To total amount of activity. And beyond: Perspectives on measuring physical behavior
The aim of this paper is to describe and discuss some perspectives on definitions, constructs, and outcome parameters of physical behavior. The paper focuses on the following constructs: Physical activity and active lifestyle vs. sedentary behavior and sedentary lifestyle; Amount of physical activity vs. amount of walking; Detailed body posture and movement data vs. overall physical activity data; Behavioral context of activities; Quantity vs. quality; Physical behavior vs. physiological response. Subsequently, the following outcome parameters provided by data reduction procedures are discussed: Distribution of length of bouts; Variability in bout length; Time window; Intensity and intensity threshold. The overview indicates that physical behavior is a multi-dimensional construct, and it stresses the importance and relevance of constructs and parameters other than total amount of physical activity. It is concluded that the challenge for the future will be to determine which parameters are most relevant, valid and responsive. This is a matter for physical behavior researchers to consider, that is critical to multi-disciplinary collaboration
Health-related physical fitness of adolescents and young adults with myelomeningocele
To assess components of health-related physical fitness in adolescents and young adults with myelomeningocele (MMC), and to study relations between aerobic capacity and other health-related physical fitness components. This cross-sectional study included 50 adolescents and young adults with MMC, aged 16-30 years (25 males). Aerobic capacity was quantified by measuring peak oxygen uptake (peakVO(2)) during a maximal exercise test on a cycle or arm ergometer depending on the main mode of ambulation. Muscle strength of upper and lower extremity muscles was assessed using a hand-held dynamometer. Regarding flexibility, we assessed mobility of hip, knee and ankle joints. Body composition was assessed by measuring thickness of four skin-folds. Relations were studied using linear regression analyses. Average peakVO(2) was 1.48 +/- 0.52 l/min, 61% of the participants had subnormal muscle strength, 61% had mobility restrictions in at least one joint and average sum of four skin-folds was 74.8 +/- 38.8 mm. PeakVO(2) was significantly related to gender, ambulatory status and muscle strength, explaining 55% of its variance. Adolescents and young adults with MMC have poor health-related physical fitness. Gender and ambulatory status are important determinants of peakVO(2). In addition, we found a small, but significant relationship between peakVO(2) and muscle strength
Exercise self-efficacy in persons with spinal cord injury: psychometric properties of the Dutch translation of the exercise self efficacy scale
Patients who do not complete cardiac rehabilitation have an increased risk of cardiovascular events during long-term follow-up
Inactive and sedentary lifestyles amongst ambulatory adolescents and young adults with cerebral palsy
Background: To assess physical behaviour, including physical activity and sedentary behaviour, of ambulatory adolescents and young adults with cerebral palsy (CP). We compared participant physical behaviour to that of able-bodied persons and assessed differences related to Gross Motor Functioning Classification System (GMFCS) level and CP distribution (unilateral/bilateral). Methods. In 48 ambulatory persons aged 16 to 24 years with spastic CP and in 32 able-bodied controls, physical behaviour was objectively determined with an accelerometer-based activity monitor. Total duration, intensity and type of physical activity were assessed and sedentary time was determined (lying and sitting). Furthermore, distribution of walking bouts and sitting bouts was specified. Results: Adolescents and young adults with CP spent 8.6% of 24 hours physically active and 79.5% sedentary, corresponding with respectively 123 minutes and 1147 minutes per 24 hours. Compared to able-bodie
Cardiac rehabilitation for patients with obesity:lessons learned from the OPTICARE XL trial
Obesity is a known and commonly encountered risk factor for the development of cardiac diseases. Patients with cardiac diseases who also have obesity do not benefit optimally from standard cardiac rehabilitation (CR) programs. Exercises performed during CR are not the best fit for patients with obesity and counselling sessions often do not address their specific needs. OPTICARE XL is the first large multicentre randomised controlled trial to investigate the added value of a dedicated one-year CR program specifically designed for patients with obesity and integrated in daily practice. The short-term effects on body weight and physical activity were promising and patients with obesity experienced the program as highly desirable. However, the OPTICARE XL CR program did not show long-term added value compared with standard CR on health-related quality of life, psychosocial well-being, body weight, physical activity and physical fitness, nor on costs. The current article offers an overview of the background of this trial and discusses the most important results of the OPTICARE XL trial and the reasons behind the unanticipated long-term outcomes. Furthermore, it offers recommendations for future research and how to redesign the OPTICARE XL CR program to expand the short-term results.</p
Functional Independence and Health-related Functional Status Following Spinal Cord Injury:A Prospective Study of the Association with Physical Capacity
Objective: To determine changes in functional independence following spinal cord injury and to evaluate the association between functional independence and physical capacity. Design: Multi-centre prospective cohort study.Subjects: Patients with spinal cord injury admitted for initial rehabilitation.Methods: The motor Functional Independence Measure (FIMmotor) was determined at the start of rehabilitation (n = 176), 3 months later (n = 124), at discharge (n = 160) and one year after discharge from inpatient rehabilitation (n = 133). One year after discharge, physical and social dimensions of health-related functional status (Sickness Impact Profile 68; SIP68) were determined. On each occasion, physical capacity was established by measuring arm muscle strength, peak power output and peak oxygen uptake.Results: Multi-level random coefficient analyses revealed that FIMmotor improved during inpatient rehabilitation, but stabilized thereafter. Changes in FIMmotor were associated with peak power output. Multiple regression models showed that FIMmotor and peak power output at discharge were associated with FIMmotor one year after discharge (R-2 = 0.85), and that peak power output at discharge was associated with the social dimension of the SIP68 (R-2 = 0.18) one year after discharge.Conclusion: Functional independence improves during inpatient rehabilitation, and functional independence is positively associated with peak power output
