Low physical activity in patients diagnosed with head and neck cancer.

Background: This pilot study aimed to describe physical activity (PA) and self-perceived function, health and quality of life (QoL) prior to oncological treatment in patients with head and neck cancer (HNC).

Methods: In a prospective study including 49 patients, self-perceived PA (Saltin-Grimby scale) and health-related QoL (European Organization for Research and Treatment of Cancer Quality of Life questionnaire Core 30 and EQ-5D) were assessed. Further, PA was also measured by an accelerometer attached to the thigh for eight consecutive days.

Evaluation of selected indices of gait asymmetry for the assessment of running asymmetry.

Background: The methods of running asymmetry evaluation are not as highly developed as the methods of gait evaluation.

Research Question: Which asymmetry indices used in the gait analysis best characterize the asymmetry of the running movement?

Methods: The kinematics of the sprint in a straight run over a distance of 50 m was evaluated using the X-sens system. Three indices (Ia, IS, SA) were based on discrete values from the first point of contact of the foot with the ground (1% of the running cycle phase) and were called discrete coefficients.

Effect of the Neurofeedback-EEG Training During Physical Exercise on the Range of Mental Work Performance and Individual Physiological Parameters in Swimmers.

The aim of the study was to demonstrate the effects of the Neurofeedback-EEG training during physical exercise on the improvements in mental work performance and physiological parameters. The study examined seven swimmers based on the following anthropometric measurements: body height, body mass and body composition. The Kraepelin's work curve test, EEG and EMG during physical exercise were also performed.

Postural stability pattern as an important safety factor of firefighters.

Background: Firefighting is a hazardous profession that involves high fall risk and is crucial component for the safety of people.

Objective: The aim of this study was to identify factors that impact on postural stability patterns of firefighters.

Methods: The study examined 177 Polish firefighters from the National Firefighting and Rescue System (NFRS) aged 31.
