Injury rate,mechanism, and risk factors of hamstring strain injuries in sports: A review of the literature

Hamstring strains are one of most common sports injuries. The purpose of this literature review is to summarize studies on hamstring strain injury rate, mechanism, and risk factors in the last several decades with a focus on the prevention and rehabilitation of this injury. Hamstring injury commonly occurs in sporting events in which high speed sprinting and kicking are frequently performed, such as Australian football, English rugby, American football, and soccer. Basic science studies have demonstrated that a muscle strain injury occurs due to excessive strain in eccentric contraction instead of force, and that elongation speed and duration of activation before eccentric contraction affect the severity of the injury. Hamstring strain injury is likely to occur during the late swing phase and late stance phase of sprint running. Shortened optimum muscle length, lack of muscle flexibility, strength imbalance, insufficient warm-up, fatigue, lower back injury, poor lumbar posture, and increased muscle neural tension have been identified as modifiable risk factors while muscle compositions, age, race, and previous injuries are non-modifiable risk factors. The theoretical basis of some of these risk factors, however, is lacking, and the results of clinical studies on these risk factors are inconsistent. Future studies are needed to establish the cause-and-effect relationships between those proposed risk factors and the injury.     

高压氧对急性力竭性运动后血脂质过氧化物和超氧化物歧化酶代谢的影响

为了探讨ＨＢＯ对力竭性运动后机体氧自由基代谢的影响，让２０名体育系男大学生在自行车功率计上运动至力竭，然后随机分成ＨＢＯ组和对照组，他们分别在ＨＢＯ和自然状态下恢复约１２０Ｍｉｎ。在运动前、运动后和运动后２小时（恢复期）测定血清ＬＰＯ含量和ＳＯＤ活力。实验结果表明：短时间的力竭性运动使机体氧自由基的产生和清除处于一种高水平状态，并不破坏其平衡；适当的ＨＢＯ可以提高机体清除氧自由基的能力，有利于运动疲劳的恢复。

乾隆养生术对老年人形态、生理和生活能力影响的研究

摘 要：随着社会的进步,全球都面临着日趋严峻的老龄化问题,我国也不例外,这将给个人、家庭、社会和国家增加极大的负担,影响人们生活的幸福度。因此,研究如何改善老年人健康水平,提高其生活能力,具有重要意义。本研究采用实验法,以乾隆养生术为练习手段,选取中央民族大学老年大学和太申祥和山庄的30名老年人为实验对象,通过对受试者练功4个月前后某些形态、生理、血液和生活能力等指标的测试和统计分析发现：练习乾隆养生术,可明显改善不同年龄老年人的生理功能、血脂和生活自理能力,进而提高其生活质量,并且没有任何副作用,也可以很好的避免损伤。研究建议有关部门大力推广乾隆养生术,并进一步开展对乾隆养生术机理和文化内涵的研究。     

Web-based parenting skills to reduce behavior problems following abusive head trauma: A pilot study

Pediatric abusive head trauma causes significant cognitive and behavioral morbidity, yet very few post-acute interventions exist to facilitate long-term recovery. To meet the needs of this vulnerable population, we piloted a web-based intervention with live coaching designed to improve positive parenting and child behavior. The efficacy of this parenting skills intervention was compared with access to Internet resources on brain injury. Participants included seven families (four randomized to the parenting intervention and three randomized to receive Internet resources). Parenting skills were observed and child behavior was rated at baseline and intervention completion. At completion, parents who received the parenting skills intervention showed significantly more positive parenting behaviors and fewer undesirable behaviors during play than parents who received access to Internet resources. Additionally, during play, children in the parenting skills intervention group were more compliant following parent commands than children in the Internet resources group. Lastly, parents who received the parenting intervention reported less intense oppositional and conduct behavior problems in their children post-intervention than did parents in the Internet resources group. These findings provide preliminary evidence for the use of this web-based positive parenting skills intervention to improve parenting skills and child behavior following abusive head trauma.
