The extent of muscular strength and muscular size in 20 female bodybuilders and 20 non-strength trained females was studied. Body composition and segment volumes and related anthropometric measurements data were obtained along with chest press and knee extension One Repetition Maximum (IRM) and 25 Repitition Maximum (25RM) values. No group differences were present in age, height, weight and segment volumes. The bodybuilders had a lower percent body fat, greater lean body weight (LBW) and larger muscles compared to the non-strength trained females.

The purpose of the study was to provide descriptive information on nutritional profiles and body weight (BW) patterns of 6 competitive female body builders (x age = 27) before, during and after a competition. Precompetition (-28 to -26 d); (-9 to -7 d), competition (-2 to 0 d) and post competition (+1 to +3 d); (+26 to +28 d) 3-d diet and BW records were recorded. Diet records were analyzed using the Nutripractor 6000 nutrient analysis system. Two weeks precompetition, percent body fat was estimated using skinfold measurements. All subjects completed a 60-item fixed choice and open-ended questionnaire concerning menstrual characteristics, training and dietary practices. A subgroup (n=2) agreed to collect daily urine samples for one month prior and one month after competition. Samples were analyzed for estradiol (E2) and progesterone (P4). / Master of Science

To obtain descriptive information concerning female bodybuilders and women who weight train, a questionnaire concerning training regimes, menstrual history and dieting strategies was developed and administered with the EDI included as part of the questionnaire. Factors assessed included: incidence of menstrual irregularity, scores on the Eating Disorder Inventory (EDI), prevalence of behaviors associated with eating disorders, and mean body fat. Subjects were between the ages of 18 and 35 and included individuals from Personal Health Classes at Virginia Tech, the Virginia Tech Weight Lifting Club, and Goad's Gym in Blacksburg, Virginia. Subjects were classified by activity (weight lifters versus controls), involvement (high, moderate and low) and competition (noncompetitive and competitive). Chi-square analysis indicated that there was no difference in incidence rates of menstrual irregularity between weight lifters (WLs) and controls (Cs); however, the rates of both groups were higher than the general population. Although there was no difference in menstrual function of involvement groups, 50% of the competitors, significantly more than non-competitors, were classified as oligomenorrheic or amenorrheic. All subject groups had mean scores approaching anorexic patient norms on the EDI Bulimia and Maturity Fears subscales. WLs were significantly higher on Drive for Thinness than Cs and more WLs had subscale scores higher than the mean scores presented for anorexics. Additionally, significantly more WLs reported uncontrollable urges to eat, fear of fat, and history of anorexia. Mean %BF of the WLs was 20.18% with competitors being significantly leaner than non-competitors. The high degree of menstrual dysfunction in both WLs and Cs is confusing; yet, the 27% incidence of oligomenorrhea and amenorrhea in WLs is much higher than the rates documented for the general population. The high Drive for Thinness and incidence of negative eating behaviors indicate that the prevalence of eating disorders in this population may progress as this relatively new sport evolves and competitive participation increases. / M.S.

This study compared bone mineral index (BMI, gm/cm²) of the femur, spine, and radius, measured by photon absorptiometry in various groups of eumenorrheic female athletes. The sample included body builders (11), swimmers (13), runners (5 collegiate, 11 recreational), and inactive controls (18) averaging 25 years of age, ranging from 17 to 38 years. Lumbar vertebral BMI for body builders (1.40 gm/cm²) was significantly (p ≤ 0.05) greater than controls (1.25 gm/cm²). The body builders' femoral neck BMI (1.09 gm/cm²) was significantly greater than swimmers (0.97 gm/cm², recreational runners and controls (0.95 gm/cm²). Years of exercise history and calcium consumption were not significant predictors of BMI. Correlation coefficients between fat-free body and all BMI sites were significant and more closely related to bone mineral than other variables (weight, height, weight/height²). Correlation coefficients for proximal and distal radius BMI and femoral and spine BMI were significant, the distal radius having higher association.

Smegenų kraujotakos autoreguliacija (SKAR) – viena svarbiausių gyvybinių organizmo funkcijų, t.y. smegenų savybė moduliuoti apsirūpinimą krauju, išlaikant nekintamą kraujotaką,skirtingo smegenų perfuzinio spaudimo sąlygomis (Paulson et al., 1990). Perfuzinis spaudimas,įveikiantis išorinį pasipriešinimą (vidinį kaukolės slėgį ) ir vidinį (arteriolių sienelių tonusą,reguliuojamą vazomotorų) palaiko smegenų kraujotaką (Steiner et al., 2003b). Sveikame organizme garantuojamas smegenų kraujotakos pastovumas ir regioninis pasiskirstymas pagal metabolinius- funkcinius poreikius (Sato et al., 2009). Fizinio ar emocinio krūvio metu pakinta įprastinė organizmo sistemų veikla. Fizinis krūvis paveikia kiekvieną kardiovaskulinės sistemos komponentą. Fizinio krūvio metu padidėja aktyviai dirbančių raumenų metabolinis poreikis, sukeliama lokali vazodilatacija, kuri garantuoja adekvačią kraujo perfuziją ir sukelia bendro periferinio pasipriešinimo sumažėjimą (Sprangers et al., 1991; Brys et al., 2003), tuo pat metu padidėja sistolinis širdies tūris ir širdies susitraukimų dažnis (Brys et al., 2003; Duncker and Bache, 2008; Laughlin et al., 2011). Ilgalaikės treniruotės veikia kraujo spaudimą dėl lėtinio autonominės kontrolės mechanizmų poveikio ir kraujagyslių remodeliavimo (Pescatello et al., 2004b). Pasipriešinimo pratimai padidina periferinį kraujagyslių pasipriešinimą ir kairiojo skilvelio pokrūvį (Leddy and Izzo, 2009). Fizinio krūvio pradžioje būna smegenų kraujotakos padidėjimas...

Perfusion pressure maintains cerebral blood flow by overcoming external (i.e. intracranial pressure) as well as internal resistance (i.e. vasomotor regulated tone of the arteriolar wall) (Steiner et al., 2003b). In healthy body, constant cerebral blood flow and regional distribution is maintained in accordance tometabolic and functional needs (Sato et al., 2009). Physical and emotional stress alters regular activity of organism. Physical exercise affects every component of cardiovascular system. Metabolic demand of actively exercising muscles increases during physical exercise; local vasodilatation develops, thus adequate blood perfusion is maintained and total peripheral resistance decreases (Sprangers et al., 1991; Brys et al., 2003). Meanwhile, systolic blood pressure and heart rate increases (Brys et al., 2003; Duncker and Bache, 2008; Laughlin et al., 2011). Due to long-term effect of autonomous control mechanisms and blood vessel remodeling, long-term physical training affects blood pressure (Pescatello et al., 2004b). Resistance exercises increase peripheral resistance of blood vessels and left ventricle afterload (Leddy and Izzo, 2009). At the onset of exercise, there is... [to full text]

The effects of two hypocaloric diets on body weight (BW), percent body fat (%BF), lean body mass (LBM) and static muscular endurance were studied in college aged experienced male weightlifters for 7 days. Nineteen (X age = 20.6) volunteers were randomly assigned to one of three groups: control (n=5), High Protein/Moderate Carbohydrate - HP/MC (n=7) or Moderate Protein/High Carbohydrate - MP/HC (n=7). The two hypocaloric groups consumed 18 kcal/kg body weight for 7 days. The HP/MC group's diet contained 1.6 g/kg body weight/day of protein while the MP/HC group consumed 0.8 g/kg body weight/day of protein. Fat content of both diets was approximately equal so that carbohydrate content varied inversely with protein content. The control group was asked to follow a weight maintenance diet. All groups followed a similar supervised weight training regimen approximately 2 hours per day, six of the seven days of the study. Analysis of variance revealed that weight loss for the control group was not significant over the seven day experiment but that the two experimental groups showed a similar significant decrease in body weight of 3.6 kg for the HP/MC group and 4.0 kg for the MP/HC group. %BF of all subjects was significantly lower over the 7 day study using both skinfold measurements and hydrostatic weighing but there was no significant difference between the groups. LBM losses calculated from skinfold measurements were seen over time for all subjects and a significant interaction showed the 2 experimental groups to lose significantly more LBM over the 7 day study. LBM determined from hydrostatic weighing produced losses as well, but no differences were noted between the groups. All groups experienced quadricep endurance decrements over the 7 day study, but did not differ from each other. No significant changes were found for bicep endurance. It was concluded that neither the HP/MC diet nor the MP/HC diet was effective for maintaining LBM or quadricep endurance. However, both diets did produce significant losses in BW and %BF over the week long study. / M.S.

The purpose of this research is to explain anabolic steroid use among non-competitive male bodybuilders. Two theories of deviant behavior are used in this research: rational choice theory and social learning theory. This thesis tests these theories on a sample of 50 males from fitness centers and gymnasiums. The results are interpreted in light of their implications for future research on the factors that encourage steroid use and other deviant behavior. / Master of Science
