Recent evidence indicates that low cardiorespiratory fitness (CRF) level, an independent risk factor for type 2 diabetes, is also more prevalent in African Americans than Caucasians. Numerous studies in Caucasian populations suggest that vigorous exercise intensity may promote greater improvements in CRF and other type 2 diabetes risk factors (e.g., reduction of glucose/insulin levels, pulse wave velocity, and body fat) than moderate intensity. However, current evidence comparing health benefits of different aerobic exercise intensities on type 2 diabetes risk factors in African Americans is negligible. This is clinically important as African Americans have a greater risk for type 2 diabetes and are less likely to meet public health recommendations for physical activity than Caucasians. The purpose of the HI-PACE (High-Intensity exercise to Promote Accelerated improvements in CardiorEspiratory fitness) study is to evaluate whether high-intensity aerobic exercise elicits greater improvements in CRF, insulin action, and arterial stiffness than moderate-intensity exercise in African Americans. Methods/Design: A randomized controlled trial will be performed on overweight and obese (body mass index of 25-45 kg/m 2) African Americans (35-65 years) (n = 60). Participants will be randomly assigned to moderate-intensity (MOD-INT) or high-intensity (HIGH-INT) aerobic exercise training or a non-exercise control group (CON) for 24 weeks. Supervised exercise will be performed at a heart rate associated with 45-55% and 70-80% of VO 2 max in the MOD-INT and HIGH-INT groups, respectively, for an exercise dose of 600 metabolic equivalents of task (MET)minutes per week (consistent with public health recommendations). The primary outcome is change in CRF. Secondary outcomes include change in insulin sensitivity (measured via an intravenous glucose tolerance test), skeletal muscle mitochondrial oxidative capacity (via near-infrared spectroscopy), skeletal muscle measurements (i.e., citrate synthase, COX IV, GLUT-4, CPT-1, and PGC1-α), arterial stiffness (via carotid-femoral pulse wave velocity), body fat, C-reactive protein, and psychological outcomes (quality of life/exercise enjoyment).

Athletes' perception of motivational climates and their own motives for sport participation influence enjoyment and long-term sport commitment. It is unknown, however, the extent parent motives for initially enrolling their child in a year-round sports program associate with children's sport participation enjoyment and commitment. The purposes of this study were to (a) determine parent motives for enrolling their child (5-8 years) in year-round swimming and (b) explore the relationships of parent motives and motivational climates with child enjoyment and commitment. Parents (n = 40) completed questionnaires on enrollment motives and motivational climate, while children (n = 40) answered questions on enjoyment and commitment. Of the seven motives measured, parents enrolled children in swimming primarily for fitness benefits (M = 4.5, SD = .45) followed by skill mastery (M = 4.31, SD = .48) and fun (M = 4.10, SD = .51) reasons. Findings revealed the fitness motive was moderately, negatively correlated with the success-without-effort facet of a performance climate (r = -.50, p < .01). The fun motive was moderately, positively associated with commitment (r = .43, p < .01). Parent motives for enrolling their child in sport may impact the young child sport experience and long-term sport continuation via motivational climates, enjoyment, and commitment.

Fue desarrollado por Raedeke y Smith (2001, 2009) para la evaluación de las tres subescalas que componen el síndrome: agotamiento físico/emocional, reducida sensación de logro y devaluación de la práctica deportiva. La finalidad de este estudio fue validar la versión española del Athlete Burnout Questionnaire (ABQ) en el contexto deportivo colombiano. Esta versión había mostrado buenas propiedades psicométricas en un estudio anterior (Arce, De Francisco, Andrade, Arce y Raedeke, 2010) por lo que se consideró adecuada para el presente trabajo. El instrumento se aplicó a 493 deportistas colombianos de ambos sexos con edades comprendidas entre los 13 y los 29 años, como en la adaptación española. Análisis confirmatorios sucesivos lograron replicar la versión española del ABQ. Los índices de ajuste global del modelo mostraron un buen ajuste: el valor del cociente entre el estadístico chi-cuadrado (176.46) y sus grados de libertad (85) fue de 2.07, GFI y CFI alcanzaron un valor de .95 y NNFI mostró un valor de .94. Los valores de RMSEA y SRMR fueron de .05. Además las cargas factoriales fueron todas significativas. Con respecto a la fiabilidad del cuestionario medida mediante el Alpha de Cronbach, mostró valores entre .55 y .75. De cara al futuro, sería de interés realizar un estudio comparativo entre las características psicométricas del cuestionario con datos recogidos en una muestra colombiana y en una muestra española.

In a preliminary work, the ABQ was translated into Spanish and administered to 140 male soccer players. In the present study, we include alternative statements for weaker items. A 21-item version was administered to a sample of 326 soccer players of both sexes aged 14-23 years old. Using item and factor analyses, the questionnaire was shortened to 15 items. Then, the data was submitted to confirmatory factor analysis to corroborate the usual three-factor structure. Overall fit of the model was acceptable with a value of .97 for CFI, .96 for NNFI, .93 for GFI, .059 RMSEA, and .061 for RMR.

Method: Fifty-six public university employees participated in a 10-week randomized controlled trial with 2 conditions that varied in theoretical fidelity. Participants in the high theoretical fidelity condition wore a pedometer and participated in a weekly group walk followed by a meeting to discuss cognitive-behavioral strategies targeting self-efficacy. Participants in the low theoretical fidelity condition met for a group walk and also used a pedometer as a motivational tool and to monitor steps. Step counts were assessed throughout the 10-week intervention and after a no-treatment follow-up (20 weeks and 30 weeks). Self-efficacy was measured preintervention and postintervention. Results: Participants in the high theoretical fidelity condition increased daily steps by 2,283 from preintervention to postintervention, whereas participants in the low fidelity condition demonstrated minimal change during the same time period (p = .002). Individuals attending at least 80% of the sessions in the high theoretical fidelity condition showed an increase of 3,217 daily steps (d = 1.03), whereas low attenders increased by 925 (d = 0.40). Attendance had minimal impact in the low theoretical fidelity condition. Follow-up data revealed that step counts were at least somewhat maintained. For self-efficacy, participants in the high, compared with those in the low, theoretical fidelity condition showed greater improvements. Conclusion: Findings highlight the importance of basing activity promotion efforts on theory. The high theoretical fidelity intervention that included cognitive-behavioral strategies targeting self-efficacy was more effective than the low theoretical fidelity intervention, especially for those with high attendance.

Design/Methods: Socially physique anxious female college age students participated in this study (N ¼ 99). A randomized 2 Â 2 factorial design was used to examine the effect of leadership style (health versus appearance oriented) and mirrors (present or absent) on affective responses, enjoyment, self-efficacy, and future intentions. Results: ANCOVA revealed that participants in the health oriented class reported more positive affective experiences than those in the appearance oriented classes with effect sizes (ES) ranging from .47 to .61. They also enjoyed exercise more (ES ¼ .40) and reported being more likely to join a similar class in the future (ES ¼ .69). Mirrors did not influence psychological responses by themselves or in conjunction with leadership style. Conclusions: Exercise leader behavior influences the quality of the exercise experience for individuals with social physique anxiety by creating a health or appearance oriented class atmosphere.

Cluster analysis revealed four groups:perfectionistic with maladaptive self-perceptions, perfectionistic (parent-driven) with maladaptive self-perceptions, achievement-oriented with adaptive self-perceptions, and nonperfectionistic with adaptive self-perceptions.Performers in both maladaptive clusters reported characteristics suggesting they were perfectionistic compared to their peers. They also reported relatively high contingent self-worth and low basic self-esteem. In contrast, those in thenonperfectionistic with adaptive self-perceptionscluster scored relatively low on perfectionism and reported relatively high basic self-esteem and low contingent self-worth. The performers in theachievement-oriented with adaptive self-perceptionscluster reported average scores across most variables, moderately high personal standards, and higher basic self-esteem compared with contingent self-worth. Overall, performers in both maladaptive clusters reported the highest burnout and lowest life satisfaction. Study findings underscore the importance of perfectionism and self-perceptions when considering burnout and life satisfaction.
