The coronal and sagittal plane leg movements of 24 experienced male cyclists were assessed using video analysis while cycling on a Kingcycle windload simulator. The cyclists were grouped into those with a history of injury and an asymptomatic group on the basis of self-reported injury status. The ages, cycling experience, competition distances and competition speeds of the two groups were compared using Student's t-test. No significant differences (P < 0.05) were found for any of these variables. The maximum and minimum shank adduction, shank adduction velocities, knee flexion and ankle dorsiflexion values were also compared using Student's t-test. Significant differences were found at the point of maximum adduction (1.9 degrees; P = 0.019) and minimum dorsiflexion (4.9 degrees; P = 0.014). These differences indicated more dorsiflexion and greater abduction on the part of the symptomatic cyclists, supporting previous research that found that cyclists with a history of injury differ from those without a history of injury in the coronal plane leg movement patterns they adopt. Also, the most extreme medial position of the knee relative to the ankle occurred during knee extension. This supports the potential injury mechanism proposed by Francis (1986), which had previously only been examined using coronal plane kinematics. 相似文献

This research examined varying levels of physical activity and psychomotor and physiological function in variously active older men. Very active moderately active, and low active participants were tested on simple (SRT) and choice reaction time (CRT), coincidence-anticipation timing (CAT), and VO2max. No significant differences for age or height were found, although percentage of fat, and weight were statistically different. Active groups were leaner and lighter. VO2max was significantly different between groups, as physically active groups yielded geater values. SRT and CAT also yielded significantly different results with more active participants showing better performance. No between-groups significant differences resulted for CRT. Generally, increased levels of physical activity were related to superior physiological outcomes and improved psychomotor peformance. 相似文献

This paper focuses attention on the early childhood teacher's place in the research community. It provides a look at the teachers' perspectives of research and then points out ways and reasons for early childhood teachers to become more active as classroom researchers, research partners and consumers of research through pre-service and in-service opportunities. After providing a definition of teacher research as systematic inquiry into one's own classroom, it discusses the value of such research and identifies historical support for it. The paper presents examples of partnership research using a video camera as a tool for data collection and teachers' reactions to it. It also provides quotes of individual teacher's introduction to teacher research and some points to consider in embarking on classroom research. Cette conference traite de la place de l'enseignant de la petite enfance dans le monde de la recherche. Nous allons examiner les perspectives des enseignants en matiere de recherche, puis indiquer comment et pourquoi rendre les enseignants de la petite enfance plus actifs en tant que chercheurs dans le cadre de la classe, partenaires de recherche et consommateurs de recherche grace a des opportunites offertes avant et pendant leur enseignement. Apres avoir fourni une definition de la recherche des enseignants en tant qu'examen systematique de leur propre classe, nous examinerons la valeur de cette recherche a l'aide d'une camera video comme outil de collecte de donnees et les reactions des enseignants. Nous citerons egalement l'opinion d'enseignants formes a cette recherche et nous signalerons quelques aspects a considerer avant de lancer une recherche en classe. Esta charla centra su atencion en la posicion del profesor de pequenos en la comunidad investigadora. Ofrece un idea de las perspectivas de investigacion de los profesores y luego senala maneras y razones para que los profesores de ninos pequenos sean mas activos como investigadoes de clase, socios de investigacion y consumidoes de investigacion a traves de oporunidades de preservicio y en servicio. Despues de facilitar una definicion de la investigacion de profesores como encuesta sistematica del aula propia, se habla del valor de dicha investigacion y se identifica un apoyo historico para la misma. Esta charla presenta ejemplos de investigacion conjunta usando videocamara como herramienta para la recopilacion de datos y reacciones de los profesores. Tambien ofrece citas de introducciones individuales de profesores a la investigacion de profesores y algunos puntos a considerar al emprender la investigacion de una clase. 相似文献
