Blood-flow Restriction Training Delay the Progression of Chronic Kidney Disease

Chronic kidney disease (CKD) is recognized as a public health problem, affecting more than 15% of the population. Although CKD can drastically impair health, it is rarely diagnosed early due to its silent revelation. Identifying and proposing treatments to attenuate…

Reduced Sitting Time Improves Blood Flow in Brain and Legs

During a regular day, the average person sits for eight to 10 hours. These high levels of sitting time seem linked to an increased risk for both cardiovascular and cerebrovascular diseases. First, researchers found that three hours of sitting results…

Attenuated Rapid-Onset Vasodilation to Forearm Muscle Contraction in Black Men

Kaur and colleagues reported that rapid onset vasodilation induced by a single contraction of the forearm muscles was significantly attenuated in non-Hispanic Black men, compared to white men, and this attenuation was evident even at low intensity muscle contractions. The…

Time-restricted Eating Reduces Body Weight in Runners without Impacting Performance

Intermittent fasting is becoming increasingly popular due to its simple advice: Don’t change what you eat; simply change when you eat. One popular method of intermittent fasting, 16:8 time-restricted eating (TRE), involves 16 hours fasting and eight hours eating each…

Detection of Blood Transfusion

Autologous blood transfusion is performance enhancing, and detection of abuse remains a major challenge in sports. To address this issue, investigators transfused a group of men with either blood or saline, and evaluated whether metabolites collected in urine before and…

BFFs: How Physical Exercise Impacts Brain Blood Flow, Memory after Paralysis

Thanks to advances in health care in the past several decades, more than 90% of people who have had a spinal cord injury survive beyond the first year. The focus now is managing the long-term impact of spinal cord injury…

Break Up Your Work Day with Healthy Stair Climbing Exercise Snacks

Sitting for long periods is known to have negative effects on metabolic and cardiovascular health. Building on recent work showing that brief bouts of vigorous exercise (exercise “snacks”) can improve fitness, investigators from the University of British Columbia in Canada…

New Year, New Weight Loss Program? Exercise More Important than Protein for Muscle Function in Older Women

November 5, 2020 sarah JonasAnnouncement

In the U.S., most older women are overweight or obese, which can harm functional health like rising from a chair. Weight loss diets that are higher in protein are popular as they often cause greater body fat loss while keeping…

Move More or Sit Less: How to Maintain a Healthy Brain

Worldwide, a person is diagnosed with dementia every three seconds. Regular physical activity and limited sedentary behavior (i.e., time spent sitting or lying down) are two important lifestyle strategies for maintaining good brain health. However, we do not know which…

Menopause May Affect Improvements in Exercise Fitness

All women go through menopause, usually between the ages of 46 and 54. Their periods stop, and they can no longer get pregnant. Postmenopausal women also have lower heart function. This study investigated whether menopause influences heart function and exercise…

Quantity and Context of Physical Activity: Important Factors in the Relationship with Pain

Many people are affected by painful conditions like low back pain, arthritis and cancer. Pain can be difficult to treat, with few safe and effective options. Some research suggests that being physically active can reduce the severity and impact of…
