Cardio session after strength workout keeps arteries supple
Strength training & arteries
Study
Of the 33 test subjects, 22 of them did strength training for 8 weeks. Twice a week they trained their most important muscle groups doing the following basic exercises: chest press, curls, seated rows, shoulder press, leg curls, leg press and sit ups. The subjects trained at 80 percent of their 1 RM, an intensity at which they could just manage 7-8 reps.
Eleven of the subjects ran for 20 minutes on a treadmill at 60 percent of their maximal heart rate – before they started the strength training [BRT]. The other eleven did their running after they'd finished the strength training [ART].
The last 11 did nothing at all [SED]. This was the control group.
Just before the training programme started, just after it finished, and once again after 4 weeks of detraining, the researchers measured the stiffness [baPwV] and the elasticity [FMD] of the subjects' arteries.
Triangles = control group; circles = cardio before strength training; squares = cardio after strength training.
Results
Conclusion
There's also another way that strength athletes can keep their arteries healthy. Watch this space.
