Comparison of the Effect of Corrective Exercises with and without Vibration on Range of Motion in the Frontal Plate in Female Badminton Players

The aim of this study is to compare the effect of corrective exercises with and without vibration on range of motion in the frontal plate in female Badminton players. The subjects of this quasi-experimental study included 36 female badminton players with neck and shoulder deformities in Karaj city who participated in this study in a purposeful manner and were randomly divided into three identical groups of 12 corrective exercises, corrective exercises with vibration and control. Preliminary evaluation of shoulder deformity was performed using a manual inclinometer. To evaluate the range of motion of the shoulder and neck joints, a clinometer application that can be installed on iPhones was used. The correction training protocol included an 8-week neck and shoulder correction training program according to the NASM approach using (myofascial release, lengthening, activation, cohesion and integration). The second experimental group, in addition to corrective exercises, also had vibration intervention. Correction exercises (supplementation) were performed with vibration in two parts: flexibility and strength. Flexibility exercises were performed at the beginning of the session with a frequency of five to 18 Hz and a range of two to four millimeters. In contrast, strength training had a frequency (eventually) of 50 Hz, and the person trained on the machine for a maximum of two minutes. Complementary vibration exercises were performed in three to four sets of two minutes (maximum), with a rest of 60 to 90 seconds. Hypotheses were analyzed using one-way analysis of variance and Tukey post-hoc test. The results showed that corrective exercises with and without vibration increased the range of motion of the neck and shoulder joints of female badminton players in the frontal plate, but there was a significant difference between the effects of corrective exercises with and without vibration on the range of motion of the frontal plate in female badminton players
