Why the study?
Does short-term exercise reduce resting systolic and diastolic blood pressure in children and adolescents?
Does short-term exercise reduce resting systolic and diastolic blood pressure in children and adolescents?
Short-term exercise does not appear to significantly reduce resting systolic and diastolic blood pressure in children and adolescents based on this meta-analysis.
Short-term exercise does not support resting BP reduction in youth; challenges assumptions of acute benefits and directs research to sustained interventions.
Resting blood pressure in children and adolescents can track into adulthood. The purpose of this study was to use the meta-analytic approach to examine the effects of exercise on resting systolic and diastolic blood pressure in children and adolescents. Twelve randomized, controlled trials representing 16 outcomes in 1,266 subjects met the inclusion criteria. Reductions in blood pressure were approximately 1% and 3% for resting systolic and diastolic blood pressures, respectively. However, random-effects modeling using 5000 bootstrap confidence intervals revealed that neither result was statistically significant (systolic, x-bar (x);+/-SEM=-1+/-2; 95% bootstrap confidence intervals=-2 to 0 mm Hg; diastolic, x+/-SEM=-2+/-1; 95% bootstrap confidence intervals=-3 to 0 mm Hg). The results of this study suggest that short-term exercise does not appear to reduce resting systolic and diastolic blood pressure in children and adolescents. However, a need exists for additional studies, especially in hypertensive children and adolescents.
