WAYS OF EXPLOITATION THE POLAR TEAM PRO DATA IN CONDUCTING THE TRAINING PROCESS IN A COMPETITIVE FOOTBALL TEAM

Every coach has to be one step ahead of the competition so technological support is a must in this attempt. In the last decade, sophisticated analytics of the athletes' objective data has been a constant resource for improving the training process, thanks to advanced technology which has increasingly become a key-factor in pursuing this goal. The purpose of this study is to use Polar Team Pro data from Academica Clinceni football team, in order to plan the working loads of the players during training sessions, according the their positions and physiological-physical demands, related to the official game requirements. The parameters recorded during competitional period training sessions were: heart rate-percent of the HR max, the maximal and average speed, the total distance covered in each speed zone and number of sprints. The subjects belong to the Academica Clinceni football team, playing in League 2, all wearing the Polar Team Pro equipment, including the Polar Team Pro shirt, comprising sensors which transmits individual data to the iPad and the corresponding web service. After each training session, collected data fit into longitudinal reports, which help trainers and coaches to understand the evolution of the team in terms of physiological responses and physical preparation level. We analysed the data collected during training sessions, in October 2018, within the competitive season. Monitoring the players took place throughout the whole sessions, the data being collected and transmitted to the Polar Pro iPad on the field. The large array of variables recorded gives the possibility to compare and identify the relationships among them, individually and per team, so that precious guidelines can be drawn up and implemented on a regular basis during training sessions.每一位教练员都必须领先竞争对手一步，因此在此赛事备战与训练过程中，技术支持不可或缺。近十年来，依托先进技术对运动员客观数据开展的精细化分析，始终是优化训练流程的核心支撑；而此类技术也日益成为达成这一目标的关键要素。本研究旨在使用Academica Clinceni足球队的Polar Team Pro设备采集的数据，依据球员场上位置以及与正式赛事要求相关的生理、体能需求，规划训练期间球员的工作负荷。赛事周期内训练期间记录的参数包括：心率占最大心率（HR max）的百分比、最大速度与平均速度、各速度区间内的总跑动距离，以及冲刺次数。本次研究的受试者为征战于第二级别联赛（League 2）的Academica Clinceni足球队全体球员，他们均佩戴Polar Team Pro设备套装，其中包含Polar Team Pro运动胸带，该设备搭载的传感器可将个人数据传输至iPad及对应的网络服务平台。每次训练结束后，采集到的数据会被整合至纵向追踪报告中，助力教练员与体能训练师了解球队在生理反应与体能备战水平层面的变化趋势。本次研究分析了2018年10月赛事周期内训练期间采集的相关数据。训练全程均对球员进行监测，数据实时采集并传输至场边的Polar Pro iPad终端。本次采集的大量变量数据，支持开展个体与全队层面的对比分析，并可挖掘变量间的内在关联，从而能够制定并在训练中定期落地实施极具价值的训练指导方案。
