Endurance development for 10-12 & under tennis players

Abstract

Within classical definition endurance is understood as the ability to perform hard or long-lasting physical activities involving large muscle groups, without the fast increase in fatigue and changes in inner environment of the organism. This definition also includes the strain tolerance and the ability of recovery (Astrand 1987, Kozłowski & Nazar 1999). This definition suits well into such sports like long-distance running, swimming, Nordic skiing, and so mostly “cyclic” sports. For these sports endurance is a factor limiting performance and there is almost a linear correlation between level of endurance and sport performance.
