The present prospective cohort study investigated changes in body composition (BC) in young male football players ( = 18, 16.1 ± 0.8 years; 181.0 ± 0.1 cm; 71.3 ± 4.9 kg) after combined football and strength training (ST) during a whole in-season period (26 weeks). BC was measured at whole-body absolute and regional levels by dual-energy X-ray absorptiometry in eighteen players at the beginning and at the end of the competitive period. The ST was organized into three different session types: ST in the gym, specific ST on the field, and individual ST (weak points). The results of the present study indicated that fat-free mass (FFM) was substantially higher following the competitive period (5.1% ± 1.2%), while percentage of fat showed no changes during the competitive period. At the regional level, arms' and legs' FFM increased at the end of the season, and bone mineral content (BMC) and density (BMD) increased in arms, legs, pelvis, thoracic spine, and lumbar spine. In conclusion, within the limitation of the potential positive impact of growth and/or maturation, present results seem to indicate that an ST program that supplements football-related training sessions could be an effective option to increase FFM, BMC, and BMD at both whole-body and regional level across the competitive season in young male professional football players.
本前瞻性队列研究调查了年轻男性足球运动员（n = 18，年龄16.1±0.8岁；身高181.0±0.1厘米；体重71.3±4.9千克）在整个赛季（26周）进行足球与力量训练（ST）相结合的训练后身体成分（BC）的变化。在赛季开始和结束时，通过双能X线吸收法对18名球员的全身绝对水平和区域水平的身体成分进行了测量。力量训练分为三种不同的类型：健身房力量训练、场上专项力量训练和个人力量训练（薄弱环节）。本研究结果表明，赛季结束后去脂体重（FFM）显著增加（5.1%±1.2%），而脂肪百分比在赛季期间没有变化。在区域水平上，赛季结束时手臂和腿部的去脂体重增加，手臂、腿部、骨盆、胸椎和腰椎的骨矿物质含量（BMC）和骨密度（BMD）增加。总之，在生长和/或成熟可能产生的积极影响的限制范围内，目前的结果似乎表明，在年轻男性职业足球运动员的整个赛季中，补充与足球相关训练课程的力量训练计划可能是增加全身和区域水平的去脂体重、骨矿物质含量和骨密度的有效选择。
