IRCT20220713055455N1 IRCT 2022-11-03 Semnan University of Medical Sciences Comparison of the effect of whole body vibration before and after eccentric exercise on functional markers of delayed onset muscle soreness Comparison of the effect of whole body vibration before and after eccentric exercise on functional markers of delayed onset muscle soreness 2022-10-02 anticipated 48 Complete https://irct.ir/trial/65108 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Other design features: -, Randomization description: In this research, available sampling method and random grouping based on coding method will be used. The samples are coded with two-digit numbers using a random number table and randomly selected from a point of the table until the number of samples is 48, Blinding description: In this research, 48 male and female sitting volleyball athletes are studied. The initial sampling will be voluntary, but in the next stage, subjects will be randomly (systematically) selected from among those who are eligible and registered. N/A delayed onset muscle soreness. Intervention 1: Intervention group 1: Seated volleyball athletes (16 people) after warming up and stretching for 5 minutes will perform 50 outward contractions with an intensity of 85% of 1RM and then undergo vibration therapy for one minute with a frequency of 40 Hz - with peak amplitude. They will be placed up to the top of 2 mm. Intervention 2: Intervention group 2: Seated volleyball athletes (16 people) before warming up and stretching for 5 minutes will perform 50 outward contractions with an intensity of 85% of 1RM and then undergo vibration therapy for one minute with a frequency of 40 Hz - with peak amplitude. They will be placed up to the top of 2 mm. Intervention 3: Control group: The control group (16 people) - sitting volleyball athletes (16 people) will perform warm-up and stretching exercises for 5 minutes, 50 outward contractions with an intensity of 85% of 1RM, and undergo vibration therapy before and after training. are not placed.

Timepoint: All measurements will be done before, immediately after, 24, 48 and 72 hours and one week and two weeks after the implementation of the protocol. Method of measurement: To measure isometric (static) strength, the examinee holds the dynamometer in one hand so that the hand is in line with the arm and hangs next to the thigh. Without moving his hand, he displays his maximum power by pressing the dynamometer. This movement should be repeated 2 times. Range of motion of the non-dominant elbow. Timepoint: All measurements will be done before, immediately after, 24, 48 and 72 hours and one week and two weeks after the implementation of the protocol. Method of measurement: The goniometer will be used to measure the range of motion. To measure the range of motion, the fixed arm of the goniometer will be placed parallel to the acromion-radial line and the movable arm of the goniometer will be placed on the radial-ulnar line in anatomical position. Circumference of the non-dominant arm. Timepoint: All measurements will be done before, immediately after, 24, 48 and 72 hours and one week and two weeks after the implementation of the protocol. Method of measurement: A tape measure is used to measure the circumference of the arm. To measure the circumference of the arm, first, the middle point of the acromion-radial line is determined, then the person places his hand in a hanging position next to the body, and the circumference of the arm is at the mentioned point. It will be measured perpendicular to the length of the arm. Muscle contusion(visual analogue scale). Timepoint: All measurements will be done before, immediately after, 24, 48 and 72 hours and one week and two weeks after the implementation of the protocol. Method of measurement: In order to measure muscle contusion, a visual perception chart will be used. This chart contains 10 grades, zero indicates the absence of pain, and grade 5 indicates pain that is caused by movement and causes little restriction. Grade 10 also indicates pain that may prevent any movement.
