Does A Physical Education Bout Alter Percent Body Fat And The Adiposity Health Risk Classification When Using Leg-To-Leg Bioelectrical Impedance Analysis In Girls?, Elise Fitzgerald, Angela Fatool, Curt B. Dixon, Joseph L. Andreacci
International Journal of Exercise Science
Purpose: The purposes of this investigation were to determine: 1) whether a structured in-school physical education exercise bout altered percent body fat (%BF) determined by leg-to-leg bioelectrical impedance analysis (LBIA); and 2) whether the potential exercise-induced %BF magnitude of change altered the health risk classification of the child. Methods: Seventy-six girls (age: 12.2 ± 1.0 yr; height: 153.9 ± 7.5 cm; body mass: 51.9 ± 15.5 kg; BMI: 21.7 ± 5.4 kg/m2) participated in this investigation. LBIA measured %BF values were obtained immediately before and within five minutes after completing a structured, in-school, physical education class. Results: Significant reductions (p < 0.0001) in mean %BF (25.0 ± 10.2 vs. 24.4 ± 10.3 %) were observed for the group following the physical education class. For the majority of the girls (88%), the %BF alteration was less than ± 2.0 %BF. More specifically, the %BF magnitude of change was ± 1.0 %BF in 64.5% of the girls, between 1.1 and 2.0 %BF in 23.7% of the girls, and by more than 2.0 %BF in 11.8% of the girls. Regardless of the %BF magnitude of change, all girls remained in the same adiposity classification category (healthy vs. unhealthy body fat) following exercise. Conclusion: Adhering to the pre-test exercise guideline appears unnecessary when using LBIA to categorize the health risk of an adolescent girl.

Does Standing On A Cycle-Ergometer, Towards The Conclusion Of A Graded Exercise Test, Yield Cardiorespiratory Values Equivalent To Treadmill Testing?, Joshua Mitchell, William B. Kist, Kendall Mears, Jesse Nalls, Kyle Ritter
International Journal of Exercise Science
Graded exercise testing (GXT), per a cycle-ergometer (CE), offers safety and monitoring advantages over treadmill (TM) GXT. Unfortunately, CE-VO2max and some other cardiorespiratory (CR) variables are frequently lower than TM-GXT values. It has been difficult to compare TM and CE-GXT values. However, it was hypothesized that standing towards the conclusion of the CE-GXT (Stand-CE) might increase CE values to those equal to TM-GXT. If Stand-CE and TM-GXT CR values were equal, Stand-CE-GXT could become the method of choice for GXT for the general population. The purpose of this investigation was to investigate the effect of Stand-CE on CR variables. An …

International Journal of Exercise Science
In healthy nonathletic populations, some left ventricle (LV) parameters such as LV mass (LVM) and LV end diastolic dimension (LVEDD) can be predicted by some of body size parameters such as body surface area (BSA), fat-free mass (FFM), and height (H). These body size parameters use to remove covariate influence of body size from cardiac dimension variables and allow comparisons to be made between individuals and groups of different body size. Endurance exercise has been associated with changes in LV size and body composition of athletes. The aim of this study was to evaluate in 30 trained female swimmers (age …

Objective And Subjective Assessments Of ‘Normal’ Walking Pace, In Comparison With That Recommended For Moderate Intensity Physical Activity, Kathryn L. Taylor, Claire Fitzsimons, Nanette Mutrie
International Journal of Exercise Science
Abstract Despite its common application and widely reported health benefits, walking, in relation to pace and intensity, is under-researched. Few studies have addressed whether people normally walk at a pace which meets the public health recommendations for moderate intensity physical activity (1.34-1.79 ms-1) and there is no known research on individuals’ perceptions of factors which influence walking pace. This study aimed to objectively assess if participants were reaching the pace required for moderate intensity physical activity during ‘normal’ walking. This was examined via a Global Positioning System (GPS) over a 1 km outdoor walk and a timed 150 m trial. …

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 …

The Effects Of Indoor Track Curve Radius On Sprint Speed And Ground Reaction Forces, Jesse Tipasa Tukuafu
Theses and Dissertations
Sprinting on a curve is significantly slower than on a straightaway. Although the dimensions vary from track to track, indoor track curves are among the tightest curves that athletes will sprint at maximal speed. Previous studies have provided theories for how speed attenuation occurs when running on a curve. Yet, no previous research has determined how the variability of indoor track curve radii affects trained sprinters at maximal speeds. Purpose: To determine the differences in running speeds, ground time (GT), and medio-lateral (ML) impulse, with different indoor track radii. A secondary purpose was to understand the between-leg differences in GT …

The Effect Of Lateral Spacing On The Spring Start, Kyle Louis Grossarth
Theses and Dissertations
Sprinters are always looking for an improvement in their time, from the gun going off until the finish. An effective start can lead to reaching top velocity sooner and a decreased finish time. New developments in starting blocks, more specifically the width of the starting block pedal, has allowed for variation in foot placement in the blocks. With the ability to change how wide an athlete can place their feet in the blocks, this study looked at trying to find an optimum spacing for college level sprinters. Thirteen Male College Sprinters (mean age = 23.08 years) participated in this study. …

Two important indicators in the gait cycle: arm swing and foot placement, when isolated, provide key information about future behaviors in the gait cycle. Through video captured data, the INSPIRE (Integration of a Sensor Package for Identifying Radical Extremists) project seeks to identify gait characteristics in arm and leg swing movement to recognize threatening individuals. In particular, one approach discussed in this paper uses Groebner Basis Theory to model arm swing movement in the gait cycle. Through inverse kinematics, joint configurations of the shoulder and elbow are found to place the wrist at a specific position and orientation in the …

Insulin-like growth factor (IGF-I) is hypothesized to be a critical upstream regulator of mammalian target of rapamycin (mTOR)-regulated protein synthesis with muscle contraction. We utilized a mouse model that expresses a skeletal muscle specific dominant-negative IGF-I receptor to investigate the role of IGF-I signaling of protein synthesis in response to unilateral lengthening contractions (10 sets, 6 repetitions, 100. Hz) at 0 and 3. h following the stimulus. Our results indicate that one session of high frequency muscle contractions can activate mTOR signaling independent of signaling components directly downstream of the receptor.

While recent studies have suggested that positive developmental outcomes may result from participating in camp experiences, it is unclear what specific aspects of camp (e.g., staff dispositions, counselor teams, non-counselor staff) might influence these camper outcomes. Previous studies have measured the autonomy support of schoolteachers and found that more autonomy-supportive dispositions that, for example, engage autonomy, relatedness, and competence through the use of meaningful choice or rationale have positive effects on student developmental outcomes (e.g., intrinsic motivation, competence, self-esteem). Unlike schools, camps are noncompulsory recreation environments and most are outdoor-based. The existence of differences between the physical, social, and motivational …

Joint Moments And Powers In Healthy Young Adults During Stair Negotiation, Mira M. Momcilovic
Student Work
The primary objective of this study was to determine lower limb joint moments and powers of stair negotiation in healthy young individuals. These results will provide baseline information for future studies with elderly and clinical populations designed to prevent falls that occur during stair negotiation. In previous stair negotiation studies, researchers investigated joint moments and powers initiating stair ascent in front of the stairway. Starting farther away from the stairway allows individuals to stabilize gait velocity and thus, exclude the influence of velocity on joint moments and powers generated during stair ascent. Ten young, healthy individuals underwent gait analysis during …
