Soccer_GPS_MFDFA_entropy

Velocity-derived data in elite women soccer player during official games. Position are playing positions (MO: Offensive Midfielder, A: Attackers, DC: Central Defenders, DL: Lateral Defenders, MD: Medial Defenders). Columns are xxx_YYY with xxx is the outcome and YYY is the game segment. xxx: Mean is mean velocity. CV is coefficient of variation, Max is maximum velocity, ApEn is approximate entropy, SampEnn is Sample entropy, H2 is the Hurst exponent with q = 2, Frac_max and Frac_peak are maximum and peak values from the multifractal (MFDFA) analysis. YYY: Game is the entire game, MT1 and MT2 are the first and second half-times, Q1, Q2, Q3 and Q4 are the four quarters of the game. MFDFA is the multifractal detrended fluctuation analysis. Analyses are conducted using R.
