We evaluated the impact of bilateral leg extension power and fat-free mass on 2000?m rowing ergometer performance in 332 young oarsmen (age 21±2 years, height 1.76±0.05?m, body mass 62±6?kg; mean±s). The 2000?m rowing performance time was correlated with height (1.62–1.93?m; R 2?=?0.23, P?<0.001), body mass (53–95?kg; R 2?=?0.53, P?<0.001), fat-free mass (47–82?kg; R 2?=?0.58, P?<0.001) and bilateral leg extension power (1202–3302?W; R 2?=?0.38, P?<0.001). Multiple regression analysis selected fat-free mass and bilateral leg extension power as regressor variables. Fat-free mass explained 58% of the variability in rowing performance and the inclusion of bilateral leg extension power improved the power of prediction by 5%. The results suggest that rowing involves almost every muscle in the body and that bilateral leg extension power is very important during this activity. 相似文献

The Japanese Private University is viewed as a modern socialization system for processing youth into leadership positions in business and industry. A “degreeocracy” and an “assimilation” hypothesis were proposed to explain the process of psychological development through the university. The “degreeocracy” hypothesis ascribes a utilitarian view of one's certification by a particular university. According to this hypothesis, students will come to shape their behaviors and attitudes to be compatible with the “degree” as they progress from freshmen to seniors. In contrast, the “assimilation” hypothesis denotes that the extent to conforming to, and identifying with the norms and goals of the university will depend upon social and educational background. Three groups differing in terms of the potential for assimilation were identified based upon social and educational background. Data were collected from samples of freshmen, sophomores, juniors, and seniors majoring in engineering in one of the largest private universities in Japan. Results supported both hypotheses. Differences among “assimilation” subgroups were significant but these differences were not exacerbated over grade year. The findings are discussed in terms of the particular nature of the private university and the larger employment system for college graduates in Japan. 相似文献

This paper point out that utilizing fully the community-based information networks based on multimedia digital networking Information Technology (IT) makes it possible to formulate a new customer value creation business model. Aggressive IT investment by top management to build community-based information networks, a support tool for this future network strategy, will permit business innovation based on strengthened competitiveness and enhanced customer service. 相似文献
