Body segments cooperation during forehand stroke production in young and adult tennis players

Abstract

Zuša, A., Lanka, J., Vagin, A., & Cicchella, C. (2015). Body segments cooperation during forehand stroke production in young and adult tennis players J. Hum. Sport Exerc., 9(Proc1), pp.S161-S168. The purpose of the study was to investigate biomechanical characteristics of the forehand stroke production in adult and young tennis players, such as body segments cooperation, separation angle (x-factor) and max speed of a racquet. Kinematic data was collected with an optoelectronic motion capture system Qualisys. Participants in the experiment were 6 mid-level adult tennis players (age 19.5 ± 2.3 years, weight 66.8 ± 7.7 kg, height 170.5 ± 7.8 cm, sports experience 13.2 ± 1.7 years) and 4 young tennis players (age 11 ± 0.6 years, weight 43.5 ± 4.8 kg, height 156.3 ± 4.8 cm, sports experience 5 ± 0.5 years). The task of the motion was to carry out 3 forehand strokes for 3 times, the position of the feet and type of stance was not regulated. Results showed that racquet speed during forehand follow through phase, is significantly higher in adult players. Adult athletes have significantly higher x-factor values, which indicates that they more effectively implement muscle-tendon complex pre-stretching principle during backswing and forward swing phase. As well as adults, young tennis players also perform principle of sequential action of body segments during the stroke production, according to their technical skills and level of training.

“…It was also evident that after the ten forehands, some players presented lower symmetry indexes due to the unused non-dominant upper limb and the lack of dominant limb strength after use, which decreased the index. In comparison with other studies, it was verified that the dominant upper limb’s external and internal rotations also presented high symmetry index values (external/internal rotation symmetry index: 33.0/34.4%) [ 49 ].…”

“…Many types of research are conducted to get empirical information about the increase of adult tennis players' stroke technique. Research about stroke generally tries to stimulate playing situations in labor conditions or find out any solution to collect experimental data in the tennis field (Lanka, Vagin, & Cicchella, 2014). Nonetheless, research still seldom tries to analyze the tennis stroke movement in detail, especially the difference between forwarding swing and the influence towards the accuracy of the stroke result, mainly towards the beginner athletes.…”

“…Thus, the efficacy of arm muscle is significant for the forehand in tennis. The efficacy of racket during the follow-through forehand phase is higher on adult players compared with kids because adult athletes have a higher factor x score that shows that they are more effective in applying the pre-stretching principle of complex tendon muscle during the backswing and forward swing phase (Lanka et al, 2014).…”
