Using the meta-analytic approach, the purpose of this study was to exa
mine the effects of aerobic exercise on resting systolic (SYS) and dia
stolic (DIA) blood pressure in normotensive adults. The results of 35
human clinical training studies published in English-language journals
between 1963 and 1992 and representing 1,076 subjects (800 exercise,
276 control) met criteria for inclusion. Across all categories and des
igns, statistically significant post-exercise reductions were found fo
r both SYS and DIA blood pressure (($) over bar X +/- SD, SYS: -4.4 +/
- 6.6 mm Hg, 95% CI, -6.2 to -2.6 mm Hg; DIA: -3.2 +/- 3.2 mm Hg, 95%
CI, -4.0 to -2.2 mm Hg). When partitioned according to type of study:
1) (randomized controlled trials (RCT), 2) controlled trials (CT), and
3) no controls (NC), the following changes were noted: RCT, SYS: -4.5
+/- 7.2 mm Hg, 95% CI, -7.1 to -1.2 mm Hg; DIA: -3.8 +/- 2.9 mm Hg, 9
5% CI, -5.0 to -2.6 mm Hg; CT, SYS: -2.8 +/- 6.9 mm Hg, 95% CI, -10.0
to 4.4 mm Hg; DIA: -5.0 +/- 3.7 mm Hg, 95% CI, -8.9 to -1.1 mm Hg; NC,
SYS: -4.7 +/- 6.1 mm Kg, 95% CI, -7.5 to 1.9 mm Hg; DIA: -1.7 +/- 3.0
mm Hg, 95% CI, -3.2 to -0.36 mm Hg. We concluded that aerobic exercis
e results in small reductions in resting SYS and DIA blood pressure am
ong normotensive adults.
