    ABSTRACT: Scoring in a basketball game is a process highly dynamic and non-linear type. The level of NBA teams improve each season. They incorporate to their rosters the best players in the world. These and other mechanisms, make the scoring in the NBA basketball games be something exciting, where, on rare occasions, we really know what will be the result at the end of the game. We analyzed all the games of the 2005-06, 2006-07, 2007-08, 2008-09, 2009-10 NBA regular seasons (6150 games). We have studied the evolution of the scoring and the time intervals between points. These do not behave uniformly, but present more predictable areas. In turn, we have analyzed the scoring in the games regarding the differences in points. Exists different areas of behavior related with the scorea and each zone has a different nature. There are point that we can consider as tipping points. The presence of these critical points suggests that there are phase transitions where the dynamic scoring of the games varies significantly.

    ABSTRACT: This study was designed to analyze changes in muscle response after cold-water immersion. The vastus lateralis of the dominant leg was analyzed in 12 professional soccer players from the Spanish 2nd Division B using tensiomyography, before and after four cold-water immersions at 4°C lasting 4 mins each. Core temperature, skin temperature, and heart rate were monitored. A significant interaction (P ≤ 0.05) was found in muscle deformation between control conditions (5.12 ± 2.27 mm) and (1) immersion 3 (3.64 ± 2.27 mm) and (2) immersion 4 (3.38 ± 1.34 mm). A steady decrease was also observed in response velocity (immersion 1, -7.3%; immersion 2, -25.9%; immersion 3, -30.0%; immersion 4, -36.6%) and contraction velocity (immersion 1, -11.5%; immersion 2, -22.1%; immersion 3, -35.0%; immersion 4, -41.9%), with statistically significant differences (P ≤ 0.05) in relation to the reference values commencing with the third immersion. No significant differences were found between control conditions in subsequent exposures to cold water for the values of response time and contraction time. Sustained time and reaction time showed an increase during repeated exposures and with longer exposure time, although the increase was not statistically significant. This study shows that repeated cold-water immersions (4 × 4 mins at 4°C) cause considerable alterations to muscle behavior. These alterations significantly affect the state of muscles and their response capacity, particularly in relation to muscle stiffness and muscle contraction velocity.

    ABSTRACT: The present study aims to describe the behavior of the heart rate variability (HRV) in the time-frequency domain during the conduct of an incremental test, using Wavelet Transform (WT). Have been studied 8 cyclists healthy male subjects (age: 17.12 ± 1.11 years; height: 1.73 ± 0.06 m, weight: 69.96 ± 8.03 kg) practitioners in cycling track, which conducted a test ergoespirométrica a cicloergómetro following an incremental protocol (increases of 5W/12s) until exhaustion. The analysis of the WT of HRV has been done by establishing three zones of effort on the spectrogram of the signal: zone 1 or activation zone, with frequencies below 150 beats per minute (ppm), the zone 2 or transition zone, with frequencies below 185 ppm and zone 3 or crisis zone, above 185 ppm. This method of analysis is a simple and reliable tool for locating phase transitions in the behavior of the HRV signal during an incremental effort. This useful cheap and noninvasive tool allows to control the effect of training load and helps to establish benchmarks in the intensity of work.

    ABSTRACT: Objetivo. El presente estudio tiene por objetivo evaluar la relación existente entre el volumen semanal de entrenamiento realizado por los triatletas, como parte de su entrenamiento habitual, y el porcentaje de espermatozoides que exhiben una morfología normal (morfología espermática). Métodos. Los valores de 15 triatletas varones, que compiten tanto nacional como internacionalmente, fueron evaluados. Todos los sujetos debían haber participado en la prueba Ironman y haberla completado. Se realizó un análisis detallado del volumen de entrenamiento realizado en cada modalidad. La evaluación morfológica se llevó a cabo siguiendo los criterios estrictos de Kruger. Los estudios de correlación se realizaron para verificar la relación entre el volumen semanal de entrenamiento (total y para cada modalidad) y la morfología espermática. Resultados. La evaluación detallada del entrenamiento reveló los siguientes valores (media ± desviación estándar) para las tres modalidades que practican los triatletas: carrera 49,42 ± 7,37 km; natación 11,31 ± 3,05 km y ciclismo 330,77 ± 56,04 km. Los valores de normalidad de morfología espermática mostraron una correlación estadística inversa (r = -0,71; p < 0,01) con el volumen de ciclismo. Los sujetos que tenían menos del 4% de formas normales, considerados con pronóstico pobre, realizaban sistemáticamente más de 300 km/semana. Conclusión. Existe una alta correlación inversa entre el porcentaje de espermatozoides con morfología normal y el volumen semanal de ciclismo en los triatletas. Se puede concluir, por tanto, que un alto volumen de ciclismo, especialmente por encima de los 300 km/semana, es perjudicial para la morfología espermática y puede llevar a un serio impedimento en la fertilidad masculina

    ABSTRACT: Objetivo: El propósito del presente estudio fue analizar la relación de la resistencia de base general con la resistencia de base especial en el voleibol profesional, a lo largo de una temporada. Nuestra hipótesis es que se puede lograr un incremento de la resistencia de base especial, sin una mejora concomitante de la resistencia de base general. Métodos: Se realizó un estudio longitudinal de 11 jugadoras, pertenecientes a la plantilla de un equipo profesional de voleibol, durante la temporada 2006-2007. Para al análisis de las resistencias de base general y especial se valoró el VO2máx, Umbral Anaeróbico mediante ergometría en tapiz y la altura media obtenida en el Test de saltos múltiples (RJ – 15’’), en diferentes momentos de la temporada. Resultados: La resistencia de base general se comportó de forma estable a lo largo de la temporada, mientras que la resistencia de base especial tuvo ganancias y pérdidas, estadísticamente significativas. Conclusión: Se concluye que, para aumentar la resistencia de base especial no es necesaria una mejora simultánea de la resistencia de base general.

    ABSTRACT: Os sistemas que encontramos na natureza se organizam de forma hierárquica, ou seja, se configuram em estratos que correspondem a escalas características de tempo, longitude ou energia. Por escala nos referimos à dimensão espacial ou temporal de um fenômeno e há três aspectos a considerar: a escala característica, o efeito de escala e o escalamento. A lei de escala, que segue muitos fenômenos naturais, é descrita por leis de potência, que são expressões matemáticas do tipo Y=cXb; onde X e Y são duas variáveis, quantidades ou observações, c é uma constante e b é o expoente de escala. Uma expressão deste tipo tem duas propriedades fundamentais: 1) sua transformação logarítmica se transforma em uma reta [log(Y) = log(c) + b log(X)]; 2) é invariante a mudanças de escala. Há, basicamente, quatro âmbitos nos quais estas funções se utilizam: no estudo de sistemas de tipo biológico (leis alométricas); na geometria fractal, onde se usam para a determinação das dimensões fractais; em certos tipos de redes complexas; e no estudo das distribuições de probabilidade com comportamentos livres de escala. Sua utilidade no esporte é recente e abre uma nova linha metodológica na pesquisa aplicada, permitindo abordar, com ferramentas simples, uma infinidade de temas relacionados com a estrutura do esporte, sua manifestação na competição e a forma de treiná-lo.

    ABSTRACT: Purpose. This study aims to compare the relationship between the ventilatory thresholds and the aerobic and anaerobic thresholds obtained by continuous wavelet transform (CWT) of heart rate variability (HRV). Methods. Eight healthy, trained, male cyclists (age: 17.12 ± 1.11 years; height: 1.73 ± 0.06 m; weight: 69.96 ± 8.03 kg) underwent an ergospirometric test on a cycloergometer, performing an incremental protocol until exhaustion. The cardiac signal was recorded using cardiotachometers. The aerobic-anaerobic transition phase was identified by wavelet analysis using the kinetics of the maximum spectral energy peaks (fp) of the HRV high-frequency (HF) and very high-frequency (VHF) bands, and those of the product of the HFVHF instantaneous spectral power (ms2) and fp (PS·fp). The aerobic and anaerobic thresholds obtained were compared to those provided by the standard analysis of gas exchange variables. Results. No significant differences were observed between the aerobic and anaerobic thresholds identified by wavelet analysis involving either fp or PS·fp, and those identified by the respiratory exchange variables. Bland-Altman plots showed that both methodologies identified identical transition zones. When the comparison variable used in the wavelet analysis was fp, a close agreement was seen with the gaseous exchange variable analysis in terms of the aerobic threshold; the relationship was less strong for the anaerobic threshold. When the comparison variable was PS·fp, the relationship between the methodologies was again within the acceptable range, although this time agreement was stronger for the anaerobic threshold. Conclusion. Wavelet analysis of the HRV is a valid method for identifying the aerobic-anaerobic transition phase

    ABSTRACT: Introdução: O trabalho analisa e descreve o comportamento do sistema respiratório e o sistema de contribuição de oxigênio durante uma prova de intensidade moderada realizada em um cicloergômetro. Materiais e Métodos: Utilizou-se uma amostra de 10 sujeitos (idade: 17,94±2,51 anos; peso: 69,08±7,32kg; altura: 1,73±0,05m), com 4,55±0,72 anos de experiência em ciclismo. Todos fizeram duas provas. A primeira, uma prova incremental até o esgotamento (? de 5W cada 12s, a partir de 100W) que serviu para determinar o VO2máx, os limiares ventilatórios e a carga de trabalho para a prova de carga estável em intensidade moderada (PEM). Na PEM trabalharam durante 30s com uma carga individualmente determinada (249,50±18,02W a 3,64±0,38W.kg-1). Resultados: A carga na PEM foi de 58,82±2,48% da carga máxima atingida na prova incremental e 67,60±5,46% da carga no limiar anaeróbico na mesma prova. Discussão: Em nosso estudo, o VO2 aumentou à razão de 8,8ml.kg-1.min-1, no início da prova, até chegar aos 90,17±2,9% no início da Fase 3 ou de estado estável (5t). A partir deste ponto, os sujeitos estudados mostraram um aumento suave e progressivo do VO2, até aproximadamente os 12min de exercício, quando estabilizaram a resposta até o final da prova.

    ABSTRACT: This study was performed to compare the effects of two different modalities of special power training for the improvement on the vertical jumping, in which the players of the Gran Canaria Volleyball Club were trained during the sessions of 93/94 and 95/96. The training groups were: A) (n = 7), session 93/94, trained only with overload, by using, as transformation, just volleyball training. B) (n = 6), session 95/96, add to this method plyometric exercises for the enhancement weight training. The test items used to prove the results were based on Bosco: Squat Jump (SJ), Countermovement (CMJ), Squat Jump with load (SJbw), Abalakov with block technique (Block) and Drop Jump (DJ) from different heights. On the one hand, gains in height of vertical jump were observed after a method of training that includes plyometric excercise at medium and medium-high intensity and by each different depth jumps (DJ), specially in those ones selected for the transformation of weight training. On the other, when any plyometric method was used there was no enhancement, but a loss of height in vertical jumping.
