Using self-determination theory as a framework, the purpose of this study was to test a structural model of hypothesized relationships among perceived need support from physical education teachers (autonomy support, competence support, and relatedness support), psychological need satisfaction (autonomy, competence, and relatedness), intrinsic motivation, and physical activity. Participants were 286 middle school students in the southeastern U.S. They completed previously validated questionnaires assessing their perceived need support from teachers, need satisfaction, intrinsic motivation, and physical activity. The hypothesized model demonstrated a good fit with the data (RMSEA = .08; CFI = .97; NFI = .96; GFI = .96). Need satisfaction and intrinsic motivation mediated the relationship between need support and physical activity. The constructs of perceived autonomy, competence, and relatedness represent the nutriments that facilitate students’ intrinsic motivation and ultimately positively predict students’ physical activity. The findings supported the theoretical tenets of self-determination theory.

The purpose of this study was to examine whether the relationships between contextual factors (i.e., autonomy-supportive vs. controlling coaching style) and person factors (i.e., autonomous vs. controlled motivation) outlined in self-determination theory (SDT) were related to prosocial and antisocial behaviors in sport. We also investigated moral disengagement as a mediator of these relationships. Athletes’ (n = 292, M = 19.53 years) responses largely supported our SDT-derived hypotheses. Results indicated that an autonomy-supportive coaching style was associated with prosocial behavior toward teammates; this relationship was mediated by autonomous motivation. Controlled motivation was associated with antisocial behavior toward teammates and antisocial behavior toward opponents, and these two relationships were mediated by moral disengagement. The results provide support for research investigating the effect of autonomy-supportive coaching interventions on athletes’ prosocial and antisocial behavior.

In this study, we examined whether perceived variety in exercise prospectively predicts unique variance in exercise behavior when examined alongside satisfaction of the three basic psychological needs (for competence, relatedness, and autonomy) embedded within self-determination theory (Ryan & Deci, 2002), through the mediating role of autonomous and controlled motivation. A convenience sample of community adults (N = 363) completed online questionnaires twice over a 6-week period. The results of structural equation modeling showed perceived variety and satisfaction of the needs for competence and relatedness to be unique indirect positive predictors of exercise behavior (through autonomous motivation) 6 weeks later. In addition, satisfaction of the need for autonomy was found to negatively predict controlled motivation. Perceived variety in exercise complemented satisfaction of the needs for competence, relatedness, and autonomy in predicting motivation and (indirectly) exercise behavior, and may act as a salient mechanism in the prediction of autonomous motivation and behavior in exercise settings.

Male coaches from NCAA Division I (n = 297), Division III (n = 294), and Japanese universities (n = 254) responded to the Coach Satisfaction Questionnaire measuring satisfaction with supervision, coaching job, autonomy, facilities, media and community support, pay, team performance, amount of work, colleagues, athletes’ academic performance, and job security; and Blau, Paul, and St. John's (1993) General Index of Work Commitment. Japanese coaches expressed significantly lower satisfaction than American coaches with seven facets (supervision, coaching job, autonomy, team performance, colleagues, athletes' academic performance, and job security). American coaches were significantly more committed to their occupation than the Japanese coaches who were significantly more committed to their organizations than American coaches.

Purpose:

To evaluate the effect of a solo ultraendurance open-water swim on autonomic and nonautonomic control of heart rate (HR).

Methods:

A male athlete (age 48 y, height 172 cm, body mass 68 kg, BMI 23 kg/m2) underwent HR-variability (HRV) and circulating catecholamine evaluations at different times before and after an ultraendurance swim crossing the Adriatic Sea from Italy to Albania. HRV was measured in 5-min segments and quantified by time and frequency domain. Circulating catecholamines were estimated by salivary alpha-amylase (sAA) assay.

Results:

The athlete completed 78.1 km in 23:44 h:min. After arrival, sAA levels had increased by 102.6%. Time- and frequency-domain HRV indexes decreased, as well (mean RR interval, −29,7%; standard deviation of normal mean RR interval, −63,1%; square root of mean squared successive differences between normal-to-normal RR intervals, −49.3%; total power, −74.3%; low frequency, −78.0%; high frequency, −76.4%), while HR increased by 41.8%. At 16-h recovery, sAA had returned to preevent values, while a stable tachycardia was accompanied by reduced HRV measures.

Conclusion:

To the authors’ knowledge, this is the first study reporting cardiac autonomic adjustments to an extreme and challenging ultraendurance open-water swim. The findings confirmed that the autonomic drives depend on exercise efforts. Since HRV changes did not mirror the catecholamine response 16 h postevent, the authors assume that the ultraendurance swim differently influenced cardiac function by both adaptive autonomic and nonautonomic patterns.

The study aim was to examine constructs of autonomy support and competence as well as the motivation continuum from the self-determination theory (SDT) as a framework for understanding physical activity (PA) motivation and behavior in breast cancer survivors. Questionnaires assessing demographics, medical factors, PA, motivation continuum, perceived autonomy support, and competence were completed by 558 breast cancer survivors. Results showed that lymphedema (X2 = 7.9, p < .01) and income (X2 = 4.6, p < .05) were associated with meeting PA guidelines. Moreover, survivors meeting PA guidelines reported more identified regulations and intrinsic motivation (p < .01), autonomy support (p < .01), and competence (p < .01). Forced entry hierarchical regression analysis showed that SDT constructs explained 20.2% (p < .01) of the PA variance. Significant independent SDT predictors included identified regulation (ß = .14, p < .05) and competence (ß = .23, p < .01), with autonomy support approaching significance (ß = .9, p = .057). SDT may be a useful model for understanding PA motivation and behavior in breast cancer survivors.

Based on self-determination theory, the purpose of this study was to explore the mediating role of autonomous motivation in the relation between environmental factors and pedometer-determined PA among 10- to 12-year-old Flemish children. Data were collected from 787 6th grade pupils and one of their parents. Children completed self-report measures including autonomous motivation for PA and perceived autonomy support for PA by parents and friends. Parents completed a questionnaire concerning their PA related parenting practices (logistic support and explicit modeling) and the perceived home environment with respect to PA opportunities. The results confirmed that autonomous motivation mediated the relation between children’s PA and their perceived autonomy support by friends and parents. Autonomous motivation also mediated the relation between parental logistic support and PA. In addition, a positive direct relation was found between parental explicit modeling and children’s PA, and between perceived neighborhood safety and children’s PA.

The purposes of this study were to, (a) assess motivational experiences of performance enhancement tasks (PET) and administrative tasks (AT), and; (b) examine the relationships of emergent motivational experiences of each task type to coaches’ perceived stress and intentions to continue coaching. In total, 572 coaches completed an online survey, which assessed autonomy, competence, relatedness, and other characteristics of PET and AT, intentions to continue coaching, and perceived stress. Two separate exploratory factor analyses (EFA) were conducted, one for AT and one for PET. This was followed up with confirmatory factor analysis (CFA) and SEM to examine relationships between emerging factors and stress and intentions. The factors generated for PET reflected ideas of autonomy, time conflict, and satisfaction, and for AT also included competence, effort, and job requirements. The resulting experiences of AT and PET appear to have different influences on stress and intentions, suggesting their distinction will be important in future work examining coach retention.

The purpose of this study was to examine the influence of an intervention grounded in Self-Determination Theory on preservice teachers’ instructional behaviors and the motivational responses of their students. A total of 62 preservice physical education teachers enrolled in a secondary physical education content and methods course were randomly assigned to either a treatment (n = 31) or a control group (n = 31). The study employed a pretest/posttest design and data were collected through: (a) observation of preservice teachers’ instruction, (b) a survey measuring preservice teachers’ perceptions of their autonomy support, and (c) a survey measuring secondary students’ motivation. Data analysis used repeated-measures ANOVAs to examine differences between the groups. Results indicated significant changes in autonomy-support for both teachers and students exposed to the intervention.

The purpose of this study was to examine the motivational effects of two different teaching styles in one sport activity. One class of 24 girls was taught track and field for 10 weeks, each lesson being taught with either a direct (practice) or a differentiated (inclusion) teaching style. After each lesson the girls completed self-report measures of intrinsic motivation and goal involvement. On course completion, 8 girls were interviewed to assess their reactions to the course. ANOVA showed that students reporting higher levels of competence, autonomy, and task orientation had higher intrinsic motivation scores throughout the course. However, teaching style was also found to have an independent effect; the differentiated style was associated with higher levels of intrinsic motivation and task goal involvement and lower levels of work avoidance involvement. A differentiated teaching style can positively influence young girls’ reactions to a sports activity independently of perceptions of goal orientations, autonomy, and competence.
