V originále

The term laterality refers to the preference or dominance of the lateral asymmetry of the human body. The prevalence of left-handedness is reported to be 10–13%, but in some sports (e.g. boxing, ice hockey, tennis), the proportion of left-handers is higher. The left-handedness is considered an advantage in tennis; however, the one-sided load can cause muscular dysbalances leading to injuries. The research aim was to assess bilateral differences in handgrip strength in top Czech U14 male tennis players as to injury prevention. The participants were tennis players (n = 232) aged 13.0–14.9 taking part in the regular testing by the Czech Tennis Association using the TENDIAG1 test battery between 2000 and 2019. 87.5% of all players were right-handed (RH) and 12.5% left-handed (LH). The Effect Size Index d was used, which can be interpreted as a small (d = .20), medium (d = .50) or large effect (d = .80). Bilateral differences between the right- and left-hand strength of all players were medium significant (d = .52) in favor of the right hand, probably because of more RH players (n = 203) than LH players (n = 29). The assessment of differences between the right hand of RH and the left hand of LH players showed lower than small differences (d = .13) in favor of RH players. There was a medium significant (d = .62) difference among all players in favor of the dominant hand (DH) over the non-dominant one (NDH). Regarding injury prevention, a difference between DH and NDH force of >15% was found in 5.6% of players (n = 13), which means a high risk in terms of potential injury and >20% (very high risk) in 1.3% of players (n = 3) according to the Bilateral Asymmetry Index 1 (BAI-1). This predicts an increased risk of injury, so it is desirable to pay attention to both sides of the training load and to include compensatory or strengthening exercises.
