Biomechanical Analysis Of Race Walking Compared To Normal Walking And Running Gait, Jaclyn D. Norberg 2015 University of Kentucky

Biomechanical Analysis Of Race Walking Compared To Normal Walking And Running Gait, Jaclyn D. Norberg

Theses and Dissertations--Kinesiology and Health Promotion

Human locomotion is phenomenon that is extraordinarily complex. It is evident that a complete description of locomotion involves consideration of kinematics, kinetics, and muscle activity of the extremities in all of their various movements. Race walking (RW) is a form of upright locomotion that differs from normal walking and running by its form dictated by the International Amateur Athletics Federation (IAAF). Despite the similarities to both normal walking (NW) and running (RU), RW has not been the subject of equally intensive investigations.

This study explores the comprehensive biomechanics of race walking and how it compares to NW and RU. A ...


Analysis Of Road Sprint Cycling Performance, Paolo Menaspa 2015 Edith Cowan University

Analysis Of Road Sprint Cycling Performance, Paolo Menaspa

Theses: Doctorates and Masters

Sprint cycling ability is a key determinant of road cycling performance, with many races designed specifically for sprinters. The ability to excel in the final sprint is relevant for both individual riders and teams. Despite the importance of sprints within professional road cycling, the characteristics of professional road sprints and sprinters have yet to be extensively described. Thus, the overall objective of the five research studies contained within this doctoral thesis was to describe road cycling sprint performance and improve the general understanding of the physical, technical and tactical factors associated with such performances.

The first two descriptive field studies ...


Muscular And Neural Contributions To Postactivation Potentiation, Brian Joseph Wallace 2015 University of Kentucky

Muscular And Neural Contributions To Postactivation Potentiation, Brian Joseph Wallace

Theses and Dissertations--Kinesiology and Health Promotion

Muscle performance is partially a consequence of its recent contractile history. Postactivation potentiation (PAP) can occur after muscle contractions and leads to enhanced neuromuscular performance. The purpose of this dissertation was to explain the relationship between muscle factors (twitch potentiation, TP) and neural factors (reflex potentiation, RP) contributing to overall PAP following a non-fatiguing volitional muscle contraction. The tibial nerves of fifteen resistance trained volunteers (eleven men, four women) were stimulated intermittently at supramaximal (Mmax) and submaximal (Hmax) intensities for 20 minutes on separate days under three conditions: rest (Control); after a after a 10 second maximum voluntary isometric contraction ...

Upper Limb Ambidexterity In The Wrestling Snap Down Technique, Nicholas A. DeCastro 2015 Bridgewater State University

Upper Limb Ambidexterity In The Wrestling Snap Down Technique, Nicholas A. Decastro

Undergraduate Review

The sport of wrestling dates back as far as recorded history. Folk style is a subdivision of that ancient sport, considered the most popular form of wrestling in U.S high schools and universities. An important skill used by Folk style wrestlers is the snap down technique. However, there is a lack of scientific literature that examines the kinematic motions of the snap down technique bilaterally. Understanding athletic ambidexterity is an important factor in athletic performance and injury prevention, particularly in wrestling. Therefore, the purpose of the research study was to bilaterally examine the kinematic motions of the upper extremity ...


Influence Of Traditional And Nontraditional Entries On Figure Skating Jumps, Bryanna L. Nevius 2015 Bridgewater State University

Influence Of Traditional And Nontraditional Entries On Figure Skating Jumps, Bryanna L. Nevius

Undergraduate Review

The purpose of this study was to determine whether or not adding a non-traditional jump entry into a routine is more beneficial to the skater or if there is more value in performing the same jump with a traditional entry. Specifically, the study examined the kinematics of a non-traditional verses a traditional jump entry by looking at the angles of the hip, knee, and ankle joints at take-off and landing. Maximum jump height, airtime, and horizontal displacement were also examined. It was hypothesized that non-traditional entries would change jump kinematics when compared to the same jumps performed from traditional entries ...

Acl Injuries In Female Athletes: Are Prevention Programs The Answer?, Brooke Chandor 2015 Colby College

Acl Injuries In Female Athletes: Are Prevention Programs The Answer?, Brooke Chandor

Honors Theses

Around 400,000 people tear their anterior cruciate ligaments (ACLs) every year in the United States. The majority of these injuries occur during athletics, and most commonly to females. Their neuromuscular abilities, anatomies, and hormones put female athletes at a much higher risk of ACL injury than male athletes. The current gold standard of treatment, ACL reconstruction, is an imperfect technique at best. It leaves patients with much higher risk of both ACL reinjury and early onset of osteoarthritis. Prevention programs, aimed at reducing the neuromuscular risk factors in female athletes, have proved to effectively reduce the number of noncontact ...

Should Educators Be ‘Wrapping School Playgrounds In Cotton Wool’ To Encourage Physical Activity? Exploring Primary And Secondary Students’ Voices From The School Playground, Brendon P. Hyndman, Amanda Telford

Australian Journal of Teacher Education

Physical activity in school playgrounds has changed considerably over recent decades to reflect a climate of ‘surplus safety’. A growing culture of surplus safety can be attributed to a desire of parents and teachers responsible for children to protect school students from danger. The aim of this research was to examine students’ perceptions of playground safety influences on physical activity during school breaks from the perspectives of the ‘users’ of school playgrounds. Data collection consisted of seven focus groups (4 primary school & 3 secondary school) conducted across four schools (2 primary & 2 secondary). During this study, the focus group discussions consisted of 54 children (32 primary & 22 secondary; 50% females; 50% males). Social-Ecological Model levels of school playground safety influence identified by both primary and secondary ...

Male (n = 19) and female (n = 20) recreational athletes were recruited and stratified according to 40 m sprinting ability, then randomly allocated to one of two groups: horizontally-directed plyometric training (HT) and vertically-directed plyometric training (VT).

The groups performed the experimental procedures twice each week with the same number of total ground contacts, while maintaining their ...


The Effect Of Β-Hydroxy-Β-Methylbutyrate (Hmb) Supplementation On Neuromuscular Performance Following Fatiguing Exercise In Healthy Subjects, Jordon W. Macht 2015 University of Kentucky

The Effect Of Β-Hydroxy-Β-Methylbutyrate (Hmb) Supplementation On Neuromuscular Performance Following Fatiguing Exercise In Healthy Subjects, Jordon W. Macht

Theses and Dissertations--Kinesiology and Health Promotion

Supporters of a nutritional supplement, β-Hydroxy-β-Methylbutyrate (HMB) supplementation, claim that it will increase the muscular strength gains and lean muscle mass gains seen during a resistance training program. It has been suggested that HMB supplementation does this by preventing muscle damage or by regenerating damaged muscle cell membranes. However, no research has evaluated the effect of HMB supplementation on low frequency fatigue. Therefore, the purpose of this study was to determine if three weeks of HMB supplementation could attenuate the effects of low frequency fatigue caused by eccentric muscle contractions of the tibialis anterior muscle. A total of 33 healthy ...


The Effect Of Fluid Periodization On Athletic Performance Outcomes In American Football Players, Christopher W. Morris 2015 University of Kentucky

The Effect Of Fluid Periodization On Athletic Performance Outcomes In American Football Players, Christopher W. Morris

Theses and Dissertations--Kinesiology and Health Promotion

For decades strength and conditioning professionals have been seeking optimal training volumes and intensities to yield maximum performance outcomes without the onset of injury. Unfortunately, current studies apply experimental training techniques without considering the individuals’ response to the imposed training load. Due to the vast genetic variability and extraneous environmental factors that affect one’s ability to recover, results from such studies are controversial and inconclusive. Athlete monitoring systems offer an objective assessment that is purported to evaluate an individual’s physiological readiness to adapt to an overload stimulus and thus allow for daily manipulations in training loads (i.e ...
