Background. The main aim of our research was to determine if there was a relationship between prefrontal cortex activity during Stroop test (dependent variables) and variables of “Go/NoGo”, Balloon Analogue Risk Task, impulsivity score, different tests of cognitive functions, moral decisions tests (altruistic or egoistic), Fitts-like motor control task, five character traits, emotional intelligence, mood, sleepiness and perceived stress, total physical activity of subjects (independent variables). Methods.In total, 20 undergraduate students (mean age were 21.3, SD = 1) met the criteria and agreed to participate in this study. Results. Our research has shown that different brain functional outcomes, that is speed-accuracy motor control, inhibition response control and cognitive performance, risky-taking behaviour and impulsivity control, management of emotion, personality consciousness and physical activity have a common correlation with the increase in prefrontal cortex activity (measured by fNIRS) during Stroop test. Conclusion. Our studies have clearly shown that different brain functional outcomes, that is speed-accuracy motor control, inhibition response control and cognitive performance, risky-taking behaviour and impulsivity control, management of emotion, personality consciousness and physical activity have a common correlation with the increase in prefrontal cortex activity (measured by fNIRS) during Stroop test. Considerable number of studies are needed to understand what is the functional essence of these relationships, but currently there is an increase of research establishing correlations between motor behaviour and cognition control.

Objective.This study examined the association between obstructive sleep apnea (OSA), daytime sleepiness, functional activity, and objective physical activity.Setting.Subjects (N=37) being evaluated for OSA were recruited from a sleep clinic.Participants. The sample was balanced by gender (53% male), middle-aged, primarily White, and overweight or obese with a mean BMI of 33.98 (SD=7.35;median BMI=32.30). Over 40% reported subjective sleepiness (Epworth Sleepiness Scale (ESS) ≥10) and had OSA (78% with apnea + hypopnea index (AHI) ≥5/hr).Measurements.Evaluation included questionnaires to evaluate subjective sleepiness (Epworth Sleepiness Scale (ESS)) and functional outcomes (Functional Outcomes of Sleep Questionnaire (FOSQ)), an activity monitor, and an overnight sleep study to determine OSA severity.Results.Increased subjective sleepiness was significantly associated with lower scores on the FOSQ but not with average number of steps walked per day. A multiple regression analysis showed that higher AHI values were significantly associated with lower average number of steps walked per day after controlling patient's age, sex, and ESS.Conclusion.Subjective sleepiness was associated with perceived difficulty in activity but not with objectively measured activity. However, OSA severity was associated with decreased objective physical activity in aging adults.

Background: Prostate cancer (PCa) represents a common disease in men aged >65 years. The role of physical activity (PA) in patients at risk or diagnosed with PCa represents an evolving issue. We aimed to summarize available evidences about the impact of PA on the pathophysiology and clinical outcomes of PCa. Methods: We performed a narrative review. Evidences about the role of PA in elderly patients in terms of PCa biology, epidemiology, oncological and functional outcomes, as well as in terms of impact on the outcomes of androgen deprivation therapy (ADT) were summarized. Results: Potential pathophysiological pathways hypothesized to explain the benefits of PA in terms of prostate carcinogenesis include circulating levels of Insulin-like growth factor-1 (IGF-1), oxidative stress, systemic inflammation, sex hormones, and myokines. Clinically, emerging evidences support the hypothesis that PA is associated with decreased PCa risk, improved PCa-related survival, improved functional outcomes, and reduced ADT-related adverse events.

Background. Physical activity is beneficial for improving cognitive function in healthy older adults. However, research results on the benefits of physical activity on cognitive performance after stroke are limited. Objective. To determine if a combined exercise and recreation program can improve the executive functioning and memory of individuals with chronic stroke. Methods. In all, 11 ambulatory participants with chronic stroke (mean age 67 ± 10.8 years) participated in a 6-month program of exercise for 2 hours and recreation for 1 hour weekly. Executive functions and memory were assessed at baseline and at 3 and 6 months by a battery of standard neuropsychological tests, including response inhibition, cognitive flexibility, dual task (motor plus cognitive), and memory. Motor ability was also assessed. Nonparametric statistics were used to obtain the differences between the 3 assessments. Results . At baseline, substantial deficits in all aspects of executive functioning were revealed. From baseline to 3 months, the mean improvement was 10% ± 14% for the dual task (Walking While Talking), -3% ± 22% (χ 2 = 2.4; P > .05) for response inhibition (Stroop Test), and 61% ± 69% for memory (Rey Auditory Verbal Learning Test—long delay). From baseline to 6 months, the mean improvement was 7% ± 7.5% for response inhibition (Stroop Test). In addition, knee strength and walking speed improved significantly at 3 months. Conclusions. This pilot study suggests that exercise and recreation may improve memory and executive functions of community-dwelling individuals with stroke. Further studies require a larger sample size and a control group.

The Brain

To divide the types of aging (successful, usual and impaired), as well as factors affecting this process, the protective role of physical activity was discussed in the literature. It was emphasized that physical activity is also a very important protective factor for cognitive aging - mainly executive function and memory. The prefrontal cortex and hippocampus, i.e. the regions of the brain responsible for the control and course of cognitive processes, show susceptibility to stimulation, which is movement exercises, which are prevention of degenerative changes within the brain.
