The present investigation was carried out to examine the incidence and pattern of injuries in adolescent multisport athletes from youth sports academy. Injury data were prospectively collected from 166 athletes during the seasons from 2009 to 2014. A total of 643 injuries were identified, 559 (87.0%) were time-loss injuries. The overall injury incidence was 5.5 (95% confidence interval CI: 5.1–6.0), the incidence of time-loss injuries was 4.8 (95% CI: 4.4–5.2), the incidence of growth conditions was 1.2 (95% CI: 1.0–1.4) and incidence of serious injuries was 0.6 (95% CI: 0.5–0.8) per 1000?h of exposure. The prevalence of overuse injuries was 50.3%. Growth conditions represented 20.0%. Most of the injuries (67.0%) involved the lower extremities, and both foot and ankle were the most predominant injured body parts (22.0%). Knee injuries were mostly from overuse (50 vs. 23, p?=?.02), whereas foot and ankle injuries resulted from an acute mechanism (94 vs. 31, p?<?.0001). Minor and moderate injuries accounted for 87.0%. Muscle, tendon and osteochondrosis injuries accounted for 52.0% of all injuries. Comparing groups, squash sport was having the highest injury incidence (8.5 injuries per athlete). Higher exposure was associated with greater overuse relative risk (RR?=?1.03, 95% CI: 1.01–1.014, p?<?.001). In conclusion, the results of this study identified a high incidence of injuries in this youth sports population. Striking was the prevalence of overuse injuries of 50%, which suggests the need for injury prevention protocols for adolescent highly trained athletes. 相似文献

The purpose was to assess sleep patterns, quantity and quality in adolescent (16.2?±?1.2 yr) Middle Eastern academy soccer players (n?=?20) and the influence of an intermission upon these characteristics. On a 17-day training camp (located one time zone west of home) including three discrete matches, sleep was assessed pre- (PRE) and post-match (POST) via wrist actigraphy. Retrospective actigraphy analysis identified sleep characteristics, including if players experienced a sleep intermission (YES) or not (NO) proximal to dawn, and bedtime (hh:mm), get-up time (hh:mm), time in bed (h), sleep duration (h) and sleep efficiency (%). Within YES two bouts were identified (BOUT1 and BOUT2). No differences were seen between PRE and POST, nor between BOUT1 and BOUT2 (p?>?.05). Overall players did not meet National Sleep Foundation (NSF) guidelines (7:04?±?1:16?h vs. recommended 8–10?h for 14–17 yr). Sleep duration was significantly reduced (～ ?13% or ?1:06) in YES compared to NO (6:33?±?1:05 vs. 7:29?±?1:17, p?<?.01). Despite players in YES waking earlier due to an intermission, they did not compensate for this with a later wake time, rising significantly earlier compared to NO (09:40?±?00:38 vs. 10:13?±?00:40, p?<?.05). These players on average do not obtain sufficient sleep durations relative to NSF guidelines, with decrements increased by an intermission proximal to dawn. High inter- and intra-individual variance in the players sleep characteristics indicates the need for individualized sleep education strategies and interventions to promote appropriate sleep. 相似文献

This study is a comparative analysis of the environmental philosophies of college undergraduates enrolled in a Midwestern university. Two courses were used for the research, one from a recreation management curriculum and the other from environmental studies. The study utilized a survey instrument called the Environmental Action and Philosophy Matrix to determine the extent to which students’ environmental attitudes are based on scientific or religious rationale, as well as anthropocentric or biocentric perspectives. Findings show students to possess scientific underpinnings for their viewpoints, regardless of anthropocentric or biocentric tendencies. In addition, the environmental studies students displayed more biocentric attitudes than the recreation management students. 相似文献

The purpose of the study reported on was to investigate the current classroom practices of teachers. Using multistage sampling, 245 teachers were selected from primary and secondary schools in the Amhara Region and Addis Ababa City, Ethiopia. A survey design was used for the study. The major results obtained showed that problems were observed in implementing active teaching methods; applying a variety of assessment techniques; questioning skills; providing feedback; managing classroom behaviour; and establishing a positive classroom climate. The study results revealed that primary school teachers performed better than secondary school teachers and also female teachers performed better than male teachers in most teaching-learning activities; but there was no difference in terms of regions for most teaching-learning activities. Some of the recommendations are: training on active learning methods and assessment; providing feedback; student management; action research; and so on. 相似文献

Exploring Saudi Computer Science Teachers’ Conceptual Mastery Level of Computational Thinking Skills
The Ministry of Education in Saudi Arabia implemented a new computer science curriculum in 2008. There was speculation that many computer science teachers did not possess sufficient knowledge of computational thinking needed to teach this subject. To investigate this topic, a quantitative research study was conducted with 55 male computer science teachers in Riyadh, Saudi Arabia. Results of the study revealed that most of the computer science teachers had a low conceptual level of computational thinking, and some of the teachers had misconceptions about the exact nature of computational thinking. Findings indicated that computer science teachers did indeed need more training in what computational thinking means and how to teach this subject. 相似文献
