Effects Of Short-Term, High-Force Resistance Training On High-Intensity Exercise Capacity., Patrick Abi Nader

Electronic Theses and Dissertations

The purpose of this study was to assess the effects of short-term high-intensity resistance training on time to exhaustion at maximal aerobic output. It was hypothesized that 2 weeks of training will induce improvements in performance at maximal aerobic output. Eighteen subjects participated in this study. Subjects were assigned to a control (n=8) or resistance training (n=10) groups. The resistance training group participated in 5 sessions of strength training over a period of 2 weeks on the leg press device. Both groups participated in pre and post intervention testing. After the intervention strength in the training group significantly increased (p=.00). …

Type Of Encouragement Influences Peak Muscle Force In College-Age Women, Ruth M. Amagliani, John K. Petrella, Alan P. Jung

International Journal of Exercise Science

Purpose: To investigate if the type of encouragement during a maximal voluntary isometric contraction (MVIC) had an influence on peak muscle force in strength-trained versus untrained collegiate women. Methods: Eleven strength-trained (20.4 + 1 yr) and twelve untrained (20.8 + 1 yr) women participated in three, five-second MVICs of seated knee extension. The three trials consisted of verbal only encouragement, verbal + visual encouragement, and verbal + pain avoidance encouragement. In all three trials, the participants received the same verbal encouragement. Trials were counterbalanced to minimize any possible order effects. A repeated measure ANOVA was used to analyze data. Any …

The Effect Of Resistance Training On Strength And Total Physical Activity In Postpartum Females, Tiffany Kaye Hinman

Theses and Dissertations

The purpose of this study was to compare strength and physical activity (PA) changes in postpartum women randomly assigned to either a four-month progressive resistance training (RT) program or a four month flexibility program. Sixty healthy women between six weeks and eight months postpartum initiated the study and 43 completed the entire study. The women tended to be overweight, were all non-smokers, and most were breastfeeding (97%) at the beginning of the study. Both groups (RT and flexibility) completed training exercises twice weekly. Both groups improved in all measures of strength (RT group: leg press, P < 0.001; bench press, P < 0.001; curl-ups, P < 0.001. Flexibility group: leg press, P = 0.009; bench press, P < 0.001; curl-ups, P = 0.005); however, the RT group had higher strength gains compared to the flexibility group over time (leg press, P < 0.005; bench press, P < 0.001; curl-ups, P < 0.007). In addition, both groups increased in low back flexibility but the group*period interaction did not reach significance (P = 0.096). Light-intensity PA increased in the RT group but not the flexibility group (P < 0.05). A group*period interaction was significant for light-intensity PA time (P = 0.031) and borderline significant for sedentary time (P = 0.054). However, controlling for the number of months postpartum and weight gain during the previous pregnancy resulted in a significant interaction for sedentary time (P < 0.05). No changes were found in moderate, vigorous, or moderate to vigorous PA within or between groups over time. In conclusion, twice-weekly RT increases strength and is associated with improvements in several PA outcomes in postpartum women; however, the mechanisms for this are unclear. The training sessions and/or increased spontaneous activity may have contributed.

Impact Of Resistance Training On Balance And Gait In Multiple Sclerosis, Mary Filipi, M. Patricia Leuschen, Jessie M. Huisinga, Lorene Schmaderer, Jeanna Vogel, Daryl Kucera, Nikolaos Stergiou

Journal Articles

Multiple sclerosis (MS) is an incurable neurodegenerative disease whose symptoms are only partially relieved by pharmaceutical intervention. Disability due to this disease process can impede activities of daily living and decrease quality of life, both for MS patients and for their care partners and families. A nonrandomized, nonblinded prospective cohort study of 45 patients with MS was undertaken to investigate the impact of an exercise program emphasizing resistance training on balance and gait. This article presents data for the first 33 participants to complete the study protocol. The exercise program consisted of twice-weekly 50-minute sessions for 6 months. At 3 …

Caffeine Does Not Augment Markers Of Muscle Damage Or Leukocytosis Following Resistance Exercise, Marco Machado, Alexander J. Koch, Jeffrey Willardson, Frederico C. Dos Santos, Victor M. Curty, Lucan N. Pereira

Faculty Research and Creative Activity

The purpose of this study was to evaluate the effects of caffeine ingestion before a resistance exercise session on markers of muscle damage (CK, LDH, ALT, AST) and leukocyte levels. Methods: Fifteen soccer athletes completed two resistance exercise sessions that differed only in the ingestion of caffeine or a placebo preworkout. Results: CK concentration increased significantly following the caffeine session (415.8 ± 62.8 to 542.0 ± 73.5) and the placebo session (411.5 ± 43.3 to 545.8 ± 59.9), with no significant differences between sessions. Similarly, LDH concentration increased significantly following the caffeine session (377.5 ± 18.0 to 580.5 ± 36.1) …

Effect Of Different Resistance Exercise Repetition Velocities On Excess Post-Exercise Oxygen Consumption And Energetic Expenditure, Ana Critine Barreto, Alex Souto Maior, Pedro Menzes, Jeffrey Willardson, Antonio Jose Silva, Victor Machado Reis, Roberto Simão, Jefferson Novaes

Faculty Research and Creative Activity

The excess post-exercise oxygen consumption (EPOC) consists of the excess oxygen consumed above a resting state following exercise. Performance of resistance exercise can significantly disrupt the body’s homeostasis, with the EPOC being dependent on the specific combination of prescriptive variables. Presently, the effects of different repetition velocities on VO2 and caloric expenditure during and following resistance exercise bouts have not been completely elucidated. Objective: To examine the effect of different repetition velocities on EPOC and total energetic expenditure during and following resistance exercise bouts. Methods: Twenty women (34.6 ± 5.5 years; 159 ± 4.1 cm; 55.1 ± 3.4 kg; 24±2.5 …

Exercise-Induced Alterations In Melanocortin Receptor Expression And Inflammation, Tara Michelle Henagan

LSU Doctoral Dissertations

Inflammatory cytokines play a significant role in the pathogenesis of obesity-related diseases and have been implicated as integral factors in both early and late phases of atherosclerosis. Lifestyle modifications such as increasing physical activity and making dietary changes to induce weight loss are part of the primary prescription for the treatment of metabolic syndrome. Additionally, physical activity has been implicated as a potentially effective regimen for the control of inflammation, yet little is known about the anti-inflammatory mechanistic alterations induced by physical activity.

Exercise training causes acute changes in inflammation immediately post exercise, evidenced by upregulation of inflammatory cytokines and …
