The modifications that have taken place within youth sports have made games, such as basketball, soccer, or tennis, easier for children to play. The purpose of this study was to determine the effects low compression (LC) tennis balls and scaled tennis courts had on the forehand groundstroke performance of children. The forehand groundstroke performances of eight subjects' (8.10 ± 0.74 yrs) usin...

The aim of this study was to compare heart rate (HR), blood lactate (LA) and rate of perceived exertion (RPE) responses to a tennis-specific interval training (i.e., on-court) session with that of a matched-on-time running interval training (i.e., off-court). Eight well-trained, male (n = 4) and female (n = 4) tennis players (mean ± SD; age: 16.4 ± 1.8 years) underwent an incremental test where...

This paper presents a robotic platform which is targeted to perform the task of a tennis ball boy. This platform is self-contained with on-board sensing and computation, uses only cost-effective off-the-shelf components, and was designed to perform robustly and repeatably in semistructured real-world environments. In particular, this paper presents a particle-filter implementation that allows t...

The angled bounce of a sports ball off a hard surface such as a typical tennis court has been the subject of many studies, for example Thorpe and Canaway (1986), Brody (1983), conferences and in-house reports. During play the tennis ball is hit at a variety of speeds, often with spin imparted to contact and bounce off the tennis court from a range of angles. The characteristics of these angled ...

The aim of this study was to compare the kinematic characteristics of tennis matches between red clay and hard courts in young tennis players. Eight young tennis players performed two tennis matches on different court surfaces. The match activities were monitored using GPS units. The distance covered in different velocity ranges and the number of accelerations were analyzed. The paired t test a...

In tennis, mental toughness is often considered highly important in achieving the elite level. The current study is the first to examine behavioural expressions of mental toughness on the court and their relationships with self-reported measures. Based on the input of five experienced tennis coaches of junior tennis players and behaviours used in previous studies, we developed a taxonomy consis...

In this paper we present an open robotic platform which is targeted to perform the task of a tennis ball boy. Our platform can localize itself and navigate on a tennis court. It can also localize tennis balls lying on the court. It is self-contained with on-board sensing and computation, uses only cost-effective off-the-shelf components, and was designed with an eye for robustness and repeatabi...
