Allometric scaling models of isometric biceps strength and the effects of resistance training
Title
Allometric scaling models of isometric biceps strength and the effects of resistance training.
Creator
Ryan, Eric Dobert., Florida Atlantic University, Zoeller, Robert F.
Abstract/Description
The purpose of this study was to (1) derive gender-specific allometric scaling models using pre-training muscle cross-sectional area (CSA) and body mass (BM) as scaling variables, (2) test model appropriateness using regression diagnostics, and (3) cross-validate the models before and after training. A subset of FAMuSS study data (n = 319, females = 183, males = 136) was randomly split into two groups (A & B). Group A pre-training data for female BM, female CSA, male BM, and male CSA models...

A subset of FAMuSS study data (n = 319, females = 183, males = 136) was randomly split into two groups (A & B). Group A pre-training data for female BM, female CSA, male BM, and male CSA models produced scaling exponents of 1.08, 0.44, 0.63, and 0.68, respectively. The female BM model was deemed inappropriate due to non-normal distribution of residuals. All other models met statistical criteria including normal distribution of residuals. Cross-validation to Group B pre-training data revealed that the models were appropriate, with the possible exception of male CSA model. Twelve weeks of resistance training did not alter the relation between BM, CSA, and muscular strength assessed by allometric scaling.

Comparing the Use of a Business Plan with a Community Intervention Model in a Volunteer Project of a Not-For-Profit Agency.
Creator

Abstract/Description
Health promotion and community intervention models are available for community projects. Project volunteers with business backgrounds may lack knowledge of these models, but be familiar with business plans. This study analyzed a community project using the Planned Approach to Community Health (PATCH) model and a business plan and proposed a new model based on that analysis.

Show moreHealth promotion and community intervention models are available for community projects. Project volunteers with business backgrounds may lack knowledge of these models, but be familiar with business plans. This study analyzed a community project using the Planned Approach to Community Health (PATCH) model and a business plan and proposed a new model based on that analysis. The documented processes and activities of the United Way of Broward County. Florida, Women's Way 2006 Helmets for the Holidays committee were collected, subjectively evaluated, and used as the basis for a new model integrating components of PATCH and a business plan. The significant contribution of the resulting model is its incorporation of a community outreach component into a planning and management model that uses business-comfortable language.

The effect of menopausal status on substrate utilization in younger women during submaximal exercise
Title
The effect of menopausal status on substrate utilization in younger women during submaximal exercise.
Creator
Pittinger, Elizabeth Smith, Zoeller, Robert F., Florida Atlantic University, College of Education, Department of Exercise Science and Health Promotion
Abstract/Description
The purpose of this study was to determine if surgically-induced menopause in younger women affects substrate utilization during submaximal exercise while controlling for other potential confounds. METHODS: Thirteen untrained female subjects (33-50 years old) were recruited: oophorectomized (Group O = 5) and premenopausal controls (Group C = 8). Two separate visits included: body composition and maximal treadmill exercise test; followed by substrate utilization via open-circuit spirometry...

METHODS: Thirteen untrained female subjects (33-50 years old) were recruited: oophorectomized (Group O = 5) and premenopausal controls (Group C = 8). Two separate visits included: body composition and maximal treadmill exercise test; followed by substrate utilization via open-circuit spirometry during 45 minutes of treadmill walking at 50% VO2max. RESULTS: When controlling for multiple variables affecting whole-body substrate utilization (age, VO2max, physical activity, body composition, fasting glucose, menstrual phase and diet), there was no difference in substrate utilization between pre- and postmenopausal women as measured by respiratory exchange ratio (RER) (0.83 ± 0.04 v 0.84 ± 0.03, p=0.47). CONCLUSIONS: Menopausal status does not appear to have an effect on substrate utilization during submaximal exercise in younger women.

Relationships Between Diet and Physical Activity Lifestyle Factors and Body Composition, Waist Circumference, and Body Mass Index in Postmenopausal Women
Title
Relationships Between Diet and Physical Activity Lifestyle Factors and Body Composition, Waist Circumference, and Body Mass Index in Postmenopausal Women.
Creator
Jansen, Mary, Zoeller, Robert F., Florida Atlantic University, College of Education, Department of Exercise Science and Health Promotion
Abstract/Description
PURPOSE: The purpose of this study was to compare relationships between dietary and physical activity (PA) behaviors and body composition and body fat distribution, as measured by percent body fat (BF%), waist-to-height ratio (WHt), waistto- hip ratio (WHp) and body mass index (BMI) in post-menopausal women (Post), with the same relationships in pre-menopausal women (Pre). METHODS: Ninety-two subjects (n = 48 Post; n = 44 Pre) were measured for height, weight, waist and hip circumferences and...

METHODS: Ninety-two subjects (n = 48 Post; n = 44 Pre) were measured for height, weight, waist and hip circumferences and skinfold thicknesses. Dietary content was obtained from a Diet History Questionnaire (DHQ II); PA was estimated from responses to the International Physical Activity Questionnaire (IPAQ). RESULTS: Multiple regression identified no modifiable predictor variables for Pre. Models for Post identified saturated fat grams (SFGs), PA, years postmenopause (YrsPost), and Alcohol (Alc) as predictors of WHt, WHp, BMI and BF%. CONCLUSIONS: PA, SFG and Alc are modifiable variables related to postmenopausal body composition and fat distribution.

Abstract/Description
Glucocorticoid receptor (NR3C1) polymorphisms associate with obesity, muscle strength, and cortisol sensitivity. We examined associations among four NR3C1 polymorphisms and the muscle response to resistance training (RT). European-American adults (n = 602, 23.8±0.4yr) completed a 12 week unilateral arm RT program. Maximum voluntary contraction (MVC) assessed isometric strength (kg) and MRI assessed biceps size (cm^2) preand post-resistance training. Subjects were genotyped for NR3C1 -2722G>A,...

We examined associations among four NR3C1 polymorphisms and the muscle response to resistance training (RT). European-American adults (n = 602, 23.8±0.4yr) completed a 12 week unilateral arm RT program. Maximum voluntary contraction (MVC) assessed isometric strength (kg) and MRI assessed biceps size (cm^2) preand post-resistance training. Subjects were genotyped for NR3C1 -2722G>A, -1887G>A, -1017T>C, and +363A>G. Men carrying the -2722G allele gained less relative MVC (17.3 ±1.2vs33.5±6.1%) (p = 0.010) than AA homozygotes; men with -1887GG gained greater relative MVC than A allele carriers (19.6±1.4vs13.2±2.3%) (p = 0.016). Women carrying the -1017T allele gained greater relative size (18.7±0.5vs16.1±0.9%) (p = 0.016) than CC homozygotes.We found sex-specific NR3C1 associations with the muscle strength and size response to RT. Future studies should investigate whether these associations are partially explained by cortisol’s actions in muscle tissue as they interact with sex differences in cortisol production.
