Table 2. Effects of HIIT versus MICT on VO2max and systolic blood pressure/diastolic blood pressure after eight weeks: A) Intention-to-treat analysis, and B) per-protocol análisis.
| A. Intention to treat analysis | ||||
|---|---|---|---|---|
| Variables | HIIT (n=22) | MICT (n=22) | Differences between groups (post-intervention) | p |
| VO2máx (ml/kg/min)* | 42.7 (6.0) | 44.1 (8.7) | 0.98 (-2.26 to 4.23) | 0.54 |
| SBP (mm Hg)** | 124.5 (120.0-129.5) | 116.5 (115.0-119.0) | 8.0 | <0.001‡ |
| DBP (mm Hg)** | 79.2 (76.0-85.0) | 79.0 (71.5-83.0) | 0.2 | 0.15 |
| B. Subjects who completed the protocol | ||||
| Variables | HIIT (n=18) | MICT (n=18) | Differences between groups (post-intervention) | p |
| VO2máx (ml/kg/min)* | 44.0 (5.8) | 45.1 (8.9) | 0.50 (-2.64 to 3.63) | 0.75 |
| SBP (mm Hg)** | 125.7 (120.0-129.5) | 117.2 (115.5-121.0) | 8.5 | 0.0005‡ |
| DBP (mm Hg)** | 79.2 (75.0-85.0) | 79.2 (71.5-83.0) | 0.0 | 0.26 |
For maximum oxygen consumption (VO2máx), values were adjusted for base line and confounding variables (age, body mass index, weight and height).
SBP: Systolic blood pressure; DBP: Diastolic blood pressure
* Values are given as mean ± SD.
** Values are given as medians and interquartile ranges.
