Title: The Comparison of Muscle Timing of Chosen Shoulder Girdle Muscles During Breaststroke Inside and Outside the Water Objectives: The aim of this thesis was to compare timing and activation of chosen shoulder girdle muscles during breaststroke in the pool with counterflow and during excercise with rubber expander. Methods: It was analyzed timing and level of muscle activation during swimming and simulating the same movement of upper extremities in the air against the power of rubber expander. As an objetification was used surface electromyography. One profesional swimer took part in this experiment Results: Based on results it seemed that the movement of upper extremities are different in the pool and in the air during swimming stroke of breaststroke. Most of the measurement were different in the pool and in the air. Keywords: swimming, breaststroke, EMG, WaS-EMG, electromyography, shoulder girdle muscles, timing

Author: Bc. Modinat Sanni Supervisor: Ing. Miroslav Vilímek, PhD Title: MUSCLES ACTIVATION DURING "SHOULDER MOUNT"POLE ACROBATIC EXERCISE Purpose: This study is an empirical - theoretical study presents the literature review regarding to the topic of the shoulder function anatomy, kinesiology, biomechanics, non-traumatic injuries of the shoulder and their prevention by using the available literatures. Further, the study also compares by surface electromyography the amplitudes, shapes and durations of myoelectric signals of m. latissimus dorsi, m. pectoralis maior, m. biceps brachii, m. infraspinatus and m. supraspinatus of dominant shoulder in two healthy individuals during acrobatic exercise on vertical pole known as "Shoulder Mount". The purpose was monitor the changes in two different conditions; i.e. kinesiotape and elbow brace and compare with the control condition for the reason of finding out their ability to affect the myoelectric activities of selected muscles. Further, the Shoulder Mount exercise had recorded by six Qualisys cameras for motion analyses. Methods and materials: The potentially eligible scientific articles perform a search of studies on the topic of kinesiotapes and tennis elbow brace as measured by EMG mainly on myoelectric activity of the shoulder complex were seared from...

We watched activity of ten selected muscles during canoe forward stroke, on simulator, diagonal pull, stretch of arms with elastic resistance, dumbbell pulls and pull ups by surface electromyography. Study evaluates intraindividual and subsequently interindividual the size of the muscle activation considering reference movement, forward stroke on flat water. The results proved similarities of the forward stroke and on simulator in terms of average muscle activation. M. latissimus dorsi shows higher activation during canoe forward stroke, on simulator, stretch of arms with elastic resistance, dumbbell pulls compared with other tested exercices. locomotion through the shoulder girdle, shot, canoeing, paddling, electromyography, muscular activity

The aim of this study is to evaluate the effect of dynamic stabilizing strategy on handgrip and pinchgrip strength. Exercise utilized in this study was based on rehabilitative approach called Dynamic Neuromuscular Stabilization (DNS) - a developmental kinesiology approach. The exercise program consisted of four primal developmental positions (3½ month supine position, oblique sitting position with support on forearm, position on all fours, and the "bear" position). A study file consisted of ten females who were instructed in basic scheme of DNS exercise. They were instructed to exercise at home five times weekly for a 6- weeks period. One exercise lesson took about thirty minutes. Both handgrip and pinchgrip strength was measured using the digital dynamometer CITEC CT 3001 recording maximum voluntary isometric contraction (MVIC). Three-pinch grip strength and fist grip strength was measured for both upper extremities. Fist grip strength was measured in three positions of forearm (pronation, supination and neutral position). Overall eight variables (for each extremity, grip form and position of the forearm) measured before and after exercise program were compared using the paired t-test. Significant increase in muscle strength (p<0,05) was identified for all eight variables after a 6 weeks exercise...
