Can Exercise Be Harmful For You?

We all know that exercise can surely boost the quality of sleep. But what about intense exercise? Is it good or bad for your sleep? Well, a new research found that intense workouts may gradually decline the quality of sleep. The same research says that people who intensely workout need to consume more carbs to minimize the effects of exercise on sleep. 

 The study was conducted on 13 people who were allowed to embrace intense workouts during the tenure. Apart from the quality of sleep, researchers also kept an eye on the moods of the participants and their average performance.

At the end, it was concluded that over exercising can progressively decline the quality of sleep. In the research, the participants failed to enjoy deep sleep during the days when they over trained. As days passed by, even the performance declined due to lack of quality of sleep. Well, how much is too much when it comes to over training? Well, this depends upon a lot of factors as we are all different in various ways.

But yes, your gym trainer can determine how much your body can take as he must be observing your strength and endurance levels on a daily basis.

How jogging helps you stay sharp for life and keep your brain healthy

Exercise can enhance the development of new brain cells that play an important role in learning and memory of adults, new research has found.

The process of developing new brain cells in the adult brain is called adult neurogenesis, the scientists explained.

The researchers found that mice that spent time running on wheels not only developed twice the normal number of new neurons, but also showed an increased ability to distinguish new objects from familiar objects.

“Our research indicates that exercise-induced increase in neurogenesis improves pattern separation by supporting unique and detailed long-term representations of similar but nevertheless different memory items,” explained lead investigator Josef Bischofberger,  professor at University of Basel in Switzerland.

“Pattern separation is involved in many memory tasks of everyday life. For example, when learning the game of chess, it is critically important to remember the different shapes of pieces like the pawn and bishop,” Bischofberger explained.

For the study, the researchers tested two groups of mice that were housed either without (sedentary) or with running wheels (voluntarily running) using a novel object recognition  task to assess learning and long-term memory.

The researchers found that whereas distinct objects were remembered and recognized by both cohorts of mice, only the running mice could faithfully distinguish similar looking objects.

Investigators determined therefore that the running mice had developed better pattern separation capabilities than sedentary mice.

To investigate further, the researchers looked for changes in the brains of the mice. By using markers that could identify newly-formed brain cells, they found that running mice developed about twice as many new cells.

The study was published in the journal of Brain Plasticity. (IANS)
