COMPARISON OF THE MOTIVATION LEVEL OF SOCCER PLAYERS WITH HIGH AND LOW PLAYED TIME IN MATCHES UNDER-20

ABSTRACT An athlete’s motivation is deemed one of the most important elements to achieve success in sports career. The aim of this study was to compare the motivation level of football athletes with long playtime (LPT) and short playtime (SPT) in a competition. The study assessed 112 federated athletes (18.58±1.06 years old) participating in Minas Gerais’s Under-20 Football Championship (2015), by means of the Sport Motivation Scale (SMS). The athletes’ playtime (PT) in the championship’s qualifying rounds was registered through the analysis of 48 official referee report forms. The athletes were grouped according to their PT - SPT ≤25% (≤184 minutes) and LPT ≥75% (≥513 minutes). Results showed that those with LPT presented higher levels of self-determination and higher scores of intrinsic motivation compared to SPT athletes (p摘要 运动员的动机是其职业生涯取得成功的关键要素之一。本研究旨在对比参赛足球运动员中长上场时间（Long Playtime, LPT）与短上场时间（Short Playtime, SPT）群体的动机水平。研究通过运动动机量表（Sport Motivation Scale, SMS），对参与2015年米纳斯吉拉斯州U20足球锦标赛的112名注册运动员（年龄18.58±1.06岁）开展评估。通过分析48份官方裁判报告，记录了运动员在该赛事预选赛阶段的上场时间（Playtime, PT）。研究按照上场时间将运动员分为两组：短上场时间组（SPT）为上场时间占比≤25%（≤184分钟），长上场时间组（LPT）为上场时间占比≥75%（≥513分钟）。结果显示，相较于短上场时间组运动员，长上场时间组运动员的自我决定动机水平更高，内在动机得分也更高（p
