Surf Lifeguard Perceptions And Practice Of Cardiopulmonary Resuscitation (Cpr), Kevin Moran, Jonathon Webber
International Journal of Aquatic Research and Education
While the importance of lifeguards in providing immediate and effective basic life support (BLS) in drowning has been well reported, not a lot is known about how lifeguards perceive the relative value of CPR as a lifeguard skill, their training in it, and the likelihood of resuscitation being successful. A self-complete questionnaire was completed by 252 volunteer surf lifeguards at 16 surf beaches in the Greater Auckland,NZ region. Results show that most lifeguards (65%) had received training in the 3 months before the survey, 83% were willing to perform CPR, few (9%) had used CPR in an emergency, and many …

Comparison Of The Ymca Cycle Sub-Maximal Vo2 Max Test To A Treadmill Vo2 Max Test, Jeremy G. Carter, Kelly A. Brooks, Joshua R. Sparks
International Journal of Exercise Science: Conference Proceedings
INTRODUCTION: An individual’s maximum capacity to extract, transport, and utilize oxygen is reflected by their VO2 max (10,22). Numerous physiological factors affect a person’s maximal oxygen consumption. A person’s VO2 max is dependent on their pulmonary, cardiovascular, and muscular systems, which depends on their ventilation-aeration efficiency, central and peripheral blood flow, and metabolism of their active muscles (13,17). The six factors that have the most influence on a person’s maximal aerobic power are heredity, state of training, gender, body size and composition, age, and the mode of the exercise (16). A person’s VO2 max is the gold standard of assessing …

Emg Analysis And Motor Unit Recruitment In The Rectus Femoris Of College Students, Richard G. Crise, Elizabeth L. Franklin, Kelly A. Brooks
International Journal of Exercise Science: Conference Proceedings
The rectus femoris works as part of the quadriceps muscle group to provide the force needed to generate very explosive movements during knee extension. Because many sports require explosive movements from the lower body, many strength coaches implement exercise routines that strengthen the muscles and prevent injuries. In the general population, activities using knee extension are essential in getting the full benefit of a designed exercise program. Muscle fibers provide the contractile force needed to accomplish a movement. Commonly, a deficiency is present in people who tend to favor one leg more than the other during activity. This is due …

Self-Estimation Of Body Fat Is More Accurate In College-Age Males Compared To Females, Halley L. Hancock, Alan P. Jung, John K. Petrella
International Journal of Exercise Science
Objective: To determine the effect of gender on the ability to accurately estimate one’s own body fat percentage. Participants: Fifty-five college-age males and 99 college-age females Methods: Participants estimated their own body fat percent before having their body composition measured using a BOD POD. Participants also completed a modified Social Physique Anxiety Scale (SPAS). Results: Estimated body fat was significantly lower compared to measured body fat percent in females (26.8±5.6% vs. 30.2±7.0%, p<0.001) but not in males (16.8±6.8% vs. 18.1±8.3%, p=0.09). The mean difference between estimated and measured body fat was significantly higher for females compared to males (p<0.001). There was a moderate, significant correlation found between measured body fat percent and SPAS score for males (r=0.331, p=0.014) and females (r=.427, p<0.001). Conclusions: Males estimated their body fat percent more accurately than females. Despite these findings, 62% of males and 76% of females underestimated their body fat.

Body Mass Bias In Exercise Physiology, Paul M. Vanderburgh
Health and Sport Science Faculty Publications
In certain physically demanding occupations, especially the military, body mass bias has substantive implications. Work physiologists have determined that despite body mass bias in the common military physical fitness tests, the larger service members were often better performers of the physically demanding occupational tasks (Bilzon et al., 2002; Lyons et al., 2005; Rayson et al., 2000). That is, they could carry more, more easily evacuate casualties, and better engage in heavy materiel handling. Yet, the smaller personnel were achieving better scores on the physical fitness tests, the results of which have significant promotion and advancement implications (Vanderburgh & Mahar , …
