KRATKY, Jakub. Monitoring the activation of selected muscle groups of clients with spinal cord injuries. Prague: Charles University, Faculty of Physical Education and Sport, 2013. 82 pages. Supervisor Doc. PaedDr. Karel Jelen, CSc The aim of this thesis is to monitor the activation of selected muscle groups (musculus deltoideus pars anterior, musculus deltoideus pars posterior, musculus triceps brachii caput laterale and musculus trapezius pars descendus) during double poling ergometry. Nine subjects with different spinal cord lesions volunteered to participate in the study. The surface electromyography is used to detect the musculus activation. The monitoring of four muscle groups is devided into three phases. Firstly, all the participants double-poled for one minute at moderate intensity according to the Borg scale. Each participant underwent a 10-minute intervention to correct the posture. In the last phase the volunteers exercised again for one minute at moderate intensity. The aim of the intervention is to decrease muscle activation of musculus deltoideus pars anterior and musculus trapezius pars descendus (muscles with a tendency to hypertonia during wheelchair propulsion and activity of daily living) and to increase muscle activation of musculus deltoideus pars posterior and musculus triceps..
