Table 2. Describes the average effect of HIIT modalities on the maximum rate of oxygen uptake, systolic blood pressure, and diastolic blood pressure, as related to the number of sessions performed.
HIIT: High-intensity interval training; V̇O2max: Maximum rate of oxygen uptake; SBP: Systolic blood pressure; DBP: Diastolic blood pressure.
*Papers used for calculations given that the respective parameters were met and statistical significance was provided in the results.
