This study compared three indirect calorimetry determinations, as kcals/minute, over three consecutive days on 28 healthy, sedentary women of varying body composition. No significant within-individual variation for VO2, CO2, respiratory quotient (RQ), or Kcals/minute was found among the three days. A low coefficient of variation (3.4 +/- 3%) and a relatively small standard deviation in mean Kcals/day (1383 +/- 214) suggests possibly one or only a few measures are necessary for predicting resting metabolic rate (RMR) within a range applicable for clinical use. There were strong correlations of body weight and body composition variables (fat and LBM) with RMR. Knowing both LBM and fat mass increased the ability to predict RMR significantly over the prediction with either variable alone. The Harris Benedict equation over-predicted RMR by 11.1% compared to RMR measured by indirect calorimetry. When equations are based on body weight, rather than LBM, metabolic rate may be over-predicted in obese populations.

The American College of Sports Medicine (ACSM) currently recommends 1 set of 8 - 12 repetitions as the minimal dose of resistance training (RT) required to achieve the health and fitness benefits gained from RT. Yet, certain benefits derived from resistance training are not mentioned by the ACSM. An increase in basal metabolic rate (BMR) is a possible health benefit derived from RT. However, no previous studies have examined the effect of the ACSM's current resistance training recommendations on BMR. Therefore, the purpose of this study was to determine if this low level of RT could increase BMR in currently active older men. Sixteen subjects were assigned to either a training group or control group for 10 weeks of training. The training group continued their current aerobic activity while adding 1 set of RT 2x/week as recommended by the ACSM. The control group continued their aerobic activity with no modifications. Measurements of strength, fat free mass (FFM), and BMR were made pre- and posttraining. The training group showed an increase in strength (P<0.05) while the control group did not change. The training and control groups showed no change in FFM or BMR (P<0.05). The strength increases reported in the current study were of expected values while FFM and BMR have not been previously examined with this protocol. It was concluded that 10 weeks of RT using 1 set of 8 - 12 repetitions does not increase BMR in currently active older men. / School of Physical Education

The purpose of this thesis was to monitor body composition and energy expenditure changes during weight loss in subjects encouraged to maintain a diet equal to 90% of resting energy expenditure (REE). Over six months, 69 female subjects had REE measured at baseline and weeks 13 and 25 with fortnightly body composition measurements. Subjects lost significant total body mass (17.2 lb) and fat mass (16.7 lb) (p≤.000). Fat-free mass remained stable during the six month period. REE was significantly higher at baseline (1701.1 kcal) than weeks 13 (1576.3 kcal) and 25 (1579.4) (p≤.000); REE at weeks 13 and 25 were similar (p≥.05). Predicted REE at weeks 13 (1671.3 ± 254.7 kcal) and 25 (1658.5 ± 252.4 kcal), compared to measured REE, was significantly lower, 1576.3 kcal and 1579.4 kcal, respectively (p≤.000). Results of this study illustrate that individuals can lose significant amounts of total body mass while preserving fat-free mass and that during active weight loss, there is a metabolic adaptation to reduced caloric intake. / Department of Family and Consumer Sciences
