Abstract

Background: This study is one of the first to specifically analyze cardiorespiratory fitness and its association with age, weight, height, body fat percentage (BFP), body mass index (BMI), team performance, and player position for a large number of soccer players in an Asian top league. Methods: 213 players (age = 25 ± 5 years, height = 181.2 ± 6.8 cm, weight = 76.1 ± 8.1 kg, BFP = 11.3 ± 3.1) affiliated with 16 soccer clubs from Iran’s Premier League (i.e., the highest level of club football in Iran), were tested for maximal aerobic power (VO2 max), first and second ventilatory thresholds (VT1 and VT2), and ventilatory efficiency at rest (VO2 rest). The nonparametric Spearman's correlation test was performed to check for correlations, and the resulting rank correlation coefficients (rs) and probability value (P) are presented. Results: In terms of mean ± standard deviation, the 213 male players participating in this study have VO2max = 55.3 ± 5.4 mL.kg-1.min-1, VT1 = 57.3 ± 4.2 (% max), VT2 = 92.6 ± 3.4 (% max) and VO2rest = 7.1 ± 1.4 mL.kg-1.min-1. No correlation between VO2max and team performance or BFP was observed. The correlations between VO2max and age (rs= -0.23, P = 10-3), height (rs = -0.34, P ≅ 0), weight (rs = -0.42, P ≅ 0) and BMI (rs = -0.30, P = 10-5) were considered statistically significant. The difference between VO2max of players in different positions was also statistically significant. Goalkeepers possessed the lowest VO2max, with a mean value of 49.8 mL.kg-1.min-1. Defenders had the lowest mean VO2max value players (equal to 54.7 mL.kg-1.min-1) amongst outfield, and midfielders had the highest mean VO2max (= 56.9 mL.kg-1.min-1). The other indices of cardiorespiratory fitness (VT1, VT2 and VO2rest) had no statistically significant correlation with the physical characteristics of the soccer players, team performance and player position. Conclusions: The study demonstrates that VT1, VT2, and VO2rest are not distinguishing factors amongst different categories of age, weight, height, team performance, and player position, but VO2max varies with age, weight, height, and BMI. The study also showed that there is a high correlation between the physical demands of player positions during a game and the aerobic capacity of players in those positions, and this must be taken into account in soccer training.
伊朗足球高级联赛球员心肺健康评价及其与球队成绩、球员位置和身体特征的关系
背景:本研究是第一个专门分析亚洲顶级联赛大量足球运动员的心肺健康及其与年龄、体重、身高、体脂率(BFP)、身体质量指数(BMI)、球队表现和球员位置的关系的研究之一。方法:对16家伊朗足球俱乐部(即伊朗足球最高水平的俱乐部)的213名球员(年龄= 25±5岁,身高= 181.2±6.8 cm,体重= 76.1±8.1 kg, BFP = 11.3±3.1)进行了最大有氧能力(VO2 max)、第一和第二通气阈值(VT1和VT2)和休息时通气效率(VO2休息)的检测。采用非参数Spearman相关检验检验相关性,并给出秩相关系数(rs)和概率值(P)。结果:213名参与本研究的男性运动员VO2max = 55.3±5.4 mL.kg-1。min-1, VT1 = 57.3±4.2 (% max), VT2 = 92.6±3.4 (% max), VO2rest = 7.1±1.4 ml .kg-1 min-1。VO2max与团队表现或BFP之间没有相关性。VO2max与年龄(rs= -0.23, P = 10-3)、身高(rs= -0.34, P = 0)、体重(rs= -0.42, P = 0)、BMI (rs= -0.30, P = 10-5)的相关性具有统计学意义。不同位置球员的最大摄氧量差异也有统计学意义。守门员的最大摄氧量最低,平均值为49.8 ml .kg-1 min-1。后卫球员的VO2max平均值最低(54.7 ml .kg-1 min-1),中场球员的VO2max平均值最高(56.9 ml .kg-1 min-1)。其他心肺适能指标(VT1、VT2和VO2rest)与足球运动员身体特征、球队表现和球员位置均无统计学意义。结论:研究表明,VT1、VT2和VO2rest在年龄、体重、身高、球队成绩和球员位置的不同类别中不具有显著性,但VO2max与年龄、体重、身高和BMI相关。该研究还表明,在比赛中,球员位置的身体需求与球员在这些位置上的有氧能力之间存在着高度的相关性,这在足球训练中必须考虑到。
