Hypothesis
Can isometric exercise be effectively assessed using fast-imaging MRI?
Conclusion
Isometric biceps exercise testing is feasible in an MRI setting and produces a significant hemodynamic response.
Supporting Evidence
- All participants completed the isometric exercise test.
- All data sets were complete.
- Sustained isometric exercise in the MRI scanner produced a marked hemodynamic response.
- Most indices were changed at one minute, while all were changed after two and three minutes.
- The return towards the resting state at recovery was fast.
- There was no evidence of compensatory adaptive hemodynamic mechanisms during the recovery period.
Takeaway
The study shows that doing a bicep exercise while in an MRI machine can help doctors see how your heart and blood vessels respond to exercise.
Methodology
Ten healthy male volunteers performed a sustained isometric biceps exercise test while undergoing MRI.
Participant Demographics
Ten healthy male volunteers aged 24 to 44 years.
