Body Mass Bias In A Competition Of Muscle Strength And Aerobic Power, Paul M. Vanderburgh, Lloyd L. Laubach

Health and Sport Science Faculty Publications

Recently, a fitness competition called the Pump and Run (PR) has been popularized. Composed of 2 events, a 5-km road race time (RT) in seconds and a maximal-repetition bench press (BPR) with resistance based on a percentage of body mass (M), the final score (RTadj) equals RT - 30(BPR). From published findings, the authors hypothesized that the PR would impose a bias against heavier competitors. Furthermore, the potential for age bias in this event has not been evaluated. Therefore, the purpose of this study was to investigate M and age bias in the PR for men and women. For 74 …

Effects Of An Angled Starting Block On Sprint Start Kinematics, Nathaniel A. Brown

All-Inclusive List of Electronic Theses and Dissertations

The purpose of the present study was to investigate the effects of an angled proto-type starting block on sprint start kinematics. The angled starting block rotates the foot medially at a 16 degree angle, which emulates the 16 degree angle of the ankle on the medial axis of the foot. This 16 degree should allow for the athlete to apply more force against the block, resulting in a higher velocity at take-off and a faster block clearance time. In the present study, six female collegiate sprinters were filmed and analyzed using the angled starting block and a standard starting block. …

Derivation Of An Age And Weight Handicap For The 5k Run, Paul M. Vanderburgh, Lloyd L. Laubach

Health and Sport Science Faculty Publications

The adverse effect of increasing age and/or body weight on distance run performance has been well documented. Accordingly, nearly all five kilometer (5K) road races employ age categories and, sometimes, a heavier body weight classification. Problems with such conventions include small numbers of runners within older age categories and the advantage given to the lightest runners within each weight category. We developed a 5K Handicap (5KH), a model that calculates an adjusted run time based on the inputs of actual 5K run time, age, and body weight for men and women. This adjusted time, then, can be compared between runners …

Handling Immediate Medical Care At Aquatic Facilities: Do We Need Different Levels Of Lifeguard Certification?, Leland Yarger

International Journal of Aquatic Research and Education

The first-responder and professional-rescuer training materials and training programs consider lifeguards to be first responders in emergencies (Aehlert, 2005; American Red Cross, 2001). This article asks readers to consider whether our agency lifeguard-training programs reflect a philosophy that truly view and prepare lifeguards as first responders. If not, I challenge readers to consider whether we should alter our hiring, staffing, and in-service training procedures at aquatic facilities based on the scope and need for providing adequate emergency care at those facilities.

Correction Factors For Body Mass In Military Physical Fitness Tests, Paul M. Vanderburgh

Health and Sport Science Faculty Publications

Recent research findings combined with the theoretical laws of biological similarity make the compelling case that all physical fitness test items for the Army, Air Force, and Navy impose a 15-20% physiologic bias against heavier, not fatter, men and women. Using the published findings that actual scores of muscle and aerobic endurance scale by body mass raised to the 1/3 power, correction factor tables were developed. This correction factor can be multiplied by one’s actual score (e.g., push-ups, sit-ups, abdominal crunches, or curl-ups repetitions or distance run time) to yield adjusted scores that are free of body mass bias. These …

Validation Of A 5k Age And Weight Run Handicap Model, Paul M. Vanderburgh, Lloyd L. Laubach

Health and Sport Science Faculty Publications

Though increasing age and body weight (BW) have been widely known to be associated with slower distance run times, the common convention in 5K road races is to categorize competitors by age and, sometimes, BW. This has the disadvantage of assigning only small numbers of competitors to age categories and giving advantage to runners close to the minimum age or BW values allowable. Using recent advances in the modeling of distance run performance by BW combined with empirical evidence quantifying the independent effect of age on cardiovascular endurance, we previously published the derivation of the 5K Handicap (5KH), an age …
