Contributions Of Body Fat And Effort In The 5k Run: Age And Body Weight Handicap, Anne R. Crecelius, Paul M. Vanderburgh, Lloyd L. Laubach

Health and Sport Science Faculty Publications

The 5K handicap (5KH), designed to eliminate the body weight (BW) and age biases inherent in the 5K run time (RT), yields an adjusted RT (RTadj) that can be compared between runners of different BW and age. As hypothesized in a validation study, however, not all BW bias may be removed, because of the influences of body fatness (BF) and effort (run speed; essentially the inverse as measured by rating of perceived exertion (RPE)). This study's purpose was to determine the effects of BF and RPE on BW bias in the 5KH. For 99 male runners in a regional 5K …

Aging And Partial Body Weight Support Affects Gait Variability, Anastasia Kyvelidou, Max J. Kurz, Julie L. Ehlers, Nikolaos Stergiou

Journal Articles

Background: Aging leads to increases in gait variability which may explain the large incidence of falls in the elderly. Body weight support training may be utilized to improve gait in the elderly and minimize falls. However, before initiating rehabilitation protocols, baseline studies are needed to identify the effect of body weight support on elderly gait variability. Our purpose was to determine the kinematic variability of the lower extremities in young and elderly healthy females at changing levels of body weight support during walking.

Methods: Ten young and ten elderly females walked on a treadmill for two minutes with a body …

Occupational Relevance And Body Mass Bias In Military Physical Fitness Tests, Paul M. Vanderburgh

Health and Sport Science Faculty Publications

Recent evidence makes a compelling case that U.S. Army, Navy, and Air Force health-related physical fitness tests penalize larger, not just fatter, service members. As a result, they tend to receive lower scores than their lighter counterparts, the magnitude of which can be explained by biological scaling laws. Larger personnel, on the other hand, tend to be better performers of work-related fitness tasks such as load carriage, heavy lifting and materiel handling. This has been explained by empirical evidence that lean body mass and lean body mass to dead mass ratio (dead mass = fat mass and external load to …

Physical Education Content Knowledge And Physical Activity Behaviors Of Mississippi High School Students, Christina Leigh Lumpkin Martin

Dissertations

The present study investigated physical education content knowledge, physical activity behaviors, and body mass indexes of 386 Mississippi ninth (n=236 ) and twelfth (n=150) grade students with a goal of establishing evidence-based needs to modify physical education curricula. Results of this study suggested that a significant, direct relationship did exist in the Assessment of Sub-disciplinary Knowledge in Physical Education: Exercise Physiology (ASK PE: EXP);(Ayers, 2004) scores and scores from the Modifiable Activity Questionnaire for Adolescents (M4<2^4);(Aaron & Kriska, 1997) for both ninth and twelfth grade students. Findings also suggested that physical education content knowledge (exercise physiology) is more likely to contribute to twelfth grade reported physical activity scores than ninth grade reported physical activity scores. However, ninth graders were more active than twelfth graders. This is possibly explained by the small difference (5%) in ASK PE: EXP scores between ninth (M ASK PE: EXP score = 52%, SD=.22) and twelfth graders (M ASKPE: EXP score = 57%, SD = .21). As a whole, results indicated that Mississippi ninth and twelfth grade students' average ASKPE: EXP score was lower (M = 53%, SD = .22) than students in 16 other states (M = 62%, SD = 7.65). Further, majority of Mississippi high school students are performing significantly below the established, research-based cutoff score of 62% (observed N below 62% = 236 and observed N above 62% = 150). This is notable, because findings also suggested that students who scored higher (M knowledge = 76%, SD = .08);(M activity = 8.6 hours/week, SD = 9.7) or above 62% on the ASK PE: EXP were more likely to be active during a weekly basis compared to those who scored lower (M knowledge = 39%, SD = .14);(M activity = 5.8 hours/week, SD = 9.8) or below a 62% on the ASK PE: EXP. With this noted, it was recommended that Mississippi high schools evaluate the current physical education programs, and strive to implement curricula that can provide students with the necessary knowledge and skills to make lifelong healthy decisions.

The purpose of this investigation was to determine the stability reliability of the Digijump device for the commonly used laboratory measures of oxygen uptake (VO2), heart rate (HR), and rate of perceived exertion (RPE). College-aged individuals (N = 17) completed two 3-min repetitive jumping bouts on the Digijump machine (120 jumps per minute, jump height = 1.27 cm) at …

Swim Positioning And Its Influence On Triathlon Outcome, Grant J. Landers†, Brian A. Blanksby‡, Timothy R. Ackland‡, Ronald Monson†

International Journal of Exercise Science

Questions have been raised regarding which of the three legs of a triathlon influences the final finishing position. Some coaches subjectively believe that the swim and run are more important than the cycle, especially since the introduction of drafting during the cycle. This study analysed race position shifts between each of the three disciplines to assess the importance of the swim finish position and final finish position during draft legal Olympic distance triathlon events. Ten male and 10 female triathlon world cup events during one season were analysed. The results suggested that the triathlon swim leg is important because the …

Development Of A Technique To Diagnose Subtalar Joint Instability, Ajaya Dhakal

Mechanical & Aerospace Engineering Theses & Dissertations

Most patients escape diagnosis of subtalar joint instability for years before treatment. Therefore, a clinically relevant technique to diagnose subtalar joint instability will improve its management. Towards this goal, a six degree of freedom positioning and loading device was developed to apply physiologic loads to the hindfoot. Because the ideal loading configuration to detect subtalar joint instability is unknown, the device was designed to apply rotational and translational forces simultaneously. Specifically, plantarflexion/dorsiflexion, inversion/eversion, and internal/external rotation can be applied individually or as coupled motions along with an anterior/posterior drawer. Kinematic data were collected from calcaneus, talus and tibia using a …

Relationship Of Vo2 Peak, Body Fat Percentage, And Power Output Measured During Repeated Bouts Of A Wingate Protocol, John R. Mclester‡, J. Matthew Green‡, P. Jason Wickwire†, Thaddeus R. Crews‡

International Journal of Exercise Science

The principle of specificity would indicate that being aerobically trained would not necessarily enhance performance in events relying principally on oxygen-independent metabolic pathways (i.e. “anaerobic” exercise). Body fatness may be associated with aerobic and anaerobic performance. VO2 Peak was determined with a graded cycle ergometry and, in a separate session 4 consecutive Wingate power tests (3 min recovery) in 31 males. Pearson correlations were calculated for VO2 Peak and Body Fat Percentage with Peak Power, Mean Power, Minimum Power, Fatigue Index, Peak Heart Rate, and Recovery Heart Rate. No significant correlations were found for VO2 Peak or Body Fat Percentage …
