Tuakli-Wosornu YA, Sun Q, Gentry M, et al. Non-accidental harms (‘abuse’) in athletes with impairment (‘para athletes’): a state-of-the-art review. British Journal of Sports Medicine 2020;54:129-138.

  • Bullying in young, visually impaired athletes is described most commonly in the available literature.

  • Due to the limited amount of data, the prevalence of non-accidental harms in Para athletes remains unclear and information on trends over time is similarly unavailable.

Steffen K, Soligard T, Mountjoy M, et al. How do the new Olympic sports compare with the traditional Olympic sports? Injury and illness at the 2018 Youth Olympic Summer Games in Buenos Aires, Argentina. British Journal of Sports Medicine 2020;54:168-175.

  • The overall injury incidence of 15.5 injuries per 100 athletes was higher, while the overall illness incidence of 8.4 illnesses per 100 athletes was similar to previous youth and Olympic Games.

  • The new sports did not differ significantly compared with the other sports with respect to injury and illness risk.

González-Mohíno F, Santos-Concejero J, Yustres I, González-Ravé JM. The Effects of Interval and Continuous Training on the Oxygen Cost of Running in Recreational Runners: A Systematic Review and Meta-analysis. Sports Med. 2020 Feb;50(2):283-294. doi: 10.1007/s40279-019-01201-x. Review. PubMed PMID: 31606879.

  • Continuous training seems, overall, a better strategy than interval training to reduce the oxygen cost in recreational endurance runners.

  • However, oxygen cost reductions are influenced by several variables including the duration of the program, runners’ aerobic capacity, the intervals duration and the volume of interval training per week.

Loh R, Stamatakis E, Folkerts D, Allgrove JE, Moir HJ. Effects of Interrupting Prolonged Sitting with Physical Activity Breaks on Blood Glucose, Insulin and Triacylglycerol Measures: A Systematic Review and Meta-analysis.

Hanlon, C., Krzak, J. J., et al. Effect of Injury Prevention Programs on Lower Extremity Performance in Youth Athletes: A Systematic Review. Sports Health, 12(1), 12–22. https://doi.org/10.1177/1941738119861117

  • Among studies, the mean percentage of improvement identified was 11.3% for force generation, 5.7% for coordination, 5.2% for posture, and 5.2% for balance.

  • The lowest mean percentage improvement was in speed (2.2%).

  • Endurance was not significantly affected by any of the programs.

  • Specialization and exceeding 8 months per year in a single sport was associated with overuse injury in volleyball, which is one of the most popular youth sports for female athletes.

  • Specialization was not associated with overuse injury in basketball or soccer athletes.

  • Female basketball athletes were nearly 4 times more likely to report a history of overuse injury compared with male basketball athletes.

  • The sex of a youth athlete and the sport that he or she plays may influence the risk of overuse injury associated with sport specialization.

  • Of the contacted offices that provided information on both platelet rich plasma (PRP) and stem cell (SC) availability (n = 1325), 268 (20.2%) offered both treatments, 550 (41.5%) offered only PRP injections, 20 (1.5%) offered only SC injections, and 487 (36.8%) did not offer either treatment.

  • The mean ± SD cost of a PRP injection was $707 ± $388 (range, $175-$4973), and the mean cost of an SC injection was $2728 ± $1584 (range, $300-$12,000).

  • Practices that offered PRP injections were located in areas with higher median household income (P = 0.047). Variables associated with higher cost of PRP injections included city population (P < 0.001) and median income of residents (P < 0.001).
