Abstract

This study investigated whether hot pack treatment could provide prophylactic effects on muscle damage induced by eccentric exercise of the wrist extensors. Twenty-eight healthy men (age 21±1 years, weight 65±16 kg, height 171±6 cm) were randomly placed into hot pack (n = 14) and control (n = 14) groups. All participants performed an exercise consisting of 300 maximal eccentric contractions of the wrist extensors of the non-dominant arm using an isokinetic dynamometer. A hot pack was applied for 20 min to the wrist extensors of the exercised arm before the exercise for the hot pack group. The control group received no treatment before the exercise. Measured variables included pain intensity assessed by a visual analogue scale and a modified Likert's scale, cold thermal pain threshold, pressure pain threshold (PPT), range of motion in active wrist flexion (ROM-AF) and extension (ROM-AE), range of motion in passive wrist flexion (ROM-PF) and extension (ROM-PE), grip strength, and wrist extension strength. Changes in these variables before, immediately after, and 1 to 8 days following the exercise were compared between groups by a two-way repeated measures ANOVA. All outcome measures from both groups (except for the cold thermal pain threshold of the hot pack group) demonstrated a significant change within the first 2–3 days following exercise. Significant differences between groups were only found at a single point in time for PPT, ROM-PF, ROM-PE and ROM-AE, and the changes were smaller for the hot pack group in comparison to the control group. These results suggest that the prophylactic effects of hot pack treatment on eccentric exercise-induced muscle damage of the wrist extensors are limited.  相似文献

This study was concerned with the interactive role of experience of athletic skill with other relevant environmental variables (display complexity, attentional resources, exposure time of stimuli) on perception (recall) of structured handball game situations. Nineteen experienced (older) and 19 less experienced (younger) handball players were assigned randomly either to ball‐bouncing (diverted attention) or to calm seated (focused attention) conditions. In each of the two conditions, the subjects were exposed to a total of 36 slides containing 2–3, 5–6 and 8–10 players. Eighteen slides were exposed for 0.5 s and 18 for 1.0 s. All the slides contained structured defence and offence situations. Recall scores were subjected to repeated‐measures ANOVA using attention condition and age as between‐subject factors and task complexity and exposure duration as within‐subject factors. The results showed that the recall of less experienced players deteriorated more than the recall of more experienced players following exposure to complex displays (≥ 8 players) while engaging in a secondary task (bouncing). The findings suggest that research paradigms should be applied in the field of sport which share both ecological validity and a potential to discover the cognitive substrates underlying experience and age in skilled motor performance.  相似文献

目前,有关运动性脊髓损伤的研究尚不充分,而且对其损伤机制和治疗方法也没有取得较好的研究进展。随着研究的深入,发现脑源性神经营养因子(BDNF)对促进神经元的存活、受损轴突和神经的再生发挥着重要作用。BDNF转基因疗法将给运动性脊髓损伤的修复和治疗带来巨大的潜力。文章通过分析BDNF及其受体的生物学特性、运动性脊髓损伤的病理特征,为制定运动性脊髓损伤的BDNF基因治疗提供理论基础。  相似文献

The centrality of service learning in the development of students’ professional practice has received worldwide attention. Exposure to appropriately designed service learning experience determines the acquisition of graduate attributes. This article addresses a study in which the key question was: What methods and strategies do students and their clinical supervisors find beneficial in improving their learning experiences during service learning placements? Drawing on the views and experiences of a group of final year occupational therapy (OT) students and their supervisors, the initial focus is on concepts in learning relevant to service learning and professional development, including Vygotsky's zone of proximal development (ZPD), the capability approach and collaborative and peer assisted learning. This is followed by an overview of the methodology and an analysis of the students’ and clinical supervisors’ experiences during service learning. The discussion focuses on the implications of the study findings for practice within a service learning context to enhance the alignment of institutional practices with students’ needs.  相似文献
