This study analyses the anthropometric characteristics of young Senegalese handball players (U18 and U20 categories) in order to determine the extent to which their morphological profile is compatible with the demands of high-level handball. Based on measurements of height, weight, body mass index (BMI), wingspan and hand span, the data collected from a representative sample were compared with data from young international handball players who participated in the 10thWorld Youth Handball Championship (U19) in Croatia in 2023. The results show that while the height and wingspan of Senegalese players are broadly in line with African and European benchmarks, their weight, BMI and hand span are lower. The study concludes that a morpho-functional approach is needed in the detection and training of young handball players.

Both recreational and competitive sports are experiencing growing developments. The traumas related to their practice remain unknown, thus causing a loss of abilities or a definitive stop. It is in this context that the objective of this work is to study the interest of a reathletization program following an anterior cruciate ligament reconstruction of the knee in a young footballer from Dakar Sacré Cœur. We first measured the footballer’s thigh circumference. Then we made him undergo Vameval, Crossover hop and Counter movement jump tests to determine respectively his aerobic endurance, the symmetry of the lower limb and his vertical relaxation. Finally, at the end of the seven (7) week reathletization program at the rate of five (5) sessions per week, we re-evaluated the same variables in the footballer. Thus, the comparison of the values ​​recorded before and after the reathletization program revealed an increase in the thigh perimeter of 3 centimeter, the Maximum Aerobic Speed ​​of 1.18 kilometer per hour, oxygen consumption of 4.13 milliliter per kilogram per minute, the percentage of asymmetry of 3.3 percent in the crossover hop test and the vertical jump of 6.74 centimeter in the Counter movement jump test. It emerges from our case study that an adequate reathletization program after anterior cruciate ligament reconstruction of the knee allowed our young footballer to recover his thigh perimeter, to rebalance the strength of both limbs, to improve his vertical jump and his maximum aerobic speed.

Objective: To study the prevention and management of cardiac accidents during physical education and sports (PES) classes in public middle and high schools in the Dakar region. Methods: A questionnaire was administered to 83 PES teachers in public middle and high schools in Dakar, covering student admission to PES classes, teacher first aid skills, and the existence of infirmaries equipped with defibrillators and competent healthcare personnel. Results: Prevention of cardiac accidents is deemed inadequate, as most teachers do not require a medical examination before admitting students to PES classes. This indicates a negligence of student health. While most teachers have been trained in first aid, a concerning minority remain untrained. There is a strong consensus among teachers to stop physical activity when students show signs of distress (pain, palpitations, dizziness, etc.) during PES classes, highlighting a shared priority for student safety. However, some teachers are still unable to administer first aid in the event of a cardiac accident. Additionally, only seven institutions have a defibrillator, and 36 institutions do not have an infirmary. Conclusion: The lack of a mandatory medical examination for admission to PES classes, the absence of infirmaries equipped with defibrillators in most public middle and high schools, and the hiring of teachers not trained in first aid indicate that Senegalese public schools are far from effectively preventing cardiac accidents and sudden deaths, an issue persisting for the past five years.

In this study, a linear regression approach is used to model 400 m performance. We have choosen to consider the time of the first 100 metres and the age of the athletes as key variables, as they are likely to play a determining role in succeeding in this specific distance. The start, symbolised by the first 100 metres, is often considered a crucial phase in the 400m. Sprinters who manage to maintain rapid acceleration in this first part of the race tend to perform more consistently over the whole 400 metres. Studies have shown that competitive experience can play a significant role in athletic performance. Athletes who have accumulated years of experience often develop more efficient running strategies and better effort management, thus positively influencing their results.
