It is well known that vigorous exercise in unfit, sedentary individuals can trigger an adverse cardiac event, but this now appears to be true in fit individuals as well. Additionally, aerobic physical activity has been shown to decrease systolic blood pressure by 2 to 5 mm Hg and diastolic blood pressure by 1 to 4 mm Hg.Īlthough there are certainly benefits to exercise, recent research focusing on the high end of the exercise dose-response range suggests that chronic endurance training can cause transient myocardial changes. Abiding by these guidelines over 12 weeks has been shown to reduce LDL cholesterol levels by 0.08 to 0.16 mmol/L and non-HDL cholesterol levels by 0.16 mmol/L. Similarly, the American College of Cardiology recommends moderate- to vigorous-intensity physical activity for 40 minutes, 3 to 4 times per week. According to the World Health Organization, a minimum of 150 minutes of moderate intensity or 75 minutes of vigorous-intensity aerobic activity per week is recommended to achieve health benefits. Regular exercise is effective in the prevention and treatment of conditions such as hyper-tension, coronary artery disease (CAD), heart failure, obesity, and diabetes. The law of diminishing returns appears to apply as exercise extent increase, and it is likely that an upper limit exists where additional physical activity provides no further mortality benefit. Some evidence suggests that years of endurance training can lead to long-term adverse consequences, including myocardial fibrosis, atrial fibrillation, an exercise-induced acquired form of arrhythmogenic right ventricular cardiomyopathy, ventricular arrhythmias, and coronary atherosclerosis. With the increase in individuals participating in ultra-endurance events, recent research has focused on the high end of the exercise dose-response range and found that chronic endurance training can cause transient myocardial changes, possibly due to repetitive transient pressure and volume overload on the thin-walled left atrium and right ventricle. Studies have investigated ideal amounts or “doses” of exercise to decrease risk factors associated with disease, as well as the minimum amount of exercise required to reduce mortality. The proposal would also add an additional 20-cent fee on rides that start and end in the MBTA’s service area.ABSTRACT: Regular exercise is effective in the prevention and treatment of conditions such as hypertension, coronary artery disease, and diabetes. The Senate proposal calls for increasing the current flat 20 cent fee per trip to 40 cents for a shared ride, $1.20 for a non-shared ride and $2.20 for a luxury ride. The average speed in 2018 was 18.6 miles per hour and in 2017 it was 17.7 miles per hour.Įfforts to raise the fees assessed on Uber and Lyft rides have been unsuccessful the last few years, but the Senate budget proposal gives it another try this year. Using speed as a barometer for congestion, 2019 had the highest congestion of the four years rideshare data have been gathered. He lives in Dorchester.The faster speeds in 2020 undoubtedly reflect the decline in traffic congestion during the pandemic.
