作者宣称，他们有没有竞争的财务权益。

连续数据跟踪技术使锻炼坚持的一个非常精确的测量。这个程序可以通过与目标功率，水平，速度，或Met水平目标取代心脏速率范围内很容易地适应坚持的其他定义。在本例中，热身和冷却阶段被淘汰隔离，因为我们的具体研究对象的运动阶段。应该热身和冷却阶段会感兴趣的其他研究人员，步2.3（"消除nontraining阶段"）可以从协议被淘汰。此外，该硬件和软件也可用来测量粘附到其它模式的训练，诸如跑步机，椭圆形，步进，并且臂测力计。 按照上述协议时，一些简单的步骤是至关重​​要的。首先，CardioMemory软件必须在运动器材（ 例如 ，功率自行车）前开始锻炼数据是TRAC糟透了和随后记录。应数据在该初始步骤被丢失，数据提取协议将需要作相应调整。其次，干扰源必须被最小化，以降低串扰和/或数据丢失的风险。的心脏速率监视器的设备和软件进行无线通讯。因此，如果使用目标心脏率计算粘附干扰尤为不利。最后，当务之急是要选择有允许对大量数据的能力，数据库统计软件。例如，在与10名学员完成36节在每个40分钟的研究，864,000行的数据点将会产生。 Excel 2007和更高版本必须包含1,048,576行的工作表23的容量，而24的SAS和SPSS 25没有限制的行数。取决于预期的一个给定的学习数据点的总数，软件需要被相应地选择。 </p&gt; 尽管这种技术的显着优点，有两个主要的限制存在。第一是数据丢失，这可能会导致从设备和/或软件故障。如上面提到的，数据损失可能是由于与无线设备（ 即移动电话或Wi-Fi）的电气干扰，并且更具体地与心脏率的无线数据传输的干扰。然而，有时，数据丢失也可以是由于无法识别的原因。第二个限制是，该软件不提供标记或系统分裂运动方案，以区分/识别不同阶段的选择。如果这个选项是可用的，所关注的运动阶段的提取可以直接在软件中执行，这将限制在遵守协议的计算步骤。还有，将标记的办法是不切实际的坚持间隔或间歇训练方案的研究，这将允许不同阶段（ 如 。低与高强度）的分化。 对于未来的前景，利用连续的数据跟踪技术来精确地量化坚持将使研究人员能够观察运动反应的模式，以不同的干预措施，确定坚持的决定因素和表征，差的遵从。最终，更好地理解运动坚持将允许运动康复计划的优化。

肺康复（PR）的结合运动训练，患者教育和心理支持，并得到广泛公认的肺病1-5的管理基石。公关的目的是减轻症状，优化功能状态，提高生活健康质量，降低医疗费用4,5。在一项荟萃分析的随机31在慢性阻塞性肺疾病（COPD）对照试验，公关被证明显著提高运动能力，减轻呼吸困难和疲劳，改善情绪的功能，并加强对他们的状况6控制病人的意识。此外，证据记录其在减少住院8-13花费呼吸加重7天效果。运动训练被认为是成功的关键在于公关，因为它负责许多与此干预3-5带来的好处。然而，有几个的重大课题患者是秉承建议运动量或水平。不依从推荐的治疗可能导致治疗干预的失败，以及低效利用卫生资源14。 据世界卫生组织，术语&#39;&#39;&#39;&#39;坚持是指在何种程度上与由专业医务人员15给出建议，一个人的行为相吻合。迄今为止，坚持康复锻炼的设置培训已基本评定为参与任率（ 即 ，登记程序），完成率（ 即整理程序），或出席率（ 即行使号会议出席）16-18。目前，还没有"金标准"的存在，用于测量坚持15和当前方法不允许进行非常精确。此外，取决于所选择的METHOD，坚持公关率已经显示很大的变化16-19。例如，霍格等人在COPD患者16测量遵守那些谁完成了程序的简称，发现约40％的低依从性之间的比率。然而，已经使用的出席率其他公关的研究表明，平均而言，90％的依从10,20,21。在同质化计算坚持的缺乏使得它很难进行比较研究的结果。另一个值得关注的是缺乏精度与现有的计算方法;参加到运动训练并不保证遵守规定的强度。在信息这种差距导致我们研究如何坚持能以更精确的方式来计算。 在健身器材技术的最新进展已经允许连续的数据跟踪，它可以被用来监视遵守规定的有氧训练强度时individu在公关方面人锻炼。更具体地讲，数据跟踪硬件和软件许可证的持续时间的第二逐秒记录，速度级别，瓦数，速度，心脏速率，距离，卡路里消耗，VO 2，METS和热量，并提供所有变量的平均值与除了 ​​水平和VO 2。该技术的主要优点是可以连续录制的具体措施，允许坚持的精确计算，以运动处方与以前报道的一般出席或完成率的能力。这个过程可以是价值的任何研究探讨的一个或几个有氧运动训练方案的影响。使用这种技术，患者坚持规定的强度可以通过在过程中每个环节的训练阶段指定的瓦数，水平，速度，或心脏速率所花费的时间百分比来评估。对于我们的调查，坚持锻炼培训协议已被定义为百分比时间指定的目标心脏率范围之内度过的。由于在给定的亚极量负荷心脏率响应心肺适能的增加减少，这种方法可确保患者保持在相同的相对（而不是绝对）的训练强度在整个程序。本协议详细描述了如何连续数据跟踪技术可用于精确测量遵守规定目标心脏率范围。

Manual Muscle Testing:  A Method of Measuring Extremity Muscle Strength Applied to Critically Ill Patients

Survivors of acute respiratory distress syndrome (ARDS) and other causes of critical illness often have generalized weakness, reduced exercise tolerance, and persistent nerve and muscle impairments after hospital discharge.1-6 Using an explicit protocol with a structured approach to training and quality assurance of research staff, manual muscle testing (MMT) is a highly reliable method for assessing strength, using a standardized clinical examination, for patients following ARDS, and can be completed with mechanically ventilated patients who can tolerate sitting upright in bed and are able to follow two-step commands. 7, 8 
This video demonstrates a protocol for MMT, which has been taught to &ge;43 research staff who have performed &gt;800 assessments on &gt;280 ARDS survivors. Modifications for the bedridden patient are included. Each muscle is tested with specific techniques for positioning, stabilization, resistance, and palpation for each score of the 6-point ordinal Medical Research Council scale.7,9-11 Three upper and three lower extremity muscles are graded in this protocol: shoulder abduction, elbow flexion, wrist extension, hip flexion, knee extension, and ankle dorsiflexion. These muscles were chosen based on the standard approach for evaluating patients for ICU-acquired weakness used in prior publications. 1,2.

Survivors of acute respiratory distress syndrome (ARDS) and critical illness frequently develop long-lasting muscle weakness. Manual muscle testing (MMT) is a standardized clinical examination commonly used to measure strength of peripheral skeletal muscle groups. This video demonstrates MMT using the 6-point Medical Research Council scale.

Development of an Algorithm to Perform a Comprehensive Study of Autonomic Dysreflexia in Animals with High Spinal Cord Injury Using a Telemetry Device

Spinal cord injury (SCI) is a debilitating neurological condition characterized by somatic and autonomic dysfunctions. In particular, SCI above the mid-thoracic level can lead to a potentially life-threatening hypertensive condition called autonomic dysreflexia (AD) that is often triggered by noxious or non-noxious somatic or visceral stimuli below the level of injury. One of the most common triggers of AD is the distension of pelvic viscera, such as during bladder and bowel distension or evacuation. This protocol presents a novel pattern recognition algorithm developed for a JAVA platform software to study the fluctuations of cardiovascular parameters as well as the number, severity and duration of spontaneously occurring AD events. The software is able to apply a pattern recognition algorithm on hemodynamic data such as systolic blood pressure (SBP) and heart rate (HR) extracted from telemetry recordings of conscious and unrestrained animals before and after thoracic (T3) complete transection. With this software, hemodynamic parameters and episodes of AD are able to be detected and analyzed with minimal experimenter bias.

The catheter of a telemetry device is implanted into the abdominal aorta in order to continuously collect beat-by-beat hemodynamic data from animals pre and post-high thoracic spinal cord transection.

Assessment of Pulmonary Capillary Blood Volume, Membrane Diffusing Capacity, and Intrapulmonary Arteriovenous Anastomoses During Exercise

Exercise is a stress to the pulmonary vasculature. With incremental exercise, the pulmonary diffusing capacity (DLCO) must increase to meet the increased oxygen demand; otherwise, a diffusion limitation may occur. The increase in DLCO with exercise is due to increased capillary blood volume (Vc) and membrane diffusing capacity (Dm). Vc and Dm increase secondary to the recruitment and distension of pulmonary capillaries, increasing the surface area for gas exchange and decreasing pulmonary vascular resistance, thereby attenuating the increase in pulmonary arterial pressure. At the same time, the recruitment of intrapulmonary arteriovenous anastomoses (IPAVA) during exercise may contribute to gas exchange impairment and/or prevent large increases in pulmonary artery pressure.
We describe two techniques to evaluate pulmonary diffusion and circulation at rest and during exercise. The first technique uses multiple-fraction of inspired oxygen (FIO2) DLCO breath holds to determine Vc and Dm at rest and during exercise. Additionally, echocardiography with intravenous agitated saline contrast is used to assess IPAVAs recruitment.
Representative data showed that the DLCO, Vc, and Dm increased with exercise intensity. Echocardiographic data showed no IPAVA recruitment at rest, while contrast bubbles were seen in the left ventricle with exercise, suggesting exercise-induced IPAVA recruitment.
The evaluation of pulmonary capillary blood volume, membrane diffusing capacity, and IPAVA recruitment using echocardiographic methods is useful to characterize the ability of the lung vasculature to adapt to the stress of exercise in health as well as in diseased groups, such as those with pulmonary arterial hypertension and chronic obstructive pulmonary disease.

To assess the pulmonary diffusion and vasculature responses to exercise, we describe the multiple-inspired oxygen diffusion capacity technique to determine capillary blood volume and membrane diffusing capacity, as well as agitated saline contrast echocardiography to assess the recruitment of intrapulmonary arteriovenous anastomoses.

Conducting Maximal and Submaximal Endurance Exercise Testing to Measure Physiological and Biological Responses to Acute Exercise in Humans

Regular physical activity has a positive effect on human health, but the mechanisms controlling these effects remain unclear. The physiologic and biologic responses to acute exercise are predominantly influenced by the duration and intensity of the exercise regimen. As exercise is increasingly thought of as a therapeutic treatment and/or diagnostic tool, it is important that standardizable methodologies be utilized to understand the variability and to increase the reproducibility of exercise outputs and measurements of responses to such regimens. To that end, we describe two different cycling exercise regimens that yield different physiologic outputs. In a maximal exercise test, exercise intensity is continually increased with a greater workload resulting in an increasing cardiopulmonary and metabolic response (heart rate, stroke volume, ventilation, oxygen consumption and carbon dioxide production). In contrast, during endurance exercise tests, the demand is increased from that at rest, but is raised to a fixed submaximal exercise intensity resulting in a cardiopulmonary and metabolic response that typically plateaus. Along with the protocols, we provide suggestions on measuring physiologic outputs that include, but are not limited to, heart rate, slow and forced vital capacity, gas exchange metrics, and blood pressure to enable the comparison of exercise outputs between studies. Biospecimens can then be sampled to assess cellular, protein, and/or gene expression responses. Overall, this approach can be easily adapted into both short- and long-term effects of two distinct exercise regimens.

To assess the influence of exercise intensity on physiologic and biologic responses, two different exercise testing protocols were utilized. Methods outlining exercise testing on a cycle ergometer as an incremental maximal oxygen consumption test and endurance, steady state submaximal endurance test are described.

Integration of Brain Tissue Saturation Monitoring in Cardiopulmonary Exercise Testing in Patients with Heart Failure

Cerebral hypo-oxygenation during rest or exercise negatively impacts the exercise capacity of patients with heart failure with reduced ejection fraction (HF). However, in clinical cardiopulmonary exercise testing (CPET), cerebral hemodynamics is not assessed. NIRS is used to measure cerebral tissue oxygen saturation (SctO2) in the frontal lobe. This method is reliable and valid and has been utilized in several studies. SctO2 is lower during both rest and peak exercise in patients with HF than in healthy controls (66.3 &#177; 13.3% and 63.4 &#177; 13.8% vs. 73.1 &#177; 2.8% and 72 &#177; 3.2%). SctO2 at rest is significantly linearly correlated with peak VO2 (r = 0.602), oxygen uptake efficiency slope (r = 0.501), and brain natriuretic peptide (r = -0.492), all of which are recognized prognostic and disease severity markers, indicating its potential prognostic value. SctO2 is determined mainly by end-tidal CO2 pressure, mean arterial pressure, and hemoglobin in the HF population. This article demonstrates a protocol that integrates SctO2 using NIRS into incremental CPET on a calibrated bicycle ergometer.

This protocol integrated near-infrared spectroscopy into conventional cardiopulmonary exercise testing to identify the involvement of the cerebral hemodynamic response in exercise intolerance in patients with heart failure.

Providing Visual Biofeedback Using Brightness Mode Ultrasound During a Golf Swing

Using ultrasound biofeedback in conjunction with verbal cueing can increase muscle thickness more than verbal cueing alone and may augment traditional rehabilitation techniques in an athletic, physically active population. Brightness mode (B-mode) ultrasound can be applied using frame-by-frame analysis synchronized with video to understand muscle thickness changes during these dynamic tasks. Visual biofeedback with ultrasound has been established in static positions for the muscles of the lateral abdominal wall. However, by securing the transducer to the abdomen using an elastic belt and foam block, biofeedback can be applied during more specific tasks prevalent in lifetime sports, such as golf. To analyze muscle activity during a golf swing, muscle thickness changes can be compared. The thickness must increase throughout the task, indicating that the muscle is more active. This methodology allows clinicians to immediately replay ultrasound videos for patients as a visual tool to instruct proper activity of the muscles of interest. For example, ultrasound can be used to target the external and internal obliques, which play an important role in swinging a golf club or any other rotational sport or activity. This methodology aims to increase oblique muscle thickness during the golf swing. Additionally, the timing of muscle contraction can be targeted by instructing the patient to contract the abdominal muscles at specific time points, such as the beginning of the downswing, with the goal of improving muscle firing patterns during tasks.

Brightness mode ultrasound can be used to provide visual biofeedback of the muscles of the lateral abdominal wall during a golf swing. Post-swing visual and verbal instruction can increase the muscle activation and timing of the external and internal obliques.

Muscle Function Obtained with Motion Mode Ultrasound and Surface Electromyography during Core Endurance Exercise

Motion mode (M-mode) ultrasound allows researchers and clinicians to measure the change of muscle thickness across time. Muscle thickness can be measured between fascial borders at a given time point during an exercise. This selected time point produces a one-dimensional image resulting in real-time, live observation of anatomy. Ultrasound used during functional movement can be referred to as dynamic ultrasound; this is feasible and reliable with the use of a linear transducer, elastic belt, and foam block to secure consistent transducer placement. The lateral abdominal wall is commonly investigated using ultrasound due to the overlapping nature of the muscles. Surface electromyography (sEMG) can complement M-mode ultrasound imaging because it measures the electrical representation of muscle activation. There is minimal evidence using M-mode ultrasound and sEMG simultaneously during core exercise. Exercises that challenge the core musculature involve both isometric holds (e.g., side plank), as well as oscillatory extremity movements (e.g., dead bug). In this study, both instruments will be used simultaneously to measure core muscle function during exercise. Ultrasound measurements will be obtained using a linear transducer and ultrasound unit, and sEMG measurements will be acquired from a wireless sEMG system. To make comparisons between participants and exercises, normalization methods using static, exercise starting positions for both instruments will be used. An activation ratio will be used for ultrasound and calculated by dividing the contracted thickness (thickness during a time point of exercise) by the rested (starting position) thickness. Muscle thickness will be measured in centimeters from the superior inferior fascial border to inferior superior fascial border. These methods aim to offer an innovative and practical measurement of muscle function with M-mode ultrasound and sEMG during core endurance exercises.

This protocol uses motion mode ultrasound and surface electromyography simultaneously to measure muscle function of the core. Muscle thickness and activation of the local stabilizers (e.g., transverse abdominis, internal oblique) and global movers (e.g., external oblique) is achievable during specific time points of the side plank and dead bug exercises.

Bridging the Technology Divide in the COVID-19 Era: Using Virtual Outreach to Expose Middle and High School Students to Imaging Technology

Increasing the diversity of students choosing careers in science, technology, engineering, and mathematics (STEM) fields is an area of intense focus across the USA, especially in kindergarten through 12th grade (K-12)-focused pipeline programs in medical schools. A diverse STEM workforce contributes to better problem-solving and equity in health care. Two of the many major barriers for rural students are the lack of sufficient STEM role models and limited access to technology in the classroom. Medical schools often serve as an important resource for students in the local community who can easily gain access to STEM professionals and modern technology through on-campus, sponsored events and STEM outreach to the local classrooms. However, underrepresented minority (URM) students often live in socioeconomically distressed parts of rural states such as Arkansas, where access to STEM role models and technology is limited. Virtual learning in the COVID-19 era has proven that the imaging technology resources of a medical school can be harnessed to reach a wider audience, especially students living in rural areas far from the medical school campus.

This article presents an overview of how synchronous web-based virtual outreach can be used to expose 6th-12th grade students to advanced imaging technologies such as ultrasound, computerized tomography, and electroencephalography. The paper discusses the methods and equipment needed to livestream integrated educational sessions for effective student engagement in STEM.

Randomized Controlled Trial to Study the Acute Effects of Strength Exercise on Insulin Sensitivity in Obese Adults

An acute session of strength exercise (SE) ameliorates insulin sensitivity (IS) for several hours; however, the effects of SE volume (i.e., number of sets) have not been studied thoroughly. Although it is intuitive that some SE is better than none, and more is better than some for the improvement of IS, high-volume sessions might be challenging for diseased populations to complete, especially obese adults, for whom even a brisk walk can be challenging. This protocol details a randomized clinical trial to assess the acute effects of SE on IS in obese adults. The inclusion criteria are body mass index &#62;30 kg/m2, central obesity (waist circumference &#62;88 cm and &#62;102 cm for women and men, respectively), and age &#62;40 years. Participants will be familiarized with the SE (7 exercises targeting major muscle groups) and then will perform three sessions in a randomized order: session 1 - high-volume session (3 sets/exercise); session 2 - low-volume session (1 set/exercise); session 3 - control session (no exercise). Diet will be controlled the day before and on the day of the sessions. Sessions will be completed at night, and an oral glucose tolerance test will be performed the next morning, from which several indexes of IS will be derived, such as the area under the curve (AUC) of glucose and insulin, the Matsuda index, the Cederholm index, the muscle IS index, and the Gutt index. Based on pilot studies, we expect ~15% improvement in IS (insulin AUC, and Matsuda and Cederholm indexes) after the high-volume session, and ~8% improvement after the low-volume session compared to the control session. This study will benefit individuals who find high-volume SE sessions challenging but still aim to improve their IS by investing 1/3 of their time and effort.
