Compendium of Physical Activities Strongly Underestimates the Oxygen Cost During Activities of Daily Living in Stroke Patients.
American journal of physical medicine & rehabilitation, 2019Co-Authors: Maxence Compagnat, Stéphane Mandigout, Romain David, Justine Lacroix, Jean-christophe Daviet, Jean Yves SalleAbstract:Objective The aim of the study was to measure the Metabolic Equivalent task when performing physical activities of daily living in poststroke individuals. Design Poststroke individuals who were able to walk without human assistance were recruited and asked to perform the following activities of daily living: washing dishes (activity code: 05041 in Ainsworth's compendium), walking at a slow pace of less than 2 mph (activity code: 17151), climbing stairs (activity code: 17133), and walking down stairs (activity code: 17070). The Metabolic Equivalent task was measured along these activities using a portable breath gas exchange analyzer. The measured values were then compared with Ainsworth's compendium. Results Thirty-five participants were included (mean [SD] age = 64.3 [14.3] yrs). The mean (SD) resting Metabolic rate was 3.08 (0.79) ml O2 kg(-1) min(-1). The Metabolic Equivalent task values were significantly higher than the compendium values: Metabolic Equivalent task washing dishes = 2.57 (0.96) versus 1.80 for compendium; Metabolic Equivalent task walking = 4.16 (0.93) versus 2.00 for compendium; Metabolic Equivalent task climbing stairs = 5.90 (1.43) versus 4.00 for compendium; Metabolic Equivalent task walking down stairs = 3.29 (0.48) versus 3.50 for compendium. Conclusions The Metabolic Equivalent tasks during activities were higher than Ainsworth's compendium. Stroke individuals are thus exposed to high oxygen requirements when performing activities of daily living, which could have a strong impact on their ability to perform these activities in real life.

Even a low-dose of moderate-to-vigorous physical activity reduces mortality by 22% in adults aged ≥60 years: a systematic review and meta-analysis
British Journal of Sports Medicine, 2015Co-Authors: David Hupin, Frédéric Roche, Vincent Grémeaux, Jean-claude Chatard, Mathieu Oriol, Jean-michel Gaspoz, Jean-claude Barthélémy, Pascal EdouardAbstract:Background The health benefits of 150 min a week of moderate-to-vigorous-intensity physical activity (MVPA) in older adults, as currently recommended, are well established, but the suggested dose in older adults is often not reached. Objectives We aimed to determine whether a lower dose of MVPA was effective in reducing mortality, in participants older than 60 years. Methods The PubMed and Embase databases were searched from inception to February 2015. Only prospective cohorts were included. Risk ratios of death were established into four doses based on weekly Metabolic Equivalent of Task (MET)-minutes, defined as inactive (reference), low (1-499), medium (500-999) or high (>= 1000). Data were pooled and analysed through a random effects model using comprehensive meta-analysis software. Results Of the 835 reports screened, nine cohort studies remained, totalling 122 417 participants, with a mean follow-up of 9.8 +/- 2.7 years and 18 122 reported deaths (14.8%). A low dose of MVPA resulted in a 22% reduction in mortality risk (RR=0.78 (95% CI 0.71 to 0.87) p

Metabolic Equivalent one size does not fit all
Centre for Health Research; Faculty of Health; Institute of Health and Biomedical Innovation, 2005Co-Authors: Nuala M Byrne, Andrew P Hills, Gary R Hunter, Roland L Weinsier, Y SchutzAbstract:The Metabolic Equivalent (MET) is a widely used physiological concept that represents a simple procedure for expressing energy cost of physical activities as multiples of resting Metabolic rate (RMR). The value equating 1 MET (3.5 ml O2•kg–1•min–1 or 1 kcal•kg–1•h–1) was first derived from the resting O2 consumption (O2) of one person, a 70-kg, 40-yr-old man. Given the extensive use of MET levels to quantify physical activity level or work output, we investigated the adequacy of this scientific convention. Subjects consisted of 642 women and 127 men, 18–74 yr of age, 35–186 kg in weight, who were weight stable and healthy, albeit obese in some cases. RMR was measured by indirect calorimetry using a ventilated hood system, and the energy cost of walking on a treadmill at 5.6 km/h was measured in a subsample of 49 men and 49 women (26–45 kg/m2; 29–47 yr). Average O2 and energy cost corresponding with rest (2.6 ± 0.4 ml O2•kg–1•min–1 and 0.84 ± 0.16 kcal•kg–1•h–1, respectively) were significantly lower than the commonly accepted 1-MET values of 3.5 ml O2•kg–1•min–1 and 1 kcal•kg–1•h–1, respectively. Body composition (fat mass and fat-free mass) accounted for 62% of the variance in resting O2 compared with age, which accounted for only 14%. For a large heterogeneous sample, the 1-MET value of 3.5 ml O2•kg–1•min–1 overestimates the actual resting O2 value on average by 35%, and the 1-MET of 1 kcal/h overestimates resting energy expenditure by 20%. Using measured or predicted RMR (ml O2•kg–1•min–1 or kcal•kg–1•h–1) as a correction factor can appropriately adjust for individual differences when estimating the energy cost of moderate intensity walking (5.6 km/h).

Physical activity and the risk of abdominal aortic aneurysm: a systematic review and meta-analysis of prospective studies.
Scientific reports, 2020Co-Authors: Dagfinn Aune, Teresa Norat, Mark Hamer, Abhijit Sen, Elsa Kobeissi, Elio RiboliAbstract:The association between physical activity and risk of abdominal aortic aneurysm has been inconsistent with some studies reporting a reduced risk while others have found no association. We conducted a systematic review and meta-analysis of prospective studies to quantify the association. PubMed and Embase databases were searched up to 3 October 2020. Prospective studies were included if they reported adjusted relative risk (RR) estimates and 95% confidence intervals (CIs) of abdominal aortic aneurysm associated with physical activity. Summary RRs (95% CIs) were estimated using a random effects model. Nine prospective studies (2073 cases, 409,732 participants) were included. The summary RR for high vs. low physical activity was 0.70 (95% CI: 0.56-0.87, I2 = 58%) and per 20 Metabolic Equivalent task (MET)-hours/week increase of activity was 0.84 (95% CI: 0.74-0.95, I2 = 59%, n = 6). Although the test for nonlinearity was not significant (p = 0.09) the association appeared to be stronger when increasing the physical activity level from 0 to around 20-25 MET-hours/week than at higher levels. The current meta-analysis suggest that higher physical activity may reduce the risk of abdominal aortic aneurysm, however, further studies are needed to clarify the dose-response relationship between different subtypes and intensities of activity and abdominal aortic aneurysm risk.
