Effects of Yoga and Mindfulness Meditation on Stress-Related Variables: A Randomized Controlled Trial.

Stressful situations lead to change in or damage to the central nervous system, the hypothalamic-pituitary-adrenal axis, and autonomic function. Techniques for reducing stress such as yoga and mindfulness meditation have been reported to improve emotional regulation and mindfulness skill, as well as stress response. Mindfulness skill relies on intense focus to quiet the mind and bring concentration to the present moment.

The Specificities of Elite Female Athletes: A Multidisciplinary Approach.

Female athletes have garnered considerable attention in the last few years as more and more women participate in sports events. However, despite the well-known repercussions of female sex hormones, few studies have investigated the specificities of elite female athletes. In this review, we present the current but still limited data on how normal menstrual phases, altered menstrual phases, and hormonal contraception affect both physical and cognitive performances in these elite athletes.

Attitudes to functional neurology and some other 'prescriptive' chiropractic techniques and their associations with chiropractic conservatism: a cross-sectional survey of chiropractic students.

Background: Chiropractic technique systems ('prescriptive' techniques) might be interpreted as helpful guidelines. However, 'prescriptive' techniques, such as Functional Neurology (FN), Sacro-Occipital Technique, and Applied Kinesiology are more concerned with the 'technical' diagnosis than the condition and its symptoms and, thus, seem to provide easy solutions.

Design And Objectives: In a voluntary anonymous questionnaire survey carried out late 2017, we explored interest in 'prescriptive' techniques, particularly FN, among French chiropractic students in grades 3-6, and the possible link with chiropractic conservatism.

Effect of chiropractic treatment on primary or early secondary prevention: a systematic review with a pedagogic approach.

Introduction: The chiropractic vitalistic approach to the concept of 'subluxation' as a cause of disease lacks both biological plausibility and possibly proof of validity. Nonetheless, some chiropractors purport to prevent disease in general through the use of chiropractic care. Evidence of its effect is needed to be allowed to continue this practice.

Protective Role of Recent and Past Long-Term Physical Activity on Age-Related Cognitive Decline: The Moderating Effect of Sex.

This study aimed to investigate if the impact of both recent and long-term physical activity on age-related cognitive decline would be modified by sex. One-hundred thirty-five men (N = 67) and women (N = 68) aged 18 to 80 years completed the Modifiable Activity Questionnaire and the Historical Leisure Activity Questionnaire. A composite score of cognitive functions was computed from five experimental tasks.

Primary prevention in chiropractic practice: a systematic review.

Background: Chiropractors are primarily concerned with musculoskeletal disorders but have the responsibility to deal also with prevention in other areas.

Objectives: To establish the prevalence of chiropractors who have a positive opinion on the use of primary prevention (PP), their actual use of PP, and the proportion of patients who consult for PP in relation to (i) musculoskeletal disorders, (ii) public health issues, or (iii) chiropractic treatment for wellness.

Method: A systematic search for literature was done using PubMed, Embase, Index to Chiropractic Literature, and Google Scholar and updated on February 15th 2017.

Association between sports type and overuse injuries of extremities in adults: a systematic review.

Background: Sports injuries are often described as overuse or traumatic. Little is known about the frequency of overuse injuries and, in particular, if they vary between different types of sporting activities.

Purpose: To identify any differences between sports in relation to diagnoses of overuse injuries of the extremities (OIE) and anatomical areas most likely to be injured in adults and to compare these findings with those reported in youngsters, as identified in a previous review.

Leisure-time sport and overuse injuries of extremities in children age 6-13, a 2.5 years prospective cohort study: the CHAMPS-study DK.

Objectives: It is not known which sports are most likely to cause overuse injuries of the extremities in children. In this study, we report on the incidence of overuse injuries of the upper and lower extremities in children who participate in various leisure-time sports and relate this to the frequency of sport sessions.

Design: Natural experiment including a prospective cohort study.

A model-driven approach to studying dissociations between body size mental representations in anorexia nervosa.

This study compared dissociations between mental representations of current, ideal and normal body sizes (i.e., Current BS, Ideal BS and Normal BS) for women with anorexia nervosa (AN group, n=56) and healthy women (control group, n=56).

Association between sports type and overuse injuries of extremities in children and adolescents: a systematic review.

Background: Sporting activities can cause injuries and overuse injuries of the extremities (OIE) in children have been shown to be more common than injuries caused by trauma. The lower extremity is more frequently affected than the upper extremity in OIE, but it is not known whether injury site and diagnosis vary in different sporting activities.

Purpose: To identify any differences between sports in relation to diagnoses and anatomical areas most likely to be injured.

Is back pain during childhood or adolescence associated with muscle strength, muscle endurance or aerobic capacity: three systematic literature reviews with one meta-analysis.

Background: Back pain is a common condition during childhood and adolescence. The causes of back pain are largely unknown but it seems plausible that some physical factors such as back muscle strength, back muscle endurance and aerobic capacity may play a role in its development, in particular in the early years.

Objectives: The objectives of this review were to investigate in childhood and adolescence 1) if muscular strength in trunk extension is associated with back pain, 2) if muscular endurance in trunk extension is associated with back pain and 3) if aerobic capacity is associated with back pain.

Is puberty a risk factor for back pain in the young? a systematic critical literature review.

Background: Back pain is a common condition that starts early in life and seems to increase markedly during puberty. A systematic review was performed in order to investigate the link between puberty and back pain, using some Bradford Hill criteria for causality.

Objectives: We sought to obtain answers to the following questions: 1) Is there an association between puberty and back pain? If so, how strong is this association? And do the results remain unchanged also when controlling for age and sex? 2) Are the results of the studies consistent? 3) Is there a dose-response, showing a link between the increasing stages of puberty and the subsequent prevalence of back pain? 4) Is there a temporal link between puberty and back pain?

Design: A systematic critical literature review.

Dietary Intake, Eating Behaviors, and Diurnal Patterns of Salivary Cortisol and Alpha-Amylase Secretion Among Professional Young Adult Female Tennis Players.

Purpose: The aims of study were to examine the eating behaviors among 26 professional female tennis players and to assess the diurnal patterns of stress hormones through the measurement of awakening and diurnal profiles of salivary alpha-amylase (sAA) and cortisol concentrations.

Methods: Eating behaviors were assessed through three questionnaires (Eating Attitudes Test-26; Eating Disorders Inventory 2; and Body Shape Questionnaire), food intake by a 7-day diet record, and menstrual status by questionnaire. Perceived stress scale and anxiety state were also evaluated.

Global stress response during a social stress test: impact of alexithymia and its subfactors.

Objectives: Alexithymia is a personality trait characterized by difficulties in identifying, describing and communicating one's own emotions. Recent studies have associated specific effects of this trait and its subfactors with hypothalamo-pituitary-adrenal (HPA) axis markers during stress. The aim of this study was to analyze the association between alexithymia and its subfactors with HPA and sympatho-adrenal medullar (SAM) activity.

Attachment and alcohol use amongst athletes: the mediating role of conscientiousness and alexithymia.

Objective: The present study aims to explore the mediating effects of conscientiousness and alexithymia in the relationship between parental attachment style and alcohol use in a large sample of athletic young people.

Method: Participants included 434 French sport sciences students. Alcohol use, parental attachment style, conscientiousness and alexithymia were assessed.

Attentional patterns involved in coping strategies in a sport context.

We investigated the relationship between coping strategies and attentional bias after a sport competition. We administered the Ways of Coping Checklist (Paulhan, Nuissier, Quintard, Cousson, & Bourgeois, 1994) to 145 athletes immediately after they had participated in a sport competition. We also assessed attentional bias using a dot probe detection task.

Subjective age and social-cognitive determinants of physical activity in active older adults.

Objective: The purpose of the current study was to examine the mediating role of self-efficacy in the relationship between subjective age and intention to engage in physical activity (PA) among active older adults. It was expected that subjective age would be positively related to PA intention because it is positively associated with self-efficacy.

Method: A cross-sectional study was conducted with 170 older adults age 60-80 years (M = 66.

Where's the emotion? How sport psychology can inform research on emotion in human factors.

Objective: The aim of this study was to demonstrate how research on emotion in sport psychology might inform the field of human factors.

Background: Human factors historically has paid little attention to the role of emotion within the research on human-system relations. The theories, methods, and practices related to research on emotion within sport psychology might be informative for human factors because fundamentally, sport psychology and human factors are applied fields concerned with enhancing performance in complex, real-world domains.

Psychological mediators of the sport injury--perceived risk relationship.

Drawing upon both heuristic- and threat-based approaches, we sought to examine whether perceived similarity with injury-prone people and perceived control over injury occurrence would directly contribute to perceived risk and whether these variables would mediate the previous injury-perceived risk relationship. Judokas (n = 207) reported the number of injuries experienced in the past year and then completed measures of perceived similarity, perceived control, and injury risk perception. Analyses revealed that perceived similarity and perceived control directly contributed to perceived risk of injury; only perceived similarity acted as a partial mediator of the injury-perceived risk relationship.

Social cognitive determinants of physical activity among retired older individuals: an application of the health action process approach.

Objective: The identification of the determinants of physical activity (PA) among older adults is an important avenue of research. To date, although the health action process approach (HAPA) has proven to be a valid framework for the prediction of PA among heterogeneous sample of both middle-aged and older adults in rehabilitation and work settings, no studies have specifically considered its predictive value among older adults in their retirement years. Therefore, drawing upon the HAPA, the present study aimed to identify the social cognitive determinants of PA involvement among retired older adults.

Motivational predictors of coping with academic examination.

The present study focused on the motivational predictors of coping with academic examination through the test of the contribution of self-determination for academic studies and achievement goals. Coping strategies, academic motivation and achievement goals were assessed among 199 undergraduate students. Regression analysis revealed that problem-focused coping is positively predicted by identified regulation and negatively by amotivation, whereas emotion-focused coping is positively predicted by introjected regulation and amotivation.

Athletes' inclination to play through pain: a coping perspective.

Previous studies have shown how social networks lead athletes to accept pain as a "part of the game," which generates pressure on athletes to continue competing despite being in pain. Little is known, however, about the potential coping strategies that are related to pain behavior in sport. This study of 205 combat athletes examined whether pain coping strategies, including distraction from pain, praying, reinterpreting pain sensations, ignoring pain, and pain catastrophizing, are related to athletes' inclination to play through pain.

Who takes risks in high-risk sports? A typological personality approach.

We investigated the risk-taking behaviors of 302 men involved in high-risk sports (downhill skiing mountaineering rock climbing, paragliding, or skydiving). The sportsmen were classified using a typological approach to personality based on eight personality types, which were constructed from combinations of neuroticism, extraversion, and conscientiousness. Results showed that personality types with a configuration of low conscientiousness combined with high extraversion and/or high neuroticism (impulsive, hedonistic, insecure) were greater risk-takers.

Beyond sensation seeking: affect regulation as a framework for predicting risk-taking behaviors in high-risk sport.

Sensation seeking has been widely studied when investigating individual differences in the propensity for taking risks. However, risk taking can serve many different goals beyond the simple management of physiological arousal. The present study is an investigation of affect self-regulation as a predictor of risk-taking behaviors in high-risk sport.
