Use of Lifesaving Medications by Athletic Trainers.

The athletic trainer's (AT's) emergency management skillset requires competency in the delivery of basic lifesaving medications. Some lifesaving medications have been a part of athletic training practice for decades, but that list has grown as ATs' practice settings have expanded, increasing the types of emergent conditions that the AT may have to treat. The 2020 Commission on Accreditation of Athletic Training Education (CAATE) curricular standards require that athletic training students be trained to administer the following: supplemental oxygen, nitroglycerine, low-dose aspirin, bronchodilators, epinephrine using an automated injection device, glucagon, and naloxone.

Explosive Quadriceps Strength Symmetry and Landing Mechanics Limb Symmetry After Anterior Cruciate Ligament Reconstruction in Females.

Context: Emerging evidence suggests that a lower quadriceps rate of torque development (RTD) after anterior cruciate ligament (ACL) reconstruction (ACLR) may be associated with altered landing mechanics. However, the influence of quadriceps RTD magnitude and limb symmetry on landing mechanics limb symmetry remains unknown.

Objective: To assess the influence of quadriceps RTD magnitude and limb symmetry on limb symmetry in sagittal-plane landing mechanics during functional landing tasks in females with or without ACLR.

A biomechanical comparison of dominant and non-dominant limbs during a side-step cutting task.

Numerous studies have investigated anterior cruciate ligament (ACL) injury risk by examining gender differences in knee and hip biomechanics during a side-step cutting manoeuvre since it is known that ACL injury often occurs during such a task. Recent investigations have also examined lower extremity (LE) biomechanics during side-step cutting in individuals following ACL reconstruction (ACLR). Common research practice is to compare knee and hip biomechanics of the dominant limb between groups but this can add considerable complexity for clinicians and researchers.

Athletic Training and Public Health Summit.

Objective: To introduce athletic trainers to the benefits of using a population-based approach to injury and illness prevention and to explore opportunities for partnering with public health professionals on these initiatives.

Background: Athletic trainers play leading roles in individual injury and illness prevention but are less familiar with policy development, evaluation, and implementation from a population-level standpoint. The Athletic Training and Public Health Summit was convened to understand, explore, and develop the intersection of athletic training and public health.

Relationships between explosive and maximal triple extensor muscle performance and vertical jump height.

The purpose of this study was to examine the relationships between maximum vertical jump height and (a) rate of torque development (RTD) calculated during 2 time intervals, 0-50 milliseconds (RTD50) and 0-200 milliseconds (RTD200) after torque onset and (b) peak torque (PT) for each of the triple extensor muscle groups. Thirty recreationally active individuals performed maximal isometric voluntary contractions (MVIC) of the hip, knee and ankle extensors, and a countermovement vertical jump. Rate of torque development was calculated from 0 to 50 (RTD50) and 0 to 200 (RTD200) milliseconds after the onset of joint torque.

Spectral properties of H-reflex recordings after an acute bout of whole-body vibration.

Although research supports the use of whole-body vibration (WBV) to improve neuromuscular performance, the mechanisms for these improvements remain unclear. The purpose of this study was to identify the effect of WBV on the spectral properties of electrically evoked H-reflex recordings in the soleus (SOL) muscle. The H-reflex recordings were measured in the SOL muscle of 20 participants before and after a bout of WBV.
