An Investigation of Value-, Impression-, and Outcome-Relevant Involvement on Attitudes,Purchase Intentions,and Information Seeking

This investigation explored the relationship between value-relevant (VRI), impression-relevant (IRI), and outcome-relevant involvement (ORI) on information-seeking behaviors, attitudes, and purchase intentions. Results revealed that grocery shoppers' (N = 175) ORI was positively associated with information-seeking behaviors, attitudes, and purchase intentions of foods high in fiber. Neither VRI nor IRI predicted attitudes or purchase intentions. Results are discussed with an emphasis on information seeking among the three types of involvement and message-design strategies with respect to promoting foods high in fiber.

体育教育专业学生营养与能量消耗状况调查与分析

本文对苏州大学体育学院体育教育专业学生进行膳食与24h能量消耗调查。结果表明：膳食结构不合理，动物性食物摄入过多。蛋白总量和动物蛋白偏多，豆类蛋白摄入不足，脂肪尤动物脂肪摄入量超标，Vc、VB2和钙缺乏，并存在脂肪供热比偏高，碳水化合物供热比偏低及早餐摄入能量低的问题。能量消耗显示，女生摄入能量超出消耗量，男生能量基本平衡。建议调整膳食结构，使各营养素的供应均衡。     

结直肠癌营养风险筛查研究进展

营养风险是指现存的或潜在的与营养因素相关的导致患者出现不良临床结局的风险。结直肠癌是常见的恶性肿瘤,在我国发病率逐年升高,由于生理病理原因,以及治疗方法使其更易存在营养风险。现将营养风险及其筛查常用工具进行简单综述,并重点综述结直肠癌营养风险筛查2002（NRS 2002）的应用现状,以期指导临床实践。     

Science and medicine of rowing: A review

The biology and medicine of rowing are briefly reviewed. Effort in a 2000 -m race is about 70% aerobic. Because the boat (and in some instances a cox) must be propelled, successful competitors are very tall, with a large lean mass and aerobic power. Large hearts may lead to erroneous diagnoses of a cardiomyopathy. Large respiratory minute volumes must be developed by chest muscles that are also involved in rowing. The vital capacity is typically large, and breathing becomes entrained. Expiration cannot be slowed relative to inspiration (as normally occurs at high rates of ventilation) and the limiting flow velocity may be reached, with the potential for airway collapse. Performance is strongly related to the power output at the ‘anaerobic threshold’, and lactate measures provide a guide to an appropriate intensity of endurance training. Peak blood lactate levels are higher in males (commonly 11–19 mmol·l -1 and occasionally as high as 25 mmol·l -1) than in females (9–11 mmol·l -1), probably because males have a greater muscle mass in relation to blood volume. The skeletal muscles are predominantly slow twitch in type, developing an unusual force and power at low contraction velocities. Many rowers have a suboptimal diet, eating excessive amounts of fat. Lightweight rowers also have problems of weight cycling. Aerobic power and muscle endurance often change by 10% over the season, but such fluctuations can be largely avoided by a well-designed winter training programme. Injuries include back and knee problems, tenosynovitis of the wrist and, since the introduction of large blades, fractures of the costae.     

Biology and medicine of soccer: An update

Recent literature on the biology and medicine of soccer (primarily since 1990) has been accumulated by a combination of computer searching of relevant databases and review of the author's extensive files. From a total of 9681 papers, 540 were selected for closer scrutiny and 370 are discussed in the present review. These articles cover patterns of play and the resulting energy demands, the nutritional requirements of soccer, the anthropometric, physiological, biochemical and immunological characteristics of successful players, the influence of environmental stressors (heat, cold, hypoxia and time zone shifts), special features of female and junior competitors, selected issues in training, and the incidence and prevention of injuries. The information presented has important implications for the safety and success of soccer players; the challenge is now to ensure that this information is understood and acted upon by coaches and individual team members.
