Effects Of Exercising With A Weighted Vest On The Output Of Lower Limb Joints In Countermovement Jumping, Behdad Tahayori
Effects Of Exercising With A Weighted Vest On The Output Of Lower Limb Joints In Countermovement Jumping, Behdad Tahayori
LSU Master's Theses
The effect of exercising with a weighted vest equal to 15% of body mass on vertical jump height was assessed. It was hypothesized that the defined treatment protocol could enhance jumping performance by increasing hip, knee and ankle joint power. The findings of this study showed that the defined active stretching protocol significantly increases jump height in male participants (0.3364 m compared to0. 3456 m from pre to post exercise respectively) but did not yield a significant increase in females. No significant changes in joint angle, torque, power or velocity were observed between the pre and post exercise jumping. However, …
An Evaluation Of Endurance And Combined Endurance And Resistance Training On Fitness And C-Reactive Protein, Laura A. Daray
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 …
Carotid Intima-Media Thickness And Physical And Cognitive Function In Elderly Men And Women: Role Of Physical Activity, John Brent Jr. Rhodes
Carotid Intima-Media Thickness And Physical And Cognitive Function In Elderly Men And Women: Role Of Physical Activity, John Brent Jr. Rhodes
LSU Master's Theses
The incidence of cognitive impairment in the aging population remains one of the most common morbidities in the elderly, often associated with a decrease in physical function, institutionalization, and death. Several different mechanisms have been proposed, including age-related changes to the vasculature. The purpose of this study was to examine the relationship between physical activity, carotid intima-media thickness and other vascular measures, and measures of cognitive and physical function in older adults. Measures of daily physical activity, vascular structure and function, and cognitive and physical function were examined in 109 participants [age=81±11 yrs]. Daily physical activity was assessed using the …
Comparison Of Brachial Artery Vasoreactivity In Elite Athletes And Age-Matched Controls, Paul Joseph Blalock
Comparison Of Brachial Artery Vasoreactivity In Elite Athletes And Age-Matched Controls, Paul Joseph Blalock
LSU Master's Theses
The ability to distribute blood from areas with low demand to areas with high demand, such as occurs during exercise, is a critical function of the circulatory system. PURPOSE: To compare the resting diameter and vasoreactivity of the brachial artery in elite strength athletes to those of age-matched controls. We hypothesized that the brachial arteries of strength athletes would have larger diameters at rest, and show greater vasoreactivity in response to cuff occlusion and a cold pressor test than in untrained individuals. METHODS: Eight elite strength athletes (age, 23 ± 2 years) and ten age-matched controls (age, 22 ± 1 …
Does Acute Passive Stretching Alter The Optimum Height For Drop Jumping?, Jonathan Samuel Ritchie
Does Acute Passive Stretching Alter The Optimum Height For Drop Jumping?, Jonathan Samuel Ritchie
LSU Master's Theses
The application of static stretching (SS) has previously been shown to limit performance in force production, reaction time, balance and vertical jump height. When looking at the effect of SS on jump performance, researchers have previously used changes in jump height, in squat jumps (SQ), countermovement jumps (CMJ) and drop jumping (DJ) from self selected heights. To date no one has looked at the effect of SS across a range of drop heights. 30 subjects (15 male and 15 female) participated in 1 familiarization trial and four performance trials. All subjects undertook two days of stretching (ST) and two days …
