摘要

目的:使用便携式全球定位系统,确定同一俱乐部的甲级成年球员和U-19球员在非官方比赛中的内外负荷差异。方法:在一名成年人和U-19类别的非官方比赛中,通过心率监测内部负荷,通过跑步表现监测外部负荷。对7名成年球员(25.57±5.06岁)和5名U-19球员(18.6±0.54岁)进行了监测。使用Mann-Whitney U检验对上半场、下半场和总匹配的类别进行比较,并通过百分比差异(PD)计算效果大小。结果:上半场和整场比赛外负荷在最高速度上存在差异(p<0.05),U-19选手达到最高值(上半场最高速度:32.34vs27.77km/h,PD=15.3%;整场比赛:32.6vs28.14km/h,PD=14.7%),在上半场和下半场,内部负荷的差异仅出现在心率3区(最大HR的70%至80%),U-19球员在该区的时间更长(心率3区上半场:6.1分钟对1.73分钟,PD=111.6%;下半场:20.49分钟对5.21分钟,PD=118.8%)。在分析的其他变量中没有发现差异。结论:从获得的结果中,我们可以得出结论,除了在非官方比赛中该队的最高速度和心率3区外,U-19成年球员的内外负荷没有差异。因此,出于实际目的,这支球队的U-19球员可能有条件面对成人类比赛所需的身体需求。

Differences in internal and external load between adult and youth soccer players in a friendly match
Objective: To determine differences in internal and external load during an unofficial match between First Division Adult and U-19 players of the same club using portable global positioning systems. Methods: During an unofficial match between an adult and a U-19 category, internal load through heart rate and external load through running performance were monitored. Seven adult players (25.57 ± 5.06 years) and five U-19 players (18.6 ± 0.54 years) were monitored. Comparisons were made between categories in the first half, second half and total match using the Mann-Whitney U test and calculating effect sizes through percent difference (PD). Results: Differences were found (p<0.05) of external load in maximum speed in first half and total match, with U-19 players reaching the highest values (maximum speed first half: 32.34 vs 27.77 km/h and PD = 15.3%; total match: 32.6 vs 28.14 km/h and PD = 14.7%). On the other hand, differences in internal load were only found in heart rate zone 3 (70 to 80% of maximum HR) in the first and second half, where U-19 players spent more time in this zone (heart rate zone 3 first half: 6.1 vs 1.73 minutes and PD = 111.6%; second half: 20.49 vs 5.21 minutes and PD = 118.8%). No differences were found in the other variables analyzed. Conclusion: From the results obtained we can conclude that there are no differences in internal and external load in adult players with U-19 players, except for maximum speed and heart rate zone 3 in this team during a non-official match. Therefore, for practical purposes, the U-19 players of this team could be in conditions to face the physical demands required by the adult category competition.
