Abstract Background Musculoskeletal (MSK) disorders represent a remarkable burden to society and an unpleasant burden for the individual. Physical activity (PA) can prevent MSK disorders while conferring other beneficial effects on health. The present study aimed to investigate associations between device-measured PA and perceived MSK disorders among young adult men. Methods Participants’ physical behavior was measured with a hip-worn accelerometer in a sample of 422 young adult Finnish men aged 26 (SD 7) years. Incidences of three common MSK disorders (knee pain, lumbar radiating pain, and lumbago pain) during the last month were inquired by a questionnaire. Binary logistic regression was used to examine the associations between the MSK outcomes and explanatory PA variables (PA times at different intensity levels, standing, and sedentary times). Age, education, smoking, BMI, and maximal oxygen uptake were controlled for in the models. Results PA and sedentary times were not significantly associated with the incidence of perceived MSK pain during the last month, except for lumbago pain. For lumbar radiating pain, the odd ratio (OR) was 1.02 (95% CI 0.96 to 1.09), and for knee pain, the OR was 1.02 (95%CI 0.96 to 1.08). Lumbago pain was more probable if the relative time spent in light PA increased, even after adjusting for potential confounding factors, including moderate-to-vigorous physical activity. However, the OR was yet small, only 1.07 (95% CI 1.02 – 1.14). Conclusions The lack of significant and clinically meaningful associations between device-measured PA and common MSK disorders observed in by young adult men was surprising and requires further confirmation.

Objectives: The present study examines the stability of Developmental Coordination Disorder (DCD) from childhood to adulthood. DCD affects around 5-6% of children and according to previous research, it is known to have connections to physical activity, fitness, cognitive ability, mental health, and other neurodevelopmental disorders. The present study examined, whether those suffering motor impairment as a child differ from typically developed in adulthood, regarding motor skills, self-reported physical activity and fitness or cognitive ability. Methods: The study participants were part of a longitudinal research project perinatal risk cohort born in 1971-1974 (PLASTICITY-project). According to motor test results at the age of 9, study participants were divided into groups: probable DCD (n=24), possible DCD (n=63) and typically developed (n=328). As a 40-year-old adult motor skills were assessed with balance test and fine motor test, physical activity and fitness with a questionnaire, and cognitive ability with Wechsler’s test (WAIS-IV). Statistical analysis were conducted using analysis of variance (ANOVA). Results and conclusions: As an adult, those with probable DCD were at a lower level with fine and gross motor skills as compared to typically developing. Regarding cognitive ability, those with motor impairment as a child scored lower on perceptual reasoning. All groups reported their physical activity to the same level, but those with childhood motor impairment estimated their cardiovascular fitness to be weaker. Motor and cognitive impairments associated with DCD appear to be permanent and level out as an adult.

Objective. Despite the health benefits of physical exercise, several adolescents exercise less than recommended and physical activity decreases from childhood to adolescence. However, there has been quite little research into the factors affecting physical activity. The circadian rhythm shifts later in adolescence, which is linked to problems with schooling, as well as psychological and physical difficulties. However, further objective research is needed of the association of circadian rhythm and physical activity in adolescence. This study examined the association of circadian period length and timing of the circadian rhythm to physical activity in adolescents and whether sex moderates these associations. Methods. The sample consisted of 262 16–19 years old adolescents (70.6 % girls) who participated in the cohort study SleepHelsinki!. Circadian period length was measured by skin temperature and timing of the circadian rhythm was measured with an actigraphs according to the midpoint of sleep, as well as with the reduced version of the MEQ survey, which measures circadian preference. Metabolic equivalents as well as the amount of sedentary behavior, light physical activity and moderate to vigorous physical activity was calculated from the actigraphy data. Relationship between circadian period length and physical activity was analyzed with linear and quadratic regression analyzes, and relationship between midpoint of sleep and physical activity with linear regression analyzes. Relationship between circadian preference and physical activity was analyzed by one-way analyzes of variance. The moderating effect of gender was examined by adding the interaction of gender and independent variable to the models. Results. Circadian period length was in a quadratic relationship to light as well as moderate to vigorous physical activity: shorter and longer than average circadian period associated with lower activity level and a near-average circadian period with higher activity level. Later sleep midpoint associated with lower metabolic equivalent, lower light and moderate to vigorous physical activity and higher sedentary time. Circadian preference was not associated with physical activity. Gender did not moderate associations. Conclusions. Adolescents whose circadian rhythm is delayed or inconsistent with the rhythm of society should be considered when planning ways to support adolescent’s physical activity, because these adolescents are at greater risk for physical inactivity and its adverse health effects. One way could be shifting school start times later, which would reduce adolescent’s social jet lag, sleep deprivation and daytime fatigue, and thus support their physical activity.
