The aim of this investigation was to examine physiological demands single match play in tennis.20 players performed 10 matches 50 min. Respiratory gas exchange measures (RGEM) and heart rates (HR) were measured using two portable systems. Lactate concentration determined after each game. average oxygen uptake (VO2) 270 games 29.1 +/- 5.6 mL.kg-1.min-1 (51.1 10.9% VO2max). Average VO2 for a game ranged from 10.4 47.8 (20.4 86.8% lactate (LA) 2.07 0.9 mmol.L-1 (ranging 0.7 5.2 mmol.L-1)....

Physical exercise leads to temporary ischemia in muscles, followed by increased oxygen supply during recovery as a result of reperfusion. It is thought that the sudden influx causes calcium overload cells, leading an inflammatory cells into reperfused tissue. This generation reactive radicals and subsequent oxidative damage DNA, proteins, lipids. For example, oxidant production mitochondria muscles acute exercise, reoxygenation, was shown cause cellular (1). In addition, may transient muscle...

Purpose: Numerous investigations have reported changes in metabolic and cardiorespiratory responses associated with the menstrual cycle. We examined whether variables commonly used exercise testing are influenced by cycle phases. Methods: Nineteen eumenorrheic women performed two incremental tests to voluntary exhaustion on a ergometer during different phases of cycle: follicular phase (FP) luteal (LP). Our study were power output, V˙O2, HR, V˙E, RER, ventilatory equivalents oxygen...

Treadmill testing (TT) commonly used in endurance is often not sport-specific. Therefore a field test (FT) for tennis players was developed. The purpose 1) to compare metabolic and cardiorespiratory response between TT FT 2) assess stroke ratings during FT. In both tests ventilatory variables (VO2, VE, VT, Bf, VE x VO2(-1)), heart rate (HR), lactate (LA) were measured. For an "individual anaerobic threshold" (IAT) calculated. comparison of yielded significant differences response. LA...

Abstract Defects in skeletal muscle energy metabolism are indicative of systemic disorders such as obesity or type 2 diabetes. Phosphorus magnetic resonance spectroscopy ( 31 P-MRS), particularly dynamic P-MRS, provides a powerful tool for the non-invasive investigation muscular oxidative metabolism. The increase spectral and temporal resolution P-MRS at ultra high fields (i.e., 7T) uncovers new potential previously implemented techniques, e.g., saturation transfer (ST) highly resolved...

Post-Activation Potentiation (PAP) is a phenomenon which can improve power performance executed after previous conditioning activity. PAP usually evoked through heavy resistance or plyometric exercise. It has been suggested to refer as Postactivation Performance Enhancement (PAPE) when research field-based on explosive activities. To our best knowledge, no studies have investigated the effects of PAPE deceleration performance, key factor in sports involving change directions. Therefore, aim...
