Exercise appears to lower atrial fibrillation and stroke risk

The link between exercise and atrial fibrillation (afib) and stroke prevention is now a little clearer, thanks to a Harvard study. It offers strong evidence that 150 minutes per week of moderate-to-vigorous physical activity is associated with a reduced risk for atrial fibrillation and stroke. Researchers aren’t surprised, since exercise helps the chambers of the heart contract and relax, while being sedentary increases afib and stroke risk. Other ways to ward off afib and stroke include treating sleep apnea, quitting smoking, and drinking only in moderation.

Why am I so tired after exercising?

Overtraining is the point at which people train so hard and for so many hours that recovery does not occur after regular periods of rest. This can lead to post-exercise fatigue. Many health issues also can cause the problem, such as anxiety, depression, an unhealthy diet, or poor sleep. Taking time off and spreading out exercise days often can improve fatigue. If not, see a doctor.

Tai chi offers similar benefits as conventional exercise

Tai chi helps improve balance and coordination, especially among older adults. Now, a study has shown that the ancient mind-body practice also can offer health benefits similar to conventional exercise like aerobics and strength training.

How low can you go?

Short-duration high-intensity interval training (HIIT) has been shown to have similar—and possibly better—health benefits than longer, lower-intensity exercise. HIIT workouts consist of quick spurts of draining physical effort, followed by rest, repeated multiple times, and usually last from 15 to 30 minutes. Research has found it’s possible to shrink HIIT workouts to five to 10 minutes—known as low-volume HIIT—and still receive benefits. Consistent intensity and attention to form and execution are needed to be effective.

The best types of exercise when you have hip or knee pain

Non-weight-bearing exercise takes the burden off the hips and knees and makes it easier for people with joint pain to exercise. Exercise machines that are gentle on the joints include an elliptical trainer, a stationary bike, and a rowing machine. Low-impact exercises can also provide a good cardio workout and muscle strengthening without stressing the joints. Examples include pool exercises, tai chi, and short walks at a brisk pace.

Exercise challenge: Part 2

Performing exercises such as side planks, bridges, and squats can improve muscle strength. Ideally, people should do weight-bearing exercises at least twice a week. Having stronger muscles improves balance, protects bone health, and can help keep people independent as they age. It can also reduce pain from conditions such as osteoarthritis.

Get SMART about your fitness goals

You are more likely to achieve and maintain your fitness goal if it revolves around a specific purpose or cause in one’s life. This helps you define the structure and direction to adopt the right exercise program to help fulfill it. The SMART approach—Specific, Measurable, Achievable, Relevant, and Timely—helps you define your fitness goal and create a realistic path to achieve it.

Does exercise really boost energy levels?

Exercise can create physical changes that help increase energy levels inside the body. In addition, it can induce better sleep at night, which helps people feel more energetic in the morning.

Is a "normal" blood pressure reading too high for women?

A study published Feb. 16, 2021, in Circulation found that women with blood pressure readings in a normal range may still be at higher risk for cardiovascular events. For example, heart attack risk in women rose at a systolic (the upper number) reading of 110 to 119 millimeters of mercury (mm Hg) and was the same at this level as men with a systolic pressure of 160 mm Hg. But experts say it’s too soon to change blood pressure recommendations for women until more research confirms the results.
