How about running on Mars? Influence of sensorimotor coherence on running and spatial perception in simulated reduced gravity.

Motor control, including locomotion, strongly depends on the gravitational field. Recent developments such as lower-body positive pressure treadmills (LBPPT) have enabled studies on Earth about the effects of reduced body weight (BW) on walking and running, up to 60% BW. The present experiment was set up to further investigate adaptations to a more naturalistic simulated hypogravity, mimicking a Martian environment with additional visual information during running sessions on LBPPT.

Neuromuscular adjustments to unweighted running: the increase in hamstring activity is sensitive to trait anxiety.

Originally developed for astronauts, lower body positive pressure treadmills (LBPPTs) are increasingly being used in sports and clinical settings because they allow for unweighted running. However, the neuromuscular adjustments to unweighted running remain understudied. They would be limited for certain lower limb muscles and interindividually variable.

Epidemiology of sport climbing injuries caused by a climbing fall among climbers of the French Federation of Mountain and Climbing.

Background: Fall-related injuries (FRIs) are the most severe sport climbing injuries. The main objective of this study was to measure FRI prevalence and risk factors in a representative sample of climbers of the French Federation of Mountain and Climbing. The second objective was to explore FRI mechanisms.

Sex and Age Differences in the Endorsement of Sex Stereotypes Associated with Driving.

Sex and age differences are particularly pronounced in car accidents. Current psychological research is exploring the relationship between risky driving and compliance with sex stereotypes, notably conformity with social expectations concerning masculinity. Some studies have already shown that sex stereotypes associated with driving (SSAD) may influence driving behaviors.

Pilot evaluation of physical and psychological effects of a physical trek programme including a dog sledding expedition in children and teenagers with cancer.

Aim Of The Study: To evaluate the feasibility and to measure the effects of a six-week-long adapted physical activity programme (APAP), including 5 days of intense dog sledding, on the physical and psychological health of children and adolescents treated for cancer.

Methods: Eleven children and teenagers (4 girls, 7 boys; mean age 14.3 ± 2.

Are drivers' comparative risk judgments about speeding realistic?

Introduction: This study focused on comparative judgments about speeding risks among young drivers who have a high risk of being involved in a traffic accident.

Method: We examined (a) how these drivers assess their risk of sanctions and their risk of causing an automobile crash because of speeding in comparison to the estimated risks of other drivers, and (b) how realistic their comparative risk judgments are. We measured the relationship between the drivers' comparative risk judgments, self-reported speeding, and driving-related sensation-seeking.

Risk taking and risk perception in road safety: comparative study of young sportsmen and nonsportsmen in southeastern France.

The relationship between participation in sporting activity and both risk taking and risk perception when traveling on a two-wheeled vehicle were evaluated among 614 adolescents between the ages of 14 and 17 years. The sex of the respondents (252 girls, 362 boys) and their experience with road accidents were taken into account. Three-way analyses of variance indicated a significant main effect for sex, with girls reporting both fewer risky behaviors and higher risk perception than boys when traveling on a two-wheeled vehicle.

Brief report: how do adolescents perceive the risks related to cell-phone use?

Besides the social risks of incivility and impoliteness (I-incivility), cell-phone use is classically associated with two types of physical risk: microwave radiation (LIMRadiation) and decreased attention while driving (CPUWDriving). As the literature has showed that adolescents' risky behavior was consistent with their risk perception, we ran a self-report survey to evaluate 1/how French adolescents (n=1129) perceived physical risks related to CPUWDriving, exposure to LIMRadiation, and social risks related to I-incivility; and 2/the factors underlying these risk perceptions. Results showed that adolescents have an acute perception of the risks associated with CPUWDriving and appeared to be concerned, as a whole, with social risks related to I-Incivility.
