(author), PRECOVID-study group, (author)Background. Vitamin D deficiency is frequently found in patients with chronic obstructive pulmonary disease (COPD). Vitamin D has antimicrobial, anti-inflammatory, and immunomodulatory effects. Therefore, supplementation may prevent COPD exacerbations, particularly in deficient patients. Objectives. We aimed to assess the effect of vitamin D...article 2022

(author)Objectives: Physical activity in people with dementia (PwD) may enhance physical and mental functioning. Exergaming, which combines physical exercise with cognitive stimulation in a gaming environment, was developed to overcome barriers in performing physical activities. We evaluated the effects of exergaming in day care centers (DCCs) for PwD...article 2021

(author), Veeger, N.J.G.M. (author), van der Leij, F.R. (author), Keijer, J. (author)This study tested the hypothesis that in human aging, a decreased intramuscular acylcarnitine status is associated with (pre-)frailty, reduced physical performance, and altered mitochondrial function. We used a cross-sectional study design with well-matched fit and (pre-)frail old males and females, using young males and females as healthy...article 2020

(author), Wiersinga, J. (author), van Straten, A. (author)Background Physical activity is linked to benefits such as increased physical fitness, cognition, emotional and social functioning, general health and well-being in older people. Some evidence suggests that this also applies to people living with dementia. However, it can be harder for them to perform physical activities, due to several barriers...article 2019

(author)Background: Identification of older persons at risk for the loss of independence, onset of (co)-morbidity or functional limitations through screening/assessment is of interest for the public health-care system. To date several different measurement instruments for overall physical function are frequently used in practice, but little information...article 2012

(author)Background and aims: The Assessment of Daily Activity Performance (ADAP) test was developed, and modeled after the Continuous-scale Physical Functional Performance (CS-PFP) test, to provide a quantitative assessment of older adults' physical functional performance. The aim of this study was to determine the intra-examiner reliability and...article 2006

Westhoff, M.H. (author), Stemmerik, L. (author), Boshuizen, H.C. (author), TNO Preventie en Gezondheid (author)This study's purpose was to investigate whether a 10-week low-intensity strength-training program could improve strength of the knee extensors and functional ability. Participants 65 years and older with low knee-extensor muscle strength were randomized into an exercise (n = 11) and a control group (n = 10). Knee-extensor strength and functional...article 2000
