August 2021 Sports Medicine Journal Roundup

JULY 2021 JOURNAL ROUNDUP

This month, we review all of August’s Sports Medicine Journals all in one place here on the sports medicine review.

The American Journal of Sports Medicine (August 2021)

  • BTB and soft tissue autografts had a decreased risk in graft rerupture compared with BTB allografts. BTB autografts were associated with higher activity level than were BTB allografts at 6 years after revision reconstruction.
  • Surgeons and patients should consider this information when choosing a graft for revision ACL reconstruction.
  • Early weightbearing after the operative treatment of an unstable ankle fracture was not inferior to nonweightbearing in terms of OMAS assessed at 12 months after injury.
  • The patients’ subjective satisfaction was similar between the groups, although the time taken to return to preinjury activities was shorter in the early weightbearing group.
  • Combined blood flow restriction-low-intensity exercise (BFR-LIX) may yield greater increases in shoulder and arm lean mass, strength, and muscular endurance compared with fatiguing LIX alone during rotator cuff exercises.
  • These findings may be due, in part, to a greater activation of shoulder muscles while using BFR.
  • The 45° flexion AP view can detect capitellum OCD with excellent accuracy, a high level of confidence, and substantial interobserver agreement.
  • When added to standard AP and lateral radiographs, the 45° flexion AP view aids in the identification of capitellum OCD.
  • Short-term strength training can improve sequelae symptoms and optimize muscle function even many years after a strain injury, but it does not seem to influence the overall structural abnormalities of the area with scar tissue.
  • Scapular dyskinesis was not significantly associated with the development of shoulder injury in athletes.

British Journal of Sports Medicine (August 2021)

  • The authors contend that the physiologic equivalent temperature (PET) is a better predictor of collapses during a half marathon than the WBGT.
  • They call for further investigation of PET as a screening tool alongside WBGT.
  • Helmets styled for skateboarding are available ‘off the shelf’ that will offer protection to the head against skull fractures and intracranial injuries in competitive skateboarding.
  • There is an urgent need to commence a program of research and development to understanding and control head injury risks.
  • In comparison to climbing on real rock, artificial climbing walls have recently been associated with higher injury rates. Finger injuries such as tenosynovitis, pulley lesions and growth plate injuries are the most common injuries.
  • As finger injuries are sport-specific, medical supervision of climbing athletes requires specific medical knowledge for diagnosis and treatment.
  • Recommendations are based on current evidence and consensus and aligned with international lower back pain (LBP) guidelines in non-athletic populations, but with advice aimed specifically at rowers.
  • The authors recommend that research in relation to all aspects of prevention and management of LBP in rowers be intensified.
  • Health wearable devices are effective intervention tools/strategies for reducing body weight and BMI in individuals with overweight/obesity and chronic comorbidities.
  • Health education through sport, using the ‘11 for Health’ model, was enjoyable for girls and boys aged 10–12 years old, and improved health knowledge related to hygiene, nutrition, physical activity and well-being.

Sports Medicine (August 2021)

  • This article provides an overview of the available scientific data describing the impact of movement tempo on hypertrophy and strength development with a thorough analysis of changes in duration of particular phases of movement.
  • Additionally, the review provides movement tempo-specific recommendations as well real training solutions for strength and conditioning coaches and athletes, depending on their goals.
  • Regular, moderate to vigorous physical activity is associated with reduced risk of community-acquired infectious diseases and infectious disease mortality, enhances the first line of defense of the immune system, and increases the potency of vaccination.
  • Performing physical activity (PA) during Covid-19 is associated with less depression and anxiety.
  • To maintain PA routines during Covid-19, specific volitional and motivational skills might be paramount to overcome Covid-19 specific barriers.
  • Particularly, web-based technologies could be an accessible way to increase motivation and volition for PA and maintain daily PA routines.

Sports Health Journal (July/August 2021)

  • We found no significant improvement in soccer-related performance with caffeine compared with placebo or no intervention.
  • However, caffeine appears to be safe.
  • The repetitions-to-failure test is a valid method of predicting the 1RM during the concentric-only and touch-and-go bench press variants.
  • However, the accuracy of the prediction could be compromised with weaker and less experienced individuals and if more than 10 repetitions are completed during the repetitions-to-failure test.
  • BPPV is fairly common in pediatric concussion, occurring in one-third of the patients studied.
  • BPPV is often not diagnosed and treated until many weeks after the injury.
  • Increased awareness of the evaluation and management of BPPV among pediatric concussion providers may help expedite resolution of dizziness and hasten overall recovery in affected patients.
  • Fasciotomy is an effective treatment of CECS, with this study identifying certain patient variables leading to greater functional improvement.
  • Multiple linear regression analysis revealed deep posterior compartment involvement, younger age, a history of depression, and male sex to be significant independent predictors of enhanced improvement after fasciotomy.

Current Sports Medicine Reports (August 2021)​

  • There is a growing awareness that COVID-19 can cause sustained morbidity in some patients, and physical training and rehabilitation (tertiary prevention level) can be directed toward improvement in physical fitness, quality of life, and immune health.
