Effects of high-intensity strength training on cardiovascular function
Key result
High-intensity strength training fails to improve cardiovascular function or VO2max versus no training.
- n=23
Why the study?
The effects of high-intensity, variable-resistance strength training on cardiovascular function in healthy, untrained males were unclear.
Does 16 weeks of high-intensity strength training improve cardiovascular function in healthy, untrained males?
Comparison
16 weeks high-intensity Nautilus strength training vs no training
Design
Controlled cohort study
Follow-up
16 weeks

Implication
High-intensity strength training should not be expected to improve cardiovascular function; leaves open effects of longer durations or combined regimens.
Structured PICO
Does 16 weeks of high-intensity strength training improve cardiovascular function in healthy, untrained males?
P
Population
23 healthy, untrained males (mean age 47.5 years) evaluated for the effects of 16 weeks of high-intensity strength training on cardiovascular function.
I
Intervention
16 weeks of high-intensity, variable-resistance, Nautilus strength training
C
Comparator
No training (underwent same evaluation procedures)
O
Outcome
Maximal oxygen uptake (VO2max) and cardiac output during submaximal exercisesurrogate
High-intensity strength training over 16 weeks does not produce adaptive improvements in cardiovascular function in healthy, untrained males.
Cite This Study
Hurley et al. (1984) studied Healthy, untrained (n=23). High-intensity, variable-resistance strength training vs. No training was evaluated on Maximal oxygen uptake (VO2max) and cardiac output during submaximal exercise. High-intensity, variable-resistance strength training for 16 weeks produced no adaptive improvement in cardiovascular function, including maximal oxygen uptake and hemodynamic responses.
