- Comparison of Anthropometric Measures of Competitive Bodybuilders to Judges' Scores and a Comparison of Judges' ScoresGaines, Rodney P. (Virginia Tech, 2001-08-08)This research compared physical characteristics of bodybuilders to judges' rankings, and compared the judges' rankings across three levels of judges: Elite, Trained, and Untrained. Twenty-nine male and nine female bodybuilding athletes consented to anthropometric and circumference measurements. The independent variables in this study were bodyfat, fat-free weight, and proportionality of muscle. Three groups of judges ranked male and female athletes in the Open, Novice, Collegiate, and Masters divisions. The measurements of proportionality of muscle, bodyfat, girths, and fat-free weight were analyzed using simple and multiple regression. The judges' rankings in each class were compared using reliability coefficients, correlation, repeated measures analysis of variance, and the generalized theory for inter-rater reliability. There were significant correlations between the Elite judges' rankings and bodyfat in the Men's Open lightweight class. The Trained and Elite judges' rankings were significantly correlated with bodyfat in the Women's Novice class. Fat-free weight was significantly correlated with the Untrained and Elite judges' rankings in the Women's Novice division. Proportionality of muscle was significantly correlated with the Elite and Trained judges' rankings in the Men's Open lightweight class. Elite and Trained judges' rankings were significantly correlated with bodyfat and proportionality of muscle. All three groups of judges' were significantly correlated with the Overall rankings. The Trained judges' rankings were more correlated and more reliable with the Elite judges. The inter-rater reliability scores were higher for the Elite and Trained judges than for the Untrained judges. When fat-free weight was substituted for body weight in the calculation of proportionality of muscle, prediction of ranking was enhanced. The education session led to a significant disparity in judges' rankings between Trained and Untrained judges. Bodyfat appears to be a better selection variable when comparing physical measurements to judges' rankings in women. Proportionality of muscle is a better selection variable in predicting judges' rankings in men. Prediction models developed from this investigation need further testing.
- The effects of velocity specific isokinetic training on strength, hypertrophy, and cross educationGaines, Rodney P. (Virginia Tech, 1996-05-05)This study examined the effects of six weeks of velocity specific isokinetic training on peak torque (PT), and the estimated cross-sectional area of the upper arm (AG) in the trained. Thirty volunteers (M=15, F=15) were randomly assigned to an experimental, slow velocity group (S), 60 degrees-per-second (n=9; 25.4±..6.5yr), a fast velocity group (F), 450 degrees-per-second (n=ll, 23.7 ±..S.4yr), or control group (C) (n=10, 26 ± 3.2yr). One limb was randomly selected for isokinetic training (3 d/wk-elbow flexion) using a Biodex System 2 isokinetic dynamometer. The contralateral limb served as a control and as the basis for measurements measure of cross education (CE). Both experimental conditions (S) and (F) were assigned equal training workloads, calcu1ated from an isokinetic pre-test. Pre- and post-tests (PT) were recorded for both limbs at the training velocities of 60 and 450 degrees-per-second, as well as the velocity of 210 degrees-per-second. Pre and post-test (AG's) were measured on the training limb. The (S) condition was significantly different in strength gains from the control at 60 degrees-per-second, but not different from the fast velocity group in the trained limb. The (F) condition was significantly different in strength gains from the control at 450 degrees-per-second, but not different from the slow velocity group in the the trained limb. The conditions were not significantly different from each other in the trained limb at the test velocity of 210 degrees-per-second. The three conditions significantly different from each at the test velocity of 60 degrees-per-second in the trained limb. The conditions did not differ in strength at velocities of 210 and 450 degrees-per-second in the trained limb. The conditions did not differ in the cross-sectional area of the upper arm in the trained limb. The (S) and (F) training conditions improved (PT) by 12.36% and 18.84% at their respective training velocities of 60 and 450 degrees-per-second. These improvements were significantly (p<.05) larger than (C). The (S) and (F) training conditions also increased (PT) by 11.56% and 11.24% at the non-training velocity of 210 degrees-per-second (p<.05). Significant 10.77% (p<.05) improvement in (AG) was recorded in the (S) condition. No changes in (PT) were recorded in the contralateral limb within the three conditions. These data support the concept of limited (S) and (F) hi-directional (PT) overflow and (S) velocity hypertrophy enhancement. The presence of cross education (CE) was not supported by this investigation.
- A Grounded Theory Approach to Studying Dislocated Workers' Decisions and Perceptions Regarding Retraining and Reemployment Programs and ServicesBurnett, Richard Gregory (Virginia Tech, 2003-12-01)The purpose of this study was to investigate the decisions and perceptions of Lane Company's dislocated workforce regarding retraining and reemployment programs funded by the Minnie and B.B. Lane Foundation (MBL Foundation), Virginia Employment Commission (VEC), both organizations, or neither organization. Thirteen Lane Company dislocated workers were interviewed utilizing an open-ended questionnaire. The results of this study indicated that the retraining and reemployment needs of Lane Company's dislocated workers were accommodated. However, to accommodate those needs, two organizations were required, the VEC and the MBL Foundation. The VEC was instituted by the federal and state government to provide retraining and reemployment services to dislocated workers via the Trade Act of 1974. The MBL Foundation, a nonprofit organization, was established to provide funding for retraining and reemployment programs to Lane Company's dislocated workforce. Many dislocated workers approached the VEC to apply for retraining, but found that the funding was insufficient or the retraining program they desired was not approved under the Trade Act. The dislocated workers perceived the MBL Foundation as an alternative for supplementary retraining funds and programs they preferred. An approach to provide for the needs of dislocated workers is to revise and appropriate additional funds to the Trade Act. Moreover, the manner in which Lane Company's dislocated workers were accommodated may possibly stand as a model for meeting the needs of other dislocated workers.
