ResumenEl objetivo del presente estudio fue analizar la estructura temporal y las acciones características del pádel de élite. Se analizaron 9 torneos del Padel Pro Tour ® 2012 con un total de 28 partidos y 59 sets (32 categoría masculina vs. 27 femenina). Los partidos fueron analizados mediante el software LongMatch V.0.20.1 ® , comparando ítems sobre aspectos temporales y acciones de juego entre hombres y mujeres. Los resultados ponen de manifiesto diferencias significativas en la mayoría de las variables temporales analizadas. Además, se encontró que el índice de esfuerzo fue significativamente superior en mujeres que en hombres. Por otro lado, las acciones de juego como el número de globos/punto o el número de golpes/punto también fueron significativamente superiores en mujeres con respecto a los hombres. Se podría afirmar que el pádel de élite es un deporte caracterizado por puntos de corta duración alternados con breves periodos de pausa, lo que implica una alta densidad de trabajo, donde el género influye significativamente en las variables temporales y acciones de juego. AbstractThe aim of the present study was to analyze the temporal structure and activity patterns of elite paddle games. 9 Padel Pro Tour ® 2012 tournaments were analyzed and a total of 28 matches and 59 sets (32 male games vs. 27 female games) were considered. The games were scored by using the software LongMatch V.0.20.1 ® , which compare the items based on temporal aspects and activity patterns between males and females. The results show significant differences overall for the temporal variables and the duration of rallies in males and females. Additionally, the variable 'effort ratio' was significantly higher in females than males. Activity variables such as lob per rally and shots per rally were also significantly higher in females than males. We can define the elite paddle as a sport characterized by short-term rallies interspersed with short recovery periods, which imply a high work to rest ratio and gender significantly effects the temporal variables and activity patterns.

García-Benítez, S, Courel-Ibáñez, J, Pérez-Bilbao, T, and Felipe, JL. Game responses during young padel match play: age and sex comparisons. J Strength Cond Res 32(4): 1144-1149, 2018-The purpose of this study was to assess match activity profile and temporal structure in U-16 and U-18 male and female padel players from the 2014 Spanish Youth National Championship. A total of 1,670 rallies from 12 matches were recorded through systematic observation. Variables pertaining to game and point duration, rest interval time, number of strokes per rally (SR), and match total duration were registered. Current findings show that significant influences of age and sex on game demands in youth padel players strengthen the importance of knowing specific game characteristics during formative stages for training accordingly. In particular, padel match activity in youth players was characterized by longer rallies, longer resting interval time, and more number of SR compared with other racket sports, resulting in lower effort index. More specifically, results revealed an increment on match requirements in U-18 players compared with U-16. Besides, we found a greater use of lobs in females, particularly in U-16 players. This information may constitute a useful guide for the design of appropriate game strategies and specific-training sessions according to competitive demands in youth padel players.

Owing to the risk of severe rhabdomyolysis, clinicians advise McArdle disease patients to refrain from strenuous exercise, particularly weight lifting. A 15-year-old male McArdle disease patient performed a 6-week, supervised, light- to moderate-intensity (~65-70% of one-repetition-maximum) resistance (weight lifting) training program (2 sessions/week). Training resulted in ~27% and ~6% increase in one-repetition-maximum bench press and multipower squat performance while inducing no myoglobinuria. The patient changed to a lower disease severity class, that is, he became virtually asymptomatic in terms of exercise limitations. The authors' preliminary data suggest that supervised, light to moderate resistance training is feasible in children with McArdle disease and has potential clinical benefits.
