Introduction: In recent decades, there has been an increase in the incidence of noncontact anterior cruciate ligament (ACL) injuries during sports, leading to high costs for athletes, sports teams, ...and the healthcare system. Participants followed an individualised testing order in Session 1, and a 1-minute rest period was provided between landing tasks. The reliability of single-leg and double-leg drop jump landing tasks was determined using intraclass correlation coefficient (ICC) with 95% confidence interval (CI) values.

La incorporación del trabajo con tecnología isoinercial en los diferentes programas de entrenamiento ha contribuido a una notable mejora en el desarrollo de la fuerza y potencia muscular. Objetivos: ...evaluar la fuerza de la musculatura flexora y extensora de la rodilla en fase concéntrica y excéntrica. Método: durante 4 semanas (3 sesiones semanales) se ha realizado un programa de entrenamiento con tecnología isoinercial con movimientos simultáneos de flexión y extensión de rodilla de ambas extremidades. Antes y después del programa de entrenamiento se ha evaluado la potencia del tren inferior a través de la tecnología isoinercial versapulley en ejecuciones separadas de extensión y flexión de rodilla. Se ha obtenido y monitorizado datos de potencia, velocidad, fuerza, trabajo, tiempos de repeticiones,.., tanto en fase concéntrica como excéntrica. Resultados: se ha obtenido mejoras significativas (p<0,05) tanto en fase concéntrica como excéntrica en movimientos de flexión y extensión de la rodilla. Conclusiones: durante las primeras etapas de la recuperación funcional los ejercicios generales provocan adaptaciones entre extremidades y disminuyen la asimetría provocada por la lesión deportiva. En un proceso de recuperación física disminuye la carga excesiva que provoca trabajar la extremidad por separado y en consecuencia disminuir el periodo de recuperación. Abstrac: Training programmes incorporating isoinertial technology have contributed to a considerable improvement in developing muscle force and muscle power. Objectives: to evaluate knee flexor and extensor muscle force in concentric and eccentric contractions. Method: A 4-week training programme (3 sessions/week) using isoinertial technology was implemented, involving simultaneous flexion and extension of both knees. Before and after the training programme, lower-body power was evaluated using “VersaPulley” isoinertial technology in separate knee extension and flexion exercises. Data for power, velocity, force, work, repetition times etc. were recorded and monitored for both concentric and eccentric contractions. Results: Significant improvement (p=0.05) was recorded for both concentric and eccentric contractions in knee flexion and extension. Conclusions: In the early stages of functional recovery, general exercise enhances adaptation between limbs, reducing the asymmetry prompted by sports injuries. In the course of physical recovery, the overload caused by working separately with the affected limb is diminished, thus shortening recovery time.
Abstract
Introduction
Sleep is essential to musculoskeletal recovery, acquisition of new skills and emotional regulation in athletes. Insufficient sleep is detrimental to performance. Recent ...publications indicate that sleep duration is related to risk for injury in young athletes. We aimed at analyzing the relation between sleep opportunity and duration and the likelihood of an injury among adult elite athletes.
Methods
We studied 7,237 nights recorded with the Sleeprate application by 71 adult elite athletes from diverse sports, during the period September 2018-October 2019. Night recordings included perceived and measured sleep parameters. In addition, athletes reported their previous day nap duration, injuries and illness status. Out of the total number of nights, 4,205 included reported injury status with no injury and no illness for the previous night. Nightly total time in bed (TIB), TIB including reported naps (TIB24hr) and measured total sleep time (TST) were examined.
Results
Average TIB was significantly shorter (508±77 minutes, mean±STD) in healthy days preceding injuries than in healthy days preceding days with no injury (525±70 minutes, p<.001). Similar results were found when comparing the TIB24hr (injury: 517±83 minutes, no injury: 543±76 minutes, p<.001) and TST (injury: 443±72 minutes, no injury: 457±69 minutes, p<.001).
Conclusion
Average sleep opportunities of the elite athletes in this study were in accordance with their age and workouts load. The time athletes allow themselves as an opportunity for sleep is inversely correlated to the chances of developing an injury. These findings corroborate published research regarding sleep duration and risk of injury in athletes, yet our findings are based on real life data of elite athletes, and demonstrate the importance of sleep as part of the elite or professional athlete’s routine, suggesting that even as little as around 20 minutes of added sleep may be efficient in preventing injury.

INTRODUCTION: Tibial plateau fractures occur when the proximal tibia bears an excessive axial load and commonly occur in road Traffic accidents and sports injuries. It constitutes 1% of all ...orthopedic fractures and 8% of fractures in the elderly. The treatment of tibial plateau fractures is continuously evolving. Various techniques have emerged over the last few decades. Many people have studied these fractures and their management modalities and no single consensus has been reached regarding the superiority of any modality. MATERIALS AND METHODS: Following institutional scientific and ethical committee approval, this study was undertaken in the patients with proximal tibia fractures (Shatzker's type V and VI) reporting to the Department of Orthopedics at Apollo Hospital Bannerghatta Road, Bengaluru during the study period. This was a prospective observational study. A total of 30 consecutive patients were followed up as per the inclusion criteria. They were followed up for 6 months. RESULTS: There were a total of 30 cases of proximal tibia Shatzker type V and VI fractures followed up during the study period. The demographics constituted 73.33% males and 26.67% females with an age range of 23-64 years and a mean age of 41.66 years. The most common mode of injury was road traffic accidents amounting to 73.33% of fractures. The majority of patients were in the age group less than 40 years and men were involved more than women. The functional outcome measured via the Modified Rasmussen Score showed good to excellent results in 93.33% of cases in the postop period at 6 months. CONCLUSION: This study shows fixation with dual anatomical locking plate and screws for proximal tibia Shatzker type V and VI fractures gives good to excellent functional outcomes in the early postop period.
Methods: Cross-sectional, retrospective data on respondent characteristics, breast injuries and protective equipment, and breast pain and sports bras were collected using anonymous online surveys. ...Mann-Whitney U-tests and Chi-Squared Test of Homogeneity were performed to assess the differences in respondent characteristics between athletes who did and did not report previous breast injuries and breast pain. Only 14% reported having any breast pain management strategies.
