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.

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.

The Experiences of Young Adult-Aged Women from South Asian Countries Attempting to Participate in Sport and Physical Activity in the United States (open access)

The Experiences of Young Adult-Aged Women from South Asian Countries Attempting to Participate in Sport and Physical Activity in the United States

This study aimed to broaden the understanding of young South Asian women's experiences/relationships and participation in leisure physical activities at universities in the United States. Using a phenomenological design, semi-structured interviews of 20-30 minutes duration were conducted with 5 South Asian women about their relationships and experiences when participating or attempting to participate in physical activity while attending university in the US. The following criteria were set for participants to be included in this study: they should be between the ages of 18 and 24, non-US citizens from a South Asian country, attend a university in the US, and engage in other physical activities. The interviews were audio recorded via Zoom and then the audio data were transcribed verbatim and then coded to identify the major barriers commonly experienced by participants. Results indicated that many girls and women perceived the US as a "safer" place with excellent infrastructure, ample opportunities to engage in physical activities, and convenient access to gyms, which encourage them (women) to remain active. Most participants were hesitant to participate in physical activities because of the culturally non-responsiveness of the system. This research study was done in a shorter time span with a small sample size. Further …

Effects of Hypoxia Responses during Moderate- and Severe-Intensity Exercise Performed to Exhaustion

The purpose of the study was to investigate the effects of hypoxia responses during moderate- and severe-intensity exercise performed to exhaustion. Nine healthy university students, five men, and four women (mean ± SD, age, 23 ± 1 y; height 167 ± 8 cm; weight 73 ± 7 kg) performed a cycle ergometer test in normoxia and hypoxia conditions. Cardiorespiratory, metabolic, and perceptual responses were measured during moderate-intensity and during severe-intensity exercise. During moderate-intensity exercise, hypoxia exaggerates the cardiorespiratory and ventilatory responses and delays the attainment of the steady state VO2 kinetics. However, during severe-intensity exercise, compensatory responses were not adequate, oxygen demand was slightly increased and VO2 max was reduced in hypoxia affecting the overall performance. Therefore, the greater reliance on the anaerobic pathways could have a serious implication on the performance of the exercise over a wide range of intensities.

Relationship between Males' Coaching Efficacy and Prior Exposure to Sport Psychology (open access)

Relationship between Males' Coaching Efficacy and Prior Exposure to Sport Psychology

Coaching efficacy is largely influenced by mastery experiences such as formal education, coaching experience, and sport participation. Further examining specific experiences, such as exposure to sport psychology, may prove helpful in advancing our understanding of coaching efficacy. Thus, the purpose of this study was to explore male high school coaches' coaching experience to determine whether sport psychology education and interactions with sport psychology consultants relate to coaches' coaching efficacy. Participants, 585 males (Mage = 43.89 + 10.02), completed an online survey measuring coaching efficacy and coaching and sport psychology experience. A hierarchical regression analysis revealed that after controlling for years of coaching experience and school size, sport psychology education and interactions with sport psychology consultants were associated with higher overall coaching efficacy scores (p < .001). Additionally, analysis of covariance revealed that those with extensive sport psychology education had statistically higher coaching efficacy scores than those reporting no sport psychology education (p < .05). Knowledge of these phenomena may be relevant for sport psychology consultants, coach educators, and researchers.

Identity and Career Maturity in Kinesiology Students

The purpose of this study was to explore athletic identity, identity foreclosure, and career maturity in a sample of undergraduate college students currently enrolled in kinesiology and physical education classes at a university in the southern United States. Students were provided with an internet link that requested them to complete a demographic survey, the Athletic Identity Measurement Scale (AIMS), the foreclosure subscale of the Extended Objective Measure of Ego Identity Status, and the Attitude Scale (Form A-2) of the Career Maturity Inventory. Examination of the Pearson moment correlations indicated that the higher the sport participation during high school, the greater the athletic identity and identity foreclosure, and lower the career maturity attitudes. ANOVAs were performed to examine differences between males (n = 123) and females (n = 183), kinesiology (n = 181) and non-kinesiology majors (n = 125), and white (n = 144) and non-white students (n = 162) on athletic identity, identity foreclosure, and career maturity. Results showed that males scored significantly higher on athletic identity and identity foreclosure, and significantly lower on career maturity than females.

Predictors of Perfectionistic Tendencies in Sport among Undergraduate Kinesiology Students

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.

Resilience and Health Outcomes in Patients with Traumatic Injury (open access)

Resilience and Health Outcomes in Patients with Traumatic Injury

Due to the increasing healthcare costs and reduced length of hospital stay it is becoming increasingly important to identify individuals who are ‘at risk’ of experiencing long-term health issues. The purpose of the study was to: (1) determine if resilience, self efficacy and depression changed from inpatient to 3-month follow up; (2) examine the relationship between resilience, self efficacy, depression, and quality of life (social roles/activity limitations) at inpatient and 3-month follow up; and (3) identify if resilience at inpatient is related to change scores in selfefficacy and depression at 3-month follow up. Results from the paired sample t-test indicated that participants did not experience a significant change from inpatient to 3-month follow up in resilience or self-efficacy, but a significant decrease in depression was observed. Findings also indicated significant correlations between resilience, self-efficacy, and depression during inpatient stay and resilience, self-efficacy, depression, and quality of life at 3-month follow up. However, there was no relationship found between resilience and change scores in self-efficacy and depression. Future resilience research should continue to identify the variables that are most strongly related to resilience so effective interventions can be developed that improve rehabilitation outcomes, decrease secondary and chronic conditions as well as …

Limiting Disability Post-Brain Injury Through a Physical Activity Centered Education Program (open access)

Limiting Disability Post-Brain Injury Through a Physical Activity Centered Education Program

Brain injury (i.e., traumatic brain injury, stroke) is a considerable public health issue due to complicated outcomes of the injury, increasing incidence, and high costs linked with medical treatment. Rehabilitation centers are challenged to help individuals manage the resultant associated conditions and prevent secondary and chronic conditions. Research has shown that health promotion programs (HPP) that incorporate education about physical activity (PA) are one mode of rehabilitation that can improve the health of individuals with disabilities. However, PA is not included in the rehabilitation program for individuals with a brain injury, indicating a gap in the services provided. Consequently, the purpose of this study was to create and implement a physical activity centered education (PACE) program within an outpatient rehabilitation program. PACE consisted of an 8-week (16 session) program which aimed to (1) increase PA self-efficacy, (2) increase intention to change PA behaviors, (3) increase amount of PA completed regularly, and (4) promote positive rehabilitation outcomes. Based on previous research it was hypothesized that participation in PACE would result in (1) increased PA self-efficacy, (2) forward progression in intention to change PA behaviors, (3) increased amount of PA completed, and (4) improved rehabilitation outcomes (i.e., abilities, adjustment, participation).

The Influence of Psychological Momentum on Basketball Shooting Performance (open access)

The Influence of Psychological Momentum on Basketball Shooting Performance

The purpose of this research was to examine the influence of fictitious scoring updates on psychological momentum (PM) and athletic performance in a competitive basketball setting. The participants included in this study were 50 male undergraduate students who reported having played basketball previously and qualified by being able to make more than 24% (12 out of 50) of their 3-point shots in a pre-trial session. Participants were told that they were competing in a 50 shot, 3-point shooting competition against another individual, equal in ability. After every 10 shots, participants were given a fabricated score update and answered four questions used to measure PM. Results showed that the fictitious score updates significantly (p < .01) influenced participants’ PM scores, where those who were told they led had higher PM scores than those who were told they trailed. As for shooting performance, no significant differences (p = .76) were found between positive and negative PM states for participants who reported experiencing both during the competition. Together, these findings suggest that manufactured score updates can influence PM, but resultant performance differences may not exist. Results of this study lend support to the notion that PM is experienced by athletes. However, when examining …

The Effects of a Psychosocial Environment on College Women’s Exercise Regulations and Social Physique Anxiety

A positive psychosocial intervention comprised of high autonomy support, task-involvement, and caring was implemented in physical activity classes to examine its effects on college women’s basic psychological needs (i.e. autonomy, competence, relatedness), exercise regulations (i.e. external, introjected, identified, integrated, intrinsic) and social physique anxiety (SPA). We hypothesized that at the end of the semester, participants in the intervention group (N = 73) would report greater need satisfaction, more self-determined regulations and less SPA than participants in the non-intervention group (N = 60). At T1 and T2, both the intervention and non-intervention participants reported “agreeing” with experiencing an autonomy supportive, task-involving, and caring environment. Furthermore, both groups at T1 and T2 reported moderate SPA. No significant group differences were found at T1. At T2, significant group differences were observed in the intervention and non-intervention groups’ report of external regulation and intrinsic regulation. The results suggests that group exercise instructors are capable of creating a positive psychosocial environment to enhance students’ intrinsic motivation.

Reliability and Validity of the FITNESSGRAM® Physical Activity Items

Large-scale assessments of children and youth physical activity (PA) behaviors are regularly conducted in school settings. In addition to assessing actual fitness, the FITNESSGRAM® assesses self-reported PA behaviors for aerobic, strengthening, and flexibility activity within the past 7 days. The purpose of this study was to examine the reliability and validity of the three PA items. Participants included 1010 students in grades three through twelve and were either tested under a teacher – teacher condition, an expert - expert condition, a teacher – expert condition, or a trained teacher – expert condition. Comparisons of the responses to the PA items indicated adequate reliability for teachers, but the reliability improved with training. Likewise, the validities for teachers are moderate to fair; however, they improved when teachers received additional training.

Identifying the Physical Activity Needs of Outpatients with a Traumatic Brain Injury (open access)

Identifying the Physical Activity Needs of Outpatients with a Traumatic Brain Injury

Traumatic brain injury (TBI) is a significant public health issue due to the incidence, complexity, and cost associated with treatment – emphasizing the need for effective rehabilitation programs. One mode of rehabilitation that has been demonstrated to improve health and reduce healthcare costs is health promotion programs (HPPs) that incorporate physical activity (PA). However, PA is not currently incorporated into the standard of care post-TBI. The purpose of this study was to conduct group interviews among individuals with a TBI undergoing outpatient rehabilitation to determine PA knowledge, attitudes, intentions, and barriers. Results will be used to develop a HPP that focuses on facilitating PA participation as part of the rehabilitation process. Seventeen participants completed a series of group interviews (2-3 people/group) regarding their PA needs. A qualitative research design was adopted and trustworthiness was established through triangulation of data (i.e., theoretical underpinning; multiple researchers and data-coders). A cross-case analysis was completed to identify themes and conceptual patterns. The main themes identified were (1) an inability to differentiate between PA and physical therapy, (2) a limited knowledge of PA health benefits and the relationship to rehabilitation, and (3) an interest in participating in a PA HPP as part of their rehabilitation. …

Relation Between the FITNESSGRAM® Ftness Assessment and Self-Reported Physical Activity Questions

The FITNESSGRAM® is regularly used to assess physical fitness (PF) of adolescents. In addition to the PF assessment, the FITNESSGRAM also includes self-report physical activity (PA) items. The purpose of this study was to examine whether the self-report aerobic, muscular strengthening, and flexibility PA behavior items indicated adolescents’ cardiorespiratory, muscular strength, and flexibility fitness and their body composition. Logistic regression analysis was used to examine the relation between the amount of PA and PF status. Adolescents not meeting the recommended PA amount had significantly higher odds of not achieving a healthy fitness status. Meeting the recommended PA amount was associated with achieving healthy PF status. Thus, adolescents’ amounts of aerobic, muscular strengthening, and flexibility PA were an indication of their corresponding health-related PF standard.

Reliability of an On-line System to Assess Physical Activity Behaviors in an Active Group of Kinesiology Undergraduate Students

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 …

Effect of Resistance Training on Cytokines in Hiv+ Men with Chemical Dependence

Human immunodeficiency virus (HIV) and substance abuse (drug and/or alcohol) independently impair the immune system; importantly, the combination of HIV infection and substance abuse might produce more than an additive effect on this system. Tumor necrosis factor-alpha (TNF-?) and Interferon gamma (IFN?) are pro-inflammatory cytokines involved in differentiation of Th0 cells into Th1 cells. Interleukin 4 (IL-4) and Interleukin 10 (IL-10) are anti-inflammatory cytokine involved in differentiation of Th0 cells to Th2 cells. Unbalanced Th1 and Th2 cells can lead to immune suppression. Thus, changes in these cytokines could have important implications for people infected with HIV (HIV+). Resistance training can counteract muscle wasting, improve strength, and improve muscle mass. The purpose of this study was to examine the effect of resistance training on resting concentrations of circulating TNF-?, IFN-?, IL-4, and IL-10. Sixteen men (42 ± 11 years, 180.4 ± 9.1 cm, 89.2 ± 20.7 kg) infected with HIV and enrolled in an intensive 60-day in-patient substance addiction/abuse treatment program were recruited shortly after admission to the treatment facility.

Soul Line Dancing Among African American Women in the Church: an Expectancy-value Model Approach

Guided by the expectancy value model of achievement choice, this study examined the relationships among expectancy value constructs (expectancy related beliefs and subjective task values), effort and intention for future participation in a culturally specific dance, soul line, among African American adult women in the church setting. Participants were 100 African American women who were members of the women’s ministries from four predominantly African American churches in the Dallas/Ft. Worth metropolitan area. Participants completed a 20-minute soul line session and responded to survey questions, validated in previous research, assessing their expectancy-related beliefs, subjective task values, effort, intention for future participation and physical activity. This was the first study to use the expectancy value model as a guide to determine motivations attached to physical activities among African American adult women. Usefulness, a component of subjective task values, emerged as a predictor of intention for future participation. Eighty-one percent of the women did not meet physical activity guidelines for aerobic activity. Of those inactive women 60% indicated an interest in doing soul line dancing often at their church after one short exposure to the activity as indicated by the strongest possible response to both intention questions.

Mechanisms Affecting Bench Press Throw Performance while Using a Counter-Balanced Smith Machine (open access)

Mechanisms Affecting Bench Press Throw Performance while Using a Counter-Balanced Smith Machine

The use of a counter-balance weight system of a Smith machine affects measures of bench press throw performance. Twenty-four men performed bench press throws at 30% of their one-repetition maximum under four different conditions: 1) counter-balance and rebound movement (RC), 2) no counter-balance and rebound movement (RNC), 3) counter-balance and concentric only movement (CC), and 4) no counter-balance and concentric only movement (CNC). Peak power, force, and concentric and eccentric velocities were measured using a linear accelerometer; and peak ground reaction force (GRF) was measured using a forceplate. Peak measures for concentric and eccentric velocities showed that NCB> CB and RBT > CBT. Peak GRF measures showed CB > NCB and RBT > CBT. The lower performance measures for CB were likely due to an increase in the net external load when the barbell accelerates faster than the gravitational constant causing the counter-balance weight becomes ineffective.
