High return to sport rate and few re-ruptures at long term in professional footballers after anterior cruciate ligament reconstruction with hamstrings
Bonanzinga T, Grassi A, Altomare D, Lucidi GA, Macchiarola L, Zaffagnini S, Marcacci M
This retrospective study in 28 professional footballers that underwent 33 ACL reconstructions using hamstring tendons graft and an over the top technique, found that the first official match was played after an average of 8.0 ± 3.6 (4.6-18.2) months in 31 cases (94%), 3 (9%) of the 33 ACL reconstruction failed, other procedures, mainly arthroscopic meniscectomies, were performed in 10 cases (30%). and the average Lysholm score at long-term evaluation after 12.6 ± 3.3 years (6.7-17.5) was 94.2 ± 8.3.
Relationships between Fitness Status and Blood Biomarkers in Professional Soccer Players
Silva AF, González-Fernández FT, Ceylan HI, Silva R, Younesi S, Chen YS, Badicu G, Wolański P, Murawska-Ciałowicz E, Clemente FM
This study in 25 professional male soccer players at baseline and after preseason found increases in platelets, creatinine, alkaline phosphatase, C-Reactive Protein, cortisol, and testosterone, whereas significant decreases were found for albumin, and calcium. Negative correlations were found between albumin, CRP and the 5-meter linear sprint split, and positive correlations were found between VAMEVAL and hemoglobin. The overall physical fitness measures improved after the preseason and significant variations (decreases/increases) were observed for the case of biochemical and hematological outcomes.
Prevalence and burden of health problems in top-level football referees
Moen C, Andersen TE, Clarsen B, Madsen-Kaarød G, Dalen-Lorentsen T
This prospective cohort study in 55 Norwegian male and female top-level referees during the 2020 competitive season found 11 injuries per 1000 match hours, and 1.4 illnesses per referee-year. Injuries to the lower legs and feet represented the highest burden of health problems. Female referees reported more health problems than male referees, and on-field referees reported more health problems than assistant referees. Gradual-onset injuries were most prevalent and caused the greatest absence from training and matches.
