    本手稿的目的是研究国际橄榄球7队在奥运会期间的分期策略。在2015-2016年奥运会期间,在48周内收集了14名精英男性球员的训练负荷数据。本赛季由3个大周期组成,包括:季前赛(12个弱持续时间),赛季中(25弱)分为四个4-7周的中环(In-1-4)和2016年里约奥运会的最后准备(奥运会准备,11-弱)。外部训练负荷(TL),如总距离(TD),高强度距离(HID)和执行的加速度的数量,在整个赛季的训练和比赛中使用全球定位系统(GPS)设备进行监控。将感知努力(RPE)的等级乘以会话持续时间(min),以提供所有培训课程和比赛的内部TL(会话RPE)值。与季前赛(TD,21±13%,中等;总加速度,27±4%,中度),而这两个时期之间的内部TL值没有差异。高强度距离(HID)和内部TL(Session-RPE)较低(-11.0±7.8%,小和-38±3%,中度,分别)在赛季中与季前赛相比。内部TL,与第一个季节中环(In-1)相比,第三个季节中环(In-3)的TD和HID较低(-25±12%,中等;-32±4%,中等;-49±8%,中度,分别)。工作人员考虑到赛季中作为“通往里约之路”的主要部分来管理工作量。“在赛季中期减少工作量并在赛季结束时诱导数周再生的战略在奥运会准备开始时得到了100%的训练。奥运赛季的工作量分期策略不同于先前在非奥运赛季期间描述的策略。
    The objective of this manuscript was to examine the periodization strategy of an international Rugby-7s team during an Olympic season. Training load data were collected in 14 elite male players over a 48-week period during the 2015-2016 Olympic season. The season consisted of 3 macrocycles including: preseason (12-weak duration), in-season (25-weak) fragmented into four 4-7 weeks mesocycles (In-1-4) and the final preparation for the Rio 2016 Olympic Games (Olympic preparation, 11-weak). External training load (TL) such as the total distance (TD), the high-intensity distance (HID) and the number of accelerations performed, was monitored in training and competition over the entire duration of the season using a global positioning system (GPS) devices. The rating of perceived exertion (RPE) was multiplied by the session duration (min) to provide an internal TL (session-RPE) value for all training sessions and competitions. The Olympic preparation may enable planning of higher external TL compared to the preseason (TD, 21 ± 13%, moderate; total accelerations, 27 ± 4%, moderate) whereas no difference was observed for internal TL values between these two periods. High-intensity distance (HID) and internal TL (session-RPE) were lower (-11.0 ± 7.8%, small and -38 ± 3%, moderate, respectively) during the in-season compared to preseason. Internal TL, TD as well as HID were lower in the third in-season mesocycle (In-3) compared with the first in-season mesocycle (In-1) (-25 ± 12%, moderate; -32 ± 4%, moderate; -49 ± 8%, moderate, respectively). The staff managed the workload considering the in-season as the main part of the \"Road to Rio.\" The strategy to reduce the workload at the middle of the season and to induce weeks of regeneration at the end of the in-season was highlighted by the training availability of 100% of the squad at the beginning of the Olympic preparation. The workload periodization strategy of an Olympic season differs from the strategy previously described during a non-Olympic season.

    目前,大多数篮球研究都集中在职业和精英球员身上。业余水平的研究对于解释比赛的身体和技术要求,从而提高球员和球队的表现非常重要。本研究的目的是描述业余水平篮球队的竞争需求,并分析不同情境变量对身体和技术性能指标的影响。11名业余高级篮球运动员在2018/2019赛季参加了六场正式的决赛。外部,内部载荷,和符号分析由惯性设备注册,心率带,视频分析。Kruskal-WallisH检验用于根据比赛位置进行比较,perments,最后一个季度的比赛结果,事后比较由曼-惠特尼U测试完成。实现了Spearman相关系数的关系分析。结果表明:(a)后卫覆盖了更多的位移量(场上有效时间:p<0.01,ER2=0.05;步数/分钟:p<0.01,ER2=0.28),中锋进行了较高负荷的比赛动作([>8G]Imp/min:p<0.01,ER2=0.20;跳跃/min:p<0.01,ER2=0.33);(b)在比赛的第一场比赛而在不平衡的游戏中,看到了更多的高强度冲击([>8G]Imp/min:p<0.01,ER2=0.07)。分析的情境变量对业余高级篮球运动员的运动表现有影响,应在正式比赛中设计训练课程和计划策略时予以考虑。
    Currently, most basketball research is focused on professional and elite players. Studies at the amateur level are important to explain the physical and technical demands of competition and thus improve players\' and teams\' performance. The purpose of the present study was to describe the competitive demands of an amateur-level basketball team and to analyze the influence of different situational variables on the physical and technical performance indicators. Eleven amateur senior basketball players participated in six official final-round games during the 2018/2019 season. External, internal load, and notational analysis were registered by inertial devices, heart rate bands, and video analysis. The Kruskal-Wallis H-test was applied for comparisons based on playing positions, periods, and final quarter game outcome, with the post hoc comparison accomplished by a Mann-Whitney U test. The Spearman correlation coefficient was realized for the relational analysis. The results showed that: (a) guards covered more volume of displacements (effective on-court time: p < 0.01, E R 2 = 0.05; steps/min: p < 0.01, E R 2 = 0.28) and the centers performed competitive actions of higher load ([>8G] Imp/min: p < 0.01, E R 2 = 0.20; jumps/min: p < 0.01, E R 2 = 0.33); (b) a performance decreasing was found between the first and second half of the game; (c) in balanced matches there was the most individual technical performance (PIR/min: p < 0.98, E R 2 = 0.01), while in the unbalanced games more high-intensity impacts were seen ([>8G] Imp/min: p < 0.01, E R 2 = 0.07). The situational variables analyzed had an influence on athletic performance in amateur senior basketball players and should be considered for designing training sessions and planning strategies during official matches.
