Sequencing Effects of Neuromuscular Training on Physical Fitness in Youth Elite Tennis Players.

Fernandez-Fernandez, J, Granacher, U, Sanz-Rivas, D, Sarabia Marín, JM, Hernandez-Davo, JL, and Moya, M. Sequencing effects of neuromuscular training on physical fitness in youth elite tennis players. J Strength Cond Res 32(3): 849-856, 2018-The aim of this study was to analyze the effects of a 5-week neuromuscular training (NMT) implemented before or after a tennis session in prepubertal players on selected components of physical fitness. Sixteen high-level tennis players with a mean age of 12.9 ± 0.4 years participated in this study, and were assigned to either a training group performing NMT before tennis-specific training (BT; n = 8) or a group that conducted NMT after tennis-specific training (AT; n = 8). Pretest and posttest included: speed (5, 10, and 20 m); modified 5-0-5 agility test; countermovement jump (CMJ); overhead medicine ball throw (MBT); and serve velocity (SV). Results showed that the BT group achieved positive effects from pretest to posttest measures in speed (d = 0.52, 0.32, and 1.08 for 5, 10, and 20 m respectively), 5-0-5 (d = 0.22), CMJ (d = 0.29), MBT (d = 0.51), and SV (d = 0.32), whereas trivial (10 m, 20 m, CMJ, SV, and MBT) or negative effects (d = -0.19 and -0.24 for 5 m and 5-0-5, respectively) were reported for the AT group. The inclusion of an NMT session before the regular tennis training led to positive effects from pretest to posttest measures in performance-related variables (i.e., jump, sprint, change of direction capacity, as well as upper-body power), whereas conducting the same exercise sessions after the regular tennis training was not accompanied by the same improvements.

Individualized exercise prescription in non-alcoholic steatohepatitis: a case report.

The effect of an individualized exercise programme on a non-alcoholic steatohepatitis case is presented. Before entering the programme the patient was treated with conventional recommendations on diet plus aerobic exercise during fourteen years, without major improvements of his analytical parameters.Two years after including him in a tailored exercise programme, aimed to fulfil the recommendations of the American College of Sports Medicine, his blood markers of liver dysfunction and cardiometabolic risk tended to improve. Consequently, our data support the idea that in non-alcoholic steatohepatitis the exercise-based therapeutic interventions should be individualized taking into account the cardio-respiratory and muscular fitness of the patient, rather than using generic behavioural recommendations.

Prescripción individualizada de ejercicio en un caso de esteatohepatitis no alcohólica / Ultrasound-guided percutaneous drainage and sclerotherapy in a patient with isolated autosomal dominant polycystic liver disease

Se presenta un caso de esteatohepatitis no alcohólica de dieciséis años de evolución, tratado durante catorce años con recomendaciones dietéticas y de práctica de actividad física regular y que, en los dos últimos años, fue incluido en un programa de ejercicio controlado, monitorizado y supervisado, acorde a las recomendaciones del American College of Sports Medicine. Tras la inclusión del paciente en este programa se observó un cambio en la tendencia de diferentes parámetros analíticos de función hepática y riesgo cardiometabólico, que pasaron de mostrar una tendencia al alza, a estabilizarse o tender a disminuir. A raíz de estas observaciones se sugiere que la mera recomendación de realización autónoma de ejercicio regularmente, sin evaluación de la condición física del sujeto, así como sin unas adecuadas planificación y periodización del mismo, puede resultar una medida ineficaz en el tratamiento de esta enfermedad
