Table 4 Results of meta-analyses in Progressive Resistive Exercise (PRE) and HIV systematic review: cardiorespiratory outcomes
Outcomes | Sub-Group Comparison of Meta-Analysis | # of Individual Studies Included in Meta-Analysis | Number of Participants Included in Meta-Analysis | Weighted Mean Difference (WMD) | 95% Confidence Interval | P value of overall effect | I2 statistic (p value for heterogeneity) | Interpretation |
|---|---|---|---|---|---|---|---|---|
VO2max (ml/kg/min) | PRE or combined PRE and aerobic exercise compared with no exercise | 3 studies | 82 | 3.71 ml/kg/minb | 1.73, 5.70 | 0.0002a | 0% (p = 0.84) | “Significant (and potential clinically important) improvement in change in VO2max among exercisers compared with non-exercisers.” [12]. |
Maximum Heart Rate (bpm) | PRE or combined PRE and aerobic exercise compared with no exercise | 3 studies | 65 | −5.23 beats per minute | −23.84, 13.37 | 0.58 | 97% (p < 0.00001) | “No significant difference in change in heart rate maximum among exercisers compared with non-exercisers.” [12]. |
Combined PRE and aerobic exercise group compared with no exercise | 2 studies | 43 | −4.91 beats per minute | −34.13, 24.30 | 0.74 | 99% (p < 0.00001) | “No significant difference in change in heart rate maximum among exercisers compared with non-exercisers.” [12]. | |
Exercise Time (min) | Combined aerobic and PRE group compared with no exercise | 3 studies | 83 | 3.29 min | 0.10, 6.49 | 0.04a | 97% (p < 0.00001) | “Significant increase in exercise time among exercisers compared with non-exercisers.” [12]. |
