The Influence Of Tissue Plasminogen Activator I/D Polymorphism On The Tpa Response To Exercise, Adam M. Coughlin
The Influence Of Tissue Plasminogen Activator I/D Polymorphism On The Tpa Response To Exercise, Adam M. Coughlin
International Journal of Exercise Science
International Journal of Exercise Science 11(3): 1136-1144, 2018. The purpose was to determine if the Alu-insertion (I)/deletion (D) polymorphism of the tissue plasminogen activator (tPA) gene influences the tPA response to maximal exercise. Fifty male subjects (age = 23.6 ± 4.7 yrs) completed a maximal treadmill exercise test. Blood samples were drawn before and immediately after exercise for determination of plasma tPA antigen and activity. Isolated DNA was amplified via polymerase chain reaction, electrophoresed, and visually amplified to determine tPA genotype. Subjects were classified as possessing the D allele (D) (n = 28) or being homozygous for the I allele …

Technology-Based Physical Activity Self-Monitoring Among College Students, Zack Papalia, Oliver Wilson, Melissa Bopp, Michele Duffey
International Journal of Exercise Science
International Journal of Exercise Science 11(7): 1096-1104, 2018. Understanding the relationship between college students’ physical activity (PA) self-monitoring and PA levels has the potential to inform initiatives to promote PA. This study’s purpose was to examine the prevalence of technology-based self-monitoring among college students the potential relationship between device usage, goal setting behaviors, PA enjoyment, and PA levels. An online survey assessed students' demographics, current PA level, technology-based PA self-monitoring, and psychosocial outcomes. Independent t-tests examined differences in PA level and psychosocial outcomes by device use. 55.5% of the final sample (N=1,154) reported technology-based self-monitoring. Mobile phone app-based PA tracking …
Fitness Profiles In Elite Tactical Units: A Critical Review, Daniel Maupin, Thomas Wills, Robin M. Orr, Benjamin Schram
Fitness Profiles In Elite Tactical Units: A Critical Review, Daniel Maupin, Thomas Wills, Robin M. Orr, Benjamin Schram
International Journal of Exercise Science
International Journal of Exercise Science 11(3): 1041-1062, 2018. Elite tactical units complete a variety of demanding tasks and a high level of fitness is required by this population to perform their occupational tasks optimally. The aim of this critical review was to identify and synthesize key findings of studies that have investigated the fitness profiles of elite tactical units. Included studies were critically appraised, using the Downs and Black checklist, and a level of evidence was determined. Relevant data were extracted, tabulated, and synthesized. Fourteen studies were included for review and ranged in percentage quality scores from 46% to 66% …
Comparison Of Physical Activity During Zumba With A Human Or Video Game Instructor, Bridgette Schneekloth, Gregory A. Brown
Comparison Of Physical Activity During Zumba With A Human Or Video Game Instructor, Bridgette Schneekloth, Gregory A. Brown
International Journal of Exercise Science
International Journal of Exercise Science 11(4): 1019-1030, 2018. Using a physically active video game presents an opportunity for a person to engage in exercise in the privacy of their own home, yet still receive some feedback on the quality of their exercise performance. The purpose of this project was to compare the physical activity between participating in a Zumba exercise class led by a human and using a Zumba video game. Eight women (33.0 ± 3.0 y, 34.8 ± 8.1 % body fat) who regularly participated in a Zumba exercise class were measured for heart rate, number of steps taken, …
A Two-Test Protocol For The Precise Determination Of The Maximal Lactate Steady State, Daniel Yaeger, Jena Winger, Kristin Murphy, Stasinos Stavrianeas
A Two-Test Protocol For The Precise Determination Of The Maximal Lactate Steady State, Daniel Yaeger, Jena Winger, Kristin Murphy, Stasinos Stavrianeas
International Journal of Exercise Science
International Journal of Exercise Science 11(4): 681-695, 2018. The purpose of this study was to determine the efficacy of a two-test method for precisely identifying the Maximal Lactate Steady State (MLSS). Eight male competitive cyclists performed two bouts on a cycle ergometer. Following a maximal oxygen consumption (O2max) test (66.91 ± 5.29 mL∙kg-1∙min-1) we identified the lactate deflection point using the visual deflection (TVis), Log-Log (TLog), Dmax (TDmax), RER = 1.00 (TRER), ventilatory threshold (TVent), and the 1.0 mmol·L-1 increase above baseline …
Behavior Change Techniques And Physical Activity Using The Fitbit Flex®, Emily E. Dunn, Jennifer Robertson-Wilson
Behavior Change Techniques And Physical Activity Using The Fitbit Flex®, Emily E. Dunn, Jennifer Robertson-Wilson
International Journal of Exercise Science
International Journal of Exercise Science 11(7): 561-574, 2018. Due to the availability of low-cost accelerometers, there has been an increase in the adoption of physical activity monitors (e.g., Fitbit®) (14) accompanied by a desire to understand the behavior change techniques (BCTs; 15) present in such monitors. One specific Fitbit® monitor incorporates 20 BCTs (15), but how users experience these BCTs has yet to be explored. The purpose of this study was to explore user’s experience with the Fitbit Flex® regarding physical activity behavior and BCTs. The specific research objectives were to: 1) describe Fitbit Flex® users and 2) explore user’s …
Practices, Perceived Benefits, And Barriers To Strength Training Among Women Enrolled In College, Kimberly S. Hurley, Kaleigh J. Flippin, Lindsey C. Blom, Jocelyn E. Bolin, Donald L. Hoover, Lawrence W. Judge
Practices, Perceived Benefits, And Barriers To Strength Training Among Women Enrolled In College, Kimberly S. Hurley, Kaleigh J. Flippin, Lindsey C. Blom, Jocelyn E. Bolin, Donald L. Hoover, Lawrence W. Judge
International Journal of Exercise Science
International Journal of Exercise Science 11(5): 226-238, 2018. The American College of Sports Medicine (ACSM) has recommended that resistance training be performed at least twice per week, with 8-12 repetitions of 8-10 exercises targeting all major muscle groups (1). However, Kruger, Carlson, and Kohl (18) reported that women were participating less than the U.S. population on the whole, as only 20% of women were engaging in resistance training two or more times per week. In order to better understand why only 1 in 5 women participate regularly in this form of physical activity, this study investigated current resistance training practices, …

Discrimination Against Obese Exercise Clients: An Experimental Study Of Personal Trainers, Fabio Fontana, Jonathan Bopes, Seth Bendixen, Tyler Speed, Megan George, Mickey Mack
International Journal of Exercise Science
International Journal of Exercise Science 11(5): 116-128, 2018. The aim of the study was to compare exercise recommendations, attitudes, and behaviors of personal trainers toward clients of different weight statuses. Fifty-two personal trainers participated in the study. The data collection was organized into two phases. In phase one, trainers read a profile and watched the video displaying an interview of either an obese or an average-weight client. Profiles and video interviews were identical except for weight status. Then, trainers provided exercise recommendations and rated their attitude toward the client. In phase two, trainers personally met an obese or an average-weight …

Six Weeks Of Moderate Functional Resistance Training Increases Basal Metabolic Rate In Sedentary Adult Women, Jon Stavres, Mcauley P. Zeigler, M. Pasternostro Bayles
International Journal of Exercise Science
International Journal of Exercise Science 11(2): 32-41, 2018. Basal metabolic rate (BMR) is a significant contributor to total daily energy expenditure. Traditional resistance exercise has been shown to elicit fat free mass (FFM) related increases in BMR. The purpose of this study was to examine the effect of a functional resistance exercise program on the BMR of a group of previously sedentary adult women in a free-living condition. 19 sedentary, apparently healthy women underwent body composition analysis and had BMR assessed before and after a 6-week functional resistance training program. The resistance training program was designed to be progressive in …
