Total amount of exercise important not frequency research shows
Monday, May 5, 2014
A new study by Queen’s University researchers has determined that adults who accumulated 150 minutes of exercise on a few days of the week were not any less healthy than adults who exercised more frequently throughout the week.
Ian Janssen and his graduate student Janine Clarke studied 2,324 adults from across Canada to determine whether the frequency of physical activity throughout the week is associated with risk factors for diabetes, heart disease and stroke.
“The findings indicate that it does not matter how adults choose to accumulate their 150 weekly minutes of physical activity,” says Dr. Janssen. “For instance, someone who did not perform any physical activity on Monday to Friday but was active for 150 minutes over the weekend would obtain the same health benefits from their activity as someone who accumulated 150 minutes of activity over the week by doing 20-25 minutes of activity on a daily basis.”
Physical activity was measured continuously throughout the week by having research participants wear accelerometers on their waists. Accelerometers are tiny electrical devices (about the size of a small package of matches) that record how much a person moves every minute.
Dr. Janssen divided the adults who met the physical activity guidelines (more than 150 minutes per week of aerobic activity) into those who were frequently active (active five to seven days of the week) and infrequently active (active one to four days of the week).
“The important message is that adults should aim to accumulate at least 150 minutes of weekly physical activity in whatever pattern that works for their schedule.”

The crucial role of the amount of water
Wednesday, April 30, 2014
Most people know they should drink plenty of water every day, but how many actually do?
You really if you pay close attention to your water intake maybe youd be surprised how little you actually consume.
What makes the appropriate amount of water so important amazingly?
Well for starters, its the most abundant element in the body. Ranked 2 only to oxygen as essential for life. Can survive your body for weeks without food, but without water you had died within a few days.
% Is made almost 80water of the body is composed of water, the brain is 85% water and lean muscle tissue is 70% water.
Research has shown that being a little dried up can reduce the strength and physical performance significantly. In fact, just a drop in water levels of 3-4% in the body leads to a 10-20% decrease in muscle contractions.
Water will not only increase your strength, but it also plays a big role in the prevention of injuries in the gym. Can be trained very intensely over a long period of time putting more pressure on the joints unwanted and connective tissue, and water helps to combat this tension by lubricating the joints and the formation of protective cushion around them.
