ABSTRACT:
The metabolic cost of weight training, especially advanced programs, has been poorly researched and is poorly understood. This study describes the metabolic, heart rate, and blood pressure responses of three weight lifters during a week of preparation phase training. Oxygen uptake (VO2) was measured with a Beckman MC, resting heart rate (RHR) by palpitation, and resting blood pressure (RBP) by auscultation. Twelve workouts were performed during the week. The average caloric expenditure (L O2 x 5 plus Kcal) was 9.4 Kcal.min-1 and 3918 Kcal/wk. Larger muscle mass exercises (i.e., squats, pulls, etc.) averaged 11.5 Kcal.min-1, and small muscle mass exercises (i.e., bench press, sit-ups, etc.) averaged 6.8 Kcal.min-1. Resting HR and RBP were largely unaffected. It appears that the volume and intensity of this type of training is sufficient to elicit beneficial alterations in body composition, serum lipids and possible cardiovascular function.
