Controlled trial of a minimal-intervention exercise program for middle-aged working women

Abstract

Despite potential for major benefits, middle-aged women have low levels of aerobic exercise. A 12-week minimal-intervention exercise program was evaluated with female university employees aged 40 to 61. Following pre-testing, participants were randomly assigned to exercise or wait-list control. Testing was repeated at 12, 24 and 48 weeks. Exercisers improved significantly in aerobic fitness at 12 and 24 weeks, both groups decreased resting arterial pnssurc and body composition measures, and improved in exercise knowledge. Effects, however, were not well maintained at 48 weeks. These results are comparable to those obtained fmm intensive interventions and, while modest, suggest that a threshold has been reached for the modification of physiological control systems which are important for reducing cardiovascular disease risk. Middle-aged women face major social and practical baniers to regular exercise, and the minimal-intervention approach allows for a combination of flexibility and structure which seems appropriate for this group.     

Moderators of the relationship between exercise and mood changes: gender,exertion level,and workout duration

Although the role of exercise in improving mood is well established, less is known about moderators of this effect, particularly outside of the laboratory. The current study examined the effect of gender, type of exercise, level of exertion, and duration of workout on the exercise–mood relationship in a naturalistic setting. One hundred and thirty five participants (64 females) either engaged in weight training (n = 52) or cardiovascular (n = 83) exercise. Pre- and post-exercise assessments of mood were collected and changes in two types of mood, negative mood and exhaustion, were examined. Overall, participants reported improved mood after exercise in both domains. Workout duration and level of exertion significantly moderated the relationship of exercise to mood improvement (i.e., an increase in either corresponded to greater improved mood, ps<0.05). Overall, women showed more improved mood than men in the domain of exhaustion (p = 0.001).     

Concepts,mystics and post-Kantians

The presentist view of time is psychologically appealing. I argue that, ironically, contingent facts about the temporal properties of consciousness are very difficult to square with presentism unless some form of mind/body dualism is embraced.     

Testing Posttraumatic Stress as a Mediator of Childhood Trauma and Adult Intimate Partner Violence Victimization

This study examined whether potential posttraumatic stress disorder (PTSD) mediated the relationships between different forms of childhood trauma (sexual abuse, physical abuse, violence between caregivers) and intimate partner violence (IPV) victimization (psychological, physical, sexual). Participants were 1,150 female nurses and nursing personnel. Path analytic findings revealed potential PTSD partially mediated the relationships between childhood sexual abuse and psychological IPV and childhood sexual abuse and sexual IPV. Potential PTSD did not mediate the relationship between other types of childhood trauma and IPV. This study adds to the literature indicating PTSD as a risk factor for revictimization in the form of adult IPV among women. Screening for and treatment of PTSD among female child sexual abuse survivors could prevent future IPV victimization.     

Visual impressions of force exerted by one object on another when the objects do not come into contact

Simple animations in which one object contacts another give rise to visual impressions that the former object causes the outcome for the latter, and that the former object is exerting force on the latter. How does the impression of force relate to the impression of causality? The main aim of this research was to investigate this issue using stimuli in which there is a gap between the objects at closest approach. Delay between the first object stopping and the second object starting to move had a strong effect on reported force impressions, which is consistent with findings of research on the causal impression. However, the reported force impression was little affected by either the size of the gap or the presence and features of an object in the gap, whereas the causal impression was strongly affected by both. The findings support the conclusion that the force impression and the causal impression are distinct components of the visual interpretation of the stimulus.     

Play it again: neural responses to reunion with excluders predicted by attachment patterns

Reunion behavior following stressful separations from caregivers is often considered the single most sensitive clue to infant attachment patterns. Extending these ideas to middle childhood/early adolescence, we examined participants' neural responses to reunion with peers who had previously excluded them. We recorded event‐related potentials among nineteen 11‐ to 15‐year‐old youth previously classified on attachment interviews (11 secure and 8 insecure‐dismissing) while they played a virtual ball‐toss game (Cyberball) with peers that involved fair play, exclusion and reunion phases. Compared to secure participants, dismissing participants displayed a greater increment in the N2 during reunion relative to fair play, a neural marker commonly linked to expectancy violation. These data suggest a greater tendency toward continued expectations of rejection among dismissing children, even after cessation of social exclusion. In turn, the link between self‐reported ostracism distress and neural signs of negative expectancy at reunion was moderated by attachment, such that self‐reports were discordant with the neural index of expectancy violation for dismissing, but not for secure children.

Body checking and avoidance in ethnically diverse female college students

Although body checking and avoidance behaviors are common in women with eating disorders, minimal research has examined the nature or correlates of these behaviors in ethnically diverse female college students without eating disorders. Self-identified European American (n = 268), Asian American (n = 163), Latina (n = 146), and African American (n = 73) women completed self-report measures of body checking and avoidance, thin-ideal internalization, eating pathology, and clinical impairment. Results indicated that European and Asian American women reported significantly more body checking and avoidance than African American and Latina women. Generally, correlates of body checking and avoidance were consistent across ethnic groups: Regression analyses indicated that type of ethnicity predicted body checking and avoidance; and ethnicity, body checking, and body avoidance predicted eating pathology and clinical impairment. These associations suggest that body checking and avoidance are not benign behaviors in diverse nonclinical women.
