Dual Tasking

Although sleep quality disorders can have a negative effect on postural control, studies about this subject are scarce. The aim of this study is to assess the differences in standing posture performance during dual tasking between healthy young adults with a good and poor sleep quality. Thirty-five healthy participants (23.09 ± 3.97 years) performed a postural task (standing posture single task ((ST)) and a dual task (DT): quiet standing while performing a concurrent cognitive task, while the total excursion of the center of pressure (TOTEX CoP), the displacement anterior–posterior (CoP-AP) and medial–lateral (CoP-ML), the mean total velocity displacement of CoP (MVELO CoP) and ellipse sway area (CEA) were measured with a force plate. After assessing the sleep quality with the Pittsburgh Sleep Quality Index, they were divided into two groups (good ((n = 21)) and poor ((n = 14)) sleep quality) to establish comparisons. This study revealed no significant differences in TOTEX CoP, CoP-ML, CoP-AP, MVELO CoP, and CEA among both sleep quality groups. In conclusion, differences in the sleep quality (good or poor sleep quality) among young adults appear not to be a relevant factor in the CoP variation, but the DT versus ST can compromise postural control performance independently of the sleep quality.

Abstract Background Previous studies suggest that poor sleep quality negatively affects the executive function of the prefrontal cortex and, consequently, the impairment of learning abilities. The aim of this study was to compare the oxygenated hemoglobin concentration ([HbO2]) during cognitive dual-task with subjective sleep quality in young adults. Methods Thirty-two healthy young adults (age = 23.13 ± 3.92 years, mean ± SD) were recruited according to the eligibility criteria. Using functional near-infrared spectroscopy (fNIR), oxygenated hemoglobin concentration ([HbO2]) was measured during quiet standing while performing a concurrent cognitive task - arithmetic and memory tasks (cognitive dual-task). The quality of sleep was assessed by the Pittsburgh Sleep Quality Index (PSQI). After data processing, the Mann-Whitney test was used for comparison and the statistical significance level was set to P < 0.05. Results There were 59.4% of participants with a global PSQI score ≤5 (good sleep quality) and 40.6% with a score > 5 (poor sleep quality). No differences were observed in the mean of [HbO2] in prefrontal cortex during cognitive dual-task in young adults with good and poor sleep quality (P > 0.05). Conclusions The results of this study do not support the possibility of increases in the hemodynamic response on the prefrontal cortex be expected due to a good sleep, once the sleep quality appears not to have a significant effect on [HbO2] in young adults during the performance of cognitive dual-task.

ObjectivesThe main purpose of the present study was to explore the associations between sleep quality and insufficient physical activity.DesignCross-sectional.SettingFaculties in Croatia.Participants2100 university students (1049 men and 1051 women) aged 18–24 years were recruited.Primary outcomeTo assess the domains of sleep quality (independent variables) and ‘insufficient’ physical activity (dependent variable), we used previously validated Pittsburgh Sleep Quality Index and International Physical Activity questionnaires. Logistic regressions were used to calculate the associations between the sleep quality and ‘insufficient’ physical activity.ResultsWhen sleep quality domains were entered separately into the model, very bad subjective sleep quality (OR 3.09; 95% CI 1.50 to 6.56), >60 min of sleep latency (OR 2.17; 95% CI 1.39 to 3.39), <7 hours of sleep (OR 1.56; 95% CI 1.24 to 1.96), <65% of habitual sleep efficiency (OR 2.26; 95% CI 1.26 to 4.05), sleep disturbances >1/week (OR 1.61; 95% CI 1.03 to 2.52), use of sleep medication >1/week (OR 3.35; 95% CI 1.83 to 6.10), very big daytime dysfunction problem (OR 2.78; 95% CI 1.57 to 4.93) and poor sleep quality (1.53; 95% CI 1.23 to 1.91) were associated with ‘insufficient’ physical activity. When all sleep quality domains were entered simultaneously into the model, the same significant associations remained, except for sleep disturbances. Both models were adjusted for gender, body mass index, self-rated health, life satisfaction, socioeconomic status, presence or absence of chronic diseases, smoking status, binge drinking and psychological distress.ConclusionsOur results show that ‘poor’ sleep quality is associated with ‘insufficient’ physical activity in young adults. In order to improve, special strategies and policies that leverage ‘good sleep’ quality are warranted.

The aim of this study was to investigate the effects of ankle and hip muscle fatigue on motor adjustments (experiment 1) and symmetry (experiment 2) of postural control during a quiet standing task. Twenty-three young adults performed a bipedal postural task on separate force platforms, before and after a bilateral ankle and hip muscle fatigue protocol (randomized). Ankle and hip muscles were fatigued separately using a standing calf raise protocol (ankle fatigue) on a step and flexion and extension of the hip (hip fatigue) sitting on a chair, at a controlled movement frequency (0.5Hz), respectively. In both experiments, force, center of pressure, and electromyography parameters were measured. The symmetry index was used in experiment 2 to analyze the postural asymmetry in the parameters. Our main findings showed that muscle fatigue impaired postural stability, regardless of the fatigued muscle region (i.e., ankle or hip). In addition, young adults used an ankle motor strategy (experiment 1) before and after both the ankle and hip muscle fatigue protocols. Moreover, we found increased asymmetry between the lower limbs (experiment 2) during the quiet standing task after muscle fatigue. Thus, we can conclude that the postural motor strategy is not muscle fatigue joint-dependent and a fatigue task increases postural asymmetry, regardless of the fatigued region (hip or ankle). These findings could be applied in sports training and rehabilitation programs with the objective of reducing the fatigue effects on asymmetry and improving balance.

AbstractIntroductionUnderstanding health behaviors, such as sleep and dietary patterns, is important for health promotion and disease prevention. College period is a complicated, difficult time to maintain healthy behaviors. In this regard, little is known about the impact of sleep and diet quality on well-being among college young adults. Hence, we aimed to study the impact of sleep and diet quality on well-being in college students.Materials and MethodsThree hundred-twelve Mexican college students (82% females; 20.6 ± 3.4years) were included in a cross-sectional study. Participants completed the following validated questionnaires: Well-being Index to assess well-being (high scores indicate high well-being), Pittsburg Sleep Quality Index for sleep quality (scores > 5 indicate poor sleep quality), and a validate version of the Health Eating Index for Mexican population to assess diet quality (scores > 80 indicate good diet quality). BMI and physical activity were also assessed. Scores were treated as continuous variables, and statistical analysis were performed using SPSS v24 and adjusted for confounding variables.ResultsSixty-seven percent of our population showed a poor sleep quality and eighty-four percent needs to make changes in their diet in order to improve its quality. On the other hand, fifty-one percent of the studied population had a low well-being perception. Poor sleep quality (p < 0.001) and low diet quality (p < 0.001) associated with a lower well-being perception. In addition, poor sleep quality is associated with low diet quality (p < 0.05). Regarding food consumption, higher sweets (p < 0.001) and soft-drink (p < 0.001) intake was inversely associated with well-being scores. Likewise, high consumption of sweets (p < 0.05) and soft-drink (p < 0.05), and low fruit (p < 0.05) and cereal (p < 0.05) consumption are linked to poor sleep quality.DiscussionOur results show that half of the studied population had a low well-being, and also that poor sleep and diet quality are frequent among college students. Interestingly, the fact that poor sleep and diet quality were associated to a lower perception of well-being highlights the importance of promoting sleep hygiene and diet quality among college students as an important strategy to improve well-being and health, even in young adults. In addition, we found that higher sweets and soft-drink consumption were associated to both low well-being perception and poor sleep quality. Hence, it is important to promote healthy habits regarding eating and sleeping well, in order to improve well-being perception among college students.

AbstractIntroductionFood intake behavior is implicated in many chronic health issues, including obesity. Thus, understanding the underlying factors that affect food intake is important. Several studies have associated sleep restriction to increased dietary intake and poor food choices, which can be driven by hedonic mechanisms, specially food palatability. Given that people eat for different reasons other than stress, including boredom, anxiety, sadness or joy, our aim was to study the potential association between sleep quality and the cognitive-behavioral nature of food intake (eating behaviors, EB), as well as their impact on body mass index in a population of young adults.Materials and MethodsOne thousand twenty eight young adults (78% females; 21.4 ± 4.1years) were included in a cross-sectional study. The following questionnaires were used: Pittsburg Sleep Quality Index to assess sleep quality (scores > 5 indicate poor sleep quality), the Three Factor Eating Questionnaire to assess the three dimensions of EB (emotional, uncontrolled and restraint eating) (Higher scores indicate higher EB). Additionally, height, weight, body mass index (BMI) and the level of physical activity were evaluated. Statistical analysis were performed using SPSS v24, and adjusted for confounding variables.ResultsSixty one percent of the studied population had a poor sleep quality, whereas no significant associations were found between poor sleep quality, gender or age. Poor sleep quality was associated with uncontrolled (p < 0.001) and emotional (p < 0.001) eating, as well as with BMI (p < 0.001). In addition, emotional eating was associated to BMI (p < 0.001). Finally, linear regression model showed that BMI is associated with poor sleep quality (p < 0.01) and emotional eating (p < 0.001).DiscussionOur findings suggest that poor sleep quality is frequent among young adults. Furthermore, poor sleep quality is associated with higher emotional and uncontrolled eating, showing that poor sleep might be associated with a higher tendency to over eat when coping to emotionally negative emotions (sadness, anger, depression, anxiety), and a high tendency to lose control over food intake itself. Finally, the association between poor sleep quality and high emotional eating can have a negative impact over BMI, even in young adults. Hence, interventions designed to improve weight status would benefit from focusing on sleep quality in order to reduce emotional and uncontrolled eating.

The execution of cognitive tasks is known to alter postural sway during standing, but the underlying mechanisms are still debated. This study investigated how performing a mental task modified balance control during standing. We required 15 healthy adult males to maintain an upright stance under conditions of simply relaxing and maintaining normal quiet standing (control condition) or while performing a secondary cognitive task (mental arithmetic). Under each condition, we measured the participants’ center of pressure and used kinematic measurements for a quantitative evaluation of postural control modulation. We calculated the standard deviation of the joint angles (ankle, knee, and hip) and the estimated joint stiffness to measure joint mobility changes in postural control. To estimate the kinematic pattern of covariation among these joints, we used uncontrolled manifold analysis, an assessment of the strength of multijoint coordination. Compared to normal standing, executing the cognitive task while standing led to reduced movements of the ankle and hip joints. There were no significant differences in ankle stiffness or uncontrolled manifold ratios between the conditions. Our results suggest that when performing a secondary cognitive task during standing, neither changes in the modification of stiffness nor the strength of multijoint coordination (both of which preserve the center of mass position) explains changes in postural sway.

Background and Objectives. Cognitive complaints are common in fibromyalgia (FM) and chronic fatigue syndrome (CFS). Fatigue as well as pain may require greater effort to perform cognitive tasks, thereby increasing the load on processing in the central nervous system and interfering with motor control.Methods. The effect of a concurrent arithmetic cognitive task on postural control during quiet standing was investigated in 75 women (aged 19–49 years) and compared between FM, CFS, and matched controls (n=25/group). Quiet standing on a force plate was performed for 60 s/condition, with and without a concurrent cognitive task. The center of pressure data was decomposed into a slow component and a fast component representing postural sway and adjusting ankle torque.Results. Compared to controls, CFS and FM displayed lower frequency in the slow component (p<0.001), and CFS displayed greater amplitude in the slow (p=0.038andp=0.018) and fast (p=0.045) components. There were no interactions indicating different responses to the added cognitive task between any of the three groups.Conclusion. Patients displayed insufficient postural control across both conditions, while the concurrent cognitive task did not perturb quiet standing. Fatigue but not pain correlated with postural control variables.
