“…Warm-up prior to the start of physical activities is commonplace and lauded by health professionals,1 coaches and landmark texts2 3 for its potential for both performance enhancement and injury prevention. The exact mechanisms and outcomes of various warm-up modes, however, are still unclear.…”

“…The exact mechanisms and outcomes of various warm-up modes, however, are still unclear. A term with broad connotations, warm-up is defined simply by Brukner and Khan2 as being activity that “prepares the body for exercise.” There is some disagreement in major sports medical texts regarding acceptable modes of these preparatory activities, especially with regard to whether static stretching is a warm-up activity 2 3. For this review, we took a broad view of warm-up modes and defined warm-up as a “protocol specifically undertaken to prepare for the onset of subsequent physical activity.”…”

“…Considering the different injury mechanisms of common sites of upper and lower extremity injury3 4 and differing motor pathways to upper and lower body performance, warm-up effects on the upper extremity need focused investigation. We conducted a systematic review to address questions regarding the optimum upper body warm-up modes for (1) performance enhancement and their physiological correlates across strength, power, endurance, flexibility and accuracy outcomes and (2) injury prevention.…”

A systematic review of the effects of upper body warm-up on performance and injury

Purpose This systematic review was conducted to identify the impact of upper body warm-up on performance and injury prevention outcomes. Methods Web of Science, MEDLINE, SPORTDiscus, PsycINFO and Cochrane databases were searched using terms related to upper extremity warm-up. Inclusion criteria were English language randomised controlled trials from peer-reviewed journals in which investigation of upper body warm-up on performance and injury prevention outcomes was a primary aim. Included studies were assessed for methodological quality using the PEDro scale. A wide variety of warm-up modes and outcomes precluded meta-analysis except for one group of studies. The majority of warm-ups were assessed as having 'positive', 'neutral', 'negative' or 'specific' effects on outcomes. Results Thirty-one studies met the inclusion criteria with 21 rated as having 'good' methodological quality. The studies investigated a total of 25 warm-up modes and 43 outcome factors that could be grouped into eight mode and performance outcome categories. No studies of upper body warm-up effects on injury prevention were discovered. Conclusions Strong research-based evidence was found for the following: high-load dynamic warm-ups enhance power and strength performance; warm-up swings with a standard weight baseball bat are most effective for enhancing bat speed; short-duration static stretching warm-up has no effect on power outcomes; and passive heating/cooling is a largely ineffective warmup mode. A clear knowledge gap in upper body warmup literature is the lack of investigation of injury prevention outcomes.

“…As De Lee and Drez3 state in their text, ‘“Sidelines” are the front lines of sports medicine, especially in contact and collision sports’. Part of this study included a review of literature specimens from primary care sports medicine, orthopaedic sports medicine and wilderness medicine event coverage 3–7. Team physicians in the mass event, high school, collegiate and professional sporting arenas claiming association in the AMSSM or AOSSM have not previously been solicited by an online survey to document the usage of items typically found ‘highly desirable’ in a team physician's main ‘medical bag’ 2.…”

Three major duties of the team physician, according to a consensus statement published in 2001, are ‘to plan and train for emergencies during competition and practice, address equipment and supply issues and provide for proper event coverage’. Various medical supplies have been consistently recommended in articles preceding and following the consensus statement while others have not. Nonetheless, there has never been an online survey of team physicians involved with the American Medical Society for Sports Medicine or the American Orthopaedic Society for Sports Medicine covering community, high school, collegiate and professional sporting events that documented the usage of supplies typically found in a team physician's main ‘medical bag’ by consensus standards. The purpose of this study was to document the usage frequencies of supplies listed as ‘highly desirable for the “medical bag” to include’ as well as stocking, storage and inventory maintenance protocols for these events and to compare them with recommendations from the consensus statement as well as some protocols involving prehospital care from a ‘wilderness’ perspective.

Anterior cruciate ligament (ACL) reconstruction reestablishes electromyographic activity during moderate activities such as walking but is unclear if this is also the case in sports activities such as high intensity running that results in accumulation of metabolic fatigue. Nine bone-patella tendon-bone ACL reconstructed athletes were evaluated 19.2 (5.7) months post-operatively using a telemetric electromyographic system. The neuromuscular response of vastus lateralis and biceps femoris muscles was tested bilaterally on separate occasions during 10 min running at moderate intensity (20% below the lactate threshold) and 10 min running at high intensity (40% above the lactate threshold). During moderate intensity running, electromyographic activity did not change for either leg. During high intensity running, electromyographic activity did not change for the vastus lateralis of the ACL reconstructed leg [267.8 (142.8)-263.8 (128.9) microV, P > 0.05] while it increased significantly [294.2 (120.6)-317.1 (140.5) microV, P = 0.03] for the vastus lateralis of the intact leg. High intensity exercise that is associated with accumulation of metabolic fatigue, results in an impaired neuromuscular response for the vastus lateralis muscle of the ACL reconstructed leg.
