分会报告6A -口头报告

在全国范围内，由于缺乏资金，体育部门被迫削减项目. 努力防止这种情况的发生, 学生可能会注意到新的学生费用和学费的增加(乔伊斯), 2019). 该项目的目的是确定在家庭体育比赛期间向成年观众出售酒精是否会成为pp电子极速糖果(CMU)体育系的宝贵收入来源. 这是一项针对当前CMU管理人员的探索性研究. 除了酒类销售本身可能增加的收入之外, the promoting of the general public now being able to purchase alcohol at games could also lead to increased attendance, 导致额外的门票和特许销售. 该项目还将比较和对比其他大学的数据，以了解在体育赛事期间向公众出售酒精是否会限制酗酒以及由此产生的积极或消极后果. 调查问卷将发送给隶属于落基山体育大会(RMAC)的机构的体育管理人员。. 初步结果将用于展示，等待对这些调查的回应.

线粒体, which are responsible for energy creation via aerobic respiration play an important role in human health and physical performance. 适宜有氧运动的个体比不适宜有氧运动的个体有更高的线粒体质量. 类似的, those who are aerobically fit have lower lactate response during submaximal exercise than those who have lower levels of aerobic fitness. Lactate is a by-product of exercise and can be measured via whole blood by a device similar to a blood glucose meter. It has recently been demonstrated that blood lactate response to exercise is a marker of mitochondrial function. 最初的研究建立了乳酸对运动的反应和线粒体功能之间的代理关系，使用了为非常健康的人群设计的分级运动测试方案. 本研究的目的是比较一种改良的(i.e. 较短的)协议到原始(i.e. 长)协议. The modified protocol involves 5 minute stages and resistance increments that are normalized to fat free mass. We hypothesize that our modified protocol will yield the same lactate response to exercise as the original protocol. 本研究的结果可能提供另一种方法来评估血乳酸对运动的反应，这种方法更适合于有氧训练较少的人群.

临床场景:从前交叉韧带(ACL)重建中恢复的个体必须克服身体康复方面的挑战，恢复到受伤前的身体活动水平. 这些挑战可能受到他们受伤的心理感知的影响. 临床问题:在患者重返赛场康复计划中增加心理评估如何提高他们恢复到受伤前活动水平的能力? Summary of Key Findings: Patients who receive an ACL reconstruction have a low return to previous activity level (RPAL) rate. 自我效能感低, 运动恐惧症的坦帕量表得分很高, 高疼痛强度评分, 国际膝关节记录委员会评分, 以及害怕再损伤是与低RPAL率相关的一些心理因素. Psychological assessments used in pre-surgical and post-surgical follow up appointments can be used to predict RPAL. 使用图像作为心理干预与物理康复已被证明有助于愈合过程和促进更好的身体功能评估结果. 临床底线:使用生理干预和物理康复可能会增加身体功能的结果. 这可能会导致更高的自我效能感，减轻患者对再次受伤的恐惧, 导致更高的RPAL速率.

泡沫滚动已被证明可以增加关节的灵活性. There is debate on whether increased joint flexibility will improve characteristics related to vertical jump performance, 特别是动力. 目的:探讨预活性浆液的作用, 臀部, 下肢硬核泡沫滚动对髋关节和膝关节的柔韧性和垂直跳跃性能都有影响, specifically related to momentum during a vertical jump launch in Division II male and female collegiate athletes. 方法:招募20名pp电子极速糖果学生运动员. 受试者将被随机分为滚泡沫组(A)和不滚泡沫组(B)。. 两组都将观看热身录像. 热身后, A组进行泡沫滚动干预，随后进行ROM测量，B组立即进行髋关节和膝关节ROM测量. 然后，两组选手将在测力板上进行垂直跳跃. Hypothesis: We hypothesize that foam rolling will increase ROM and improve momentum during a vertical jump test.

场景:由于脑震荡的症状和大脑愈合所需的时间，脑震荡患者在康复期间通常很难回到教室. 在这个过渡期间，可以提供学术住宿来支持这些人. Question: Do academic accommodations increase a person's readiness to return to class while recovering from a concussion? Key findings: Those who are diagnosed with a concussion experience greater academic dysfunction at one-week and one-month post diagnosis. 那些被确诊的, only 45% were receiving accommodations at one-week post injury and 31% were using accommodations at the one-month mark. 对于那些确实寻求住宿的人，可以提供不同程度的支持. 为了给学生提供成功所需的所有工具，他们必须与教育工作者合作, 管理员, 以及医疗保健提供者建立个人计划. 个人回到以前的学术水平的计划不能以时间为基础. 总结:通过为遭受脑震荡的学生提供符合他们个人需求的学术住宿，他们为最终重返课堂做了更多的准备.

腹部张力是一种在康复训练中经常使用的强化技术. 吸气(DI)是一种常见的腹部张力技术，利用呼吸来帮助激活腹部肌肉，更具体地说, 腹横肌(TA)在更大程度上帮助呼吸. The DI technique has been shown to improve abdominal activation and coordinated muscular support of the trunk (Kim & (Boyle, Olinick & 刘易斯,2010). 我们研究的目的是通过观察对最大握力(MGS)的影响来确定腹部张力是否会对远端区域产生影响。. 我们假设在使用DI技术激活腹部时进行握力测试可以通过增加运动单元的招募来增加MGS. 11名参与者完成了这项研究. 每个受试者进行两次对照试验和两次实验试验. Participants performed the CON and experimental trials twice with breaks between each trial for both dominant and nondominant hands. 结果显示CON组与实验组的MGS无显著差异, p值为0.60. 总之, our results indicate that using the DI technique while performing a grip strength test does not increase MGS.

目的:确定排球运动员在入路跳落地阶段的表面肌电图(EMG)是否有差异，以及是否有和没有T2活动踝关节支具对垂直跳有影响. 方法:使用表面肌电图对胫骨前肌进行肌肉激活评估, 比目鱼肌, 侧腓肠肌, 和内侧腓肠肌之间的两种情况:没有踝关节支架和T2支架. 受试者在两种情况下都完成了最大垂直跳跃，并使用每块肌肉的最大随意收缩将肌电图数据标准化. 结果:踝关节支架对比目鱼肌表面肌电无显著影响, 侧腓肠肌, 和内侧腓肠肌(P > 0.0.05)，但前胫骨的激活明显增加(P = 0.05).016)，与没有脚踝支架相比. 不同条件下的垂直跳跃高度无显著差异. 结论:T2支具仅能显著改变前胫表面肌电图. 另外, there were no changes in vertical jump height suggesting ankle braces do not negatively affect vertical jump height performance. 因此, athletes who choose to wear ankle braces as a prophylactic measure shouldn be concerned with jumping performance when wearing them.

背景:几项研究(Sotiropoulos等)., 2010; Crow et al., 2012) showed the effects of a gluteal and hamstring targeted warm-up on performance and surface voltage, 然而, 这些研究评估的是跳跃表现，而不是肌电活动. 此外, 关于在有针对性的热身中使用阻力带的效果的研究有限. 目的:这个项目的目的是确定在中等负荷下下蹲时，以臀肌和腿筋为目标的阻力带热身是否会对表面电压产生影响. 方法:单腿股内侧肌表电压肌电图, 股外侧肌, 臀大肌和股二头肌将取自六名NCAA女大学游泳运动员. Subjects will perform a set of five tempo controlled (3-1-3-2) moderate load (60% of body weight) back squats after a general warm-up. The intervention performed after control set consists of five resistance band exercises targeting the hamstring and gluteal muscle groups. Participants will then perform another set of five back squats under the same conditions as the control set. 假设:我们假设，与对照组相比，有针对性的阻力带热身会增加干预后臀大肌和股二头肌的平均表面电压.

研究表明加重的毯子, vests and compressive vests may have positive outcomes related to proprioceptive input for spectrum disorders as well as cerebral palsy. 目的:本研究的目的是评估健康的大学年龄被试，并探讨负重背心对身体质心的影响。, 姿势摇摆中心(COP)和步态. 方法:对15名健康大学生进行单足平衡测试和步态周期评估，并分别在负重背心和不负重背心的情况下进行. 参与者将首先接受无体重的COM、COP和步态检查. 然后受试者将被要求佩戴9号.8 kg weighted vest for 45 minutes and then be reassessed in a similar fashion to the control condition. Hypothesis: We hypothesize that the weighted vest will decrease postural sway and there will be an improvement to gait cycle. Conclusion: Positive results in a healthy population could be investigated with other populations such as spectrum and CP.

Electromyography is a technique for evaluating and recording the electrical activity produced by skeletal muscles. The EMG technology can be used to compare muscle activity during different resistance training exercises. 目的:本研究的目的是比较胸大肌的肌电活动, 前三角肌, 在一组杠铃平板卧推和哑铃平板卧推时，肱三头肌外侧. Methods: This study is using division 2 college football linemen lifting a weight that is 40% of their barbell bench press one rep max. 肌电导联将放置在胸大肌，三角肌前肌和肱三头肌外侧. 在完成他们典型的热身动作之后, 受试者将做一组杠铃卧推，每组6次, 短暂的休息, 然后做哑铃卧推，每组6次. 假设:我们假设在所有观察到的肌肉中，哑铃卧推时的肌电图活动比杠铃卧推时更多.

医师和高级执业医师(APP)职业倦怠是医学界日益关注的问题. High-stress levels and low work-life balance contributes to physicians and APPs being more likely to experience burnout than any other career. Mini Z倦怠调查被发送给科罗拉多州西部的医生和应用程序提供商. Mini Z职业倦怠调查是衡量医生和app职业倦怠的有效工具. 这些调查将被打分, and statistical analysis will be performed to determine a baseline level of the current burnout reported by providers in Western Colorado. This study is important because no previous research has been published on physician and APP burnout in Western Colorado.
