PLoS ONE 10(6):Įditor: Maria Francesca Piacentini, University of Rome, ITALY Aerobic fitness appears to determine the metabolic intensity that players can sustain throughout the game.Ĭitation: Baiget E, Fernández-Fernández J, Iglesias X, Rodríguez FA (2015) Tennis Play Intensity Distribution and Relation with Aerobic Fitness in Competitive Players. ![]() We conclude that players spent more than 75% of the time in their low-intensity zone, with less than 25% of the time spent at moderate to high intensities. Players with better aerobic fitness play at relatively lower intensities. Moderate to high positive correlations were found between VT 1, VT 2 and VO 2max, and the percentage of playing time spent in zone 1 (r = 0.68–0.75), as well as low to high inverse correlations between the metabolic variables and the percentage of time spent in zone 2 and 3 (r = -0.49–0.75). When expressed relative to VO 2max, percentage of playing time in zone 1 (77 ± 25%) was significantly higher (p < 0.001) than in zone 2 (20 ± 21%) and zone 3 (3 ± 5%). Intensity zones (1: low, 2: moderate, and 3: high) were delimited by the individual VO 2 values corresponding to VT 1 and VT 2, and expressed as percentage of maximum VO 2 and heart rate. Two weeks later the participants played a simulated tennis set against an opponent of similar level. ![]() Ventilatory and gas exchange parameters were monitored using a telemetric portable gas analyser (K4 b 2, Cosmed, Rome, Italy). 20 male players of advanced to elite level (ITN) performed an incremental on-court specific endurance tennis test to exhaustion to determine maximal oxygen uptake (VO 2max) and the first and second ventilatory thresholds (VT 1, VT 2). The aims of this study were (i) to describe the relative intensity of simulated tennis play based on the cumulative time spent in three metabolic intensity zones, and (ii) to determine the relationships between this play intensity distribution and the aerobic fitness of a group of competitive players. ![]()
