The purpose of this study was to examine current kinesiology students' athletic identity, identity foreclosure, perceived task value in sport, and perfectionism. An online survey was distributed via email to current kinesiology students. The survey contained questions regarding demographic information and items from the Athletic Identity Measurement Scale, Extended Objective Measure of Ego Identity Status, Perceived Task Value in Sport, Sport Multidimensional Perfectionism Scale-2, and Multidimensional Inventory of Perfectionism in Sport. Results of the Pearson moment correlations indicated that the higher the athletic identity, the higher the subjective task value, identity foreclosure, perfectionistic strivings, and perfectionistic concerns. Multiple regression analyses were performed to further examine the predictive power of athletic identity, subjective task value, and identity foreclosure for perfectionistic strivings and perfectionistic concerns. Results indicated that athletic identity and subjective task value were significant predictors of perfectionistic strivings. Results also showed that athletic identity and identity foreclosure were significant predictors of perfectionistic concerns. Future research should replicate the study using participants from different geographical regions. Furthermore, future research should consider a longitudinal and qualitative study to investigate the development of subjective task value in sport.

The purpose of this study was to investigate endocrine responses to redistribution with heavier loads (RR+L) during back squat (BS) exercise in resistance-trained men. Ten men (mean±SE; 23±2 years, 175.6±2.0 cm, 78.0±3.4 kg, 4±1 training years) were assigned using randomization to either RR+L (4 sets of (2×5 repetitions) of BS with 30 s intra-set and 90 s inter-set rest using 75% of their 1RM) or traditional sets (TS; 4 sets of 10 repetitions of BS with 120 s inter-set rest using 70% of their 1RM). Fasted blood samples were collected pre-exercise (PRE), immediately post-exercise (IP), and 5 (+5), 15 (+15), and 30 (+30) minutes post-exercise to analyze the concentrations of testosterone (T), growth hormone (GH), cortisol (C), and blood lactate (BL). Two-way ANOVAs with repeated measures were used (p≤0.05). A main effect of condition (p=0.023) was observed for BL (RR+L; 5.9±0.5 vs TS; 6.7±0.4 mmol/L). A main effect of time point (p≤0.001) was observed for T, GH, C, and BL. T was greater at IP (8.8±1.1), +5 (9.0±1.1), +15 (8.5±1.0), and +30 (8.0±1.0) than PRE (7.1±0.8 ng/mL). GH was greater at IP (58.3±12.7), +5 (62.8±12.7), +15 (67.9±13.3), and +30 (52.8±11.2) than PRE (3.6±1.6 µIU/mL). C was greater at +15 (25.5±2.9) …

Acute sleep loss may lead to elevated fatigue, decreased energy, and diminished cognitive performance. Traditionally, sleep extension is used to restore mood and cognitive function to baseline levels following insufficient sleep, yet this method may not be feasible or preferred. Acute exercise may serve as an affordable and relatively safe intervention to reduce detriments to daytime functioning following sleep loss. The primary purpose of this study was to examine the effects of moderate-intensity aerobic exercise on neurocognitive function following acute sleep restriction. A secondary aim was to examine the effects of exercise in subjective reports of fatigue, energy, and sleepiness following acute sleep restriction. Fifty-six participants, matched by sex, age, and chronotype, were randomly assigned to either an exercise (EX) or seated control (SC) condition. Following a 4-hour sleep restriction protocol, participants completed the oddball paradigm before and after 20 minutes of exercise or stationary sitting. P3 amplitude and latency, arousal, sleepiness, energy, and fatigue were assessed during the experiment. After controlling for pre-test differences, P3 latency was significantly faster following exercise relative to the control group. No significant P3 amplitude differences were observed between conditions. The EX group displayed significant improvements in arousal, sleepiness, energy, and fatigue compared to …

Acute aerobic exercise exerts a small beneficial effect on cognition. Much of the research to date has focused on cognitive changes following a bout of exercise, while little is currently known about changes in cognitive performance during exercise. The limited research that has been conducted suggests either positive, negative, or no effects on cognitive performance during exercise. Thus, the primary purpose of this study was to examine the effects of low-intensity cycling on cognitive function in college-aged students, indexed by response accuracy, reaction time, P3 amplitude, and P3 latency. Twenty-seven (Mage = 22.9 ± 3.0 years old) college-aged individuals were counterbalanced into low-intensity exercise (EX) and seated control (SC) conditions. During each condition, participants completed a 10-minute resting baseline period, 20 minutes of either sustained cycling or seated rest, and a 20-minute recovery period. Primary outcomes were assessed at 10-minute intervals (5 blocks total) throughout each condition via a modified oddball task. Across time blocks, both conditions exhibited faster reaction times on frequent trials but reduced accuracy to rare trials, suggesting a speed-accuracy tradeoff. There were no differences between conditions in P3 latency whereas a significant reduction in P3 amplitude was observed during the 20-minute exercise period compared to the …

Music is used to distract, energize, and entertain during exercise by producing positive psychological and physiological responses. Specifically, listening to music during exercise enhances performance, increases motivation, improves affect, and optimizes arousal. Researchers have identified several elements of music that may moderate this relationship, including lyrics. However, few studies to date have examined the influence of motivational lyrics on psychological and physiological states during exercise. Thus, the primary purpose was to investigate the effects of lyrics in music on motivation, affect, arousal, and perceived exertion during moderate intensity cycling. Thirty (Mage = 21.0 ± 2.9 years old) college-aged individuals performed three, 8-min acute bouts of moderate-intensity exercise on a cycle ergometer during music with lyrics (ML), music without lyrics (MNL), and no music control (MC) conditions. Measures of motivation, affect, arousal, and perceived exertion were taken before and after a 6-min warm-up, every 2-min during the exercise bout, and following a 2-min cool-down. For ML and MNL conditions, participants reported higher motivation, affect, and arousal during exercise relative to the MC condition. As expected, RPE increased throughout the exercise period, with no condition differences observed. Additionally, there were no differences in responses between the ML and MNL conditions. Collectively, these …

The purpose of this study was to examine the relationship between adolescents' perceptions of their parents' encouragement to lose weight and physical activity habits (i.e., exercise habits and sedentary behaviors) and their own physical health-related fitness (HRF) and psychological well-being. Results of structural equation modeling revealed both similarities and differences between boys and girls. Specifically, parental sedentary behavior and encouragement to lose weight related to girls HRF. Among boys, only encouragement to lose weight related to HRF. When inspecting the relationship between HRF and psychological well-being, HRF related to body satisfaction, but not depressive symptoms, among both boys and girls. Results of this study highlight the complex influence that parental perceptions have during adolescent development.

Introduction/purpose: Recovery from muscle damage involves a type of programmed cell death known as apoptosis. Damage Associated Molecular Patterns (DAMPs) are released after muscle damage and may cause premature apoptosis in monocytes infiltrating the damaged site. This may alter the time course of events towards recovery. Therefore, the purpose of this study was to investigate if downhill running causes a change in the susceptibility of monocytes to apoptosis. Methods: Participants (5 male, 6 female) completed a downhill running protocol consisting of 6-5 minute bouts at a speed of 6-9mph on a -15% grade treadmill. Venous blood samples were collected immediately pre-exercise (PRE), in addition to 4 -h, 24 -h and 48 -h post-exercise. Creatine kinase (CK) was measured to give an indication of muscle damage. Monocytes were analyzed by flow cytometry for expression of multicaspase and annexin v reagent was used to detect changes in the plasma membrane. A MILLIPLEX MAP human early apoptosis magnetic bead 7-plex kit (EMD Millipore, Billerica, MA) was used to assess the relative concentration of phosphorylated protein kinase B (Akt), Bcl-2 associated death promoter (BAD), B cell lymphoma-2 (Bcl-2), active caspase-8, active caspase-9, c jun N terminal kinase (JNK) and tumor protein p53 by Luminex …

This study investigated the relationship between belief in coaching abilities (coaching efficacy beliefs, CEB), transformational leadership behaviors (TLB), and motivational climate development of current strength and conditioning coaches working with high school level athletes. The measures used were the coaching efficacy scale for high school teams (CES II-HST, Myers et al.,2000), the differentiated transformational leadership inventory (DTLI, Callow et al., 2009), and the patterns of adaptive learning scales (PALS, Midgley et al., 2000). It was hypothesized that CEB and TLB would influence motivational climate development, while coaches' background characteristics would correlate with CEB, TLB, and motivational climate development. The 60 coaches who participated reported an average of thirteen (SD=8) years of experience and 51 were Certified Strength and Conditioning Specialists. Coaches reported high efficacy, frequent use of TLB, and development of a moderately high task- and somewhat ego-involving motivational climate. Correlations between demographic variables and CEB, TLB, and motivational climate development revealed three significant relationships: years of experience with CEB, and professional development activities and athlete to coach ratio with ego-involving climate development. CEB and TLB had a strong positive correlation. Two regression analyses were conducted to determine if the outcomes of the CEB and TLB measures predicted motivational climate …

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.

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.

This thesis focused on the development of a curriculum guide for a cancer awareness program for older men. The background of the problem -- a lack of programs for older men -- and the methods used in developing the guide are detailed in Chapter One. The second chapter consists of current information on disease prevention, aging and cancer with the emphasis on age-related changes and learning needs of older adult men. Chapter Three is the completed instructor's curriculum guide, and the final chapter includes recommendations on implementing the program as part of a community wellness program. The guide could also be used in senior centers, hospital educational programs, or adapted for use in staff inservices.

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.

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.

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.

A random sample of 365 students attending a university in northern Texas returned a mailed questionnaire measuring the students' knowledge of Acquired Immuno-Deficiency Syndrome (AIDS), their perceived susceptibility to AIDS, and their sexual practices during the last year. The students had high knowledge levels about AIDS in general. However, 70% did not worry about getting AIDS. Collectively, there was a display of concern until it became a personal issue. The students (59%) saw themselves as less likely than most people to get AIDS. Although 70% of this sexually active group did not use condoms, they still did not perceive themselves as susceptible to AIDS.

The purpose of this study was to investigate two different plyometric training techniques for increasing vertical jumping ability. Twenty-four female high school volleyball players were matched for height and weight and distributed equally among three groups. Each subject performed a vertical jump test, Margaria power test, Wingate bicycle test, and an isokinetic leg strength test prior to and following six weeks of training. Plyometric training significantly (p<.05) improved vertical jumping ability and some indices of leg strength and power. Weighted plyometrics did not enhance performance more than plyometrics alone. These data support the view that plyometric training with or without added weights enhances vertical jumping and leg power.

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.

Although the “self” has generally been conceptualized as relatively stable in sport-specific research, events such as deselection, injury, and career termination have been found to negatively affect athletes’ levels of identification with the athlete role. Additionally, there has been limited research regarding competitive failure and its ability to negatively affect athletes’ levels of identification with the athlete role. The purpose of the present investigation was to provide additional evidence regarding the influence poor competitive seasons have on the malleability of athletes’ self-identity. Athletes were followed throughout the course of their season to determine whether athletes who encountered a poor competitive season reported lowered levels of athletic identity. Specifically, male and female NCAA Division I track and field athletes completed pre-indoor, post-indoor, and post-outdoor assessments of athletic identity. Contrary to previous research, the current study’s results indicated no identifiable relationship between male and female athletes’ season performance satisfaction and their level of post-indoor and post-outdoor athletic identity. Thus, the greatest predictor of athletes’ post-season level of athletic identity was their pre-season level of athletic identity, regardless of season performance. Given these results, future research should assess self-esteem as well as other potential coping strategies athletes might use in order to gain …

Engaging in muscle strengthening activities (MSA) as part of a physical activity program offers health benefits. Although the merits of physical activity are well documented, many adults fail to meet appropriate levels as recommended in the 2008 Physical Activity Guidelines for Americans (PAGA). To get a more complete understanding on an individual's physical activity behaviors, the Tracking Resistance Exercise and Strength Training (TREST) internet based survey was developed. The purpose of the current study was to determine the test-retest reliability of TREST items. Additionally, the prevalence of participants meeting the 2008 PAGA was reported by gender. The survey was completed approximately two weeks apart by 224 (52% male) undergraduate kinesiology students. Analysis of the survey items presented TREST as a reliable instrument in assessing an individual's physical activity behavior with a focus on MSA. Among the convenience sample of 445 participants (56% male) that completed the survey in assessment #1, 73% met the 2008 PAGA minimum recommendations for MSA (>=2 days/week) and aerobic activity (>= 150 min MVPA). A more complete MSA and MVPA criteria was established (requiring MSA of all seven major muscle groups) and only 32% of participants met this guideline. In general, men engaged in aerobic exercise …

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.

The purpose of this study was twofold: 1) To analyze the similarities and differences between parent responses to the birth and rearing of a child with Down syndrome and; 2) To document the characteristics of grieving described in Engel's 3-stage model of grieving. A questionnaire was used to assess responses from randomly chosen parent members of the Dallas Down Syndrome Guild. Qualitative data analysis was conducted, using the methodology of triangulation.

Six male long-distance runners participated in this study to evaluate the responses to exercise at 90% and 100% vV02max. Subjects participated in five maximal exercise tests: one incremental, three tests at 90% vV02max, and one test at 100% vV02max. The results of this study demonstrate that V02max can be elicited in a constant-velocity test at 90% vV02max.

The purpose of this study was to compare the torque generating capabilities and fatigue responses of female power athletes, female endurance athletes, and age-matched female non-athletic controls.

This study examines the relationship between exercise adherence and several factors: self-motivation; attitudinal commitment; predisposing, enabling, and reinforcing (PER) factors; and barriers related to exercise. The sample (N=431) consists of employees at Texas Instruments, Incorporated in Dallas, Texas. The sample was placed into six comparison groups: high adherers, low adherers, nonparticipants who exercise, nonparticipants who do not exercise, dropouts who exercise and dropouts who do not exercise. Using a one-way ANOVA, the results show significance (p<.01) among the groups for: self-motivation and barriers. Attitudinal commitment and PER factors did not show significance. The results can be applied to worksite health programs to increase exercise adherence among employee populations.
