International Journal of Aviation, Aeronautics, and Aerospace

Introduction: Neck pain (NP) and low back pain (LBP) are prevalent among military helicopter pilots. Although there have been few studies on sex differences in the NP/LBP prevalence in this population, females are shown to be at a greater risk of NP/LBP in civilian studies. This disparity may be due to musculoskeletal characteristics differences that predispose females for NP/LBP. The purpose of this study was to compare cervical and trunk musculoskeletal characteristics between male and female pilots. Methods: A total of 8 female pilots (Age: 27.6 ± 4.2yrs, HT: 166.1 ± 7.7cm, WT: 67.9 ...

Effects Of Static Stretching On Squat Performance In Division I Female Athletes, Clare F. Heisey, J. Derek Kingsley

International Journal of Exercise Science

International Journal of Exercise Science 9(3): 359-367, 2016. Static stretching was once recognized as a method of preparation for physical activity that would inhibit performance and increase risk of injury. However, a growing body of research suggests that static stretching may not have an inhibitory effect. Regardless, the data have not examined gender differences or the fatigue index (FI) and flexibility effects of static stretching on the back squat over multiple sets. Therefore, the purpose of this study was to examine the relationship between a static-stretch condition (SC) and control condition (CC) on flexibility and the FI of Division ...

Individual Differences In The Programming Of Rapid Bimanual Movements: Are Two Modes Better Than One?, Ashley N. Vander Does, David E. Sherwood

International Journal of Exercise Science

International Journal of Exercise Science 9(3): 347-358, 2016. One of the challenges in performing simultaneous bimanual movements is to prevent interference from one limb to the other, thereby maintaining spatial accuracy in both limbs. Prior research has shown that when a longer distance movement is performed with a shorter movement, the shorter movement overshoots its target and the longer movement undershoots its target relative to control conditions where two shorter or two longer movements are made. The current experiment investigated the motor control strategies used by participants when performing simultaneous aiming movements combining both different and same distances. Participants ...

Older Women’S Muscle And Gait Response To A Bout Of Exercise Differs By Physical Activity Level, Jocelyn F. Hafer, Katherine A. Boyer

UMass Center for Clinical and Translational Science Research Retreat

Changes in gait are a consequence of aging and likely contribute to knee osteoarthritis (OA) incidence. Decrements in muscle function with age, including muscle power and fatigue resistance, may contribute to changes in gait and, subsequently, knee OA. Examining the impact of habitual physical activity (PA) on gait mechanics and muscle function may provide insight for interventions to modify knee OA risk. As knee OA affects women at greater rates than men, the current study focused on older women. The aim of this study was to determine if older women with different levels of habitual PA experienced the same effect ...
