• Resumen

  • The rotator cuff is a group of muscles and tendons that act to stabilize the human shoulder and allow for its extensive range of motion. This study aimed to compare the immediate effect and durability of mobilization and oscillation dumbbell (OD) training on the Joint Position Sense (JPS) and strength of rotator cuff muscles in young tennis players. Twenty-six tennis players were divided into two experimental groups. G1 only performed mobilization techniques while G2 only performed OD training, before, after and after one week of the protocols, the strength and JPS of the shoulder joint were measured with an isokinetic dynamometer. Repeated analysis of variance (RMANOVA) and Bonferroni post hoc test were used to examine the differences between the groups. The analysis of covariance was used to examine the differences between the groups. In general, the results showed a significant effect of both mobilization techniques and OD training programs on the JPS and internal and external rotation strength of young tennis players, but only one difference was observed between the two in external rotation for the eccentric/concentric action at 120°/sec (p=0009; ƞ2p= 0.32). Moreover, the main findings showed that mobilization techniques and OD improved internal and external rotations after the protocol and after one week when compared with baseline for the concentric/concentric and eccentric/concentric at 60°/sec and 120°/sec (p < 0.05) with only one exception for the internal rotation concentric/concentric at 120°/sec for both groups (p > 0.05). Based on this, it seems that in healthy tennis players, both one-session mobilization techniques and OD training can be used to improve JPS and strength. [ABSTRACT FROM AUTHOR]
