Relationship between sprint time, cardiovascular fitness and SRPE during in-season\s training among professional soccer players

The purpose of this study was to examine the relationship between sprint time, cardiovascular  fitness and session's rate of perceived exertion (sRPE) among the professional soccer players  during the seventy sessions of in-season's training. Thirty participants who officially registered  as Perbadanan Kemajuan Negeri Perak Football Club professional soccer players participated in this  study. The quasi-experimental research design was used and the data were collected during actual  in-season training sessions from December 2016 to April 2017. Sprint time performance was  determined by using the 20m sprint test and the 20m Yoyo Intermittent Recovery Test Level I was  used to determine the cardiovascular fitness level of the players. Ten scales rating for the sRPE  was asked at the end of each training to determine the self-perception intensity of the players.  Pearson Correlation was used to analyze the empirical data. The result showed a moderate but  negative significant correlation between sprint time performance and sRPE (r=-0.36, p
