Competition Between Desired Competitive Result, Tolerable Homeostatic Disturbance, and Psychophysiological Interpretation Determines Pacing Strategy.

Scientific interest in pacing goes back >100 years. Contemporary interest, both as a feature of athletic competition and as a window into understanding fatigue, goes back >30 years. Pacing represents the pattern of energy use designed to produce a competitive result while managing fatigue of different origins.

Innovation in Learning: Critical Review of the Literature Is Absolutely Necessary for the Modern Medical Student.

The concept of a journal club has been around for decades and is a useful tool to help teach residents about evidence-based medicine. Although some students may be exposed to the concept during their third or fourth year of medical school, many do not have exposure to this until their residency. This innovation report describes a program to help introduce first and second-year medical students to a team-based approach to journal clubs so that they can apply principles of evidence-based practice early on in their medical school training.

The Management of Anxiety and Depression in Pediatrics.

Anxiety and depression are among the most common psychiatric conditions affecting children and adolescents, and physicians in primary care settings often represent the first point of contact for these patients. Therefore, it is critical to provide these clinicians with an overview of current, evidence-based approaches for treating these conditions in pediatric and adolescent patients. Cognitive behavioral therapy (CBT) is an appropriate and effective first-line intervention for anxiety disorders in children and adolescents.

Objective: To compare the attenuation of the medial coronoid process (MCP) in dogs with and without arthroscopically confirmed evidence of medial coronoid disease (MCD).

Animals: The database at our institution was searched for cases with thoracic limb lameness, diagnosed with MCD by arthroscopic examination that had CT as part of their investigation and compared with a control group of elbow joints from cadavers euthanized for reasons unrelated to MCD. A total of 84 elbow joints were included that met these criteria.

The performance during four stationary knife attacks: Implications for tactical training.

Unlabelled: With over 72,000 offenses between 2010 and 2020 in the USA, knives were the third most commonly used weapon in all violent crimes between behind personal weapons and handguns.

Purpose: Examine the performance of different stab (Thrust and overhead) and slash (Figure 8 and Reverse) knife motions to determine how long it takes to execute each motion. In addition, examine the variability in executing each motion to inform future self-defense strategies.

Optimization of the Critical Speed Concept for Tactical Professionals: A Brief Review.

Tactical professionals often depend on their physical ability and fitness to perform and complete occupational tasks to successfully provide public services or survive on the battlefield. Critical speed (CS), or maximal aerobic steady-state, is a purported measure that predicts performance, prescribes exercise, and detects training adaptions with application to tactical professionals. The CS concept has the versatility to adapt to training with load carriage as an integrated bioenergetic system approach for assessment.

Predictors of Work Efficiency in Structural Firefighters.

Objective: Develop a novel work efficiency (WE) metric to quantify firefighter physical ability and identify correlates of WE.

Methods: Physical fitness and anthropometric measurements were taken on 19 male firefighters. Firefighters performed a timed maximal effort simulated fireground test (SFGT).

Prevalence of mineralisation of the tendon of the supraspinatus muscle in non-lame dogs.

Objectives: Mineralisation of the tendon of the supraspinatus muscle has been reported as a common finding in dogs with thoracic limb lameness. It is not clear if the mineralisation is a clinically significant cause, or a secondary effect, of lameness. The aim of this retrospective study was to determine the prevalence of mineralisation of the tendon of the supraspinatus muscle in dogs presented to the clinic for reasons other than lameness and where lameness was not evident at the time of presentation.

Predicting Maximal Oxygen Uptake Using the 3-Minute All-Out Test in High-Intensity Functional Training Athletes.

Maximal oxygen uptake (VO) and critical speed (CS) are key fatigue-related measurements that demonstrate a relationship to one another and are indicative of athletic endurance performance. This is especially true for those that participate in competitive fitness events. However, the accessibility to a metabolic analyzer to accurately measure VO is expensive and time intensive, whereas CS may be measured in the field using a 3 min all-out test (3MT).

Increased velocity at VOmax and load carriage performance in army ROTC cadets: prescription using the critical velocity concept.

The purpose of this study was to evaluate the effects of using the critical velocity (CV) concept to prescribe two separate high-intensity interval training (HIT) exercise programs aimed at enhancing CV and load carriage performance. 20 young adult participants (male = 15, female = 5) underwent a 4-week training period where they exercised 2 dwk. Participants were randomly assigned into two groups: (1) HIT or (2) Load Carriage-HIT (LCHIT).
