Loading Rate In Self-Initiated Vertical Jump Landings: Developmental And Gender Comparisons, Pamela Russell, Erik Swartz, Ron Croce, Laura Decoster
Loading Rate In Self-Initiated Vertical Jump Landings: Developmental And Gender Comparisons, Pamela Russell, Erik Swartz, Ron Croce, Laura Decoster
Pamela J. Russell
The study compared gender and developmental differences in vertical loading rate upon a two-footed landing from a self-initiated VJ. Fifty-seven subjects grouped by age (pre-pubescent (8-11 yrs); post-pubescent (19-29 yrs)) and gender consented to participate. Subjects jumped for a ball set at 50% of their maximum VJ height, and landed on two feet, facing forward, with only their dominant foot on the force plate. Motion analysis (3-D) and ground reaction force (GRF) data were collected. Statistical analyses indicated significant developmental differences in vertical loading rate normalized to kinetic energy, but no gender differences. Children may have higher loading rates because …
Predictors Of Adolescent Male Body Image Dissatisfaction: Implications For Negative Health Practices And Consequences For School Health From A Regionally Representative Sample, James Leone, Joyce Fetro, Mark Kittleson, Kathleen Welshimer, Julie Partridge, Stacia Robertson
Predictors Of Adolescent Male Body Image Dissatisfaction: Implications For Negative Health Practices And Consequences For School Health From A Regionally Representative Sample, James Leone, Joyce Fetro, Mark Kittleson, Kathleen Welshimer, Julie Partridge, Stacia Robertson

BACKGROUND: Adolescent males are more likely to sustain intentional and unintentional injuries, be involved in a physical confrontation, and be successful in suicide attempts. Body image dissatisfaction (BID) has been linked as a possible contributing factor to these negative health behaviors and risks; however, research is limited with males. The interaction of intrapersonal, interpersonal, and social variables in a holistic model has yet to be explored for males. Variables precipitating adolescent males to develop an unhealthy body image and act on negative health behaviors, such as body image drug use, were the impetus for this study. METHODS: A randomized cross-sectional …
Individual, Occupational And Biomechanical Factors That Affect Slip And Fall Risk From Fixed Ladders, Erika Mae Pliner
Individual, Occupational And Biomechanical Factors That Affect Slip And Fall Risk From Fixed Ladders, Erika Mae Pliner
Theses and Dissertations
Injuries from ladder falls are prevalent and severe. Previous research has examined certain elements of ladder falls such as the ladder base slipping, but few studies have examined the factors that contribute to climbers falling from the ladder, particularly for permanent/fixed ladders. In addition, the biomechanical response to a ladder slip/misstep during ladder climbing and the factors that affect a fall from a ladder are not well understood. This thesis is a two part study that simulated ladder slips and missteps in order to find factors 1) associated with ladder slip risk and 2) that decrease fall severity from a …
Sex Differences In Change In Skin Temperature When Exercising In A Hot, Humid Environment, Adam S. Venable, Eric A. Prado, Andrea L. Henning, David W. Hill, Jakob L. Vingren, Brian K. Mcfarlin
Sex Differences In Change In Skin Temperature When Exercising In A Hot, Humid Environment, Adam S. Venable, Eric A. Prado, Andrea L. Henning, David W. Hill, Jakob L. Vingren, Brian K. Mcfarlin
International Journal of Exercise Science: Conference Proceedings
The risk for heat-related illness is increased when exercising in a hot, humid environment. In an effort to protect the athlete, body temperature is measured continuously while exercising in extreme environments. Currently, researchers and laboratory personnel employ the use of mean skin temperature to monitor athlete safety; however, this measurement fails to consider localized changes in temperature that may arise as a function of sex and exercise time. Therefore, the purpose of this study was to examine potential sex differences in the change in skin temperature at 17 different upper body locations while exercising in a hot, humid environment. Young …
Visceral Fat Prediction Models According To Age And Gender, Serena Chang
Visceral Fat Prediction Models According To Age And Gender, Serena Chang
International Journal of Exercise Science: Conference Proceedings
Obesity is the leading risk factor for metabolic syndrome and puts individuals at an increased risk for cardiovascular disease and diabetes.Past studies have shown that visceral adipose tissue (VAT), rather than subcutaneous fat (SF), is a major predictor of these disorders.VAT is the fatty tissue surrounding the vital organs, while SF is the fat found directly beneath the skin. SF’s primary function is to provide energy storage while VAT cells are metabolically active and have been linked to increased insulin resistance, production of triglycerides and low density lipolipids, which contribute to a higher risk of health diseases.Due to lack of …

This article examined a typology of female hunters, factors constraining participation, and negotiation strategies females used to overcome constraints. A survey of Oregon hunters was conducted in the summer of 2010 to understand hunting characteristics using the 2008 big game license database (n = 392). We created a typology of female hunters using a cluster analysis of Recreation Experience Preference items. Four clusters were identified: less-engaged, family oriented, nature-sport, and all around enthusiast. Analysis of variance revealed differences among female hunter segments. Differences existed among the four groups on both constraints and negotiation strategies. One of the notable groups was …
The Association Of Gender And Socioeconomic Position With Cardiorespiratory Fitness In Adolescents, Quentin Oliphant
The Association Of Gender And Socioeconomic Position With Cardiorespiratory Fitness In Adolescents, Quentin Oliphant
Walden Dissertations and Doctoral Studies
This meta-analysis investigated the association of gender and socioeconomic position with cardiorespiratory fitness in adolescents. Public health professionals know the importance of physical activity level as a modifiable behavior; however, the literature has revealed that more research is needed on the association of sociodemographic variables like gender and socioeconomic position with cardiorespiratory fitness in adolescents. Using the physical fitness and health outcomes conceptual model as a guide, the overall effect sizes across studies were assessed as well as the moderators of study design, sample size, age, and country. A systematic review of literature identified a total of 18 peer-reviewed studies …
