“…In our cohort, only ≈18% of participants met this guideline and had a 21% reduction of risk. Similarly, ≈80% of the adult population of East Asian countries, such as Taiwan, China, or Japan, did not meet this recommendation 3. The far more serious problem is that currently over half of our cohort did not participate in any level of MVPA and were in a physically inactive state.…”

“…However, more than half the people in the United States and the United Kingdom and even up to 80% of all adults in Asian countries failed to comply with the guideline,7, 8, 9 implying it is not a practical or easily achievable goal for Western societies’ people. Recent studies showed a minimum of 90 min/week of moderate‐intensity exercise or 30 to 59 min/week of vigorous‐intensity exercise are markedly beneficial for all‐cause and cardiovascular mortality 3, 10. We hypothesized that PAs, even below the current recommended level, are effective for preventing a first‐ever stroke.…”

BackgroundThe current guideline recommends moderate‐ to vigorous‐intensity physical activity (PA) at least 40 min/day for 3 to 4 days/week. Although recent evidence has demonstrated that low‐dose PA could reduce cardiovascular mortality, the relationship between low‐dose PA and the risk of stroke remains uncertain.Methods and ResultsUsing data from a nation‐wide sample cohort in Korea, we examined 336 326 individuals who received a general health examination between 2009 and 2010. Level of PA was assessed using a questionnaire for weekly PA frequencies regarding 3 intensity categories: light, moderate, and vigorous. Moderate‐ to vigorous‐intensity PA (MVPA) was classified into 4 frequency categories: none, 1 to 2, 3 to 4, or ≥5 times/week. Cox proportional hazard models were constructed to estimate the risk of stroke. During the average follow‐up of 3.6 years, 2213 stroke cases occurred. MVPA was none in 50%, 1 to 2 times/week in 20%, 3 to 4 times/week in 13%, and ≥5 times/week in 18% of the cohort. Individuals with MVPA 1 to 2 times/week had a 16% reduced risk of stroke (adjusted hazard ratio, 0.84; 95% confidence interval, 0.73–0.96) compared with those with no MVPA. The population attributable fraction of no MVPA was 12%, which was the second most important risk factor for a stroke after hypertension.ConclusionsEven 1 to 2 times a week of MVPA might be beneficial to prevent a first‐ever stroke in the general population, although a quantitative validation of the questionnaire is needed. From a public health perspective, we need to encourage inactive people to start exercising with more‐achievable goals.

“…The MT average of 260.4 active minutes per week is 73% more than the recommended Physical Activity Guidelines for Americans 2. A 2011 study by Wen and colleagues,39 which found that achieving 92 minutes per week of moderate‐intensity aerobic activity was associated with a 14% (95% CI, 9%–19%) reduction in all‐cause mortality and an additional 3 years in life expectancy compared to controls who exercised for <1 hour per week. Additionally, for each additional 15 minutes spent above the 92 minute per week threshold, there was a further 4% (95% CI, 2.5–7.0) reduction in all‐cause mortality 39…”

BackgroundSedentary work is hazardous. Over 80% of all US jobs are predominantly sedentary, placing full‐time office workers at increased risk for cardiovascular and metabolic morbidity and mortality. Thus, there is a critical need for effective workplace physical activity interventions. MapTrek is a mobile health platform that gamifies Fitbit use for the purpose of promoting physical activity. The purpose of this study was to test the efficacy of MapTrek for increasing daily steps and moderate‐intensity steps over 10 weeks in a sample of sedentary office workers.Methods and ResultsParticipants included 146 full‐time sedentary office workers aged 21 to 65 who reported sitting at least 75% of their workday. Each participant received a Fitbit Zip to wear daily throughout the intervention. Participants were randomized to either a: (1) Fitbit‐only group or 2) Fitbit + MapTrek group. Physical activity outcomes and intervention compliance were measured with the Fitbit activity monitor. The Fitbit + MapTrek group significantly increased daily steps (+2092 steps per day) and active minutes (+11.2 min/day) compared to the Fitbit‐only arm, but, on average, participants’ steps declined during the study period.ConclusionsMapTrek is an effective approach for increasing physical activity at a clinically meaningful level in sedentary office workers, but as with accelerometer use alone, the effect decreases over time.Clinical Trial Registration URL: https://www.clinicaltrials.gov.

“…[47][48][49][50] In a similar comparative meta-analysis of 277 patients with CHD, Elliot and colleagues demonstrated that HIIT was associated with a significantly higher VO2, which is independently associated with reduced CVD mortality. 51 Larger national cohort studies across the globe support these findings in disease- 53,54 In case control and cohort studies of CHD patients, high intensity ET has been shown to elicit higher aerobic capacity, improved endothelial function, and enhanced HRQoL. 55 In cohort studies of individuals with metabolic syndrome, HIIT improved fat oxidation and fasting glucose levels, as well as VO2.…”
