Effect Of Actigraph's Low Frequency Extension For Estimating Steps And Physical Activity Intensity, Yuri Feito, Lyndsey M. Hornbuckle, Lauren A. Reid, Scott E. Crouter

Faculty Articles

This study examined the effects of the ActiGraph’s (AG) low-frequency extension (LFE) filter on steps and physical activity classification in the free-living environment. Thirty-four African-American women (age, 24.5±5.2 years; BMI, 24.9±4.5 kg/m2) had daily activity measured simultaneously with an AG-GT3X+ accelerometer and a New Lifestyles NL-800 pedometer for seven days. Steps per day (steps/day) and time (minutes/day) spent in sedentary, light, and moderate-to-vigorous physical activity (MVPA) were examined with and without the LFE filter (AG-LFE and AG-N, respectively). The AG-LFE recorded more total steps (13,723±4,983 steps/day) compared to AG-N and NL-800 (6,172±2,838 and 5,817±3,037 steps/day, respectively; p<0.001). Compared to the AG-N, the AG-LFE estimated less time in sedentary behaviors (518.7±92.1 vs. 504.2±105.4 min/day, respectively; p<0.001), and more time in light (247.7±70.4 vs. 279.1±74.7 min/day, respectively; p<0.001) and MVPA (18.9±16.9 vs. 21.5±18.2 min/day, respectively; p<0.001), respectively. These data suggest that steps and physical activity classifications will be affected when using the ActiGraph with and without the LFE filter. Future research should investigate the accuracy of these measures using the LFE filter.

Effects Of Heat Exposure On Body Water Assessed Using Single-Frequency Bioelectrical Impedance Analysis And Bioimpedance Spectroscopy, Brett S. Nickerson, Michael R. Esco, Phillip A. Bishop, Brian M. Kliszczewicz, Henry N. Williford, Kyung-Shin Park, Bailey A. Welborn, Ronald L. Snarr, Danilo V. Tolusso

International Journal of Exercise Science

International Journal of Exercise Science 10(7): 1085-1093, 2017. The purpose of this study was to determine if heat exposure alters the measures of total body water (TBW), extracellular water (ECW), and intracellular water (ICW) in both single-frequency bioelectrical impedance analysis (BIA) and bioimpedance spectroscopy (BIS). Additionally, we sought to determine if any differences exist between the BIA and BIS techniques before and after brief exposure to heat. Body water was evaluated for twenty men (age=24±4 years) in a thermoneutral environment (22°C) before (PRE) and immediately after (POST) 15 min of passive heating (35°C) in an environmental chamber. The mean difference …

The Relationship Between Athletic Identity And Academic Major Chosen By Student-Athletes, Sayvon Jl Foster, Matt R. Huml

International Journal of Exercise Science

International Journal of Exercise Science 10(6): 915-925, 2017. This study examines the correlation between athletic identity and academic major selection among intercollegiate student-athletes. A thorough review of literature focusing on academic clustering, athletic identity, and academic development leads to the development of two hypotheses – 1) student-athletes with stronger athletic identity will have a declared major of decreased academic rigor; and 2) student-athletes with stronger athletic identity will be more likely to be undecided on their major. Data were collected through a survey administered to Division I, II, and III student-athletes recording academic major and their Athletic Identity Measurement Scale …

Corporate Social Responsibility: Considerations For Sport Management In The Age Of Neoliberalism, Anthony J. Weems, Justin R. Garner, Kristi Oshiro, John N. Singer

International Journal of Exercise Science

International Journal of Exercise Science 10(6): 900-914, 2017. For financial reasons, in efforts to maintain legitimacy, and in response to social pressures, sport organizations increasingly engage with corporate social responsibility (CSR). However, with the rise of global neoliberalism, the logic of CSR can be problematic. In this essay, we provide a brief overview, critique, and reconstruction of CSR in the sport industry. Specifically, we call into question three popularized forms of CSR: (1) diversity, inclusion, and diversity management, (2) environmental responsibility, and (3) health and physical activity-based initiatives. In a neoliberal context, CSR in sport provides, at best, a limited …

From Crisis To De-Escalation: An Examination Of Politics In A U.S. High School Steroid Testing Program, Brennan K. Berg, Kathryn Winsley, Rhema D. Fuller, Michael Hutchinson

International Journal of Exercise Science

International Journal of Exercise Science 10(6): 890-899, 2017. Preventing the use of performance enhancing drugs in sport has long been a concern for policymakers. In the United States, amidst national attention the state of Texas constructed the country’s largest steroid testing program for high school athletes. However, resource allocation steadily declined until the program was defunded in 2015. Using escalation of commitment theory as a framework, this conceptual paper examines the critical, but less studied, role of politics and de-escalation behavior that directed this distinct sport situation. By combining policy and media documents with the academic literature, this paper allows …

Coaches’ Perception Of Organizational Socialization Process Of International Student-Athletes And The Effect Of Cultural Distance: An Exploratory Study., Evelyn S. Jara-Pazmino, Bob Heere, Tom H. Regan, Christine E. Blake, Richard Southall

International Journal of Exercise Science

International Journal of Exercise Science 10(6): 875-889, 2017. This study focuses on the coaches’ perspective of the organizational socialization process of new international student-athletes. After analyzing the information of 10 in-depth interviews with experienced NCAA Division I coaches, this exploratory study aided the researchers to identify socialization tactics being used to successfully integrate international student-athletes entering USA college teams. ISAs come from different cultures, and pending on their home nation culture they might be challenged in their ability to socialize within their new surroundings. Results indicate that the cultural distance between team culture and ISA’s culture affects the effectiveness of …

Cultural Values And Gender Equity On National Olympic Committee Boards, Na Young Ahn, George B. Cunningham

International Journal of Exercise Science

International Journal of Exercise Science 10(6): 857-874, 2017. Women are under-represented in leadership positions throughout sport, and researchers have largely explored organizational, group, and individual antecedents of this phenomenon. The purpose of the current study was to expand on this understanding by investigating the influence of a country’s cultural values on the representation of women on National Olympic Committees. Drawing from Hofstede’s cultural dimensions theory, the authors included five cultural values: power distance, uncertainty avoidance, individualism-collectivism, masculinity-femininity, and long-term orientation. Results indicate that women constituted only 19.7 percent of the positions on the boards. Regression analysis, controlling for size of …

“I Will Change The World”: The Intersection Of Social Change And Male College Athletes’ Leadership Perspectives, Rhema D. Fuller, C. Keith Harrison, S. Malia Lawrence, Jeff Eyanson, Danielle Mccardle

International Journal of Exercise Science

International Journal of Exercise Science 10(6): 845-856, 2017. Historically, men have been characterized as task-oriented leaders who are motivated by desires for autonomy, wealth, and power (17, 33). However, these “masculine” views of leadership might not accurately capture the leadership motivations of Millennial males as the views were developed in previous generations (4). Given the commitment of many Millennials towards socially responsible attitudes and behaviors (18, 25), we utilized a qualitative research design to examine the influence of social change on the leadership motivations of Millennial male intercollegiate athletes. In doing so, we found participants were motivated to lead in …

Are You Welcomed? A Racial And Ethnic Comparison Of Perceived Welcomeness In Sport Participation, Trevor Bopp, Robert Turick, Joshua D. Vadeboncoeur, Thomas J. Aicher

International Journal of Exercise Science

International Journal of Exercise Science 10(6): 833-844, 2017. Sport has become racialized such that minority youth accrue limited health and academic benefits from participation, compared to their White counterparts. Understanding the welcomeness that minorities feel in sport, leisure and physical activities plays an important role in breaking down barriers to participation. Thus, the overall aim of this study is to further examine the determinants of sport participation, particularly as it relates to race, socialization and perceived welcomeness. College students (N = 451) scored their perceived level of welcomeness for Whites, African Americans and Hispanic/Latinos in 14 sports. Results reveal significant …

Does Time Heal All Wounds? A Case Study On Rival Perceptions Before And After Conference Realignment, Cody T. Havard, Daniel L. Wann, Timothy D. Ryan, Norman O'Neal

International Journal of Exercise Science

International Journal of Exercise Science 10(6): 823-832, 2017. The current longitudinal case study investigated how conference realignment and beginning new annual competitions impacted fan rival perceptions for fans of the Texas A&M Aggies, Missouri Tigers, and Texas Christian University Horned Frogs. In particular, fan rival perceptions before and after conference realignment were compared to determine if significant differences were present. Findings indicate that history plays an important role in rivalry as fans of teams sharing long-standing rivalries with schools in their previous conference (i.e., Texas A&M/Texas and Missouri/Kansas) did not differ in their rival perceptions before or after conference realignment. …

Effect Of Long-Term Beta-Alanine Supplementation On Performance In Male Collegiate Rugby Athletes, Charles Smith

Theses

This study investigated the effects of six weeks of beta-alanine (BA) supplementation on the anaerobic performance of collegiate male rugby players. Beta-alanine is a precursor to carnosine, an intramuscular buffer that helps maintain pH during high-intensity exercise. Rugby is a sport characterized by repeated bouts of high-intensity efforts, making it a prime candidate to benefit from improved buffering capacity.

Twenty-one male rugby players were recruited for the double-blind, placebo-controlled study, with 16 completing the post-testing. Participants were randomly assigned to either a beta-alanine group (6.4 g/day) or a placebo group (6.4 g/day of maltodextrin). Both groups continued their normal team …

Sport Commitment Among Adult Recreational Soccer Players: Test Of An Expanded Model, Amanda L. Frayeh, Beth Lewis

International Journal of Exercise Science

International Journal of Exercise Science 10(1): 4-24, 2017. Adult sport leagues provide opportunities for physical activity (PA), but little is known about adults’ commitment to recreational sports. We proposed two expanded versions of Scanlan and colleagues’ sport commitment model (SCM) to explore psychosocial factors related to adults’ participation in these leagues. Model 1 proposed athletic identity and social cohesion as additional predictors of commitment. Previous research found these variables to be positively related to commitment, but had not systematically examined them within the context of the SCM. We also explored participation in moderate-to-vigorous physical activity (MVPA) as a behavioral manifestation …

Physical Activity, Body Mass Index, And Clustered Metabolic Risk In U.S. Adolescents: 2007-2012 Nhanes., Bethany Dawn Williams

UNF Graduate Theses and Dissertations

Objectives: To examine variation in clustered metabolic risk (cMetS) in adolescents classified as not overweight/active (NOA), not overweight/not active (NONA), overweight/active (OA), and overweight/not active (ONA).

Background: While studies to date have shown that children and adolescents who meet the current physical activity (PA) recommendations and maintain a healthy body weight demonstrate significantly lower cardiometabolic risk, there are some studies that suggest the relationship between PA and metabolic risk may be mediated by adiposity.

Methods: The sample included adolescent participants (n=875; 12-17 years) of the 2007-2012 National Health and Nutrition Examination Survey (NHANES). The cMetS score included triglycerides, high-density lipoprotein …

Organizational Misconduct Within The National Collegiate Athletic Association, Khirey Bennie Walker

LSU Doctoral Dissertations

Prior research on organizational misconduct within intercollegiate athletics focuses on the penalties administered by the NCAA and types of violations committed by member institutions, rather than the engagement of misconduct and the role of the NCAA as a social-control agent. Consequently, the purpose of this dissertation is to analyze the relationship between social-control agents and potential wrongdoers (i.e., organizations), in addition to how the relationship affects the evolving line separating right from wrong. A three-paper multiple method examination has been conducted, including a historical analysis of NCAA enforcement, a qualitative framing analysis on the detailing of NCAA major infractions to …

The Effect Of A Moderately-Low And High Carbohydrate Intake On Crossfit Performance, Kurt A. Escobar, Jacobo Morales, Trisha A. Vandusseldorp

International Journal of Exercise Science

International Journal of Exercise Science 9(4): 460-470, 2016. CrossFit is a metabolically demanding strength and conditioning method which performance may benefit from a carbohydrate (CHO)-rich diet. This study investigated the effect of three consecutive days of high CHO intake on CrossFit performance and corresponding metabolically -related variables in strength trained individuals. Eighteen subjects with a CHO intake of <6 g/kg/day were randomly assigned into a CHO (n = 9) or control (C) group (n =9) and underwent a 9-day training protocol. During days 1, 5, and 9, performance was measured as repetitions completed during a 12 minute CrossFit workout. Oxygen consumption (VO2), respiratory exchange ratio (RER), and blood lactate (BL) were also measured. Days 6-8, the CHO group increased CHO intake from <6 g/kg/day to 6-8 g/kg/day; the C group maintained their current intake of <6 g/kg/day. On days 6 and 7 both groups performed CrossFit workouts followed by a day of rest prior to day 9. There was a significant increase in repetitions completed in both groups in day 9 (vs. means score of day 1 + 5) (p = 0.002), but no differences between C and CHO groups (p = 0.111). However, the CHO group displayed a 15.2 repetition increase (+10.9%) in day 9, compared to 5.7 (+4.2%) by the C group. VO2, RER, and BL were not influenced by the experimental intervention. Our results suggest that the CrossFit-embraced practice of moderately-low CHO diets may be adequate in CHO during short periods of training, however, given the noted trend, extended training periods may be effected.

The Effect Of Post-Resistance Exercise Amino Acids On Plasma Mcp-1 And Ccr2 Expression, Adam J. Wells, Jay R. Hoffman, Adam R. Jajtner, Alyssa N. Varanoske

Faculty Articles

The recruitment and infiltration of classical monocytes into damaged muscle is critical for optimal tissue remodeling. This study examined the effects of an amino acid supplement on classical monocyte recruitment following an acute bout of lower body resistance exercise. Ten resistance-trained men (24.7 ˘ 3.4 years; 90.1 ˘ 11.3 kg; 176.0 ˘ 4.9 cm) ingested supplement (SUPP) or placebo (PL) immediately post-exercise in a randomized, cross-over design. Blood samples were obtained at baseline (BL), immediately (IP), 30-min (30P), 1-h (1H), 2-h (2H), and 5-h (5H) post-exercise to assess plasma concentrations of monocyte chemoattractant protein 1 (MCP-1), myoglobin, cortisol and insulin …

The Effect Of Weighted Body Armor On Close Combat Reaction Time And Core Muscle Activation 2016, Christopher Banta

Master's Theses

The purpose of this study was to measure the choice reaction time and myoelectric activity of the right and left rectus abdominus, and right and left external obliques required to initiate movement in response to a visual stimulus that signaled performance of four different closecombat movements (left or right cross and left or right dodge). Reaction time and myoelectric activity were then compared with performing the movements in response to the visual stimulus while wearing a weighted vest that simulated wearing tactical body armor. Myoelectric activity was measured as the average root mean square (RMS) of the surface electromyography (sEMG) …

Assessing Clinical Significance Of The Immediate Post-Concussion Assessment And Cognitive Testing Battery When Comparing Adjusted And Unadjusted Rci Methods For Different Ranges Of Baseline Scores, Ashley N. Figaro

UNLV Theses, Dissertations, Professional Papers, and Capstones

The growing concern revolving around the dangers of sports-related concussions have led to the most recent implementation of neurocognitive (NC) test batteries as a means to objectively determine the presence of a cognitive defect. Whereas any other sports-related injury can be diagnosed with tools such as an x-ray or MRI, a concussion represents a metabolic disturbance that cannot be identified by these diagnostic tools. Many neurocognitive test batteries employ statistical techniques to derive cut off scores in order to represent significant or insignificant changes as compared to individual baseline scores, or pre-established normative values. If an individuals’ post-injury score exceeds …

Determining The Value Of Birthrank And Parent Age In Thoroughbred Racehorses, Xiurui Cui

Theses and Dissertations--Agricultural Economics

Thoroughbred racing is referred to as “the sport of Kings”, because historically it was a leisure activity of the upper-class. Thoroughbred breeding on the other hand has transformed from a hobby of the upper-class to a worldwide agricultural industry. With the deep involvement of the royal and rich in the Thoroughbred industry, the auction prices of horses are raised significantly at the top end of the market.

Research in the biological sciences suggests there exits correlations between dam age, foal birthrank, and the racing performance of Thoroughbred horses. This study first investigates how the market values these biological factors and …

With an aging demographic, and the abundance of physical inactivity in Canada, sport professionals need to understand how best to recruit and retain adults in sport and recreational activities, namely, golf leagues. Canadian golf league participants (N = 419; Mage = 62 years old) completed an online survey detailing their propensity to utilize a variety of information sources prior to making the decision to join a golf league. Results from a principal component analysis of a revised Information Sources Inventory, suggested that golfers in this sample were most likely to utilize Personal and Social sources of information associated with their …

The Effects Of Maturational Variation On The Performance Of Young Australian Footballers And Their Selection Into The Australian Football League's Talent Pathway, Ashley Cripps

Theses

Traditional player development pathways share a common goal, to identify and accelerate the development of talented adolescent players for senior competition. Players who gain selection into development programs gain greater access to experienced coaches, training facilities, support staff and competition. However, despite such advantages, research has shown that few players who gain initial selection into development pathways progress into professional senior competition. A major factor which potentially contributes to poor player retention in development pathways is the initial misidentification of talented athletes due to variations in biological maturity.

Earlier maturing individuals have been shown to be at a physical advantage …

Collegiate Coaches’ Knowledge Of The Female Athlete Triad In Relation To Their Characteristics, Jillian E. Frideres, Sue G. Mottinger, Jose M. Palao

Health & Human Performance Faculty Publications

The purpose of this study was to determine what coaches of female athletes know about the female athlete triad. The sample involved 472 NCAA Division I coaches of female athletes. The variables studied were coaches’ knowledge and confidence about the triad and coaches’ characteristics (coach’s gender, age, type of coach, degree held, years of experience in coaching females, continuing education participation specific to the triad and/or triad components, and sport coached). Coaches’ knowledge of the female athlete triad is higher for coaches who have received triad education. No differences regarding knowledge of the female athlete triad were found by gender, …
