Physiological responses in tennis and running with similar oxygen uptake

Abstract

The purpose of the study was to compare selected physiological responses during singles tennis match play and continuous running at a similar mean oxygen uptake (VO2). The study consisted of two main parts, which were separated by 1 week. In the first part, 12 nationally ranked senior tennis players [six females and six males; 47.2 (6.6) years old and 47.0 (5.4) years old, respectively] each completed a 2-h singles tennis match (TE). Mean VO2 during TE [23.1 (3.1) ml.kg(-1). min(-1) for the women and 25.6 (2.8) ml.kg(-1).min(-1) for the men] was measured by a portable spirometry-telemetry system and corresponded to 56% (women) or 54% (men) of their respective maximum VO2. In the second part, the relative VO2 data measured during TE were used to set a similar workload during a 2-h treadmill run at a constant level (RU). At the measured time points, heart rate [140.1 (15.5) beats.min(-1) vs 126.4 (15.1) beats. min(-1)], lactate concentration [1.53 (0.65) mmol.l(-1) vs 1.01 (0.38) mmol.l(-1)] and glucose concentration [5.45 (0.84) mmol.l(-1) vs 4.34 (0.56) mmol.l(-1)] in capillary blood, as well as the respiratory exchange ratio [0.93 (0.03) vs 0.88 (0.03)], were higher (P<0.05) in TE compared to RU. Serum concentrations of free fatty acids increased (P < 0.05) during both work loads [from 0.25 (0.15) mmol.l(-1) to 1.31 (0.44) mmol.l(-1) in TE and from 0.22 (0.17) mmol.l(-1) to 1.24 (0.35) mmol.l(-1) in RU]. Post-exercise urine concentrations of epinephrine [0.17 (0.14) micromol.l(-1) vs 0.08 (0.04) micromol.l(-1)] and norepinephrine [1.27 (0.59) micromol.l(-1) vs. 0.55 (0.33) micromol.l(-1)] were higher in TE (P<0.05). These results indicate a stronger metabolic emphasis on glycolysis and glycogenolysis and an overall enhanced sympathoadrenal activity during tennis match play compared to continuous running exercise at a similar mean VO2.

Efecto del género y del resultado final del partido en competiciones profesionales de pádel. [Effect of gender and match outcome on professional padel competition].

“…As consequence, research in padel practitioners is rather poor with respect to that of other similar racket sports such as tennis (Ferrauti, Bergeron, Pluim, & Weber, 2001;O´Donoghue & Ingram, 2001;Smekal et al, 2001), badminton (Cabello & González-Badillo, 2003;Faude et al, 2007, Ooi et al, 2009, and squash (Chin, Steininger, So, Clark, & Wong, 1995;Girard et al, 2007). More recent research have remarked this need (Villena-Serrano, Castro-López, Lara-Sánchez, & Cachón-Zagalaz, 2016) observing a lack of padel investigations in the available research.…”

A suplementação de carboidrato maximiza o desempenho de tenistas?

“…Já, em Wimbledon (quadra rápida de grama), a duração média do ponto é de 4,3 ± 1,6 segundos, pois os jogadores procuram com mais frequência o término do ponto próximo da rede (7) . Além da análise do jogo, a fim de investigar a sobrecarga fisiológica imposta pela prática do tênis, alguns estudos utilizaram marcadores, como a concentração de lactato, o perfil da frequência cardíaca e o consumo máximo de oxigênio (VO 2max ) durante as partidas ou em testes laboratoriais (8)(9)(10)(11)(12)(13)(14) . Esses estudos revelaram que a sobrecarga fisiológica de uma partida é modesta.…”

Características físicas y antropométricas, y análisis de juego en jugadores de pádel de elite

“…Al igual que en otros deportes de raqueta, en el pádel, la actividad física implica esfuerzos de alta intensidad como sprints, saltos y golpeos agresivos de la pelota, intercalados con periodos de baja o nula intensidad (Martin, 2013). En las investigaciones precedentes se han analizado las características antropométricas, fisiológicas y de juego en otros deportes de raqueta como el tenis (Christmass et al, 1998;Ferrauti et al, 2001;Méndez-Villanueva et al, 2007;Méndez-Villanueva et al, 2010;Kovacs, 2007;Girard y Millet, 2009;Fernández-Fernández et al, 2007;Fernández-Fernández et al, 2008;Fernández-Fernández et al, 2009), el badminton (Faude et al, 2007;Cabello y González-Badillo, 2003;Torres et al, 2004), el squash (Wells et al, 2004;Vuckovic et al, 2004;Girard et al, 2007) o el tenis de mesa (Zagatto et al, 2010), dichas investigaciones han contribuido al desarrollo del juego y a concretar las necesidades específicas de cada uno de ellos.…”
