The association between perceived injunctive norms toward corporal punishment,parenting support,and risk for child physical abuse     

《Child abuse & neglect》2019

The use of corporal punishment (CP) is a strong risk factor for many poor outcomes for children including child maltreatment. The use of CP occurs within social contexts which are important to understand. Although it is known that perceived social norms regarding CP are related to its use, the specific role that a mother’s primary support person plays in influencing attitudes toward and use of CP remains unknown. The current study assessed linkages between maternal perceived social support in parenting and perceived injunctive norms of CP from her primary source of support, with maternal attitudes toward and use of CP. Survey data were collected from female primary caregivers (N = 436) of children age 2 to 7 years (mean age = 3.7) enrolled in Special Supplemental Nutrition Program for Women, Infants and Children (WIC) clinics in Southeastern Louisiana. Most frequently, the biological father of the child (37.9%) and the maternal grandmother of the child (24.2%) were identified as the participant’s primary source of social support in parenting. Perceived injunctive norms of this support person toward CP use were significantly and positively associated with attitudes toward, AOR = 5.97, 95% CI = [4.04, 8.82], and use of CP, AOR = 3.77, 95% CI = [2.55, 5.59]. However, perceived social support was not associated with these outcomes and also did not moderate these associations. Findings suggest that efforts to reduce maternal risk for child physical abuse and use of CP must include the mother’s primary source of social support if they are to be successful.  相似文献

Acute fatigue negatively affects risk factors for injury in trained but not well-trained habitually shod runners when running barefoot     

Nicholas Tam  Devon R. Coetzee  Safwaan Ahmed  Robert P. Lamberts  Yumna Albertus-Kajee  Ross Tucker 《European Journal of Sport Science》2017,17(9):1220-1229

Introduction: Many factors may contribute to running-related injury. These include fatigue and footwear, the combination of which has rarely been studied, in particular with reference to barefoot running, recently advocated as a method to reduce injury risk. Methods: Twenty-two runners (12 well-trained and 10 trained) participated in a 10?km fatiguing trial. Knee and ankle joint kinematics and kinetics and electromyography were assessed during overground running in the barefoot and shod condition. This was performed pre- and post-fatigue using a motion capture system and force platforms. Results: Initial loading rate increased in the trained runners when barefoot but not shod. Shod knee stiffness increased in both groups after fatigue, whereas barefoot knee stiffness decreased only in the trained group. A reduction in barefoot bicep femoris pre-activation was found in both groups. During stance, a reduction in vastus lateralis and biceps femoris and an increase in tibialis anterior activity were found over time in both groups and conditions. Trained runners decreased gluteus medius and increased lateral gastrocnemius median frequency for both conditions after fatigue. Conclusion: When fatigued, gait adjustments in habitually shod runners may increase injury risk when running barefoot. Training status may be a risk factor for injury, as less-trained runners experience muscular fatigue changes that may compromise ground reaction force attenuation. Caution is recommended when transitioning to pure barefoot running.  相似文献   

Bicycle rider control skills: expertise and assessment     

Borut Fonda  Nejc Sarabon 《Journal of sports sciences》2017,35(14):1383-1391

Abstract

Research on how human balance and control bicycles are inconclusive, largely due to the small number of participants in the previous studies. Therefore, the aim of this study was to test the hypotheses that 1) cycling lateral deviation amplitude will reliably show differences between more and less experienced cyclists and 2) more experienced will exhibit slower and smaller steering motions compared to the less experienced cyclists. Twenty-eight experienced and inexperienced cyclists rode a bicycle in a straight line. Lateral deviation, steering and roll were measured. Intersession reliability of the deviation was high with Cronbach’s alpha values higher than 0.75. The amplitude, variability and rate of steering and roll parameters showed statistically significant differences between the groups. The test used in this study is sensitive to detect differences between more and less experienced cyclists and can be used for further research that aims to test the effect of a specific intervention addressing rider control. We also showed that steering and roll angle, which were described before as two of the main motor control actions in bicycle control, differ in the variability, amplitude and rate between more and less experienced cyclists. The results of the present study have practical implications for improving bicycle rider control and increasing the safety of cyclists.  相似文献
