Effects Of Landing Strategy Intervention On Muscle Activation During Drop Landings, Corrie Bailey
Effects Of Landing Strategy Intervention On Muscle Activation During Drop Landings, Corrie Bailey
Health, Human Performance and Recreation Undergraduate Honors Theses
The purpose of this study was to examine the kinematic, kinetics, and timing of muscle activation of the hamstring and gluteal muscle groups during drop jump landings after five minutes of visual and verbal landing strategy intervention. Thirty-six university students (23.47+/- 2.77 years; 171.99 =?- 8.01 cm; 71.72 =/- 13.56 kg) volunteered to participate. A 5-minute verbal and visual feedback intervention was implemented after participants performed five drop jumps. After the 5-minute intervention, five more drop jumps were performed. The results revealed significant differences in hip and knee flexion, knee valgus, and ground reaction forces pre and post intervention [p<0.05]. In addition, muscle-firing patterns revealed the hamstrings and gluteal muscle groups achieving 20% MVIC prior to the quadriceps muscle group post intervention. The current findings revealed that a 5-minute verbal and visual intervention can elicit greater hip and knee flexion, decrease ground reaction force, and increase the activation of the hamstrings while decreasing the activation of the quadriceps, thereby lessening the likelihood of an ACL injury.
Effects Of Passive Heat Stress On Thermoregulation In Smokers Versus Non-Smokers, Hannah M. Anderson
Effects Of Passive Heat Stress On Thermoregulation In Smokers Versus Non-Smokers, Hannah M. Anderson
Health, Human Performance and Recreation Undergraduate Honors Theses
Context: Maintaining thermal balance under heat-stress depends on appropriate increases in sweating and skin blood flow (cutaneous vasodilation). Given the multiple effects on nicotine on the body, it is unknown if sweating and cutaneous vasodilation are impaired, or possibly enhanced in smokers during heat stress. Objective: To examine the effects of passive heating on thermoregulatory responses (i.e., sweating and cutaneous vasodilation) in smokers versus non-smokers. Design: 1 passive heat trial per subject. Patients or Other Participants: 14 male smokers (26 ± 7 y; 180.0 ± 5.5 cm; 81.2 ± 20.7 kg; 3.2 ± 1.9 packs/week) and 12 male non-smokers (26 …
Entering Collegiate Women's Decision To Discontinue Particpation In Sports: A Qualitative Study, Emily Gilliam
Entering Collegiate Women's Decision To Discontinue Particpation In Sports: A Qualitative Study, Emily Gilliam
Health, Human Performance and Recreation Undergraduate Honors Theses
This study was conducted to gather information about why collegiate women discontinue participation in sports. Women at a Midwestern Division III institution participated in this study. Three groups of women were interviewed through focus groups: women no longer playing a sport, women currently playing collegiate athletics, and a mix of women currently playing a college sport and women no longer involved. The women were asked questions about sport involvement and answered collectively. Women provided responses that fell into 5 main categories: psychological, physical, educational, social, and attachment. Physical responses were those that dealt with health issues; some felt that the …
The Effects Of Physical Activity Education On Exercise Self-Efficacy And Physical Activity: A Comparison Study Between Exercise Science And Physical Education Teacher Education, Megan Wojcicki
Health, Human Performance and Recreation Undergraduate Honors Theses
The purpose of this study was to understand the adjustment families undergo when a child is diagnosed with deafness as well as their adjustment to the child hearing after a cochlear implant is in place. The participants of the study were four hearing adults between the ages of 18-28 who have a younger sibling with a cochlear implant. The qualitative study used reports from four participants to reflect on how hearing loss and subsequent cochlear implantation impacted the family’s lives. Contrary to expecting findings, the themes did not change and all four reported nurturing and personal growth as key themes.
Landing Mechanics Of Military Personnel And Effects Of A Lumbopelvic Hip Complex 6 Week Intervention Program, Derek Wahl
Landing Mechanics Of Military Personnel And Effects Of A Lumbopelvic Hip Complex 6 Week Intervention Program, Derek Wahl
Health, Human Performance and Recreation Undergraduate Honors Theses
The purpose of this study was to determine if a six-week lumbopelvic-hip complex [LPHC] intervention program would affect the landing mechanics of active ARMY ROTC cadets. Ten male Army ROTC cadets [182.3 + 4.5 cm; 86.7 + 9.2 kg; 19.5 + 0.8 yrs] were recruited for this study. Participants performed a drop landing protocol pre and post LPHC intervention program. The LPHC intervention program consisted of six minutes of five body weight exercises prior to every organized ROTC conditioning that occurred three days a week for six weeks; consisting of 10 total exercises that were randomly alternated throughout the treatment …
Hip Abduction Strength And Its Relationship With Sequential Movement And Ball Velocity In Softball Players, Sarah Kaminski
Hip Abduction Strength And Its Relationship With Sequential Movement And Ball Velocity In Softball Players, Sarah Kaminski
Health, Human Performance and Recreation Undergraduate Honors Theses
This study examined the relationship between hip abduction strength, segmental sequentiality of the upper extremity and ball velocity of throwing in softball positional players. Hip abduction strength, ball velocity, and related kinematics were collected on sixteen (167.7 + 6.7 cm; 68.9 + 10.4 kg; 19.2 + 1.1 yrs) National Collegiate Athletic Association Division I softball players. The participant had to catch a simulated hit ball and perform her positional throw. A position player was on second base and only those throws that she was able to catch without stepping off the base were recorded. There was no significance in the …
