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. The accelerometer PA was compared to the PA of a reference population assessed with the same method. Results presented are from data collected before start of oncological treatment. Results The patients (44‐79 years, 65% males) spent most of their time in sedentary behavior: a median of 555 minutes/day in bed (39% of total) and 606 minutes/day sitting (41%). Only 129 minutes/day were spent moving/walking. Patients with higher education, reduced physical function and higher fatigue were less physically active (P ≤ .01). Further, the different PA measures demonstrated a pattern of being less physically active compared to the reference population. Conclusions Patients diagnosed for HNC may have low PA level. Assessment of PA from accelerometer data may be an important component of oncological treatment to identify patients in need for PA intervention that may enhance treatment outcome.
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. The athletes followed 20 Neurofeedback-EEG training sessions on the swimming ergometer for 4 months. Most mean indices of partial measures of the work curve were significantly modified (p < 0.05) following the Neurofeedback-EEG training. Mean level of maximal oxygen uptake in study participants was over 55 ml/kg/min, with statistically significant differences documented between the first and the second measurements. No significant differences were found in the fatigue rate between the measurements 1 and 2. The improved mental work performance following the Neurofeedback-EEG training facilitates optimization of psychomotor activities.
The International Paralympic Committee mandates the development of an evidence-based classification system, which requires a measure of performance. Performance in cross-country sit-skiing is mainly dependent on force generated during the poling phase and is enhanced by trunk flexion–extension movements. Since all sit-skiers have neuromuscular impairment, but different ability to control the trunk, this study aimed to verify if simulated action of poling on an adapted ergometer, together with a cluster analysis, could be used for grouping participants with different impairments according to their performance. On the ergometer, eight male and five female participants performed seven poling cycles at maximal speed, while sitting on personal sit-ski. Based on maximal speed, generated force, cycle characteristics, and trunk kinematics, cluster analysis divided participants into three groups showing good accuracy, sensitivity, and precision. Although a validation of this exploratory study is necessary, skiing on the ergometer could be considered as sport-specific measure of performance and may become an interesting tool in the development of an evidence-based classification system for cross-country sit-skiing.
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 31.9 ± 10.1 years, with body height of 179.6 ± 5.93, body mass of 83.9 ± 11.0 and BMI of 26.0 ± 3.03. Postural stability was evaluated by means of the Balance System SD (Biodex USA) set at the level 12 of instability, in a sportswear, bunker gear, with and without visual input. The fall risk test (FRI) was also performed. Four indices were analysed: overall stability index (OSI), anterior-posterior stability index (APSI), medial-lateral stability index (MLSI), and fall risk index (FRI). RESULTS: Mean results for fall risk index (FRI) were in the normal range for all age groups regardless of the type of clothing the firefighters were wearing. Individual results obtained in the fall risk test, 128 firefighters were in the normal range for their age, furthermore, 10 firefighters obtained better results than the normal range, 34 firefighters had worse results and 5 people failed to complete the test. Postural stability with eyes closed was found to decline with age. Wearing bunker gear did not have an effect on postural stability. CONCLUSIONS: Balance tests should be integrated into the firefighting training routines in order to improve balance and support fall prevention. Exercises with reduced visual input should also be incorporated into the training methodology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
