaled (IPFa). Performance measures included 10m and 20 m sprint time, CMJ0 jump-height, and Yo-Yo intermittent endurance test level 1 distance. Significant correlations ranging from moderate to very large were found for LBM and CMJ jump height (CM0 JH) (p = 0.01, r = 0.50); BF% and sprint times at 10 m (p = 0.03, r = 0.44) and 20 m (p = 0.02, r = 0.50). PP and PPa from SJ0 and CMJ0 were significantly correlated to 10m sprint time (p < 0.05, r = −0.45 to −0.53) and 20 m sprint time (p < 0.05, r = −0.40 to −0.49). Our findings agree with previous literature in that body composition and power characteristics are directly related to soccer-related performance.
Highlights
Soccer is one is the most popular sports in the world that can be categorized as an intermittent sport consisting of sprinting, walking, jogging, jumping, kicking, and heading [1]
Significant large correlations were found between lean body mass (LBM) and Countermovement jump (CMJ) JH
Non-statistically significant correlations were observed for Yo-Yo intermittent endurance test level 1 (YYIR1) and LBM (p > 0.05, r = −0.09), BF% (p > 0.05, r = −0.05), and body mass (BM) (p > 0.05, r = −0.12)
Summary
Soccer is one is the most popular sports in the world that can be categorized as an intermittent sport consisting of sprinting, walking, jogging, jumping, kicking, and heading (i.e., soccer-related performance) [1]. Maximum strength and power are crucial factors to improve the multifaceted capacity, such as sprinting and jumping [2,3], and endurance performance [4,5]. Muscle strength and power output have been directly associated with a player0 s ability to perform sprints (e.g., getting away from a defender) and jumps (e.g., attempting to head a ball) in male soccer [7,8,9]. It may be beneficial for soccer players to improve maximum strength and power, which could lead to maximizing soccer-related sports performance
