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

Jeffrey Willardson

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 …

Effect Of Surface Stability On Core Muscle Activity For Dynamic Resistance Exercises, Jeffrey Willardson, Fabio E. Fontana, Eadric Bressel

Jeffrey Willardson

To compare core muscle activity during resistance exercises performed on stable ground vs. the BOSU Balance Trainer. Methods: Twelve trained men performed the back squat, dead lift, overhead press, and curl lifts. The activity of the rectus abdominis, external oblique abdominis, transversus abdominis/internal oblique abdominis, and erector spinae muscles was assessed. Subjects performed each lift under three separate conditions including standing on stable ground with 50% of a 1-RM, standing on a BOSU Balance Trainer with 50% of a 1-RM, and standing on stable ground with 75% of a 1-RM. Results: Significant differences were noted between the stable 75% of …

An Evaluation Of Endurance And Combined Endurance And Resistance Training On Fitness And C-Reactive Protein, Laura A. Daray

LSU Master's Theses

PURPOSE: This study was designed to determine whether endurance or endurance + resistance training would influence circulating C-reactive protein (CRP) levels and if these changes are related to alterations in aerobic fitness and/or body composition. METHODS: Fifty eight healthy young adults aged 18-24 yrs (78% female) were assigned to one of three groups: 1) endurance training (E) (n=18), 2) endurance + resistance training (ER) (n=11), or 3) active control (AC) (n=29). The E group completed 15 weeks of endurance training for either a half marathon (n=6) or full marathon (n=12). The ER group performed 15 weeks of periodized resistance training …

A Comparison Of Linear And Daily Undulating Periodizied Strength Training Programs., Andrew Morrow Caldwell

Electronic Theses and Dissertations

The purpose of this study is to compare linear periodized (LP) and daily undulating (DUP) periodized strength training programs, and determine if either method of periodization elicits superior gains in 1 Repetitions maximums (1RM) for back squat (BS) and bench press (BP) (core exercises). Nineteen subjects (n=19) underwent a 6-week resistance-training (RT) program. Participants performed both BS and BP two day a week. The LP group linearly increased intensity while decreasing volume. While the DUP group daily changed intensity and volume. Total volume for both BS and BP were equal for both LP and DUP. Both BP and BS increased …

Effects Of High-Load Eccentric Exercise Training On Rat Soleus Muscle Myofibrillar Disruption Following One-Week Of Hindlimb Suspension Unloading And Subsequent Reloading, Rhonda Dianne Prisby

LSU Doctoral Dissertations

Purpose: This investigation evaluated the effects of a high-load (50% body weight) eccentric exercise training protocol on reloading myofibrillar damage in soleus (SOL) and extensor digitorum longus (EDL) muscles in rats following 7 days (d) of hindlimb suspension unloading (HSU). Methods: 48 female Sprague-Dawley rats were randomly stratified to four experimental groups; exercise + hindlimb suspension unloading (ExHSU), hindlimb suspension unloading (HSU), exercise (Ex) and control (C). The ExHSU and Ex groups underwent a high-load eccentric exercise protocol for ~2.5 weeks. Following exercise training, the ExHSU and HSU groups underwent 7 d of hindlimb suspension unloading and a subsequent 16-19 …

The Cardiovascular Effects Of Resistance Exercise Training On Orthostatic Intolerance In Elderly Individuals., Lynn P. Rhea

Electronic Theses and Dissertations

One of the age-related changes associated with normal aging is the inability to maintain normal blood pressure homeostasis, a common clinical condition known as orthostatic intolerance. There are little data on the effects of strength training in healthy adults and orthostatic intolerance, and only one study on strength training and elderly adults diagnosed with orthostatic intolerance. Therefore, the purpose of the present study was to evaluate the effects of resistance training on the cardiovascular respones of elderly individuals during an orthostatic challenge.

Thirteen subjects were assigned to either a resistance (RES; n=7; 66±5 yrs.) or a control (CON; n=6; 71±6 …
