Recreational Cyclists: The Relationship Between Low Back Pain And Training Characteristics, Samantha J. Schulz, Susan J. Gordon

International Journal of Exercise Science

This study investigated the relationship between low back pain (LBP) and training characteristics in recreational cyclists. Purposive sampling was used to recruit sixty-six recreational cyclists from nine cycling clubs. Participants completed a survey reporting training characteristics and LBP behaviour during a usual week of cycling. This included percent of time spent cycling in three common riding positions, cycling terrain, average cycling pace, number of gears, days per week cycled and number of cycling events per year. Fifty percent reported LBP during or after cycling or smoking and LBP. Cyclists who reported LBP cycled significantly further in a usual week of …


Delayed Wound Healing: Can Exercise Accelerate It?, K Todd Keylock, Hilary Young 2010 Bowling Green State University

Delayed Wound Healing: Can Exercise Accelerate It?, K Todd Keylock, Hilary Young

International Journal of Exercise Science

Poorly healing wounds affect millions around the world, yet preventive methods and low-cost, effective treatments are few. Wounds heal quickly through well-coordinated phases in those who are healthy and active but can become chronically nonhealing as a result of disease and inactivity. Recently it has been reported that moderate aerobic exercise accelerated healing rates in the aged. High levels of inflammation are known to delay wound healing, and aging and disease are associated with chronically increased inflammation. Therefore, exercise may help speed healing by reducing inflammation to healthier levels not only in the aged, but also in other populations with …


Concurrent Visual Feedback, Practice Organization, And Spatial Aiming Accuracy In Rapid Movement Sequences, David E. Sherwood‡, Brian Duffell* 2010 University of Colorado at Boulder

Concurrent Visual Feedback, Practice Organization, And Spatial Aiming Accuracy In Rapid Movement Sequences, David E. Sherwood‡, Brian Duffell*

International Journal of Exercise Science

Int J Exerc Sci 3(2) : 78-91, 2010. While the availability of visual feedback is a well-known factor influencing the accuracy of rapid aiming movements, little is known about how vision might interact with a contextual variable like practice organization. In the current study, the interaction of concurrent visual feedback (CVF) and practice organization on aiming movement accuracy was investigated in the dominant limb of 40 college-aged participants. Participants performed “triplets” of rapid aiming movements with a lightweight lever in the sagittal plane involving short (20°), medium (40°), long (60°) distances and were randomly assigned to one of four groups …

Myogenin Modulates Exercise Endurance By Altering Skeletal Muscle Metabolism, james eric meadows 2010 University of Texas Graduate School of Biomedical Sciences at Houston

Myogenin Modulates Exercise Endurance By Altering Skeletal Muscle Metabolism, James Eric Meadows

Dissertations and Theses (Open Access)

The function of myogenic regulatory factors (MRFs) during adult life is not well understood. The requirement of one of these MRFs, myogenin (Myog), during embryonic muscle development suggests an equally important role in adult muscle. In this study, we have determined the function of myogenin during adult life using a conditional allele of Myog. In contrast to embryonic development, myogenin is not required for adult viability, and Myog-deleted mice exhibited no remarkable phenotypic changes during sedentary life. Remarkably, sedentary Myog-deleted mice demonstrated enhanced exercise endurance during involuntary treadmill running. Altered blood glucose and lactate levels in sedentary Myog-deleted mice after …

International Journal of Exercise Science

Int J Exerc Sci 3(2) : 64-67, 2010. The purpose of this study was to evaluate the effect of the E3 Fitness Grips (BioGrip, Inc., Rancho Cordova, CA) on running economy, as measured by oxygen uptake (VO2), and heart rate (HR) during submaximal treadmill running. Eleven subjects, seven female and four male, completed a submaximal running test on a treadmill while VO2 and HR were measured continuously. After achieving steady-state at a speed and grade that elicited a VO2 equivalent to 70% VO2max, the subjects ran for five minutes holding the E3 Fitness Grips (G) and five minutes without the …

The Correlation Between Visual Observations And Inclinometric Measurements For Special Tests Related To Patellofemoral Pain Syndrome, Erin Quada 2010 Old Dominion University

The Correlation Between Visual Observations And Inclinometric Measurements For Special Tests Related To Patellofemoral Pain Syndrome, Erin Quada

Human Movement Studies & Special Education Theses & Dissertations

Patellofemoral pain syndrome (PFPS) is generally described as an insidious onset with pain increasing during running, jumping, ascending and descending stairs as well as sitting with the knees flexed for an extended period of time. Clinicians often use special tests in injury evaluations and range of motion assessments, usually making a visual observation of that status of the patient. The purpose of this study was to examine how interval measurements utilized in flexibility and range of motion assessments correlate with visual observations of special tests (active knee extension test, Thomas test, Ober's test, rectus femoris flexibility, and Craig's test). The …


The Effects Of Two Different Fatigue Protocols On Lower Extremity Kinematics And Kinetics During An Unanticipated Running Stop-Jump, David L. Quammen 2010 Old Dominion University

The Effects Of Two Different Fatigue Protocols On Lower Extremity Kinematics And Kinetics During An Unanticipated Running Stop-Jump, David L. Quammen

Human Movement Studies & Special Education Theses & Dissertations

Altered neuromuscular control strategies and biomechanical movement risk factors are most likely to contribute to the increased incidence of non-contact ACL injury for female athletes. Neuromuscular control strategies and movement patterns are further altered when the effects of fatigue are present. The purpose of this study was to determine neuromechanical differences between two fatigue protocols [Slow Linear Oxidative Fatigue Protocol (SLO-FP) and Functional Agility Short-Term Fatigue Protocol (FASTFP)] when performing a running stop-jump task (RS). A sample of convenience of fifteen Division I female soccer players (age= 19.2 ± 0.8 years; height= 1.67 ± 0.05 m; mass= 61.7 ± 8.1 …
