Validation of The Physical Activity Interview With Third and Fifth Grade Children (open access)

Validation of The Physical Activity Interview With Third and Fifth Grade Children

This study investigated the validity of the Physical Activity Interview (PAI) for assessing children's self-reported physical activity. Third and fifth graders wore an accelerometer and were interviewed using the PAI to determine 12-hour recall accuracy for activity expressed as energy expenditure (EE). Caltrac estimates of EE for the 12-hour day (12-HEE) and activity EE were the validation criteria. 12-HEE correlations were significant (p<.001) between Caltrac and PAI for third (r=.79) and fifth grade (r=.80). Caltrac and PAI Total Activity were significant for fifth grade (r=.82, p<.001) but not for third grade (r=.36, p<.021). Analysis of tertiles based on the Caltrac demonstrated that the PAI significantly (p<.002) discriminated between activity levels for fifth graders but not for third. The use of PAI may be age-dependent.

Psychological Factors Related to Drug Use in College Athletes (open access)

Psychological Factors Related to Drug Use in College Athletes

The purpose of the present investigation was to compare the psychological factors related to drug use by college athletes on seven drug categories. A questionnaire was given to male and female Division I college athletes asking them about their use of drugs. The frequency, intensity and duration of use/non-use was used to divide subjects into high and low/nonuser categories. Dependent measures included the Profile of Mood States, Coopersmith Self-Esteem Inventory and questions assessing athlete stress. A multivariate analysis of variance(MANOVA) was conducted in a 2 x 2 (alcohol high/low, non-user x male/female) design to distinguish significant differences on the POMS and stress questions followed by univariate ANOVA's. A separate ANOVA was run on Coopersmith's Self-Esteem Inventory. Results indicated that high alcohol users scored significantly higher on anger, fatigue and vigor than low/non-users. Significant differences were found between males and females on the pressure felt from coaches to perform well.

The Effectiveness of a Cholesterol Reduction Intervention Program Among Female Employees in a Corporate Setting (open access)

The Effectiveness of a Cholesterol Reduction Intervention Program Among Female Employees in a Corporate Setting

Three cholesterol interventions were evaluated in a work-site setting to determine which was most effective in modifying physiological, behavioral, and knowledge measures related to total serum cholesterol. Of the 246 employees initially screened, 135 (55%) were identified as having elevated total serum cholesterol levels (>200 mg/dl) and were eligible for the study. Treatment consisted of either a six-session cholesterol reduction course requiring 30 days dietary monitoring, a six-session course without dietary monitoring, or an incentive only approach. Significant increases in cholesterol knowledge and dietary fiber consumption was found in both the education intervention with logging and intervention without logging groups. The results indicate that positive learning effects can take place in work-site settings and that such learning can lead to dietary changes that reduce the effects of high serum cholesterol.

Effects of Positive Verbal Reinforcement on the Four Underlying Factors in Intrinsic Motivation (open access)

Effects of Positive Verbal Reinforcement on the Four Underlying Factors in Intrinsic Motivation

The study examined the effects of positive verbal reinforcement on intrinsic motivation by determining differential effects over four multidimensions of Ryan's Intrinsic Motivation Inventory (IMI). Subjects (N=60) were 30 male and 30 female college students. The subjects were blocked by gender and randomly assigned to a positive verbal reinforcement group or a control group. The subjects received 10 trials on the stabilometer. The results of the study indicated that there were significant group differences for composite intrinsic motivation and for perceived competence; however, there were no significant gender differences found. Furthermore, no group differences were reported for the underlying factors of interest/enjoyment, effort, or pressure/tension.

Event Order in the Biathlon Does Not Have an Effect on Metabolic Response (open access)

Event Order in the Biathlon Does Not Have an Effect on Metabolic Response

The purpose of this study was to examine the effects of event order on a cycling(C)/running(R) or R/C biathlon. Eight experienced male biathlete/triathletes with a mean age of 24.9 + 4.6 yr formed the sample of the study. Results show no significant interaction effects on oxygen consumption peak, oxygen consumption during steady-state, ventilation, and heart rate when C/R or R/C are performed at 70% oxygen consumption peak for subsequent R and C respectively. These results seem to indicate that the biathlete/triathlete is efficient in both C and R to the extent that event order does not significantly interact with metabolic response in submaximal cycling and running.

The Effectiveness of an Exercise Intervention Program in Reducing Cardiovascular Risk Among Employees in a University Setting

Nine physiological measures were evaluated pre- to post-intervention on subjects participating in a university health promotion program over a seven-month period. Frequency of program attendance and choice of activity were also assessed. Of the 88 employees initially screened, most of the subjects were staff members (n=82, 93%),with a majority being female (n=68, 77%). Significant differences in physiological measures were found pre- to post-intervention between "higher" and "lower" cardiovascular risk participants, primarily due to the type of activity chosen. .The results indicate that health promotion programs at a university are an effective way to have an impact on employees in reducing their cardiovascular risk factors.

Aortic Baroreceptor Reflex Control of Blood Pressure: Effect of Fitness (open access)

Aortic Baroreceptor Reflex Control of Blood Pressure: Effect of Fitness

Aortic baroreflex (ABR) control of blood pressure was examined in 7 untrained (UT) and 8 endurance exercise trained (EET) young men. ABR control of blood pressure was determined during a steady state phenylephrine infusion to increase mean arterial pressure 10-15 mmHg, combined with positive neck pressure to counteract the increased carotid sinus transmural pressure, and low levels of lower body negative pressure to counteract the increased central venous pressure. Functioning alone, the ABR was functionally adequate to control blood pressure. However, ABR control of HR was significantly diminished in the EET subjects due solely to the decrease in the ABR sensitivity. The persistent strain from an increased stroke volume resulting from endurance exercise training could be the responsible mechanism.

Effects of Strength on Selected Psychomotor Performances of Healthy and Frail Elderly Females (open access)

Effects of Strength on Selected Psychomotor Performances of Healthy and Frail Elderly Females

The purpose of this study was to compare muscle strength and psychomotor performance measures in healthy (n = 18) and frail (n = 21) groups of elderly women utilizing movements requiring various amounts of strength and ballistic action. Subjects were community-dwelling females ranging in age from 66-92 years. Evaluations of functional assessment of motor skills and grip strength occurred. Psychomotor performance was measured through production of aiming movements on a Digitizing Tablet. RT, MT, and movement kinematics (e.g., peak velocity, deceleration, movement adjustments) were evaluated. Differences between groups were apparent in quantity and quality of movement. Healthy subjects were stronger and faster than frail subjects, producing smoother movements with fewer adjustments. Strength appears to differentially affect healthy and frail samples and merits further exploration.

Estrogen Replacement Therapy and its Association with Life Satisfaction of Women over Fifty (open access)

Estrogen Replacement Therapy and its Association with Life Satisfaction of Women over Fifty

This study analyzed the effects of estrogen replacement therapy (ERT), ethnicity, marital status, education level, maternal status and financial security on the perceived life satisfaction of women over fifty. Information was collected from 125 subjects at an independent school district. The instrument was adapted from a life satisfaction scale originally developed by B. Neugarten. Eight demographic items included ERT use, age, menopause status, marital status, educational level, ethnicity and perception of financial security. Statistical analysis consisting of one way analysis of variance, Student Newman-Keuls ad hoc procedure and multiple regression indicated an independent correlation between financial security and education level to life satisfaction scores. Neither ERT nor menopause status was correlated with perceived life satisfaction score of respondents.

Predicting Peak Oxygen Uptake from Ratings of Perceived Exertion During Submaximal Cycle Ergometry

The purpose of this study was to predict VO2pak using ratings of perceived exertion (RPE), heart rate (HR), and percent fat (PFAT). Subjects were males (n= 60) (PFAT, M SD = 14.4 6.1) and females (n= 67) (PFAT, M SD = 23.4 4.9) with ages ranging from 18 to 33 years. Subjects performed an incremental cycle ergometer protocol and RPE, HR and Vo2 were measured at each stage until VO2 ak was achieved. Mean RPE and HR at the submaximal workload of 100 watts were, (RPE100) M= 12.7 2.6 and (HR100) M= 146.924.7 respectively. Correlations (p< .001) with VO2p. were -.75 (PFAT), -.66 (HR100), -.67 (FIPE100). The multiple correlation using PFAT, HR100, and RPE100 as predictors of VO2pak was .83 (SEE= 5.28 ml-kg BW'smin"). Each predictor contributed to the correlation (p<.01). The results indicate that PFAT combined with exercise responses of RPE and HR provide valid estimates of VO2peak with a relatively small SEE.

Developing and Establishing the Reliability and Validity of the East Asian Student Stress Inventory (EASSI)

The primary purpose of this study was to develop and establish the reliability and validity of the East Asian Student Stress Inventory. Data was obtained from 235 East Asian students at the University of North Texas during the fall semester of 1992. The procedures used were a two-week interval test-retest for reliability, experts' assessment of test items for face validity, a factor analysis, a one-way analysis of variance (ANOVA), and Pearson's product-moment correlation coefficient for construct validity. Significance was set at the .05 level. The EASSI was identified as having moderately high reliability. High test anxiety, physiological symptoms, social support, financial difficulty, and culture shock were found to be constructs of the EASSI. Majority of independent variables in this study effectively identified stressors and stresses among East Asian students.

The Relationship Between Leisure and Perceived Burden of Spouse Caregivers of Persons with Alzheimer's Disease

The problem of this study was to better understand spouse caregivers' leisure involvement, experience, and barriers and their relationships with perceived burden. Thirty-six wife and 19 husband caregivers of persons with Alzheimer's disease and related disorders volunteered to participate in this study, either by mailed questionnaire or interview. Respondents were primarily female, white, with an average age of 72 years. The conclusions of the study were: (a) caregivers significantly reduce both their leisure involvement; (b) self-reported health, perceived social supports, income level, use of paid help, and leisure activity patterns are major factors associated with caregivers' leisure; and (c) leisure barriers are a significant contributor to caregivers' perceived burden. Recommendations were presented for caregivers, practitioners, and future study.

Relationship Between Mood State and Cognitive Strategies on Endurance Performance (open access)

Relationship Between Mood State and Cognitive Strategies on Endurance Performance

The present investigation examined the relationship between elated and depressed moods and dissociation, association, and positive self-talk strategies on endurance performance. Results showed a significant mood main effect with elated subjects performing longer than depressed subjects. Results also revealed a significant cognitive strategy main effect with positive self-talk and dissociation groups producing longer endurance times than association and control groups. A significant interaction between mood and cognitive strategy found that subjects in the positive self-talk and dissociation groups increased their performance time to a greater extent from the depressed to the elated condition than did subjects in the association and control groups. Results are discussed in terms of previous investigations of mood and cognitive strategies on physical performance.

The Effects of Project PACE on Adolescent Females' Physical Activity Readiness

This study evaluated the effects of Project PACE, a program designed to increase physical activity, on the physical activity level and selected psychosocial variables of sedentary adolescent females ages 12 to 18. Psychosocial variables included self efficacy, attitude, perception of barriers, perceived social support, and knowledge. Of the 69 participants, 40 were enrolled in the treatment group and 29 were enrolled in the control group at the start of the study. The only significant differences were found for attitudes towards physical activity at base line. Findings from this study suggest that implementation of Project PACE protocol in school settings may produce some positive effects, but no significant findings were detected.

Timed vs. Untimed Initiation Intervals and the Effects of Confidence on a Golf Putting Task

Low, moderate, and high handicap golfers, while wearing glasses with a blinder on the side, attempted 9 putts differing in length from 5 to 21 ft under timed (less than 3.5s from grounding of club to initiation of back swing) and untimed conditions in a counterbalanced design. Confidence ratings were taken prior to and following each putt. The results revealed a significant condition by handicap group interaction (p=.021). The lower handicap group had a more consistent and lower initiation interval duration than did the moderate and high handicap players. Post interviews determined that 33 of the 35 golfers felt more comfortable in the untimed condition. However, golfers' confidence levels were not significantly different in the untimed condition as compared to the timed condition.

Designing a Social Marketing Plan to Promote Hispanic Participation at Prostate Cancer Screenings (open access)

Designing a Social Marketing Plan to Promote Hispanic Participation at Prostate Cancer Screenings

Prostate cancer is the most commonly occurring cancer and the second leading cause of cancer death for men in the United States. Because early prostate cancer is frequently without symptoms and data on how to prevent prostate cancer is lacking, early detection has the greatest potential for decreasing mortality. Studies have shown Hispanics/Latinos to be less likely than whites or African-Americans to utilize prostate cancer screening exams. The purpose of this descriptive study was to design a social marketing plan which could be used as a model to promote Hispanic/Latino participation at prostate cancer screenings. Information obtained through medical and marketing literature review, the author's experiences serving on the promotion committee of a community-sponsored prostate cancer screening project, and interviews with 51 Hispanic/Latino prostate cancer screening participants is described and incorporated into a guide with recommendations for future program planners.

The Psychological Effects of a Therapeutic Camping Experience on First Time Campers with Spina Bifida

Camping has been identified as a resource for educational, therapeutic, and recreational growth. The purpose of this study was to determine the psychosocial effects of a therapeutic camping experience with first time campers with spina bifida. In this study with four first time campers with spina bifida, three areas related to the camp experience were observed and measured: recreation participation, fun/pleasure, and self esteem. Both qualitative and quantitative methods were used, including the Coopersmith Self Esteem Inventory, the Recreation Participation and Fun Inventory, participant and non-participant observations, interviews, and a counselor questionnaire. The measurements of self esteem, recreation participation, and fun/pleasure were taken at three intervals, before camp, during camp and three weeks following the camp experience. The four camper case studies demonstrated that each camper experienced his/her own unique first time camp experiences.

Effects of Music on Vividness of Movement Imagery

The purpose of the investigation was to determine the effects of music on self reported vividness of movement imagery. Eighty-four undergraduate kinesiology majors (42 males; 42 females) were subjects. Based on identical perceptions of precategorized music (classical and jazz), selected subjects were randomly assigned to one of three music treatment conditions (sedative, stimulative, and control) and administered the Vividness of Movement Imagery Questionnaire. A 3 x 2 x 2 (Treatment x Gender x Perspective) ANOVA with repeated measures on the last factor was employed. The results revealed that the two music conditions significantly enhanced the vividness of internal and external imagery perspectives when compared to the no music condition, and that music facilitated the vividness of males and females equally.

The Significance of Time to Exhaustion at the Velocity at VO2Max

There were two primary goals in this investigation. The first goal was to determine if inter-individual variability in time to exhaustion at the velocity associated with V02max (Tlim at Vmax) was explained by anaerobic capacity (AC), Vmax, anaerobic threshold (AT), and/or a combination variable in the form [AC • (Vmax - vAT)^-1]. The second goal was to determine if AC could be predicted from Tlim at Vmax, AT, and/or a combination variable in the form [Tlim • (Vmax - vAT)].

Do American Adults Know How to Exercise for a Health Benefit? (open access)

Do American Adults Know How to Exercise for a Health Benefit?

Approximately 950,000 Americans die annually from cardiovascular disease. Physical activity is a major risk factor for the development of CVD and a risk factor for stroke. The purpose of this research was to determine whether American adults know how to exercise to achieve health benefits and whether this knowledge is a function of demographics. Items included knowledge of exercise guidelines and knowledge of traditional and non-traditional exercise activities. This information was obtained from 22 questions that were a part of a larger national survey of 2,002 American households. Statistical analyses of this sample, indicate American adults have knowledge which varies by demographic groups. Data revealed that overall the 61+, Less than High School, African-American, Hispanic-American, and Male groups have the least amount of knowledge about exercise. These data can provide health educators with important aspects of exercise knowledge for future health promotions/interventions.
