The Effect Of Varying Weightload Intensities On Biceps Curl Technique, Jeffrey C. Gailhouse

Masters Theses

This study described biomechanical deviations from proper biceps curl technique specifically in the shoulder, trunk, body and knee angles, that occurred in response to varying intensities of an individual's 1 RM (repetition maximum). Ten college age males participated in the study. Subjects were required to perform one repetition at 60%, 70%, 80%, 90% and 100% of his 1 RM. The only differentiating factor was the order in which the five intensities were performed. Condition order was randomized to minimize bias. Movement was filmed with a high-speed motion picture camera, digitized and then analyzed with computer software.

The findings indicated that …

The R Value At Vo2 Max During Maximal Graded Exercise Treadmill Tests Of Coronary Artery Diseased And Nondiseased Subjects, Sherry S. Williams

Masters Theses

This study examined the R value at VO2 max during maximal graded treadmill exercise tests to determine if it was a reliable indicator of VO2 max and could therefore be used as a test termination criterion. The subjects in this study were 160 coronary artery diseased (CAD) patients and 170 nondiseased individuals. Data were collected from existing stress test records. The R value was also analyzed to determine if proportions of diseased and nondiseased subjects were the same. The time it took 100 CAD patients to reach VO2 max and exhaustion once R rose above 1.00 was also examined.

A Comparison Of Percent Body Fat Calculated By Three Methods: Hydrostatic Weighing, Skinfolds, And Near Infrared Technique, James W. Hill

Masters Theses

The purpose of this study was to determine the validity of the near infrared technique for assessing body composition. Hydrostatic weighing was used as the criterion measure to which skinfold technique and near infrared technique (as measured by the Futrex-5000) were compared. Two hundred subjects (115 females, 85 males) had their body composition assessed by the three techniques. The intraclass reliability of the Futrex-5000 was measured at r = .997. The Pearson product-moment correlation between hydrostatic weighing and the Futrex-5000 was r = .71 p < .01. The mean percent body fat derived from hydrostatic weighing was 19.3% compared to 21.6% for the Futrex-5000. At test indicated a significant difference between the mean percent body fats calculated by hydrostatic weighing and the Futrex-5000, t(160) = -5.21, p < .01. This study indicated that the Futrex-5000 was not as valid as either skinfold technique or hydrostatic weighing.

Performance Prediction In Track And Field, Ted James Dabbs

Masters Theses

The study investigated the degree to which predicting performance in track and field relates to individual performances of track athletes. Predictive scores were determined for 26 male and 14 female athletes using prediction equations and test procedures developed by Henson, Turner, and Lacourse (1989a; 1989b). Predictive scores were compared to athletes' individual event point scores published in International Amateur Athletic Federation (IAAF) men's and women's multi-event scoring tables ("Scoring Table for Men's," 1962; "Scoring Table for Women's," 1971).

Each subject's height, weight and age were recorded as well as performances on the following tests: vertical jump, standing long jump, five …
