Description From the general viewpoint, the notion of laterality relates to the preference or dominance as to the side asymmetry of the human body. Preference means that the surer, more accurate, coordinated, and often also stronger side is chosen from the viewpoint of motor manifestations. The stated percentage of the left-handed preference is 10-13%, in some sports (e.g. boxing, hockey, tennis), the proportion of left-handers is higher and the percentage of left-handers among the top female players is higher (16%). The one-sided load in tennis can result in an overload of certain muscle groups of the playing hand and in development of muscular dysbalances, which can lead to injury. The research objective was to find out the level of somatic and strength characteristics and to assess lateral differences in the maximum hand strength of the top Czech female tennis players. The research population was composed of female tennis players in the age of 9-10.9 years (n=65, body height: H=145.30±7.50 cm, body weight: W=36.76±6.10 kg) who took part in the regular testing of the Czech Tennis Association in 2000-2015. The basic anthropometric characteristics were measured (height and weight) and also the maximum hand strength using the hand dynamometer (Grip D, Takei).
