Description
In the past decade, research has demonstrated the relationship between higher levels of self-compassion and lower levels of negative psychological outcomes. More recently, the concept of self-compassion has been explored within the context of various health behaviors. Very few studies have investigated the potential relationship between self-compassion and eating behaviors. Based on literature and the established relationship between negative self-evaluation and abnormal eating behaviors/eating disorders, the current study sought to examine correlations between self-compassion, eating behaviors, and stress in first time college freshmen. The study population consisted of 1478 participants; ages 18-22 years; females = 936 (63%), males = 541 (37%). Participants self-reported measures of the Perceived Stress Scale (PSS), the Three Factor Eating Questionnaire (TFEQ), and the Self Compassion Scale (SCS). PSS score, the overall score and individual subscale scores of SCS, and the three subscale scores of the TFEQ (restraint, disinhibiton, hunger) were examined with Pearson correlations. Results of this study indicate significant (p = < .05) differences between males and females in PSS and all three negative SCS subscales. There was a strong and consistent correlation between the eating behavior of disinhibition and all three negative constructs of self-compassion (self-judgment, r = .29; isolation, r = .23; over-identification, r = .28) in females. The eating behavior of restraint was similarly correlated with SCS self-judgment in females (r = .26). More research is needed to understand differences in stress, self-compassion, and eating behaviors between males and females and to better comprehend the weak associations between eating behaviors and the positive psychological constructs of self-compassion (self-kindness, common humanity, and mindfulness) for males and females. Additionally, future research should focus on the three subscales of disinhibition as they relate to the negative constructs of self-compassion. The preliminary results of this study suggest it would be beneficial, particularly to female college freshmen, to more fully understand the dynamics of the relationship between eating behaviors and self-compassion; this knowledge may help to better structure appropriate coping strategies for the prevention of disordered eating behaviors.

Description
Physical inactivity is a continuing public health crisis because of its negative effects on health (e.g. hypertension, cardiovascular disease, type II diabetes). To combat the rising prevalence of these non-communicable diseases, physical activity (PA) promotion is a public health priority. However, current programs seem to be ineffective in the long-term promotion of PA. Resultingly new, effective interventions are needed. Recent studies have established a link between mindfulness and PA engagement. Based on the current literature, the present study sought to investigate the associations between trait mindfulness, behavioral regulation towards exercise, exercise intention, stress, and self-reported PA. This study also examined whether trait mindfulness was independently associated with meeting weekly, leisure-time, moderate-to-vigorous PA [MVPA] recommendations in university undergraduate students after controlling for demographic characteristics, past PA experience, exercise intention, stress, and motivation.
The study used a cross-sectional design and participants consisted of 180 undergraduate university students (aged 18 to 24 years). Participants completed a one-time survey that assessed demographic characteristics, trait mindfulness, behavioral regulation toward exercise, exercise intention, perceived stress and PA. Bivariate associations between the variables were assessed with Pearson or Spearman correlations. A logistic regression analysis was conducted to determine which variables were independently associated with meeting weekly, leisure-time MVPA guidelines. Results of this study found weak positive associations between the mindfulness domain of acceptance and leisure time MVPA ( = .168, p < .05), no associations between mindfulness and transportation PA, and negative associations between mindfulness (MAAS, = –.238, p < .01; acceptance, = –.175, p < .05) and sitting time. Results of logistic regression found that only relative autonomy (OR = 1.085, 95% CI [1.008, 1.168], p = .030) and intention (OR = 2.193, 95% CI [1.533, 3.138], p < .0001) were independently associated with meeting weekly, leisure- time MVPA recommendations. The results of this study show that while there is only a weak direct relationship between trait mindfulness and PA, mindfulness may be related with other factors associated with PA. More research is needed in order to better understand the potential mechanisms behind the results found in this, and past, studies.

Description
This study examines cognitive and motor function in typical older adults following acute exercise. Ten older adults (Mage = 65.1) completed a single session of assisted cycling (AC) (i.e., exercise accomplished through the use of a motor), voluntary cycling (VC) (self-selected cadence), and a no cycling (NC) control group. These sessions were randomized and separated by approximately one week. Both ACT and VC groups rode a stationary bicycle for 30-minutes each session. These sessions were separated by at least two days. Participants completed cognitive testing that assessed information processing and set shifting and motor testing including gross and fine motor performance at the beginning and at the end of each session. Consistent with our hypothesis concerning manual dexterity, the results showed that manual dexterity improved following the ACT session more than the VC or NC sessions. Improvements in set shifting were also found for the ACT session but not for the VC or NC sessions. The results are interpreted with respect to improvements in neurological function in older adults following acute cycling exercise. These improvements are balance, manual dexterity, and set shifting which have a positive effects on activities of daily living; such as, decrease risk of falls, improve movements like eating and handwriting, and increase ability to multitask.

Description
Background and purpose: Regular physical activity (PA) provides benefits for cognitive health and helps to improve or maintain quality of life among older adults. Objective PA measures have been increasingly used to overcome limitations of self-report measures. The purpose of this study was to investigate the association of objectively measured PA and sedentary time with cognitive function among older adults.
Methods: Participants were recruited from the parent REasons for Geographic and Racial Differences in Stroke (REGARDS) Study. ActicalTM accelerometers provided estimates of PA variables, including moderate-to-vigorous PA (MVPA), high light PA (HLPA), low light PA (LLPA) and sedentary time, for 4-7 consecutive days. Prevalence and incidence of cognitive impairment were defined by the Six-Item Screener. Letter fluency, animal fluency, word list learning and Montreal Cognitive Assessment (orientation and recall) were conducted to assess executive function and memory.
Results: Of the 7,339 participants who provided accelerometer wear data > 4 days (70.1 ± 8.6 yr, 54.2% women, 31.7% African American), 320 participants exhibited impaired cognition. In cross-sectional analysis, participants in the highest MVPA% quartile had 39% lower odds of cognitive impairment than those in the lowest quartile (OR: 0.61, 95% C.I.: 0.39-0.95) after full adjustment. Further analysis shows most quartiles of MVPA% and HLPA% were significantly associated with executive function and memory (P<0.01). During 2.7 ± 0.5 years of follow-up, 3,385 participants were included in the longitudinal analysis, with 157 incident cases of cognitive impairment. After adjustments, participants in the highest MVPA% quartile had 51% lower hazards of cognitive impairment (HR: 0.49, 95% C.I.: 0.28-0.86). Additionally, MVPA% was inversely associated with change in memory z-scores (P<0.01), while the highest quartile of HLPA% was inversely associated with change in executive function and memory z-scores (P<0.01).
Conclusion: Higher levels of objectively measured MVPA% were independently associated with lower prevalence and incidence of cognitive impairment, and better memory and executive function in older adults. Higher levels of HLPA% were also independently associated with better memory and executive function. The amount of MVPA associated with lower risk of cognitive impairment (259 min/week) is >70% higher than the minimal amount of MVPA recommended by PA guidelines.

Description
Purpose: This study explored the potential correlates of exercise self-efficacy among older adults with a self-reported diagnosis of arthritis. Methods: This study was a secondary data analysis and used a cross-sectional design. Data was collected from a convenience sample of Non-Hispanic White and Non-Hispanic Black individuals between 2006-2008 (N=208). Descriptive statistics were run to assess means and frequencies within the sample. Bivariate statistics (Pearson and Spearman correlations, T-tests and one-way analysis of variance) were run to examine relationships between the independent and dependent variables. Multiple linear regression analyses were conducted to examine independent predictors of self-efficacy for exercise (SEE) and barriers self-efficacy for exercise (BSE). Results: Participants were predominantly female (85.6%), white (62.9%), retired (58.1%) and had a mean age of 66.6 [10.7] years. For education level, 23.4% reported a Master’s degree or higher and 18.6% reported they had at most a high school degree or GED. Nearly 47% of the sample were classified as obese based on self-reported body mass index (BMI) and 68.3% of the sample were not meeting the American College of Sports Medicine physical activity (PA) recommendations. Participants reported a relatively high BSE (22.6) and an average SEE (22.7). Significant positive associations were seen with outcome expectation for exercise (EOE), social support, and total minutes of PA and negative associations with BMI, physical function, pain, and negative affect with SEE and BSE. Meeting the PA guidelines (t134.5=4.60, 95%CI= 4.7(6.71-2.68), p<0.001) and being white (t164=2.82, 95%CI=2.82(0.57-5.08), p=0.014) were associated with SEE and BSE (t165=3.42, 95%CI= 4.37(6.89-1.85), p=0.001) and (t164=2.34, 95%CI= 2.95(0.46-5.43), p=0.021), respectively. In regression analyses, significant predictors of SEE were education (p=.006), physical function (p=.006) and EOE (p<.001). Significant predictors of BSE were physical function (p=.020), social support (p=.031), EOE (p=<.001), education level (p=.037), and total minutes of PA (p=.022). The variables in the SEE model accounted for 50.5% (R=.737, R2=.505) of the total variance and the variables in BSE model accounted for 41.1% (R=.672, R2=.411) of the total variance of the model. Discussion: EOE appears to be an important predictor of SEE and BSE. Examining the temporal relationship between EOE and SEE is warranted.

ABSTRACT
The purpose of this study was two-fold. In Specific Aim One, we examined the associations between education level, personal trainer credentials and characteristics, and knowledge of exercise science and personal training principles. In Specific Aim Two we examined associations between education, personal trainer credentials and knowledge of personal trainers with client retention. This study utilized a cross-sectional research design. An anonymous electronic survey was used to collect the data. Eligible participants (N=226) were individuals who were providing one-on-one personal training services for at least one client. All data were assessed for normality prior to data analysis. Descriptive statistics were used to evaluate sample characteristics. Mean and standard deviations, median and interquartile range [IQR] or frequency and percentages were reported for the sample characteristics. Bivariate associations were examined with dependent t-tests and one-way ANOVAs for normally distributed data. Mann- Whitney U and Kruskal-Wallis tests were used for non-normally distributed variables. The median knowledge score for the sample was 6.0 [3.00] points, out of a possible 24, with 92.5% of the sample scoring 10 or lower. Sex (Male/Female), education level, having a degree in the field, certification status (yes
o) and number of certifications were not associated with knowledge scores (p > 0.05). Years of experience in personal training was positively associated with mean knowledge scores (H(3) = 9.280, p = 0.026). Sex of the personal trainer, having a degree in the field (yes
o), the number of personal trainer certifications, the cost of training, the type of facility, the type of employment of the personal trainer and knowledge scores were not associated with client retention (p > 0.05). Education level (F3,87 = 8.176, p < 0.001), personal training certification (yes
o) (t38 = 2.277, p = 0.029), years of experience (F3, 87 = 3.169, p = 0.028), facility size (F4,84 = 8.049, p < 0.001), and exercise science degree type (F3,48 = 6.008, p = 0.001) were all associated with client retention. This study provides insight on knowledge retention of active personal trainers on subject matter deemed foundational by four certifying organizations. The findings should influence both the preparatory learning and well as continuing education approaches of both certifying organizations and institutions of higher learning.
