“…When investigating the relationship between physical activity and health it is necessary to measure daily physical activity [7]. Accelerometers have been widely accepted as useful objective measurement tools of daily physical activity [8]. Daily physical activity outcomes measured using accelerometer-based activity monitors include steps per day and time spent standing.…”

Purpose: To examine if individualised resistance training increases the daily physical activity of adolescents and young adults with bilateral spastic cerebral palsy (CP).Method: Young people with bilateral spastic CP were randomly assigned to intervention or to usual care. The intervention group completed an individualised lower limb progressive resistance training programme twice a week for 12 weeks in community gymnasiums. The primary outcome was daily physical activity ( number of steps, and time sitting and lying). Secondary outcomes included muscle strength measured with a one-repetition maximum (1RM) leg press and reverse leg press. Outcomes were measured at baseline, 12 weeks, and 24 weeks. Results:From the 36 participants with complete data at 12 weeks there were no between-group differences for any measure of daily physical activity. There was a likely increase in leg press strength in favour of the intervention group (mean difference 11.8 kg; 95%CI: -1.4 to 25.0). No significant adverse events occurred during training. Conclusions:A short-term resistance training programme that may increase leg muscle strength was not effective in increasing daily physical activity. Other strategies are needed to address the low daily physical activity levels of young people with bilateral spastic CP.3

“…This may include the monitoring of physical activity (Shammas et al, 2014;Yang & Hsu, 2010) and cardiac output (Pickering, Shimbo, & Haas, 2006), as well as collecting saliva samples for endocrine markers (Schlotz, 2012). The role of cortisol as a potential mediator of any association between psychological stress and fatigue in MS provides a potential avenue for future research incorporating ambulatory assessment.…”

Zusammenfassung AbstractNeuropsychological disorders involve a variety of symptoms that often lead to substantial functional impairments in daily life. Research, assessment, and treatment should include a reference to daily life, considering symptoms, personality, and life circumstances of the individual patient. Ambulatory assessment methodology provides progress by avoiding retrospective memory-based bias, increasing ecological validity, and by generating individual time series that permit idiographic analysis. Using multiple sclerosis as an example, we illustrate new findings generated by ambulatory assessment studies in the areas of fatigue, stress and cognitive functions, and we demonstrate future opportunities presented by ambulatory assessment methodology to research and clinical practice with multiple sclerosis patients.

“…Thresholds for activity counts per minute (CPM) (Troiano et al 2008;Tudor-Locke et al 2012) have been created to correspond to Metabolic Equivalents (MET) for moderate (3-6 MET), and vigorous (>6 MET) intensities of PA . However, using the same (guideline) CPM intensity threshold values across a heterogeneous population may bias accelerometer measured PA against individuals with greater body mass as they will expend more energy during PA at the same acceleration compared to individuals with a lower body mass (Newton's second law: Force= mass·acceleration) (Yang and Hsu 2010).…”

Objective: To explore whether accelerometer thresholds that are adjusted to account for differences in body mass influence discrepancies between self-report and accelerometer measured physical activity (PA) volume for individuals with overweight and obesity.Methods: 6164 adults from 2003-2006 NHANES surveys were analyzed. Established accelerometer thresholds were adjusted to account for differences in body mass to produce a similar energy expenditure (EE) rate as individuals with normal weight. Moderate, vigorous, and moderate-to-vigorous (MV) intensity PA durations were measured using established and adjusted accelerometer thresholds and compared to self-report.Results: Durations of self-report were longer than accelerometer measured MVPA using established thresholds (normal weight: 57.8±2.4 vs 9.0±0.5 min/day, overweight: 56.1±2.7 vs 7.4±0.5 min/day, and obesity: 46.5±2.2 vs 3.7±0.3 min/day). Durations of subjective and objective PA were negatively associated with body mass index (BMI) (P<0.05). Using adjusted thresholds increased MVPA durations, and reduced discrepancies between accelerometer and self-report measures for overweight and obese groups by 6.0±0.3 min/day and 17.7±0.8 min/day, respectively (P<0.05). Conclusion:Using accelerometer thresholds that represent equal EE rates across BMI categories reduced the discrepancies between durations of subjective and objective PA for overweight and obese groups. However, accelerometer measured PA generally remained shorter than durations of self-report within all BMI categories. Further research may be necessary to improve analytical approaches when using objective measures of PA for individuals with overweight or obesity.
