The purpose of this study was to observe the changes in body composition of collegiate marching band artists after a competitive season NCAA Division I football season. Thirty-seven marching artists (7 females, 31 males; age: 21.5 (1.4) years; height: 177.2 (9.5) cm had body fat percentage (BF%), fat mass (FM), android adiposity, gynoid adiposity, bone mineral content (BMC), and lean soft tissue (LST) measured before and after a competitive season of Division I football. Body composition measures were conducted using single-frequency bioelectrical impedance analysis device (Quantum IV, RJL systems, Clinton MI). Pre- and post-season differences in anthropometrics and body composition were evaluated using repeated measures analysis of variance with Cohen's statistics to estimate the magnitude of effect. Over the 15 weeks, participants experienced an average body mass loss of -0.4 (2.5) kg (=0.17). BF% and FM increased on average by 1.4 (1.8)% (=0.78) and 0.95 (1.8) kg, respectively. There were small increases in both android (0.08 (0.2) kg; =0.36) and gynoid (0.10 (0.3) kg; =0.38) fat throughout the season. Additionally, BMC showed a trivial increase of 0.002 (0.1) kg (=0.02), despite a large decrease in mean LST (-1.40 (1.3) kg; =1.06). Nutrition and physical activity level may have led to physical changes. Interventions designed to maintain adiposity throughout a season may be necessary. Additionally, resistance training programs may be appropriate to help maintain or increase LST throughout a season. Healthcare providers should be aware of changes in body composition which may lead to higher prevalence of injuries.
本研究的目的是观察美国大学体育协会（NCAA）第一分区橄榄球赛季竞技赛后，大学行进乐队艺术家的身体成分变化。37名行进乐队艺术家（7名女性，31名男性；年龄：21.5（1.4）岁；身高：177.2（9.5）厘米）在第一分区橄榄球赛季竞技赛前和赛后测量了体脂百分比（BF%）、脂肪量（FM）、腹部肥胖、臀部肥胖、骨矿物质含量（BMC）和瘦软组织（LST）。使用单频生物电阻抗分析仪（Quantum IV，RJL systems，克林顿，密歇根州）进行身体成分测量。使用重复测量方差分析和科恩效应量统计评估赛季前后人体测量学和身体成分的差异，以估计效应大小。在15周内，参与者的平均体重减轻了-0.4（2.5）千克（效应量=0.17）。BF%和FM平均分别增加了1.4（1.8）%（效应量=0.78）和0.95（1.8）千克。整个赛季腹部脂肪（0.08（0.2）千克；效应量=0.36）和臀部脂肪（0.10（0.3）千克；效应量=0.38）均有小幅增加。此外，尽管平均LST大幅下降（-1.40（1.3）千克；效应量=1.06），BMC仍有0.002（0.1）千克的微小增加（效应量=0.02）。营养和身体活动水平可能导致了身体变化。可能需要设计干预措施来在整个赛季维持肥胖水平。此外，抗阻训练计划可能有助于在整个赛季维持或增加LST。医疗保健提供者应注意身体成分的变化，这可能导致受伤发生率升高。
