The aim of this study was to compare the effects of two plyometric training program (aquatic vs. land) on vertical jump. 65 male physical education students took part in this study and were randomly assigned to three groups: aquatic plyometric training group (APT, n = 20), plyometric training group (PT, n = 20) and control group (CG, n = 25). The training program was performed for 10 weeks with a frequency of 2 sessions per week. Volume was increased from 10 sets of 10 repetitions to 10 sets of 55 repetitions. Both APT and PT increased the performance in CMJ and SJ with respect to pretest (P

Una correcta estrategia de recuperación (ER) tras la competición o el entrenamiento de alta intensidad en fútbol ayudará a no disminuir el rendimiento y a prevenir lesiones. El objetivo de este trabajo fue estudiar la eficacia de diferentes estrategias de recuperación combinadas en comparación con una simple, tras una sesión de entrenamiento específico de fútbol. Participaron 20 jugadores de fútbol de élite y se utilizaron cuatro estrategias de recuperación de forma aleatoria y contrabalanceada a lo largo de 4 semanas de entrenamiento. Se midió temperatura timpánica y las escalas subjetiva Total Quality Recovery (TQR) y Category Ratio Scale (CR10). Los resultados exponen que ninguna de las ER estudiadas muestra ser más eficaz que las demás. No obstante, la realización de protocolos de recuperación combinados llevados a cabo tras la sesión de entrenamiento de fútbol, tiende a una mayor eficacia respecto al protocolo que incluía únicamente estiramientos, After a soccer match or high intensity training, suitable recovery will help not to decrease performance and to prevent injuries. The aim of this study was to test the effectiveness of different combined recovery strategies in comparison with a simple one, after a specific soccer training session. Twenty elite players participated in the study. A randomized crossover design was used to determine the effect of 4 post-training session recovery strategies. Tympanic temperature was measured, as well as Total Quality Recovery (TQR) and Category Ratio Scale (CR10) subjective scales. Results show that none of the recovery strategies proved more effective than others. However, the use of combined strategies tended to be more effective than a simple strategy after a high intensity training session in soccer

La Lucha Canaria (LC) ha sido recientemente reconocida como deporte por el Consejo Superior de Deportes, aunque su origen se pierde en el tiempo. Sin embargo, no hay ningún trabajo en la bibliografía científica que describa qué ocurre fisiológicamente durante la competición en esta modalidad de lucha, y éste es el objetivo del presente trabajo. Con una muestra de 12 luchadores de alto nivel (puntales) simulamos el sistema de competición actual en Lucha Canaria. Se estudió la frecuencia cardiaca, la tensión arterial y la concentración de lactato en sangre en diferentes momentos de la simulación. Los patrones observados de respuesta de FC, TA y lactato, caracterizan a la competición en LC como un ejercicio intermitente, con picos de intensidad que superan el umbral láctico y determinan incrementos importantes de FC y TA sistólica. Este estudio es el primero en que se valora la respuesta fisiológica del luchador canario en competición., The aim of this article is to describe what happens from a physiological point of view in a Canarian Wrestling (CW) contest. The Spanish National Sports Council recognized Canarian Wrestling as a sport on June 1st, 2009, although its origin is not very well documented. No scientific article exists in the scientific literature to describe what happens physiologically during a CW contest. Twelve high level wrestlers were recruited to simulate a CW match. The study involved data about heart rate (HR), blood pressure (BP) and blood lactate levels (L) at different moments of the combat. The conclusions of the data observed concerning HR, BP and L classify Canarian Wrestling as an intermittent exercise, with intensity peaks that exceed the lactic threshold and high levels of HR and systolic BP. This is the first paper in which the physiological responses in a Canarian Wrestling competition are reported.

Ha sido realizada una revisión de 86 artículos, con el objetivo de analizar a través de los estudios más recientes los beneficios y limitaciones de los nuevos sistemas para el análisis del futbolista durante el partido, debido a que las mayores exigencias en el rendimiento del fútbol moderno está obligando a replantearse cuáles son sus demandas físicas, así como los modelos de planificación y los métodos de entrenamiento tradicionales. Los resultados muestran que el vídeo análisis asistido por ordenador para la codificación de los patrones de movimiento y la tecnología GPS se presentan como herramientas de gran utilidad para conocer mejor la carga física del jugador, mientras que el diseño observacional facilita la evaluación del comportamiento técnico-táctico del futbolista y el equipo. Como conclusión podemos decir que hemos observado sin embargo una metodología diferente entre las opciones comerciales disponibles y una tecnología ubicada todavía en una etapa inicial de desarrollo, A review of 86 references has been made, in order to analyze through the most recent studies the benefits and limitations of the new systems for the analysis of soccer player during the match, due to the fact that the greater performance requirements of modern soccer is forcing to review his physical demands, as well as planning models and traditional training methods. The results show that the computer-aided video analysis for coding movement patterns and the GPS technology are presented as very useful tools for a better understanding of the players physical load, whereas the observational design facilitates assessment of the technical-tactical behavior of the soccer player and the team. In conclusion we can say that we have however observed a different methodology among the available commercial options and a technology still placed at an initial stage of development.

The purpose of this study was to compare the effects of landvs. aquatic based plyometric training programs on the drop jump, repeated jump performance and muscle damage. Sixty-five male students were randomly assigned to one of 3 groups: aquatic plyometric training group (APT), plyometric training group (PT) and control group (CG). Both experimental groups trained twice a week for 10 weeks performing the same number of sets and total jumps. The following variables were measured prior to, halfway through and after the training programs: creatine kinase (CK) concentration, maximal height during a drop jump from the height of 30 (DJ30) and 50 cm (DJ50), and mean height during a repeated vertical jump test (RJ). The training program resulted in a significant increase (P < 0.01-0.001) in RJ, DJ30, and DJ50 for PT, whereas neither APT nor CG reached any significant improvement APT showed likely/possibly improvements on DJ30 and DJ50, respectively. Greater intra-group Effect Size in CK was found for PT when compared to APT. In conclusion, although APT seems to be a safe alternative method for reducing the stress produced on the musculoskeletal system by plyometric training, PT produced greater gains on reactive jumps performance than APT.

La determinación del porcentaje de masa grasa en pacientes con lesión medular crónica (LMC) resulta de interés por la alta morbimortalidad cardiovascular que presenta este grupo. En el caso de deportistas, además, permitiría optimizar su rendimiento deportivo. Por consiguiente, el presente estudio se planteó como primer objetivo comparar diferentes métodos de estudio del porcentaje de masa grasa de deportistas con LMC. Y como objetivo secundario, identificar alguna ecuación que permita predecir los niveles de masa grasa de manera más económica, sencilla, rápida y no invasiva. Se diseño un estudio observacional y transversal en el que participaron voluntariamente 8 deportistas varones con LMC a nivel o por debajo de T5 que compiten a nivel nacional. El porcentaje de masa grasa corporal de los participantes se determinó mediante tres metodologías: densitometría (DEXA), antropometría convencional (Ecuación de Siri) e impedancia bioeléctrica (BIA). Este protocolo fue aprobado por un Comité de Ética Institucional. El porcentaje de masa grasa presentado por jugadores de baloncesto en silla de ruedas tras someterse al método de referencia (DEXA) fue del 28,76±9,16%. El análisis de concordancia de Bland-Altman entre métodos sugiere que tanto la antropometría convencional como la BIA subestiman el porcentaje de masa grasa de deportistas con LMC. la ecuación de predicción obtenida fue: Masa Grasa (%)= 1,9197 (pliegue tríceps (mm)) + 6,5063. Tanto las técnicas antropométricas convencionales como la propia BIA subestiman la masa grasa en deportistas con LMC. Asimismo se ha identificado una ecuación de regresión para la predicción del porcentaje de masa grasa de bajo coste y aplicable en cualquier entorno. The assessment of fat mass (FM) is of great interest for people with chronic spinal cord injury (SCI) given that morbidity and mortality from cardiovascular disease are greater and occur earlier in this group. Furthermore, it may play a key role improving physical performance in athletes with SCI. For the reasons already mentioned, the current study was designed to compare different methods for assessing FM in athletes with SCI. A secondary objective was to identify a predictive equation for FM in this group that is easily reproducible elsewhere. A total of 8 male athletes with complete SCI at or below the 5th thoracic level (T5) competing in a national league volunteered for this study. The percentage of FM was assessed by three different methods: conventional anthropometry (Siri equation), bioelectrical impedance analysis (BIA) and densitometry (DEXA). This research was conducted in full accordance with ethical principles, including the World Medical Association Declaration of Helsinki (version, 2002). Furthermore, the present protocol was approved by an Institutional Ethics Committee. Mean percentage of FM assessed by DXA was 28.76±9.16%. Moreover, Bland-Altman plots suggested conventional anthropometry and BIA underestimated fat mass percentage in this group. Lastly, a predictive equation for fat mass was established as follows: FM (%)=1.9197 (triceps skinfold thickness (mm))+6.5063. It was concluded that both conventional anthropometry and BIA underestimated fat mass in athletes with chronic SCI. Furthermore, a predictive equation of fat mass was recommended for this group due to its low cost and wide availability in any clinical setting.

Two types of detraining can be described: short-term detraining with a period of less than 4 weeks, and long-term detraining (period longer than 4 weeks). The purpose of this study is to verify the presence and eventually the magnitude of physiological cardiorespiratory changes in young team sport players after a period of long-term detraining.Fourteen young soccer players (15 ± 1 year) were studied with two incremental tests at the end of the regular season and after a six-week total break period from training activities. Physiological variables were evaluated: heart rate (HR), oxygen uptake (VO₂), volume of ventilation (VE), aerobic (VA) and anaerobic (Van) running speed at thresholds and maximum effort were recorded.This study shows the magnitude of the physiological changes in young players after a period of long-term detraining. The results showed significant decreases at the end of the detraining period of VO₂ at VA of 22.7% (44.54 ± 4.56 vs. 34.41 ± 4.57 mL/kg/min, P0.05), of 25.8% of VO₂ at VAn (54.60 ± 5.81 vs. 40.48 ± 5.07 mL/kg/min, P0.05) and of 21.2% in VO₂ max (62.83 ± 5.77 vs. 49.46 ± 6.51 mL/kg/min, P0.05). Speed at VA (11.5 ± 0.96 vs. 10.7 ± 0.97 km/h; P0.05), speed at VAn (15.3 ± 1.05 vs. 14.2 ± 1.48 km/h; P0.05), peak running speed (18.8 ± 1.20 vs. 17.2 ± 1.1 km/h; P0.05).It is likely that alteration of metabolic parameters may significantly affect the range of physical condition and especially, aerobic-anaerobic resistance and maintenance training would be advisable in young athletes during the transition period. Given the relevance of worsening demonstrated by our data, coaches should avoid very long periods of complete rest (no more than 15 days) at the end of the season.

En este trabajo se exponen los criterios de positividad del Comité Olímpico Internacional versus a la Sociedad Española de Neumología y Cirugía Torácica. Participaron en este estudio ochenta deportistas de alto rendimiento, realizando una historia clínica, una espirometría de reposo y un test de metacolina. Se analiza la sensibilidad y especificidad del test de metacolina mediante curvas ROC. El comité Internacional antidopaje (WADA) requiere que la disminución sea con un PC20 < a 4mg/ml, mientras que para la práctica clínica este descenso debe presentar un PC20 < 8mg/ml. Los resultados fueron: 25% tuvieron un PC20 > de 8mg/ml; el 61% obtuvieron un PC20 < 4mg/ml y un 14% presentaron un PC20 entre 4 y 8mg/ml, correspondiendo el mejor punto de corte a PC20 de 7,6mg/ml con especificidad de 98,3 y sensibilidad de 100%. Se tendría que determinar los mismos criterios para el diagnóstico de los deportistas y los que no lo son., In this work criteria of the International Olympic Committee versus the Spanish Society of Pneumology and Thoracic Surgery are exposed. A study was conducted in eighty high performance athletes of several sports . Who underwent a medical history, resting spirometry and a methacholine challenge test. You get the sensitivity and specificity of methacholine challenge test using Receiver Operating Curves (ROC curves). International anti-doping Committee requires that the decline is a PC20 < 4mg/ml, while clinical practice this fall must submit a PC20 < 8mg/ml. Twenty five percent of those studied had a PC20 > of 8mg/ml, 61% had a PC20 < 4mg/ml and 14% had a 4 to 8mg/ml PC20. The best cutoff point was found for a PC20 of 7.6 mg/ml with a specificity of 98.3 and a sensitivity of 100%. It would have to determine the same criteria for positive diagnosis of athletes and those who are not.

El presente estudio pretende identificar correlaciones estadísticamente significativas entre parámetros de masa grasa abdominal obtenidos por densitometría (DXA) y otros de tipo cineantropométrico (índices de distribución de masa grasa) y bioquímico (perfil lipídico) en mujeres postmenopausicas con síndrome metabólico. Se diseño un estudio de cohortes histórico que incluyó a un total de 1326 mujeres post-menopausicas con edad > 45 años que se habían sometido rutinariamente a DXA para conocer su densidad mineral ósea entre Enero de 2006 y Enero de 2011. Se utilizó un DXA tipo Lunar DPX-L para determinar la masa grasa abdominal en las regiones de interés L1-L4 y L3-L4. Además del DXA, se obtuvo de cada participante la correspondiente anamnesis, bioquímica, tensión arterial e índices de distribución de masa grasa mediante técnicas antropométricas convencionales. Se utilizó la clasificación NCEP-ATP-III para el diagnóstico de síndrome metabólico. Este protocolo fue aprobado por un Comité de Ética Institucional. La mayor fuerza de asociación se estableció entre el porcentaje de masa grasa L1-L4 obtenido por DXA y el perímetro de la cintura (r= 0,77; p= 0,0016) además de con colesterol-HDL (r= -0,58; p= 0,0290). Finalmente se concluye que el perímetro de la cintura y los niveles de colesterol-HDL podrían recomendarse como predictores del comportamiento de la masa grasa abdominal de regiones de interés L1-L4 y L3-L4 obtenidas por DXA en mujeres postmenopausicas con síndrome metabólico. The current study was conducted to identify potential correlations between abdominal fat mass obtained by DXA and several parameters obtained by anthropometric conventional techniques as well as lipid profile in postmenopausal women with MS. This historical cohort study included a total of 1326 postmenopausal women aged > 45 years old who had routinely undergone DXA to measure their bone mineral density between January 2006 and January 2011. The regions of interest envisaged in our study by using DXA were the lumbar regions L1-L4 and L4-L5. At the same time, they underwent a complete medical examination including personal medical history assessment, biochemical blood analysis, blood pressure measurements and anthropometrical evaluation. Metabolic syndrome was diagnosed attending to the criteria established by National Cholesterol Education Program Adult Treatment Panel III (NECP-ATP-III). This protocol was approved by an Institutional Ethics Committee. Several significant correlations were found between DXA and indices of body fat distribution as well as lipid profile. The strongest correlations were found between fat mass L1-L4 and waist circumference (r= 0.77; p= 0.0016) and levels of HDL-cholesterol (r= -0.58; p= 0.0290). It was concluded that waist circumference and HDL-cholesterol may be recommended to predict fat mass in regions of interest L1-L4 and L3-L4 in postmenopausal women with MS.

The purpose of this study is to verify the presence and eventually the magnitude of physiological cardiorespiratory changes in young team sport players after a period of long-term detraining., Methods: Fourteen young soccer players (15 ± 1 year) were studied with two incremental tests at the end of the regular season and after a six-week total break period from training activities. Physiological variables were evaluated: heart rate (HR), oxygen uptake (VO₂), volume of ventilation (VE), aerobic (VA) and anaerobic (Van) running speed at thresholds and maximum effort were recorded., Results: This study shows the magnitude of the physiological changes in young players after a period of long-term detraining. The results showed significant decreases at the end of the detraining period of VO₂ at VA of 22.7% (44.54 ± 4.56 vs. 34.41 ± 4.57 mL/kg/min, P<0.05), of 25.8% of VO₂ at VAn (54.60 ± 5.81 vs. 40.48 ± 5.07 mL/kg/min, P<0.05) and of 21.2% in VO₂ max (62.83 ± 5.77 vs. 49.46 ± 6.51 mL/kg/min, P<0.05). Speed at VA (11.5 ± 0.96 vs. 10.7 ± 0.97 km/h; P<0.05), speed at VAn (15.3 ± 1.05 vs. 14.2 ± 1.48 km/h; P<0.05), peak running speed (18.8 ± 1.20 vs. 17.2 ± 1.1 km/h; P<0.05)., Conclusion: It is likely that alteration of metabolic parameters may significantly affect the range of physical condition and especially, aerobic-anaerobic resistance and maintenance training would be advisable in young athletes during the transition period. Given the relevance of worsening demonstrated by our data, coaches should avoid very long periods of complete rest (no more than 15 days) at the end of the season.
