Although it is widely accepted that coping resources theoretically influence the stress-burnout relationship, it is unclear whether key internal (i.e., coping behaviors) and external (i.e., social support satisfaction) coping resources have stress-mediated or moderating influences on athlete burnout. Therefore we examined whether coping behaviors and social support satisfaction (a) had indirect stress-mediated relationships with burnout or (b) disjunctively (independently) or conjunctively (in combination) moderated the relationship between perceived stress and burnout. Senior level age-group swimmers (N = 244; ages 14–19 years) completed a questionnaire assessing burnout, perceived stress, general coping behaviors, and social support satisfaction. The results revealed that perceived stress, general coping behaviors, and social support satisfaction were related to burnout. Structural equation modeling demonstrated that general coping behaviors and social support satisfaction had stress-mediated relationships with overall burnout levels. Hierarchical multiple regression analyses failed to support the disjunctive and conjunctive moderation hypotheses. Results thus support stress-mediated perspectives forwarded in previous research.

Purpose:

The purpose of this study was to investigate the long-term effects of three types of training on well-being and frequency of physical activity and to determine whether preintervention motivation moderates the effects.

Methods:

Sixty-two older adults (M = 75 years old, SD = 5; 61% women) completed 4-mo programs of endurance, functional or strength training, with reassessment of well-being (life satisfaction, positive affect, negative affect, vitality) and physical activity 12 mo later.

Results:

All groups showed small improvements in most measures of well-being at 4 mo. At follow-up, endurance training still had small beneficial effects, while changes with functional and strength training were generally trivial or harmful. Analysis for moderators indicated that autonomously motivated individuals better maintained gains in well-being and had higher frequencies of physical activity at follow-up compared with controlled individuals.

Conclusion:

Endurance training is recommended for older adults, but the long-term outcomes depend on the individual’s motivational regulation at commencement.

Some attributes of neighborhood environments are associated with physical activity among older adults. This study examined whether the associations were moderated by driving status. Older adults from neighborhoods differing in walkability and income completed written surveys and wore accelerometers (N = 880, mean age = 75 years, 56% women). Neighborhood environments were measured by geographic information systems and validated questionnaires. Driving status was defined on the basis of a driver’s license, car ownership, and feeling comfortable to drive. Outcome variables included accelerometer-based physical activity and self-reported transport and leisure walking. Multilevel generalized linear regression was used. There was no significant Neighborhood Attribute × Driving Status interaction with objective physical activity or reported transport walking. For leisure walking, almost all environmental attributes were positive and significant among driving older adults but not among nondriving older adults (five significant interactions at p < .05). The findings suggest that driving status is likely to moderate the association between neighborhood environments and older adults’ leisure walking.

A recent study indicated that acute aerobic exercise improves cognitive flexibility in adults. The current study assessed age, habitual physical activity, and physical fitness as moderators of this improvement and examined whether the gains still exist an hour after the exercise session. The alternative-uses test, assessing cognitive flexibility, was administered individually to 20 older (age 63.67 ± 3.55 yr) and 19 young (age 23.9 ± 1.22) women before, immediately after, and an hour after a single moderate aerobic-exercise session. Results indicated significant improvement in cognitive flexibility in the older group immediately after the exercise but a decrease at the 1-hr follow-up. Further analysis indicated that physical fitness accounted for this improvement (R = –.622, p < .01). No such differences were observed in the young group. Further studies are needed to examine the duration of this effect, as well as the role of physical fitness as a moderator of it.

This research aimed to (a) determine whether mastery and intrateam performance achievement goals predicted prosocial and antisocial teammate behavior, (b) explore whether effects of intrateam performance goals were mediated by moral disengagement, and (c) examine whether any effects (Study 2 only) were moderated by cohesion. In Study 1, team athletes (N = 282) from Australia completed questionnaires assessing the aforementioned variables. Structural equation modeling indicated that prosocial teammate behavior was positively predicted by mastery-approach goals, and negatively predicted by mastery- and intrateam performance-avoidance goals, whereas antisocial teammate behavior was positively predicted by intrateam performance-approach and -avoidance goals; these latter effects were mediated by moral disengagement. In Study 2, team athletes (N = 452) from the United Kingdom completed a measure of cohesion in addition to the Study 1 instruments; the analyses largely confirmed the Study 1 findings. However, the undesirable effect of mastery-avoidance goals on prosocial behavior seen in Study 1 was only apparent in Study 2 when individuals held strong perceptions of team cohesion. In sum, this investigation makes a novel contribution to the literature on team functioning in sport, being the first to explore how athletes’ normative goals relative to their teammates might shape effective interaction processes.

Background:

Physical activity (PA) enjoyment may be an important determinant of long-term habitual, self-sustained PA behavior in children. The objective of the current study was to contribute toward a better understanding of how children’s PA enjoyment is associated with PA behavior by examining the influence of age, gender, BMI, and impulsivity as theoretically hypothesized moderators of this relationship.

Methods:

PA was measured in 171 children (77 boys, 91 girls) using accelerometers, and PA enjoyment was assessed with the validated Physical Activity Enjoyment Scale in 9-year-old children from the KOALA Birth Cohort Study, the Netherlands. Linear regressions were fitted. Moderation was tested by adding interaction terms between PA enjoyment and the potential moderators.

Results:

We found a significant 3-way interaction (PA enjoyment × gender × impulsivity) for all intensities of PA behavior. In boys, impulsivity strengthened the relationship between PA enjoyment and PA behavior, whereas in girls impulsivity weakened this relationship.

Conclusion:

In girls, this may be explained by the relative automatic occurrence of PA behavior in impulsive girls (independent of PA enjoyment). In boys, the possibility that impulsivity is associated with hyperactivity may explain this moderation. The current study may encourage researchers to investigate these interactions in future studies.
