February 2020 Sports Medicine Journal Roundup


  • Higher number of pain sites throughout the body was a consistent predictor of poor outcome and less change at 1 year.

  • Baseline levels for anterior knee pain scale and worst pain predicted respective final scores and change scores.

  • This study indicated that the proximally longer fifth metatarsal may cause greater stress at the base of the fifth metatarsal bone because the lever arm becomes long.

  • In addition, high medial longitudinal arch may contribute to increased load on the lateral side of the foot.

  • Large/massive tear size, lower Veterans RAND 12-Item Health Survey mental component score, and several additional patient and disease-specific factors are associated with baseline PROMs in patients undergoing rotator cuff repair.

  • The injury risk was higher in participants running in the hard shoes compared with those using the soft shoes.

  • However, the relative protective effect of greater shoe cushioning was found only in lighter runners


  • 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.

  • 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.

  • PPE according to the Italian model identified a range of diseases in 2.0% of apparently healthy athletes at an average cost of €79


  • 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.

  • The use of PA breaks during sitting moderately attenuated post-prandial glucose, insulin, and TAG, with greater glycaemic attenuation in people with higher BMI.

  • Foam rolling represents an effective method to induce acute improvements in joint ROM


  • 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).
