Table 1: Summary of physiological and performance changes before and after six Sprint Interval Training (SIT) sessions. Note, VO2 Peak testing was conducted prior to and after SIT. SIT power and work data were taken from the first four sprints of each session. *95% CI changes that failed to cross 0 (i.e., 0 change) were considered significant with a significant increase above initial values.
