- The effect of competition on men’s sexual behavior.
- Creator
- Gorelik, Gregory, Bjorklund, David F., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Psychology
- Abstract/Description
-
Evidence in humans suggests that men are especially competitive with other men over resources and, if successful, are valued as attractive mating prospects by women. Previous studies also show that men experience an increase in testosterone following a win and a decrease in testosterone following a loss. If an increase in testosterone following a victory is an evolved physiological response aimed at readying a man for an increase in mating opportunities, then experimentally manipulating...
Show moreEvidence in humans suggests that men are especially competitive with other men over resources and, if successful, are valued as attractive mating prospects by women. Previous studies also show that men experience an increase in testosterone following a win and a decrease in testosterone following a loss. If an increase in testosterone following a victory is an evolved physiological response aimed at readying a man for an increase in mating opportunities, then experimentally manipulating competitive outcomes should differentially affect men’s sex-drive. One-hundred thirteen men were randomly assigned to experience a win, a loss, or no competitive feedback. Participants’ sex-drive was gauged by their responses to photographs of women of differential attractiveness. Results showed that only single men exhibited a higher sex-drive in the winning condition, followed by the control and losing conditions, respectively. Limitations and practical applications to decreasing instances of rape and sexual coercion are discussed.

- 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.

- Creator
- Goldstein, Erica R., College of Education, Department of Exercise Science and Health Promotion
- Abstract/Description
-
The purpose of this study was to determine the acute effects of caffeine supplementation on strength and muscular endurance in resistance-trained women. In a randomized manner, 15 women consumed caffeine (6 mg/kg) or placebo (PL) seven days apart. Sixty minutes following supplementation, participants performed a one repetition maximum (1RM) barbell bench press test and repetitions to failure at 60% of 1RM. Heart rate and blood pressure were assessed at rest, 60 minutes post-consumption, and...
Show moreThe purpose of this study was to determine the acute effects of caffeine supplementation on strength and muscular endurance in resistance-trained women. In a randomized manner, 15 women consumed caffeine (6 mg/kg) or placebo (PL) seven days apart. Sixty minutes following supplementation, participants performed a one repetition maximum (1RM) barbell bench press test and repetitions to failure at 60% of 1RM. Heart rate and blood pressure were assessed at rest, 60 minutes post-consumption, and immediately following completion of repetitions to failure. Repeated measures ANOVA indicated a significantly greater bench press maximum with caffeine (p<0.05) (52.9 « 11.1 kg vs. 52.1 « 11.7 kg) with no significant differences between conditions in 60% 1RM repetitions (p=0.81). Systolic blood pressure was significantly greater post-exercise, with caffeine (p<0.05) (116.8 « 5.3 mmHg vs. 112.9 « 4.9 mmHg). Our findings indicate a moderate dose of caffeine may be sufficient for enhancing strength performance in resistance-trained women.

- Relationship Between Anthropometric Measurements and Average Concentric Velocity In The Back Squat.
- Creator
- Cooke, Daniel M., Zourdos, Michael C., Florida Atlantic University, College of Education, Department of Exercise Science and Health Promotion
- Abstract/Description
-
The purpose of the present study was to investigate if any relationship exists between anthropometric measurements with average concentric velocity (ACV) at various intensities in the back squat and the number of repetitions able to be performed during a set to volitional fatigue at 70% of one-repetition maximum (1RM). It was hypothesised that short femurs and total height would be related to slower ACVs and lower total number of repetitions performed. 58 resistance trained subjects were...

It was hypothesised that short femurs and total height would be related to slower ACVs and lower total number of repetitions performed. 58 resistance trained subjects were recruited and attended one day of data collection. Subjects performed 1RM testing of the back squat followed by two single repetition sets at 30-90% of 1RM and a 70% of 1RM set to fatigue. There was no significant correlation between femur length and height with ACV at any intensity (p>0.05). A significant negative correlation existed between both height (r=-0.39, p=0.003) and femur length (r=-0.31, p=0.018) with total number of repetitions performed.

- Abstract/Description
-
The Anterior Cruciate Ligament (ACL) resists excessive anterior translation and internal rotation of the tibia during athletic activities and stabilizes the knee. In the US, annually, over 200,000 cases of ACL disruption are reported. The impact on the quality of life of the subject and its cost to healthcare is tremendous. The objectives of this study were to determine any significant associations between the size of the tibial eminence and ACL injury and to develop a finite element model...
Show moreThe Anterior Cruciate Ligament (ACL) resists excessive anterior translation and internal rotation of the tibia during athletic activities and stabilizes the knee. In the US, annually, over 200,000 cases of ACL disruption are reported. The impact on the quality of life of the subject and its cost to healthcare is tremendous. The objectives of this study were to determine any significant associations between the size of the tibial eminence and ACL injury and to develop a finite element model for structural analysis. The results suggest that the size of the tibial eminence plays a role in loading the ACL and is therefore a risk factor. In addition to the epidemiological analysis, a finite element model of the knee was developed that with added modifications can be used for complex knee loading situations. The results in this thesis may be used to develop strategies for ACL injury prevention and rehabilitation.

Show moreDietary supplement use influences and effects of gender and grade by 184 adolescent athletes in ten Broward County high schools, grades nine through twelve, were examined in this study. A survey (Survey to Predict Adolescent Athletes Dietary Supplement Use) based on the Theory of Reasoned Action was used to predict how the supplement group users/non-users demonstrated a relationship with the theory components. Results yielded supplement group differences with regard to gender and grade. Regarding behavioral intention, supplement group users (current, past, or experimental) had a stronger intention to use supplements in the future than did non-users. Main effects emerged with male athletes having a stronger intention to use supplements than did females. The health risks that accompany supplement products show evidence of the need for health educators to understand more about the issue in order to establish intervention strategies.
