Rehabilitation for post-COVID-19 condition through a supervised exercise intervention: A randomized controlled trial.

PURPOSE: The aim of the study was to compare the outcomes of patients with post-COVID-19 condition undergoing supervised therapeutic exercise intervention or following the self-management WHO (World Health Organization) rehabilitation leaflet. METHODS: A randomized controlled trial was carried out that included 39 participants with post-COVID-19 condition who had a chronic symptomatic phase lasting >12 weeks. Comprehensive medical screening, patient-reported symptoms, and cardiorespiratory fitness and muscular strength were assessed. Patients were randomly assigned to a tailored multicomponent exercise program based on concurrent training for 8 weeks (two supervised sessions per week comprised resistance training combined with aerobic training [moderate intensity variable training], plus a third day of monitored light intensity continuous training), or to a control group which followed the WHO guidelines for rehabilitation after COVID-19. RESULTS: After follow-up, there were changes in physical outcomes in both groups, however, the magnitude of the change pre-post intervention favored the exercise group in cardiovascular and strength markers: VO2 max +5.7%, sit-to-stand -22.7% and load-velocity profiles in bench press +6.3%, and half squat +16.9%, (p < 0.05). In addition, exercise intervention resulted in a significantly better quality of life, less fatigue, less depression, and improved functional status, as well as in superior cardiovascular fitness and muscle strength compared to controls (p < 0.05). No adverse events were observed during the training sessions. CONCLUSION: Compared to current WHO recommendations, a supervised, tailored concurrent training at low and moderate intensity for both resistance and endurance training is a more effective, safe, and well-tolerated intervention in post-COVID-19 conditions.

Post-COVID-19 Syndrome and the Potential Benefits of Exercise.

The coronavirus disease (COVID-19), caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection, is leading to unknown and unusual health conditions that are challenging to manage. Post-COVID-19 syndrome is one of those challenges, having become increasingly common as the pandemic evolves. The latest estimates suggest that 10 to 20% of the SARS-CoV-2 patients who undergo an acute symptomatic phase are experiencing effects of the disease beyond 12 weeks after diagnosis. Although research is beginning to examine this new condition, there are still serious concerns about the diagnostic identification, which limits the best therapeutic approach. Exercise programs and physical activity levels are well-known modulators of the clinical manifestations and prognosis in many chronic diseases. This narrative review summarizes the up-to-date evidence on post-COVID-19 syndrome to contribute to a better knowledge of the disease and explains how regular exercise may improve many of these symptoms and could reduce the long-term effects of COVID-19.

Estudio descriptivo de lesiones de pádel: relación con el género, edad, nivel de los jugadores y localización de las lesiones / Descriptive study about injuries in padel: relationship with gender, age, players' level and injuries location / Estudo descritivo sobre lesões em padel: relação com gênero, idade, nível de jogadores e localização das lesões

Objetivo: Analizar la relación existente según el género, la edad y el nivel de los jugadores de pádel con la cantidad de lesiones descritas por ellos mismos. Método: Participaron 148 jugadores (75 hombres, 73 mujeres, 34 ± 10 años). Se registraron un total de 151 lesiones clasificadas en función del tipo de lesión, localización anatómica y situación (entrenamiento o competición). Estudio descriptivo retrospectivo utilizando una adaptación de un cuestionario de lesiones deportivas autocompletado por los jugadores. Se utilizó la prueba de Chi-Cuadrado, los Residuos y la V de Cramer para conocer el grado de asociación entre las variables. Resultados: Los resultados mostraron: I) predominio de lesiones musculares en los miembros inferiores; II) alto número de lesiones en el tronco en hombres y de los miembros superiores en mujeres (p = 0.046); III) mayor índice de lesiones musculares en mayores de 35 años y tendinosas en menores de 35 años (p = 0.009); IV) mayor número de lesiones en jugadores de menor nivel, especialmente en tendones y hombro (p = 0.031). Conclusiones: Las lesiones más frecuentes en pádel son las musculares, localizadas en los miembros inferiores. El género masculino presenta más lesiones en el tronco mientras que el número de lesiones en mujeres se centra en el miembro superior. Los jugadores mayores de 35 años presentaron más lesiones musculares mientras que se registró un mayor número de lesiones tendinosas en menores de 35 años. Finalmente, el nivel de los jugadores está relacionado inversamente con el número de lesiones (a mayor nivel, menor número de lesiones)

Objective: To analyze the relationship according to gender, age and level of padel players with the number of self-reported injury history. Method: A total of 148 players (75 men, 73 women, 34 ± 10 years old) take part in this study, from whom 151 injuries were registered and classified regarding the type, location and injury situation (training or competition). A retrospective, descriptive study was set out, using an adapted version of a self-reported sports injury questionnaire. Chi-Squared, Residuals and Cramer's V were calculated to study the strength of association between variables. Results: Findings revealed: I) overall predominance of muscle injuries in the lower limbs; II) greater number of trunk injuries in men and upper limbs in women (p = 0.046); III) higher rate of muscular lesions in players older than 35 years and tendinosis in younger than 35 years (p = 0.009); IV) higher rate of injuries in lower level players, especially in tendons and shoulder (p = 0.031). Conclusions: Muscular accounted for the majority of injuries in padel, particularly on the lower limbs. Males reported more trunk injuries, whilst females suffered more on the upper limbs. Players older than 35 years informed more muscular injuries; by contrast, tendinous injuries prevailed in younger than 35 years. Finally, the level of players revealed an inverse relationship in the number of injuries (the higher the level, the lower the injury rate)

Objetivo: Analisar a relação existente entre com gênero, idade e nível dos jogadores com a quantidade de lesões autor relatadas.

Exploring Game Dynamics in Padel: Implications for Assessment and Training.

Courel-Ibáñez, J, Sánchez-Alcaraz Martinez, BJ, and Muñoz Marín, D. Exploring game dynamics in padel: implications for assessment and training. J Strength Cond Res 33(7): 1971-1977, 2019-A better understanding of in-game competition demands potentially improved coaching strategy and quality. However, there is very limited information about game patterns in padel, a very modern racket sport born in the 70s. The purpose of this study was therefore to quantify and classify game dynamics during the match in professional padel players through a multivariate decision tree approach including technical, spatial, and effectiveness indicators. The results determined 3 main game styles strongly defined by the court zone (net, middle, and baseline). In addition, particular technical, spatial, and effectiveness indicators were identified in each zone. In net and middle areas (offense) stood the use of volleys and overhead strokes on the center lane to both keep a positional advantage and solve the point. Conversely in the baseline (defense), the use of corner side walls and the domain of lobs showed to be relevant. The high rate of backhand groundstrokes, involving over 4 of 10 actions, is also remarkable. This information may have relevant implications for coaches working in padel by providing a novel hierarchically organization of game dynamics, which helps in designing training and conditioning programs close to real competitive situations.
