This study analyzed the biomechanical and physiological effects of the arm swing in roller ski skating, and compared leg-skating (i.e. ski skating without poles) using a pronounced arm swing (SWING) with leg-skating using locked arms (LOCKED). Sixteen elite male cross-country skiers performed submaximal stages at 10, 15 and 20 km h−1 on a 2% inclined treadmill in the two techniques. SWING demonstrated higher peak push-off forces and a higher force impulse at all speeds, but a longer cycle length only at the highest speed (all P < .05), indicating a lower force effectiveness with SWING at the two lowest speeds. Additionally, the flexion–extension movement in the lower limbs was more pronounced for SWING. Oxygen uptake was higher for SWING at the two lowest speeds (both P < .05) without any differences in blood lactate. At the highest speed, oxygen uptake did not differ between SWING and LOCKED, but the RER, blood lactate and ventilation were lower with SWING (all P < .05). Taken together, these results demonstrate that utilizing the arm swing in roller ski skating increases the ski forces and aerobic energy cost at low and moderate speeds, whereas the greater forces at high speed lead to a longer cycle length and smaller anaerobic contribution. 相似文献

The current study examined drink driving attitudes among mature-aged women in Sweden and Australia, two countries with a Blood Alcohol Concentration (BAC) limit of 0.02% and 0.05%, respectively. The study aimed to identify attitudes that might influence drink driving tendency among this group of women and further show how these attitudes vary across countries. Using an ethnographic approach, 15 mature-aged women (Sweden: mean age = 52.5 years, SD = 4.8; Australia: mean age 52.2 years, SD = 3.4) were interviewed in each country. General patterns and themes from the data were developed using thematic analysis methods. The findings indicate that while women in both countries viewed drink driving negatively, the understanding of what the concept entailed differed between the two samples. The Swedish women appeared to cognitively separate alcohol consumption and driving, and consequently, drink driving was often spoken of as driving after any alcohol consumption. The Australian women’s understanding of drink driving was more closely related to the legal BAC limit. However, for some Australian women, a “Grey Zone” existed, which denoted driving with a BAC of just above the enforceable limit. While illegal, these instances were subjectively seen as similar to driving with a BAC of just under the legal limit and therefore not morally reprehensible. The practice of cognitively separating drinking from driving appeared to have implications for the tendency to drink and drive among the interviewed women. These findings are discussed in relation to current policy and legislation in Australia and the need for further research into mature-aged women’s drink driving is outlined. 相似文献

Self-report measures of driving-related attitudes and beliefs miss potentially important precursors of driving behaviour, namely, automatic and implicit thought processes. The present study used an adapted Go/No-go Association Task to measure implicit thought without relying on the participants’ self-reports. Implicit attitudes towards safe and risky driving were measured in 53 Danish drivers (31 female, 22 male). Further, we explored the relationship between implicit attitudes towards risky and safe driving, and self-reported driving behaviour and skills. The results suggest that implicit attitudes towards driving behaviour can be measured reliably with the Go/No-go Association Task. Also, the results suggest that implicit attitudes towards safe driving and risky driving, respectively, may be separable constructs, and might thus stem from different cognitive processes. Finally, implicit attitudes were significantly related to self-reported driving behaviour and skills for male (but not female) drivers. Pending future research with larger sample sizes, the difference between implicit attitudes towards safe versus risky driving that we observed may contribute to a greater theoretical understanding of the causes of safe and risky driving. 相似文献

The automobile is currently the most popular and frequently reported location for listening to music. Yet, not much is known about the effects of music on driving performance, and only a handful of studies report that music-evoked arousal generated by loudness decreases automotive performance. Nevertheless, music tempo increases driving risks by competing for attentional space; the greater number of temporal events which must be processed, and the frequency of temporal changes which require larger memory storage, distract operations and optimal driving capacities. The current study explored the effects of music tempo on PC-controlled simulated driving. It was hypothesized that simulated driving while listening to fast-paced music would increase heart rate (HR), decrease simulated lap time, and increase virtual traffic violations. The study found that music tempo consistently affected both simulated driving speed and perceived speed estimates: as the tempo of background music increased, so too did simulated driving speed and speed estimate. Further, the tempo of background music consistently affected the frequency of virtual traffic violations: disregarded red traffic-lights (RLs), lane crossings (LNs), and collisions (ACs) were most frequent with fast-paced music. The number of music-related automobile accidents and fatalities is not a known statistic. Police investigators, drivers, and traffic researchers themselves are not mindful of the risks associated with listening to music while driving. Implications of the study point to a need for drivers' education courses to raise public awareness about the effects of music during driving. 相似文献

Senior drivers are vulnerable to automobile crashes and subsequent injury and death. Safety belts reduce health risks associated with auto crashes. Therefore, it is important to encourage senior drivers to wear safety belts while driving. Using a repeated baseline design (AAB), we previously reported that motivating signs boosted safety belt usage by drivers exiting senior communities from baseline (72% and 68% usage), to postinstallation of signs (94%), to 6 months follow-up (80%). The current study was a 4-year follow-up in which six senior communities, with seat belt signs, were compared to six matched control senior communities with no signs. Safety belt usage was stable, across 4 years, at approximately 80% for both male and female drivers and front seat passengers for the six communities with signs, and was approximately 55% for control sites. These finding suggest that the simple and low-cost intervention of erecting signs to prompt safety belt use has persistent benefits that affect driver and passenger behavior alike. 相似文献

In order to better understand parental influence on teen driving, a series of three studies were conducted among parents of young drivers to examine the association between their scores on the Family Climate for Road Safety Scale (FCRSS; Taubman – Ben-Ari & Katz – Ben-Ami, 2013) and three relevant factors: parental self-efficacy (Study 1, n = 101); parents’ attitudes toward accompanied driving (Study 2, n = 100); and teen’s driving styles (Study 3, n = 235 parents–young drivers pairs). The findings of Study 1 revealed significant associations between parents’ scores on the positive FCRSS dimensions and their self-reported parental competence. In addition, parents’ lack of commitment to safe driving was related to lower parental self-efficacy. Study 2 indicated significant associations between parents’ scores on the positive FCRSS dimensions and the positive attitude of relatedness during the accompanied driving phase. Negative associations were found between these FCRSS dimensions and negative perceptions of the accompanied driving phase (i.e., tension, disapproval, and avoidance). The findings of Study 3 showed significant associations between parents’ scores on the positive FCRSS dimensions and their offspring’s careful driving style, as well as negative associations between these dimensions and offspring’s endorsement of the reckless, angry, and anxious driving styles. Taken together, the results indicate the importance of the family climate as part of a global understanding of the dynamic surrounding youngsters’ driving. Furthermore, they show that the particular driving-related family climate is associated not only with parents’ self-perceptions and conduct in the early stages of their children’s driving (the accompanied driving phase of a GDL), but also impacts the way teenagers ultimately choose to drive, when they are on their own. Implications for interventions are discussed. 相似文献

Relations between results of the Stress Strategy Test (SST), a computerized test the first author developed partly involving the Stroop effect, and of an interview and an intelligence test used by the Swedish armed forces as selection instruments for placement of recruits in type of military service were investigated in a group of 3,205 recruits. The SST results were found able to explain 17.64% and 12.25% of the variance in results of the intelligence test and the interview, respectively. Emotional stability and psychological energy were the two interview variables most closely related to results of the SST. The usefulness of the SST in a selection context is discussed. 相似文献

Reckless driving is a key factor in injury and death among young people, especially men, throughout the world. At this developmental stage (ages 17–24), the youngster’s behavior, including driving habits, is strongly influenced by the social discourse. Whereas previous studies have investigated the impact of concepts such as peer pressure and the number of passengers in the car, they have dealt little with the overall social relations that characterize young people, particularly, the nature of their friendships and their reflection in safe versus risky driving.Using qualitative phenomenological methodology, the present study relies on 32 semi-structured in-depth interviews to explore the elements of the relationships among young drivers in the context of driving behavior. Aristotle’s conceptualization of three types of friendship was employed as the interpretative framework. The findings reveal that a young driver’s behavior when driving with friends is associated with the different perceptions of friendship, and is gender and age sensitive. The elements of a friendship of utility (reciprocal interests, practical and beneficial interactions) were connected with safety at all ages and in both genders, and those of a friendship of virtue (responsibility, equality, concern for others) were associated with safe driving among females of all ages and among some of the older male drivers (21–24 years). In contrast, the components of a friendship of pleasure (spending leisure time together, sharing mutual interests) were related to risky and distracted driving, especially among the younger male drivers (17–19 years). It is suggested that interventions might promote safe driving among young people by fostering the positive aspects of their peer relationships. 相似文献
