随着5G信息化时代的到来,现代化篮球也逐渐向着智能化、数据化、科学化的方向发展,人工智能在篮球领域的推广和应用是提高篮球训练水平,进而缩小与篮球强国之间差距的重要手段。传感器件是人工智能设备的核心器件,与硬性传感器相比,柔性传感器具有良好的柔韧性、延展性与较高的探测灵敏度,能够紧密贴合在运动员的身体部位甚至是人体关节等不规则表面,因此近年来受到了广泛关注与蓬勃发展。本文中,将重点阐述不同类型的柔性可穿戴传感器应用于篮球技术训练方面的具体要求以及相关研究进展,具体为:柔性可穿戴应变传感器应用于人体大应变技术动作监测,柔性触觉传感器及手指弯曲传感器应用于投篮手型指导与纠正,以及柔性足底压力传感器应用于足底压力监测和伤病预防。 相似文献

A functional food product for the management of weight 总被引:1,自引:0,他引:1
More than half of Americans have a body mass index of 25 kg/m2 or more, which classifies them as overweight or obese. Overweight or obesity is strongly associated with comorbidities such as type 2 diabetes mellitus, hypertension, heart disease, gall bladder disease, and sleep apnea. Clearly, this is a national health concern, and although about 30 to 40% of the obese claim that they are trying to lose weight or maintain weight after weight loss, current therapies appear to have little effect. None of the current popular diets are working, and there is room for innovation. With the advancing science of nutrition, several nutrients - low-glycemic-index carbohydrates, 5-hydroxytryptophan, green tea extract, and chromium - have been identified that may promote weight loss. The first two nutrients decrease appetite, green tea increases the 24-h energy expenditure, and chromium promotes the composition of the weight lost to be fat rather than lean tissue. These have been assembled in efficacious doses into a new functional food product and described in this review. The product is undergoing clinical testing; each component has already been shown to promote weight loss in clinical trials. 相似文献

ABSTRACT: Potato tubers are a staple food item in the North American diet. Each potato cultivar has unique tuber appearance and nutritional composition. A method was developed to facilitate better cultivar selection for dietary purposes and obtain a better understanding of the nutrient distribution within specific tissues of potato tubers. This involved a procedure for estimating the percent weight contribution of the 3 major tissue components, including periderm or "skin," cortex, and pith for 20 potato cultivars. Weight determination was based on the volume (calculated through an ellipsoid formula) and density of each component tissue. Calculated percent weight and dry matter data for each tuber tissue provided conversion factor values that were tabulated for all cultivars. An example is provided to illustrate the application of this procedure in facilitating identification of cultivars with significantly greater or lesser protein content. 相似文献

A transducer to directly measure lethality rates during thermal processing was designed and tested. The transducer consisted of a double-legged thermocouple, thermocouple conditioner, and an antilog amplifier. Lethality rates measured real-time during thermal process experiments compared well with those calculated after-wards. A microcomputer data acquisition system was designed to evaluate this transducer. This data system was a general purpose system and can be easily modified to meet the data recording needs of similar experiments and routine processing operations. 相似文献
