Key result
High-velocity resistance exercise resulted in significantly lower increases in blood pressure, heart rate, and cardiac output compared with high-intensity resistance exercise (p < 0.05).
Why the study?
Does high-velocity resistance exercise reduce acute cardiovascular responses compared to high-intensity resistance exercise in healthy adult men?
Does high-velocity resistance exercise reduce acute cardiovascular responses compared to high-intensity resistance exercise in healthy adult men?
High-velocity resistance exercise elicits lower acute increases in blood pressure, heart rate, and cardiac output compared to high-intensity resistance exercise, suggesting it may be a safer alternative for patients with cardiovascular contraindications.

High-velocity resistance exercise was associated with smaller acute hemodynamic responses in healthy men; leaves open applicability to patients with cardiovascular disease.
The aim of this study is examining the effects of multiple sets of high-velocity resistance exercise (HVRE) on cardiovascular responses. Fifteen healthy adult men participated in two experimental sessions: one comprised three sets of resistance exercise performed against high-intensity resistance exercise (HIRE) at low velocity and the other three sets of HVRE performed against reduced load at high velocity. Blood pressure (BP), heart rate (HR), stroke volume (SV) and cardiac output (CO) during both sessions were evaluated using impedance electrocardiography. The increases in BP, HR and CO were significantly lowered during HVRE compared with HIRE (p < 0.05). In contrast, there was no significant difference in SV between sessions (p > 0.05). This study suggested that the increases in BP and CO during HVRE were lower than those during HIRE although HVRE required performing fast movement. HVRE might be applied to patients for whom HIRE is contraindicated because of cardiovascular diseases.

Miyamoto et al. (2017) studied Healthy adults (n=15). High-velocity resistance exercise (HVRE) vs. High-intensity resistance exercise (HIRE) at low velocity was evaluated on Blood pressure, heart rate, stroke volume, and cardiac output (p=<0.05). High-velocity resistance exercise resulted in significantly lower increases in blood pressure, heart rate, and cardiac output compared with high-intensity resistance exercise (p < 0.05).
