Does the acute blood pressure response to a single bout of resistance exercise predict chronic blood pressure changes after 12 weeks of resistance training in medicated hypertensive elderly women?
Acute blood pressure responses to a single bout of resistance exercise can predict the chronic blood pressure-lowering effects of a 12-week resistance training program in medicated hypertensive elderly women.
Effect estimate: r = 0.47
p-value: p=0.03
BACKGROUND: A previous study observed that the chronic effects of aerobic training on blood pressure (BP) are related to acute BP responses after a single bout of aerobic exercise. However, whether similar responses are observed with resistance exercise (RE) remains obscure. Thus, this study analysed the relationship between the acute BP responses to a single bout of RE and chronic changes in resting BP after a RE training in medicated hypertensive elderly women. METHODS AND RESULTS: Twenty medicated hypertensive women participated in the study. They underwent an acute RE bout where BP and heart rate (HR) were obtained at rest and for 60 min after the RE. Subsequently, the participants underwent a progressive RE training for 12 weeks at 60-80% of maximal strength test. Resting BP and HR were also obtained after the RE training. The chronic decreases in systolic and diastolic BP were significantly greater in the participants who experienced acutely decreased systolic and diastolic BP, respectively (P<0·05). The changes in systolic BP after acute RE were correlated with the chronic changes in resting systolic BP after RE training (r = 0·47; P = 0·03). Similar correlations between acute and chronic responses were also observed for diastolic BP (r = 0·70; P = 0·01), mean BP (r = 0·58; P = 0·01), HR (r = 0·73; P<0·01) and RPP (r = 0·52; P = 0·01). CONCLUSION: Similar to previously work involving aerobic exercise, BP responses to a single bout of RE are strongly related to chronic effects of RE training on BP in medicated hypertensive elderly women.
Moreira et al. (Thu,) conducted a observational in Hypertension (n=20). Resistance exercise (RE) training was evaluated on Correlation between acute changes in systolic BP after a single RE bout and chronic changes in resting systolic BP after RE training (r = 0.47, p=0.03). Acute systolic blood pressure changes after a single bout of resistance exercise correlated with chronic changes in resting systolic blood pressure after 12 weeks of training (r=0.47; P=0.03).
