The biological variation in maximum aerobic power (V O2max) was examined in four trained females and one trained male. An average of 8-20 repeat VO2max treadmill tests over a 2-4 wk period were performed on each subject (80 total tests). Biological variation (Si) in VO2max was computed as the standard deviation for the VO2max values for each individual,(More)
The validity of the relative percent concept for equating training intensity was investigated using the point of metabolic acidosis (anaerobic threshold) as the criterion variable. Percent oxygen uptake, heart rate and metabolic acidosis were determined at 60, 70, and 80% of max heart rate on a bicycle ergometer test (N=31). At 60 and 70% of max heart rate(More)
PURPOSE/OBJECTIVES To evaluate the effects of 10 weeks of aerobic exercise on depressive and anxiety symptoms and self-esteem of breast cancer survivors. DESIGN Experimental, crossover. SETTING Midwestern university town. SAMPLE Twenty-four breast cancer survivors (mean time following surgery 41.8 months; ranging from 1 to 99 months) recruited via(More)
Exercise-induced changes in muscular and cardiovascular function in pre- and postpubescent children are explained in terms of a "Trigger Hypothesis." This hypothesis predicts that, prepubertally, there will be only small training-induced biological alterations because of the lack of hormonal control. It is suggested, therefore, that emphasis be placed on(More)
The BP distribution of a group of 72 obese adolescents was determined both before and after weight loss. Weight loss was produced by a program of caloric restriction and behavior change alone (n = 26) or with a combination of caloric restriction, behavior change, and exercise (n = 25). It was demonstrated that obese adolescents have a BP distribution that(More)
Thirteen college-age men under-went a treadmill (TM)-graded VO2max exercise test on 1 d and a 24.5-min hydraulic resistive exercise circuit on a following day. Seven exercises were performed in the following order: leg extension, bent-over row, bicep curl, squat, upright row, bench press, and behind-neck press. Each exercise was performed three times with(More)
Fifty-five consecutive female volunteers were evaluated. Linear measurements of the breast and nipple position were determined to fixed points on the chest wall. Volume determination was done by a standard chest-wall casting technique. A highly significant difference was found between left and right breasts in the axilla-to-nipple distance and(More)
