The Benefits of Sport and Exercise for Donor Kidney Recipients Тatiana Yu. Shelekhova MD,PhD,* Maksim M. Kuranov,* Sergey V. Tsvetkov,* Irina A. Lazareva MD, PhD,* and Olga M. Tsirulnikova MD, PhD*,† Affiliations: Sechenov First Moscow State Medical University (Sechenov University), Moscow, Russia; and †Shumakov National Medical Research Center of Transplantology and Artificial Organs Moscow, Russia. Objective: To study physical activity and cardiovascular disease (CVD) risk factors in donor kidney recipients. Study Design: Evidence-based medicine. Descriptive studies. Subjects: Seventy adult donor kidney recipients (not on dialysis) with satisfactory graft function. Intervention: Physical activity was assessed using a pedometer and the International Questionnaire on Physical Activity (IPAQ). Risk factors for CVD were identified using a questionnaire developed by the researchers. Outcome Measures: On the day of the competition, physical activity, quality of life, and a questionnaire to identify CVD risk factors were assessed. The study included 70 adult kidney donor recipients who participated in sports competitions in running and swimming in June 2024. The study population included 41 men and 29 women (patients underwent transplantation between 2004 and 2023). The mean age of the patients was 43.5 ± 10.3 years (maximum, 64 years; minimum, 20 years). At the time of the competition, the minimum time since kidney transplantation was 6 months, and the maximum was 19 years. Results: According to the survey results, 23 participants (32.85%) lead an active lifestyle, 32 participants (45.7%) lead a moderately active lifestyle, 7 participants (10%) lead a sedentary lifestyle, and 8 participants (11.4%) lead a sedentary lifestyle. Patients with active and moderately active lifestyles were grouped into Group I, and those with inactive and sedentary lifestyles were grouped into group II. Group I showed a reduced incidence of arterial hypertension (by 17.7%), obesity (by 11.5%), overweight (by 12.2%), and underweight (by 9.7%) compared to group II. Sports history showed that 37 participants were involved in sports (53.85%), with 10 participants practicing sports before and after transplantation (14.3%). Seven participants had formal sports achievements (10%). Ten participants were actively engaged in sports activities such as sports games, swimming, running, tennis, and martial arts (14.3%). According to IPAQ testing, hypodynamia was observed in 7 participants from Group II (46.7%). Conclusions: Exercise and sports serve as a preventive measure against various comorbidities and complications to which kidney transplant patients are prone. All donor kidney recipients can be recommended to engage in physical training and sports to prevent the development of CVD risks. Lower Extremity Weakness and Injury Risk in High-Level Football Players Jordan Buchko, MD,* Bruce Craven, MSc,† Kirat Shukla, PhD, MSc,‡ Hayley Legg, PhD,† Mikayla Rudniski, BSc Hons,§ Janan Ashique, BSc,§ Thomas Goldade, BSc Hons,§ Mason Beaulieu, BSc Hons,§ Davidson Fadare, BSc,§ Samuel Girgis, BSc,§ Elliot Grande-Sherbert, BAS,§ and Ben Verrall, BSc§ Affiliations: *Division of Orthopedic Surgery, Department of Surgery, University of Saskatchewan, Saskatoon, SK, Canada; †Craven SPORT Services, Saskatoon, SK, Canada; ‡Research Department, Saskatchewan Health Authority, Regina, SK, Canada; and §College of Medicine, University of Saskatchewan, Saskatoon, SK, Canada. Objective: To investigate whether hip abductor strength deficits and asymmetry are associated with a higher incidence of in-season lower extremity injuries in high-level football players. Study Design: Prospective cohort study. Subjects: 319 participants from 4 high-level post-secondary football teams: 2 U Sports Canadian university teams (n = 70 and n = 86) and 2 Canadian Junior Football League (CJFL) teams (n = 71 and n = 92). Observation Technique: Participants underwent preseason and mid-season assessments, which included countermovement jump (CMJ) testing on dual force plates, and isometric hip abduction strength measurements using handheld dynamometers. Injuries sustained throughout the season were documented by team therapists. Outcome Measures: The primary outcomes included hip abductor strength and asymmetry, both assessed during pre-season and mid-season testing, and the incidence of lower extremity injuries recorded throughout the season. Results: Data from the CJFL teams (n = 141; 35 documented injuries) revealed no significant association between muscle strength metrics and injury occurrence. A prior history of lower extremity injury demonstrated a potential trend toward increased injury risk but did not reach statistical significance (P = 0.10). Conclusion: Preliminary analysis suggests that isometric muscle strength alone does not significantly predict injury occurrence. However, our initial analysis is limited by a small sample size and narrow assessment of variables due to active data collection. Further analyses plans to incorporate a larger sample size including data from the U Sports teams, and will account for additional factors such as distinguishing contact and non-contact injuries, and body mass index once available. We hypothesize that impaired hip abductor strength will show a stronger association with non-contact lower extremity injuries during the in-season period. If a significant relationship is established, these findings can be used to identify and counsel athletes at increased risk, as well as develop targeted strengthening programs to reduce injury risk. The Relationship Between Repeat Sprint Ability and Sport-Specific Skills in Elite Youth Soccer Players Timur M. Vakhidov, Elizaveta S. Kapralova, MD, Georgiy I. Malyakin, MD, Anton Yu. Emanov, Mikhail A. Vinogradov, PhD, Vyacheslav P. Kolesnichenko, Sabina Garipova, BSc, Ryland Morgans, PhD and Eduard N. Bezuglov, MD, PhD Affiliation: High Performance Sports Laboratory, Sechenov First Moscow State Medical University, Moscow, Russia. Objective: To investigate the relationship between repeat sprint ability (RSA) and sport-specific skills in elite youth soccer players. Study Design: Cross-sectional. Subjects: Sixty-seven elite youth soccer players (age: 16.3 ± 0.8 years, weight: 69.0 ± 8.7 kg, height: 179.4 ± 8.3 cm, BMI: 21.3 ± 1.4 kg/m2). Observation Technique: The test battery assessed speed and strength (30-m sprint, countermovement jump), sport-specific skills (change of direction (COD), agility t test, dribbling), and anaerobic endurance (RSA) using the 6 x 20/20 protocol: 6 20-meter sprints with 20 seconds of passive rest. Outcome Measures: Mean time across all RSA test sprints (RSAmean) and fatigue indices caused by repeated sprints, such as the fatigue index (FI) and percentage decrement score (Sdec), were analyzed. A correlation was considered strong if it was between 0.70 and 1.00, moderate if it was between 0.30 and 0.69, and weak if it was between 0.01 and 0.29. The Shapiro-Wilk test was used to assess the normality of distribution. Pearson's or Spearman's correlation tests were used to determine the relationships between the analyzed parameters. The test results were obtained using a SmartSpeed Pro timing system (VALD Performance, Australia). Results: RSAmean showed a moderate positive correlation with COD performance (rs = 0.589, P < 0.001) and dribbling skills (rs = 0.507, P < 0.001), and a strong positive correlation with agility t test time (rs = 0.764, P < 0.001). No significant correlations were found between FI or Sdec and sport-specific skills. Conclusions: A significant positive relationship was found between the mean time of RSA test sprints and the performance in dribbling, change of direction, and agility t test in elite youth soccer players. Practitioners should consider these findings when designing training programs aimed at developing sport-specific skills.
