Resistance Exercise May Offer Different Cardio Benefits
Weight training increased blood flow to limbs more than aerobic exercise did,
study finds(HealthDay News) -- Resistance exercise such as weight training affects blood vessels differently than aerobic exercise and
offers other cardiovascular benefits, finds a new study.
Researchers at the Appalachian State University in Boone,
N.C., compared blood vessel (vascular) responses to two types of moderate-intensity workouts: three sets of 10 repetitions
of eight resistance exercises and 30 minutes of aerobic cycling.
There were significant differences in the vascular
responses to the two types of exercises. Resistance exercise produced greater increases in blood flow to the limbs, while
aerobic exercise reduced arterial stiffness, but without an increase in blood flow.
Resistance exercise also led to
a longer-lasting decrease in blood pressure after exercise, compared to aerobic exercise.
"Resistance exercise may
offer greater benefits from the increases in blood flow to active muscles and could be implemented as a companion to an aerobic
training program," wrote study leader Scott R. Collier, of Appalachian State University, and colleagues in a press release.
They said their findings support previous research showing that resistance exercise has unique effects on blood pressure
and limb blood flow.
"The present study indicates that an acute bout of resistance exercise shows many favorable cardiovascular
benefits and should therefore be considered as part of a daily exercise training program," the researchers concluded.
study appears in the November issue of Journal of Strength and Conditioning Research.
