The purpose of this study was to compare the pedalling technique in road cyclists of different competitive levels. Eleven professional, thirteen elite and fourteen club cyclists were assessed at the beginning of their competition season. Cyclists’ anthropometric characteristics and bike measurements were recorded. Three sets of pedalling (200, 250 and 300 W) on a cycle ergometer that simulated their habitual cycling posture were performed at a constant cadence (~90 rpm), while kinetic and kinematic variables were registered. The results showed no differences on the main anthropometric variables and bike measurements. Professional cyclists obtained higher positive impulse proportion (1.5–3.3% and P < 0.05), mainly due to a lower resistive torque during the upstroke (15.4–28.7% and P < 0.05). They also showed a higher ankle range of movement (ROM, 1.1–4.0° and P < 0.05). Significant correlations (P < 0.05) were found between the cyclists’ body mass and the kinetic variables of pedalling: positive impulse proportion (r = ?0.59 to ?0.61), minimum (r = ?0.59 to ?0.63) and maximum torques (r = 0.35–0.47). In conclusion, professional cyclists had better pedalling technique than elite and club cyclists, because they opted for enhancing pulling force at the recovery phase to sustain the same power output. This technique depended on cycling experience and level of expertise. 相似文献

We reanalyzed data from published studies (Harp & Mayer, 1997, 1998; Mayer & Moreno, 1998, Mayer et al., 1995, 1996) in which college students learned about the formation of lightning, and were then given open-ended problem-solving question. When asked, “What could you do to decrease the intensity of lightning?,” females were approximately eight times more likely than males to refuse to answer on the grounds that nature cannot be altered. The pattern persisted across four data sets involving 810 participants. The results have practical implications for the design of alternative assessment instruments involving open-ended questions and theoretical implications for gender-based differences in verbal communication styles. 相似文献

ABSTRACT The desire to be close to nature and live in tune with it grew as industrialisation, urbanisation and the impact of technology became increasingly ubiquitous at the turn of the twentieth century. Throughout Europe, model schools were established in rural environments. These private reform schools could not solve the problems of public urban schools. Founded on the initiative of teachers and parents, the Schullandheim (rural school hostel) emerged as a new form bringing urban education and schooling close to nature after the First World War in Germany. Even if related pedagogic activities developed at that time in other countries there is no evidence for comparable institutions. Besides tracing the development of Schullandheime, the article shows how the school hostel idea was embedded in the contemporary educational discussion about the influence large cities had on youth and explores the educational and cultural differences within the school hostel movement through the use of visual material. 相似文献

The aims of this study were (a) to determine whether Spanish children with reading disabilities (RD) show a speech perception deficit and (b) to explore the locus and nature of this perceptive deficit. A group of 29 children with RD, 41 chronological age-matched controls, and 27 reading ability-matched younger controls were tested on tasks of speech perception. The effect of linguistic unit (word vs. syllable) and type of phonetic contrast (voicing, place and manner of articulation) were analyzed in terms of the number of errors and the response time. The results revealed a speech perception deficit in Spanish children with RD that was independent of the type of phonetic contrast and of linguistic unit. 相似文献

While most German anatomy institutes provide only limited information about body donors and their lives, students have expressed a desire to learn more about these individuals, especially about their motivations to donate their bodies for the sake of medical education. In order to gratify this wish, as well as to further humanize body donors, an educational film was compiled, and a study designed to capture the film's effects on medical students. This is the first study using standardized, validated psychological tools to evaluate the impact of an educational film about body donors on students’ empathy and psychological stress levels. The study followed a longitudinal, controlled, and cluster randomized design, including 77 (48 females/29 males) participants who watched the video either before, midway, or after the dissection course. Questionnaires were completed at four points in time applying the Jefferson Scale for Empathy (JSPE-S) and the Interpersonal Reactivity Index (IRI) to measure empathy. Psychological stress levels were recorded by the Brief Symptom Inventory (BSI). Overall, students recommended the film to be shown to all students (median 6.0; maximum on the six-point Likert scale). Viewing the film revealed no significant changes between study groups or over time in JSPE-S sum scores. All groups demonstrated a significant reduction of BSI values before the dissection course actually started and increased values during the course, but both developments appeared not to be associated with the intervention. Overall, the educational film did not correlate with any negative effects on students’ empathy and psychological stress levels, and it was strongly approved of by students, as it provided more humanizing personal information about body donors without violating their anonymity. 相似文献
