生物识别信息不同于个人信息、敏感个人信息,具有个体唯一性和不可变更性等特征。国际足球联合会已批准并推广使用可穿戴技术,通过可穿戴设备收集足球运动员生物识别信息以提升足球运动水平。从美国实践看,足球运动员生物识别信息的不当处理可能侵犯其隐私权、形象权和合同利益等。我国《个人信息保护法》已将生物识别信息纳入保护范畴。为此,急需厘清足球运动员生物识别信息的界限与例外情形,明确同意规则的范围与表达形式,细化足球运动员知情权、决定权、可携带权与删除权的实施规则,在行业规范中增加足球运动员生物识别信息的保护条款,并开展专项国际合作。 相似文献

很多年轻人都看到过他们的父母和朋友在一起的情景,并为这些老年人看上去是如此相像而感到震惊。他们饱经风霜的外貌,穿戴的衣服,偶尔有些僵硬的身体活动,以及讲述往事时所流溢出来的快乐,这一切是多么相像呀。事实上,大多数人都认为当人的年龄大了之后,就无一例外会呈现身体和心理全面衰老的状态,这也是各个国家的老人到了一定年龄就被要求退休的主要原因,几乎没有人考虑过很多六、七十岁,甚至八十岁的老人仍然像盛年时一样能干。对于人类来说,衰老虽然不可抗拒,但人和人并不完全相同,那种认为“所有的老年人都一样”的观点,其实是一个严重的误解。 相似文献

An international evidence-base demonstrates that healthy lifestyle digital technologies, like exergames, health-related mobile applications (‘apps’) and wearable health devices are being used more and more within educational settings. Despite this, there is a lack of in-depth empirical evidence on young people’s experiences and uses of healthy lifestyle technologies. In this article we focus on young people’s uses of a wearable health device – Fitbit – and the associated health app. Informed by the work of Foucault, the purpose is to investigate the surveillance, self-surveillance and resistance that occur by young people. One hundred 13–14 years olds (53 females, 47 males), from five physical education classes in two UK schools participated. Data were generated through 8 focus group interviews, and the nominal interview group technique was applied. Data were analyzed using key concepts from Foucault’s theoretical framework. The results demonstrated that, the daily 10,000 step and calorie burning targets set by the Fitbit device encouraged the young people to do more physical activity. Increases in physical activity occurred because of the self-surveillant practices promoted by the Fitbit through; (i) the monitoring and recording of steps and calories burned, and (ii) peer comparison (or monitoring). Surveillance and self-surveillance practices, however, were clearly connected to health equating to fitness and being ‘fit’ or not being ‘fat’. These narrow interpretations of health, equally, underpinned resistance. Daily step and calorie burning targets, (i) did not sustain young people’s engagement with the device beyond a few weeks, (ii) promoted negative feelings, and (iii) the device was resisted because it did not record physical activity accurately as part of young people’s daily lives. In turn, the young people resisted the educational value of the Fitbit and demonstrated a sceptical stance toward introducing health devices in school and physical education settings. 相似文献

The purpose of the current study was to define the impact of regular practice of Nordic walking on the gait of the elderly. Thereby, we aimed to determine whether the gait characteristics of active elderly persons practicing Nordic walking are more similar to healthy adults than that of the sedentary elderly. Comparison was made based on parameters computed from three inertial sensors during walking at a freely chosen velocity. Results showed differences in gait pattern in terms of the amplitude computed from acceleration and angular velocity at the lumbar region (root mean square), the distribution (Skewness) quantified from the vertical and Euclidean norm of the lumbar acceleration, the complexity (Sample Entropy) of the mediolateral component of lumbar angular velocity and the Euclidean norm of the shank acceleration and angular velocity, the regularity of the lower limbs, the spatiotemporal parameters and the variability (standard deviation) of stance and stride durations. These findings reveal that the pattern of active elderly differs significantly from sedentary elderly of the same age while similarity was observed between the active elderly and healthy adults. These results advance that regular physical activity such as Nordic walking may counteract the deterioration of gait quality that occurs with aging. 相似文献

This study examined ageing and free-living daily physical activity effects on salivary human beta-defensin 2 (hBD2). A total of 168 healthy elderly and 26 healthy young volunteers underwent saliva sampling. Free-living step count, energy expenditure and activity durations at specific intensity levels (inactive, light, moderate and vigorous) were evaluated. The results show significantly lower salivary hBD2 secretion rates for elderly than for young participants (P < 0.05). Data from elderly participants were stratified by steps per day using quartiles (Q1–Q4) for distribution. Elderly in quartiles respectively showed step counts of 3145 ± 129 in Q1, 5294 ± 83 in Q2, 7001 ± 86 in Q3 and 10,236 ± 416 steps · day?1 in Q4. In elderly participants, significant differences were found in the mean step count, energy expenditure and activity duration with increasing pedometer-determined activity quartiles. hBD2 secretion rates were significantly higher for Q2, Q3 and Q4 than for Q1 (P < 0.05). Elderly participants in Q3 had the highest hBD2 secretion. In conclusion, these results suggest that moderate physical activity in daily living improves age-related impairment of oral immune function mediated by hBD2. For oral immune function enhancement and for prevention of upper respiratory tract infections in elderly people, we recommend accumulation of more than 7000 steps · day?1. 相似文献

偏瘫步态中时相与周期的定量研究 总被引：5，自引：0，他引：5
目的:通过定量分析偏瘫患者的步行周期时相变化,发现其特征,从而为康复训练提供依据。方法:采用Wall和Ryuichi步态分析方法对30名偏瘫患者与30名正常对照受试者进行步行周期时相分析。结果:实验组中患肢比“健”肢的支撑期明显缩短,摆动期显著延长(P<0.01),对照组中两下肢的支撑期、摆动期无差异(P>0.05)。实验组与对照组的双支撑期、步行周期均存在显著差异(P<0.01)。结论:在自然行走过程中,偏瘫患者双下肢的单支撑期和摆动期的明显缩短是导致患者步行周期延长,步态异常,步速减慢,步行能力下降的根本原因。提示增加单足支撑训练是改善患者步态和步速的有效方法。 相似文献

Abstract Previously, gait had been considered an automatic and rhythmical movement that uses minimal attentional resources. The relationship between attention and gait has been revealed in recent research. However, in young adults in particular, the influence of using a cell phone – which is used frequently in daily life and considered to require high attentional demands – on gait has not been demonstrated. In this study, we examined the influence of mobile phone use on gait. Thirty healthy college students (15 males, 15 females) walked through a normal straight course with or without an obstacle under two different walking conditions while either using the email function of the cell phone or walking without a cell phone. The participants walked at a normal speed on a 10-m walkway. In walking conditions with an obstacle, an obstacle (17 cm in height) was set at the mid-point of the walkway. The following gait parameters were calculated: velocity, stride length, stride width (cm), and stance phase of one foot (just before an obstacle, one and two steps before the obstacle). Velocity and stride width decreased and the stance phase increased during walking while operating a cell phone. The stance phase just before an obstacle and stride length increased while operating a cell phone with an obstacle in the way. Gaze fixations and the high attention required to use the email function of the device may result in greatly disturbed gait. 相似文献
