Nirsa Members' Perceptions Of Organizational Effectiveness, Corinne M. Daprano, Donna Pastore, Carla Costa

Health and Sport Science Faculty Publications

This study assessed National Intramural-Recreational Sports Association (NIRSA) members’ perceptions of effectiveness in a sport association. Specifically, this study investigated the extent to which professional members of NIRSA perceive it to be effective in achieving its stated and operative goals. A stratified systematic sample of professional NIRSA members (N = 600) was selected to complete the survey.

Evaluation Of A Simple Intervention To Increase Self- Efficacy For Independent Exercise In Cardiac Rehabilitation Participants, Sherry A. Barkley

Electronic Theses and Dissertations

Purpose: While benefits of exercise after a cardiac event are well documented, participation in and adherence to cardiac rehabilitation (CR) programs is often low. The purpose of this study was to test the effectiveness of a self- efficacy coaching intervention (SCI): a simple theory-based behavioral intervention to increase self-efficacy for independent exercise as well as independent exercise behavior in CR patients. It was hypothesized that persons receiving the SCI treatment (T) would have higher levels of self-efficacy for exercise and greater participation in independent exercise than participants in an attention control (C) group.
Methods: People referred to a hospitalbased CR …

International Perspective Of Aquatic Instructors’ Attitudes Toward Teaching Swimming To Children With Disabilities, Phillip Conatser

International Journal of Aquatic Research and Education

The purpose of this study was to examine attitudes of aquatic instructors (N = 23) toward teaching swimming to children with mild and severe disabilities in an inclusive setting. Aquatic instructors from 23 cities in 7 countries participated in the study. Data were collected by mail survey using the Aquatic Instructors Attitudes Toward Teaching Swimming to Individuals With Disabilities questionnaire (Conatser, Block, & Lapore, 2000). A correlated t test showed that aquatic instructors were significantly more favorable toward teaching aquatics to children with mild disabilities than children with severe disabilities. Instructors agreed they should include children with mild disabilities and …

Effect Of Carbohydrate-Protein Supplement Timing On Acute Exercise-Induced Muscle Damage, James P. White, Jacob M. Wilson, Krista G. Austin, Beau K. Greer, Noah St. John, Lynn B. Panton

All PTHMS Faculty Publications

Purpose:

To determine if timing of a supplement would have an effect on muscle damage, function and soreness.

Methods:

Twenty-seven untrained men (21 ± 3 yrs) were given a supplement before or after exercise. Subjects were randomly assigned to a pre exercise (n = 9), received carbohydrate/protein drink before exercise and placebo after, a post exercise (n = 9), received placebo before exercise and carbohydrate/protein drink after, or a control group (n = 9), received placebo before and after exercise. Subjects performed 50 eccentric quadriceps contractions on an isokinetic dynamometer. Tests for creatine kinase (CK), maximal voluntary contraction (MVC) and …

The Need For Advanced Cardiac Life Support Certification For Open-Water Lifeguards At Huntington Beach, Ca, Daniel Jerome, Peter R. Chambers, Steve Reuter, John Porcari

International Journal of Aquatic Research and Education

The number of people visiting U.S. beaches increased in 2007 to more than 240 million people. This increase in activities does not come without danger. Lifeguards maintain beach safety, but little research is available to assist us in determining appropriate certification levels for lifeguards. The authors analyzed various injuries that occurred in the open-water environment of Huntington Beach, CA. Based on the nature of the injuries, they attempted to determine the level of training lifeguards needed. The vast majority of injuries (99%) were soft-tissue injuries, musculoskeletal injuries, or environmental injuries. It was felt that lifeguards with first-aid and basic-life-support (BLS) …

Motivations And Reasons For Exercising In Water: Gender And Age Differences In A Sample Of Spanish Exercisers, Juan Antonio Moreno Murcia, Celestina Martínez Galindo, Pablo Marcos Pardo

International Journal of Aquatic Research and Education

The purposes of this study were, on the one hand, to relate the reasons for exercising with self-determination and, on the other, to check gender and age differences with a sample of 311 exercisers in water. The data were collected using the Behavioral Regulation in Exercise Questionnaire–2 and Motives for Physical Activities Measure–Revised. A positive and significant correlation was seen between self-determination and the reasons for exercise, with self-determination predicting 22% by enjoyment and 8% by fitness/health reasons. Similarly, the multivariate analysis showed that the women had more self-determination than the men and that they also rated fitness/health, social, enjoyment, …

Resistance Training And Bone Mineral Density During Growth, M. Z. Smith, B. M. Goettsch, R. D. Van Ramshorst, J. A. O'Brien, S. V. Jaque, Ken D. Sumida

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

This study examined the efficacy of two different resistance training programs in enhancing bone modeling and bone mineral density (BMD) in maturating rats. One exercise mode involved lifting a lighter weight with more repetitions (LI), while the other regimen involved lifting a heavier weight with fewer repetitions (HI) where the total volume of work between exercise programs was equivalent by design. Twenty-three male rats were randomly divided into control (Con, n = 8), LI (n = 7), and HI (n = 8) groups. The LI and HI groups were conditioned to climb a vertical ladder with weights appended to their …

Interrupted Vs. Uninterrupted Training On Bmd During Growth, B. M. Goettsch, M. Z. Smith, J. A. O'Brien, G. V. Gomez, S. V. Jaque, Ken D. Sumida

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

This study compared a resistance training program where the exercise was uninterrupted (UT, i.e., continuous repetitions) against a resistance training program where the exercise was interrupted (IT, i.e., 3 exercise sessions during a training day) for enhancing bone modeling and bone mineral density (BMD) in maturating animals. The total volume of work performed between the two resistance training programs was equivalent by design. 24 young male rats were randomly divided into Control (Con, n = 8), UT (n = 8) and IT (n=8) resistance trained groups. The UT and IT groups were conditioned to climb a vertical ladder with weights …

Invited Review: Heat Shock Proteins And Exercise: A Primer, Earl Noble, Kevin Milne, C.W. Melling

Jamie Melling

Heat shock proteins (HSPs) are, in general, prosurvival molecules within the cellular environment, and the overexpression of even just 1 family of HSPs can lead to protection against and improvements after a variety of stressors. Not surprisingly, a fertile area of study has grown out of effors to exploit the innate biologic behaviour of HSPs. Exercise, because of the inherent physiologic stresses associated with it, is but 1 stimulus that can result in a robust increase in various HSPs in several tissues, not the least of which happen to be the heart and skeletal muscle. The purpose of this review …
