Abstract:
We analysed peak 1-, 2- and 5-min periods and the associated 5-min recovery period in matches from three consecutive seasons in the Danish Superliga. A semi-automatic multicamera system was used to collect high-speed running distance (≥5.5 m/s; HSRD), sprint distance (≥7.0 m/s; SpD) and distance covered during intense acceleration (≥3 m/s2; AccD). Analysis included 479 players and 6042 to 9671 match observations using rolling average. Distances covered per minute during the peak periods were significantly higher than match averages: HSRD (207-772%), SpD (447-1793%), and AccD (383-1096%). Distances covered per min were lower during 1-min recovery periods than match average for HSRD following peak 1-, 2- and 5-min period (29%, 6%, 3%, 2%, 2%; 35%, 11%, 0%, 2%, 3%; and 45%, 29%, 13%, 8%, 4%; p < 0.05, respectively), and for SpD (20%, 3%, 7%, 3% (4% higher in the 5th min); 24%, 12%, 3%, 0%, 7%; and 39%, 29%, 18%, 17%, 12%; p < 0.05, respectively). Opposite, AccD increased in the following 1-min recovery periods following peak 1-, 2- and 5-min periods (68%, 89%, 94%, 88%, 90%; 47%, 86%, 93%, 90%, 88%; 23%, 56%, 76%, 85%, 87%; p < 0.05) compared to match averages. Intensity was higher during shorter periods, whereas performance decrements were largest after longer peak periods for HSRD and SpD, whereas no decrement was observed in AccD.
摘要:
我们分析了峰值1-,在丹麦超级联赛连续三个赛季的比赛中,2分钟和5分钟以及相关的5分钟恢复期。使用半自动多摄像机系统收集高速运行距离(≥5.5m/s;HSRD),冲刺距离(≥7.0m/s;SpD)和剧烈加速时的距离(≥3m/s2;AccD)。使用滚动平均值进行分析,包括479名球员和6042至9671名比赛观察。高峰时段每分钟覆盖的距离明显高于比赛平均值:HSRD(207-772%),SpD(447-1793%),和应计(383-1096%)。在1分钟恢复期内,每分钟覆盖的距离低于峰值1-之后的HSRD的匹配平均值,2-和5-min周期(29%,6%,3%,2%,2%;35%,11%,0%,2%,3%;和45%,29%,13%,8%,4%;p<0.05),对于SpD(20%,3%,7%,3%(第5分钟高出4%);24%,12%,3%,0%,7%;和39%,29%,18%,17%,12%;p<0.05)。相反,AccD在峰值1-之后的随后1分钟恢复期中增加,2-和5-min周期(68%,89%,94%,88%,90%;47%,86%,93%,90%,88%;23%,56%,76%,85%,87%;p<0.05)与匹配平均值相比。在较短的时期内强度较高,而HSRD和SpD的性能下降在较长的高峰时段后最大,而AccD中没有观察到下降。
