SMA – simple moving average, EWMA-W – exponentially weighted moving averages as per Williams et al. (2016), EWMA-L - exponentially weighted moving averages as per Lazarus et al. (2017), TL – training load, TSB – training stress balance, DIFF – differential load, VOL21 - the volatility (standard deviation) of values in the last 21 days prior to competition, CH21 - the value 21 days prior to competition subtracted from the value on the day of the competition. * - p<0.05, f2 – Cohen’s marginal effect size.
