Resistance training and the blood lactate response to resistance exercise in women
This study examined the effect of resistance training on blood lactate (BL), heart rate (HR), and rating of perceived exertion (RPE) responses to an exhaustive set of squats in 7 college-age women. Baseline testing consisted of a dual set of squats at 70 and 50% of 1-RM performed to exhaustion. Immediate postexercise BL response was elevated 6.5-fold above baseline values while HR exceeded 90% of age-predicted max. After 10 wks of resistance training, the dependent variables were assessed at Post 1 and Post 2 testing sessions. At Post 1, subjects performed a nonexhaustive set of squats using the same workload and number of repetitions completed during baseline testing. At Post 2 they performed an exhaustive set of squats at 70 and 50% of posttraining 1-RM. Immediate postexercise BL was reduced at Post 1 when compared to baseline BL. Post-2 BL was similar to baseline BL and significantly greater than Post-1 BL. Resistance training also lowered the RPE response to resistance exercise at Post 1 (p ≤ 0.01), but Post-2 RPE did not differ from baseline values. The HR response to resistance exercise was not altered by resistance training. © 1997 National Strength & Conditioning Association.
