The Use of Communication Technology in Thailand's Political Process     

Nalinee Joy Taveesin PhD  William J. Brown 《亚洲交流杂志》2013,23(1):59-78

Thailand's political landscape has changed dramatically during the past five years. The rapid growth of communication technology in Thailand has been instrumental in generating political participation in the national elections of 2001 and 2005. In this article we provide the results of a benchmark study that assesses the early period of this political transformation. Specifically, we examined the use of television and of the Internet for political information by interviewing 500 urban residents. Our results indicate that likely voters actively gathered political knowledge from television advertisements and political party websites. Although use of television and the Internet for political purposes did not increase direct involvement in political parties, it did promote participation in the 2001 national election. Implications of these findings for future research on the use of communication technology for political communication in Asia are discussed.  相似文献   

卧推练习与实心球练习对篮球中双手长传球距离的影响     

郑鑫 《山东体育科技》2012,34(4):43-45

以山东体育学院篮球队12名队员为实验对象,通过实验比较卧推练习与实心球练习对长传球距离的影响,以加深对篮球长传球技术特性、本质的认识与理解,以获得有益的借鉴和启示。结果显示,为期12个周的力量训练后,无论在远度方面,还是在短传快攻的时间及3分外围短传时间方面实心球练习的效果都显著优于卧推练习。实心球练习手段是结合专项的力量素质练习,能有效地提高双手胸前传球的远度与速度,为短传、长传快攻的成功打下良好的基础。建议在今后的训练中将实心球训练纳入篮球专项训练之中。  相似文献

Effects of agonist–antagonist complex resistance training on upper body strength and power development     

Daniel W. Robbins  Warren B. Young  David G. Behm  Warren R. Payne 《Journal of sports sciences》2013,31(14):1617-1625

Abstract

The objective of this study was to examine the chronic effects on strength and power of performing complex versus traditional set training over eight weeks. Fifteen trained males were assessed for throw height, peak velocity, and peak power in the bench press throw and one-repetition maximum (1-RM) in the bench press and bench pull exercises, before and after the eight-week programme. The traditional set group performed the pulling before the pushing exercise sets, whereas the complex set group alternated pulling and pushing sets. The complex set training sessions were completed in approximately half the time. Electromyographic (EMG) activity was monitored during both test sessions in an attempt to determine if it was affected as a result of the training programme. Although there were no differences in the dependent variables between the two conditions, bench pull and bench press 1-RM increased significantly under the complex set condition and peak power increased significantly under the traditional set condition. Effect size statistics suggested that the complex set was more time-efficient than the traditional set condition with respect to development of 1-RM bench pull and bench press, peak velocity and peak power. The EMG activity was not affected. Complex set training would appear to be an effective method of exercise with respect to efficiency and strength development.  相似文献   

A comparison of muscle activity and 1-RM strength of three chest-press exercises with different stability requirements     

Atle H. Saeterbakken  Roland van den Tillaar  Marius S. Fimland 《Journal of sports sciences》2013,31(5):533-538

Abstract

The purpose of this study was to compare one-repetition maximum (1-RM) and muscle activity in three chest-press exercises with different stability requirements (Smith machine, barbell, and dumbbells). Twelve healthy, resistance-trained males (age 22.7 ± 1.7 years, body mass 78.6 ± 7.6 kg, stature 1.80 ± 0.06 m) were tested for 1-RM of the three chest-press exercises in counterbalanced order with 3–5 days of rest between the exercises. One-repetition maximum and electromyographic activity of the pectoralis major, deltoid anterior, biceps, and triceps brachii were recorded in the exercises. The dumbbell load was 14% less than that for the Smith machine (P ≤ 0.001, effect size [ES] = 1.05) and 17% less than that for the barbell (P ≤ 0.001, ES = 1.11). The barbell load was ～3% higher than that for the Smith machine (P = 0.016, ES = 0.18). Electrical activity in the pectoralis major and anterior deltoid did not differ during the lifts. Electrical activity in the biceps brachii increased with stability requirements (i.e. Smith machine <barbell <dumbbells; P ≤ 0.005; ES = 0.57, 1.46, and 2.00, respectively), while triceps brachii activity was reduced using dumbbells versus barbell (P = 0.007, ES = 0.73) and dumbbells versus Smith machine (P = 0.003, ES = 0.62). In conclusion, high stability requirements in the chest press (dumbbells) result in similar (pectoralis major and anterior deltoid), lower (triceps brachii) or higher (biceps brachii) muscle activity. These findings have implications for athletic training and rehabilitation.  相似文献   

The 1936 Olympic Games in Berlin: The Response of America's Black Press     

David K. Wiggins 《Research quarterly for exercise and sport》2013,84(3):278-292

Abstract

Eighty-seven female masters swimmers ranging in age from 20 to 69 were selected for a detailed study of their body composition and physiological responses at rest and during exercise. These women were then placed into two subsets, a highly trained group and a not highly trained group, on the basis of the frequency, duration, and intensity of swimming workouts. Significant differences were detected when comparing the highly trained and not highly trained subjects on measures of weight, body density, percent fat and lean body weight (p<.05). Significant differences which favored the highly trained group were also seen when comparing these same two groups for [Vdot]_E max, [Vdot]O₂ max (1/min), [Vdot]O₂ max (ml·kg^–1·min^–1), [Vdot]O₂ max (ml·kg·LBW^–1·min^–1), O₂ pulse (ml·kg^–1·beat^–1), and O₂ pulse (ml·kg·LBW^–1). Both the highly trained and not highly trained swimmers were considerably lower in percent fat than previously reported data for normal untrained women of similar ages. In both groups, however, percent fat across age levels within each training group showed significant increases at approximately 40 years of age (p<.05). In the highly trained swimmers, [Vdot]O₂ max (ml·kg^–1·min^–1) decreased at a mean rate of about 7% per decade, while in the not highly trained swimmers the decline was approximately 8% per decade. It appears that the rate of decline in [Vdot]O₂ max in women with aging may be independent of training status.  相似文献   

Validity of Palpation Recovery Pulse Rate to Estimate Exercise Heart Rate Following Four Intensities of Bench Step Exercise     

Nancy L. Greer  Frank I. Katch 《Research quarterly for exercise and sport》2013,84(4):340-343

Abstract

Previous investigations regarding activity during the post-knowledge of results (KR) interval have considered the performance of interference groups over KR-supplied acquisition trials as indicative of effects upon learning. The absence of transfer tests in these studies, however, preclude such an assumption. Indeed, the use of a retention test in the present investigation (no-KR trials following an interpolated phase) provided evidence suggesting that, while activity during the post-KR interval is detrimental to performance, no such assumption can be made regarding this effect upon learning. These findings are discussed relative to recent arguments that some of the commonly accepted “Laws of KR” may be contradictory when applied simultaneously to motor learning and performance.  相似文献   

The Birth of the Sports Press in Spain Within the Regenerationist Context of the Late Nineteenth Century     

Xavier Torrebadella-Flix 《国际体育史杂志》2013,30(18):2164-2196

This study tackles the birth and development of the sports press in Spain from 1865 to 1899, linked to the need of a bourgeois society to emulate the English lifestyle, characterised by the sports craze. The sports press in Spain fitted extremely well in the late nineteenth century, encouraged by the Regenerationist movement. This is clear by the growth in number of sports publications, by the promotion of physical culture by Regenerationism and by the use of such publications to spread Regenerationism's approach to sport. Both primary and secondary sources were used in the research process. With regard to primary sources, archives containing specific documentation on the origins and early years of the sports press in Spain were examined. A total of 85 sports publications were counted in 18 different towns, but mostly concentrated in Madrid (28) and Barcelona (24). The most widely represented sports in these were cycling (25) and hunting (18). Among those publications that were not specific to one sport, 13 titles included the English-language term ‘sport’, and only two incorporated the newly coined Spanish word, ‘deporte’. Los Deportes (1897–1910) is the most important publication of this period and the foundation stone of modern sports journalism in Spain.  相似文献   

Techniques and considerations for determining isoinertial upper‐body power     

Michael J. Falvo  Brian K. Schilling  Lawrence W. Weiss 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(2):293-311

Power is an integral aspect of many sports. Although power output of the lower body is often measured during jumping and cycling movements, much less is known about power as pertains to the upper body musculature. Recently, isoinertial methods ‐ with constant gravitational load ‐ of power testing have become common, but little is known of the reliability and criterion validity of these tests as they pertain to sport performance. In addition, the varied methodology makes a lucid model more evasive. The aims of this review are to examine the various methods of assessing upper body power, to establish its role in predicting athletic performance, and to assess the body of literature that has assessed power output of the upper extremities by isoinertial methods. To our knowledge, only two studies on isoinertial upper‐body power have shown a direct correlation to sporting ability (Baker, 2001; Baker et al., 2001); therefore, many unanswered questions exist as to the efficacy of these tests as predictors of athletic ability or as a method to track athletes’ training over time. From this review we hope to allow the sport coach to assess the overall utility of these tests in terms of availability, safety and external validity.  相似文献
