Exercise

Brain-derived neurotrophic factor (BDNF) which is a protein, plays an important role in neuronalsurvival and growth which is essential for learning and memory (Bathina S, Das UN, 2015). Research suggests that physical exercise can affect BDNF levels both in the blood and thebrain, but how effective is exercise when compared...

  Exercise, in general, is beneficial for the brain, but is one type of exercise more beneficial formemory? That’s what the following research investigated.Sixty-four sedentary older adults either did high-intensity interval training, moderate continuoustraining or stretching as a control (Kovacevic A, et.al., 2019).The researchers found that high-intensity interval training resulted...

We know that sedentary behaviour is associated with impaired cognition and exercise can improve cognition. This research is interesting because it added a component to the exercise (Wheeler MJ, et.al., 2019). The participants were sedentary overweight/obese older adults with normal cognitive function. Cognitive testing were done and brain-derived neurotrophic growth...

Excess reactive oxygen species and oxidative damage have been associated with the pathogenesis of osteoarthritis.  Joint fluid from patients with osteoarthritis is characterized by significantly decreased extracellular superoxide dismutase (SOD) levels, a significantly decreased glutathione level, and ascorbate when compared to knee joints with intact cartilage (Regan EA, et.al., 2008)....

  Adding one thing can sometimes give you more than one benefit. This research was conducted to find out if dietary nitrate supplementation would improve exercise performance and cognitive function during a prolonged intermittent sprint test (Thompson C.,et.al., 2015). 16 male team-sport players received either 140 ml a day of beetroot...

A lot of people don’t exercise because they think they have to spend a lot of time doing it every week, and that does not appeal to them. Let’s see what research has found. Several years ago research was conducted on what was called high intensity short interval training. Since...

When you are sitting, the reduced muscular activity of the legs is decreasing the blood flow in the legs, deforming arterial segments. This is causing a decrease in shear stress of these arteries, causing reduced bio-availability of nitric oxide which again is increasing oxidative stress. The end result is impaired...

A Canadian study supports this where the researchers concluded that physical inactivity and a high waist circumference have a significant independent risk of premature mortality among women (Katzmarzyk PT, Craig CL, 2006). The participants of this study were all women, but other research has shown that this also works for...

As we get older we gradually experience a certain degree of brain atrophy. The rate of which the brain volume is changing is, however, not the same for everyone. The good news is that there is something you can do to slow down this process. An Austrian study of 201...

Elevated blood glucose causes damage to tissue and can increase low grade inflammation which increases the risk for chronic diseases.We have known for a long time that exercise helps to transfer the blood glucose into the cells, that way lowering the blood glucose.As it turns out it does not take...

We don’t need the same amount of salt all the time. Why is that? When it is hot and we perspire more, or when we exercise and perspire more, we lose more salt which needs to be replaced. On days like that, we need to eat more salt. One of...
