Accuracy of Self-Reported Height, Weight, and Calculated BMI and Resulting FITNESSGRAM® Healthy Fitness Zone Classification

Access: Use of this item is restricted to the UNT Community
The determination of adiposity in adolescents is often assessed with calculations of body mass indices (BMI). Researchers often obtain these measurements from self-reported (SR) values. The purpose of this study was to determine the accuracy of SR height, weight, and calculated BMI (from height and weight). SR and actual measured (ME) BMI values were compared with standards from the FITNESSGRAM® Healthy Fitness Zone (HFZ) classifications. SR height and calculated BMI were found to be accurate while SR weight was, on average, underreported by 4.77 lbs. Because of these errors in SR height and weight, accuracy of classification into the FITNESSGRAM® HFZ was compromised. Consequently, it is important that researchers ascertain actual values of height and weight when measuring adolescents rather than use those from self-reports.

ADA Compliance and Accessibility of Aquatic Facilities in the North Texas Area (open access)

ADA Compliance and Accessibility of Aquatic Facilities in the North Texas Area

The purpose of this study was to determine the degree to which existing aquatic facilities in the North Texas metroplex complied with the 1991 Americans with Disabilities Act Accessibility Guidelines (ADAAG) and the proposed Americans with Disabilities Act Accessibility Guidelines: Recreation Facilities (ADAAG supplement). Fifty-two aquatic facilities were evaluated based on: parking lot, ticket counter, gate/entry, restroom, dressing area, drinking fountain, pathway, and pool entry method structural domains. Physical measurements and a few direct observations were recorded on the survey instrument. Surveys were then reviewed and facility scores were tabulated. No facility was found to be 100% compliant with ADAAG and the ADAAG supplement. Aquatic facilities are already struggling to catch up with the 1991 ADAAG, but when the United States Department of Justice approves the proposed ADAAG supplement, aquatic facilities will fall even further behind.

Assessment and Comparison of  the Stress Experienced by International and American Students at the University of North Texas (open access)

Assessment and Comparison of the Stress Experienced by International and American Students at the University of North Texas

There were two purposes of the current study: (1) to evaluate if the East Asian Student Stress Inventory could be used to assess the stress experienced by International and American students at the University of North Texas and (2) to determine if the Inventory could discriminate between the two groups on the basis of the stress assessment. A sample of International (n=205) and American (n=216) graduate and undergraduate students completed the inventory. Results indicated that the EASSI could be generalized to a wider spectrum of International students. Using principal component factor analysis with varimax rotation, eight factors were extracted: culture shock, physiological symptoms, family pressure, test anxiety, financial difficulties, attitude toward study, social support and academic self esteem. The inventory clearly discriminated between the two groups on the subscales of culture shock, family pressure and attitude toward study and the International students scored higher on these subscales.

Attentional Focus Strategies of Multi-Sport Athletes. (open access)

Attentional Focus Strategies of Multi-Sport Athletes.

The purpose of this study was to determine (a) the attentional focus strategies used by triathletes during the three stages of an Olympic distance triathlon, (b) if level of experience influences the attentional focus strategies used by triathletes, and (c) whether there is a relationship between athletes finishing times and the attentional strategies used in each stage of the race. Triathletes (N = 160) completed the Triathlon Attentional Focus Inventory, which measured association and dissociation during the swim, bike, and run. One-way ANOVAs revealed significant differences between the athletes' level of experience and the attentional strategies used, as well as differences between the athletes overall race time and the attentional strategies used during each stage of the triathlon. Athletes with more experience associated more during the race, whereas athletes with less experience dissociated more throughout the race.

Attitudes and Behaviors Toward Weight, Body Shape and Eating in Male and Female College Students (open access)

Attitudes and Behaviors Toward Weight, Body Shape and Eating in Male and Female College Students

The purpose of this investigation was to assess the association between body mass index as well as race/ethnicity and established correlates of disordered eating including drive for thinness, body dissatisfaction, bulimia, dietary restraint and social physique anxiety in male and female college students. Difference between actual, desirable and perceived body weight was also assessed. ANOVA suggested that as actual body mass index increased, in general, attitudes and behavior toward weight, body shape and eating increased. A two-tailed t-test suggested that males and females differed significantly with regards to attitudes and behavior toward weight body shape and eating. ANOVA indicated that little to no association existed between race/ethnicity and established correlates of disordered eating.

Body Ideals and Weight Bias: Does Ethnicity Make a Difference? (open access)

Body Ideals and Weight Bias: Does Ethnicity Make a Difference?

The current study investigates whether there are there ethnic differences between Caucasian, African American, and Hispanic women in (a) weight bias, (b) body ideals, (c) social awareness and internalization of appearance standards and (d) physical activity in relation to these constructs. Participants included 130 Caucasian, 103 African American, and 52 Hispanic undergraduate female students. Participants completed a demographic survey, the Antifat Attitudes Test, the Figure Rating Scale, the Sociocultural Attitudes toward Appearance Questionnaire, and the Multiethnic Identity Measure questionnaire. No significant ethnic group differences in weight bias emerged. Differences were found for participants' perceptions of the culturally ideal female body shape, as well as awareness and internalization. No relationship was found between physical activity and weight bias, body ideals, and appearance standards. Future researchers should use health weight classifications, in addition to ethnicity, to examine weight bias, body ideals, and physical activity.

Coaching Behavior Preferences of Interscholastic Athletes (open access)

Coaching Behavior Preferences of Interscholastic Athletes

The purpose of this study was to determine whether coaching behavior preferences of interscholastic athletes differ as a function of gender and type of sport. The Coaching Behavior Questionnaire (CBQ; Martin & Barnes, 1999) was administered to 372 interscholastic athletes. The mean scores of the participants' responses to each subscale on the CBQ were the dependent variables and gender and type of sport were the independent variables. Descriptive statistics revealed that female and male interscholastic athletes who perform on coactive, mixed, and interactive sport teams preferred coaches who engage in supportive and instructional behaviors, as opposed to non-responses or negative responses. A 2 (Gender) X 3 (Type of Sport) MANOVA and discriminant function analyses indicated that gender and the degree of interdependency between group members affects preferred coaching behavior. Thus, coaches should consider situational factors and personal characteristics when working with interscholastic athletes.

The Construct Validity of Self-Reported Historical Physical Activity

Access: Use of this item is restricted to the UNT Community
The purpose of this study was to determine the construct validity of self-reported historical walking, running, and jogging (WRJ) activity. The criterion measure was concurrent performance on a maximal treadmill test. Subjects completed a medical exam and treadmill test between the years 1976 and 1985, and completed a follow-up questionnaire in 1986. Questionnaire included an item that assessed WRJ for each year from 1976 through 1985. Data analysis included Spearman correlations, partial correlations, ANOVA, and ANCOVA. Results indicated self-reported historical WRJ can be assessed with reasonable validity when compared with concurrently measured treadmill performance, and there is no decay in the accuracy of this reporting for up to ten years in the past.

Effect of Chronic Alcohol Abuse and Resistance Training on the Skeletal Muscle Androgen Receptor Concentration of Rats

Access: Use of this item is restricted to the UNT Community
The purpose was to examine the effect of chronic alcohol abuse on the androgen receptor content (AR) in skeletal muscle, and to determine if this effect was influenced by resistance training. Thirty-four male rats (456 ± 1 g; mean ± SE) were divided into 4 groups: Sham exercise-Ethanol, Sham exercise-Normal diet, Exercise-Ethanol, and Exercise-Normal diet. Both Exercise groups underwent a 6-week "squat" resistance training protocol and both Ethanol groups received an alcohol-rich diet throughout the 6-week period. Western blot analysis showed no effect of alcohol or resistance training on the AR of the extensor digitorum longus. For the rectus femoris, alcohol caused a decline in the AR (p=0.01). This reduction was not attenuated by resistance training. The AR of the soleus was not affected by chronic alcohol abuse alone; however, the resistance training induced increase in the AR was prevented by chronic alcohol abuse (p=0.03).

The Effect of Mode and Intensity on Vo2 Kinetics in the Severe Intensity Domain (open access)

The Effect of Mode and Intensity on Vo2 Kinetics in the Severe Intensity Domain

The purpose of this study was to evaluate the effect of mode and intensity on VO2 kinetics in the severe intensity domain. Seventeen participants completed 3-7 tests each on a cycle ergometer and treadmill. For each test, Tfatigue, VO2max, Tmean response, VO2GAIN, TVO2max and T@VO2max were determined. Linear regression techniques were used to describe the relationship between TVO2max and Tfatigue . VO2max values were higher in running. The VO2 response profile was faster for running than cycling and faster at higher intensities. The faster VO2 response in running may be associated with larger active muscle mass or differences in muscle activation patterns. The faster response at higher intensities may suggest that VO2 response is driven by O2 demand.

The Effect of Steroid Dose Regimen on the Relationship Between Lower Extremity Muscle Function and Cardiac Function in Post Heart Transplant Patients

Access: Use of this item is restricted to the UNT Community
Differences in cardiovascular/aerobic function in heart transplant patients might be attributed to the rate of corticosteroid withdrawal and/or to skeletal muscle function. This hypothesis was tested among nine male, cardiac transplant recipients. Prednisone dosage was monitored, and isokinetic strength testing was performed at 4 different time periods throughout the first year post-transplantation. Cardiovascular/aerobic measurements were obtained at the fourth time period. Pre-surgery characteristics were obtained from the patient's medical record. Significant Pearson-product moment correlations were only found between muscle function and aerobic function and between pre-surgery characteristics and cardiovascular/aerobic performance. The results of this study show no evidence that rapid reduction of prednisone dosage enhances aerobic function by benefiting skeletal muscle function.

The Effects of a College Human Sexuality Course on Students' Sexual Knowledge, Attitude, and Behavior.

Using an experimental-comparison group design, data were collected at the beginning and end of a semester to assess the effect of a human sexuality course on students' sexual knowledge, sexual attitude, and sexual behaviors. Data analysis by t-tests showed statistical differences between the experimental and comparison group only on sexual knowledge scores ( p < .001), with the experimental group scoring higher. T-tests showed statistical difference between males and females in sexual attitude (p< .001) and sexual behavior (p< .001) with women scoring higher than men in the experimental group, and also when experimental and control groups were combined. Although not statistically significant, women scored higher in sexual knowledge than males.

The Effects of Biofeedback on Task Performance (open access)

The Effects of Biofeedback on Task Performance

This experiment attempted to study the effectiveness of biofeedback training on an individual's peak performance while performing a stress-provoking task. In a between subjects design 30 individual college students were divided into 2 groups. One group received auditory biofeedback and relaxation training, and the other group received no training. Both groups met the researcher for 1 hour a week for seven weeks. During each session the participant completed a ten-minute Competition and Coaction (C & C) computer software program (Shea, 1992). The biofeedback equipment recorded the physiological state of each of the participants while he/she performed the C & C task. Both groups' physiological values and C & C scores were compared using the SPSS software. The biofeedback group had statistically lower stress values than the non-biofeedback group (Schwartz, 1995). There was no statistical difference between the 2 groups' C & C scores. The STAI Y-1 and Y-2 anxiety inventories were given to each of the participants at the 1st and 7th session to examine the anxiety differences between the 2 groups. There were no statistical differences between the 2 groups' STAI scores. This study's findings show that individuals can be taught to lower their stress response while performing a …

The Effects of Motivational and Instructional Self Talk on the Attentional Focus of High School Distance Runners.

Access: Use of this item is restricted to the UNT Community
The purposes of this study were to examine the (a) attentional focus strategies used by high school distance runners, (b) changes in attentional focus across four laps in three 1.6 km runs, and (c) effects of a pre-performance intervention using motivational and instructional self talk on the attentional focus strategies used by and performance of high school distance runners. Participants (N = 42) completed a background and demographic questionnaire, the Cross Country Attentional Focus Inventory (CCAFI), a motivational and instructional statement survey, and the Self-Motivation Inventory. A series of oneway ANOVAs revealed significant differences in the types of attentional strategies used by each group, as well as fluctuations in use of strategies. The experimental group associated more during the each of the 1.6 km trials, whereas the control group dissociated more throughout each trial. A significant group by week interaction was found, with the experimental group maintaining their performance and the control group slowing from week one to week three.

Exploring flow among Division I and intramural athletes. (open access)

Exploring flow among Division I and intramural athletes.

This study explores the flow experiences of collegiate athletes. NCAA Division I athletes and intramural athletes (N = 180) completed a series of measures on their flow experiences. Comparisons were made regarding the characteristics of flow, the perceived facilitators of flow, the frequency of flow experiences, and explored the role of perceived ability. Using a person by situation interaction framework, this study singles out perceived ability as a person factor and competitive level as a situational factor to more clearly examine flow experiences. Results indicated distinctions between the two groups. Mainly, the intramural athletes reported experiencing the merging of action and awareness, autotelic experience, transformation of time and having clear goals more frequently than the NCAA Division I athletes. No group differences were found for flow frequency or flow facilitators. Perceived ability was found to have a weak, but significant relationship with specific flow facilitators and characteristics.

Factors related to cycling performance (open access)

Factors related to cycling performance

There were two primary goals in this investigation. The first goal was to determine if results from field tests (time-trials and a Conconi incremental test) are related to performance in mass-start long-distance bicycle races. The second goal was to investigate inter-relationships among field test variables. The testing variables measured were critical velocity (CV), Conconi anaerobic threshold (AT) velocity, 4mM AT velocity, fatigue index, peak blood lactate, and anaerobic work capacity. Participants were USCF 30 category 1 through 5 cyclists. Participants performed one 20.75 km and two 10.37 km all-out tests in the field. They also performed an incremental test. The tests were performed at one-week intervals. Results from the field tests were compared to recent mass-start racing performance. Results indicated that Conconi AT velocity was related to performance in a 161-km race. There was also a relationship between 4mM AT velocity and CV and between Conconi AT velocity and 4mM AT velocity. It was concluded that field tests might provide information about performance ability in mass-start long-distance bicycle races.

Identifying Changes in Resilience during Rehabilitation from a Spinal Cord Injury (open access)

Identifying Changes in Resilience during Rehabilitation from a Spinal Cord Injury

The study purposes were to identify changes in resilience, satisfaction with life (SWL), depression, spirituality, and functional independence (FI) and to examine the relationship between these variables, during the inpatient rehabilitation for a spinal cord injury (SCI). The sample included 42 individuals with a SCI, 33 males and 9 females, who were inpatients with a mean stay of 52 days (SD = 15.78). A repeated measures design was employed with questionnaires completed at three times during rehabilitation. Results indicated that there were significant changes in depression, satisfaction with life, spirituality, and FI during inpatient rehabilitation. Findings also indicated significant correlations between resilience, SWL, spirituality, and depression. Future studies developing interventions, and examining factors that predict resilience could help build resilience and may improve rehabilitation outcomes.

Minimum levels of physical activity and perceived quality of life. (open access)

Minimum levels of physical activity and perceived quality of life.

The purpose of this study was to examine the association between engaging in minimum levels of physical activity as defined by ACSM and perceived quality of life. A total of 43 college students were included in a repeated measures, quasi-experimental design research study that produced an overall retention rate of 65%, which resulted in 15 students being placed in the treatment group, and 28 students being placed in the control group. Analysis of variance with repeated measures was used to compare the quality of life mean scores over three administrations of the Quality of Life Inventory (QOLI), which resulted in no significant main effects for either the time measure or the group measure, but did produce a significant interaction effect. Post hoc analyses showed there was a significant difference between the treatment and control groups' quality of life mean scores only during the second administration of the instrument. Further analysis showed that the control group had significantly higher quality of life domain scores for six of the 16 quality of life domains. There were no significant differences between groups across any of the physiological measures. These findings did not support previous research that increasing individuals' level of physical activity will …

NCAA Division I Athletes Preferences for Coaching Behaviors

The purpose of this study was to determine whether coaching behavior preferences of NCAA Division I athletes differ as a function of gender and type of sport. The Coaching Behavior Questionnare (CBQ; Martin & Barnes, 1999) was administered to 195 NCAA Division I athletes. Gender and sport type were the independent variables and the participant's mean scores for the subscales on the CBQ were the dependent variables. Descriptive statistics revealed that, overall, NCAA Division I athletes prefer positive and instructional behaviors more than non-responses or negative behaviors. A 2 (gender) x 3 (type of sport) MANOVA and follow-up discriminant function analysis indicated that coaching behavior preferences differed as a function of gender and type of sport played. Thus, NCAA Division I coaches should consider both individual and situational characteristics when working with their athletes to achieve the desired outcome.

Oxygen Uptake Kinetics in Severe Intensity Exercise (open access)

Oxygen Uptake Kinetics in Severe Intensity Exercise

The purpose of this study was to describe mathematically the oxygen uptake kinetics during cycle ergometry, and to examine the effect of intensity on the kinetic responses within the severe domain. Sixteen volunteers performed a series of exercise tests at a range of intensities selected to elicit fatigue in ~3 to 10 min. A simple mono-exponential model effectively described the response across all intensities. There was a positive correlation between the response time and the time to fatigue, demonstrating that the maximal oxygen uptake was achieved faster at higher intensities within the severe domain. Models incorporating two components effectively described the responses only in tests lasting 8 min or more. It was concluded that there is a second, slow component in the oxygen uptake response only at the lower intensities within the severe domain.

Perceived Submaximal Leg Extension Forces of Young Adult Males

Access: Use of this item is restricted to the UNT Community
The purpose was to examine actual force (AF) productions of males for accuracy during leg extensions when given a random desired force (DF) ranging from 10-90% of maximal force (MF). Thirty males ranging from 18 to 30 years of age (M = 21.99 + 3.04), who had no previous experience with the test equipment, went through 9 randomly ordered submaximal efforts followed by a maximal effort. Correlations between AF and DF were high (r > .79) and test-retest was consistent between AF (r = .87) and MF (r = .90). Participants consistently undershot DF on both test and retest from 20-90% and overshot DF only at 10%. Power functions revealed exponents of less than 1, indicating that AF grows slower then DF for both test .70 (.95 CI = .63 - .77) and retest .66 (.95 CI = .60 - .73). The results replicate a prior study by Jackson, Martin, Koziris, Ludtke, and Dishman (2001) that used incremental rather than random increases in DF.

Primary Caregiving Father's Perceptions of Leisure (open access)

Primary Caregiving Father's Perceptions of Leisure

The purpose of this study was to evaluate the impact the primary caregiving role had on men's perceptions of leisure. The Assessment of Leisure and Recreation Involvement (Ragheb, 2002) was used to examine men's leisure. Twenty-five stay-at-home dad groups were solicited via e-mail; 81 men submitted usable responses to an online survey. Respondents considered themselves the primary caregiver for children in the household and at least one child was younger than 12. Descriptive data were collected about the experience of being a primary caregiving father, demographics, and how the caregiving role affects the men's perceptions of leisure. Caregiving fathers in the sample resembled the perceptions of many primary caregiving mothers. Perhaps the "caregiving" role, rather than gender, is a more distinct variable explaining perceptions of leisure by parents.

The Relationship Among Gender, Gender Role Attitudes, and the Anticipated Commitment to Career, Marriage, Family, and Housework

The relationships between gender, gender role attitudes, and participants' anticipation of future life roles (career, marriage, family, and homecare) were examined. Participants consisted of 297 single college students between the ages of 17-29 years (M = 20). Females reported significantly (p< .01) more egalitarian gender role attitudes than males. Significant results were found for the relationship between gender and anticipated life roles (p< .01) as well as between gender role attitudes and anticipated life roles (career role value, r = .14 and marital role value, r = - .18). The study findings suggest a possible gender conflict for females with more egalitarian gender role attitudes and behavior intentions and their male counterparts.
