A new research, conducted by the team of neurologists from the Netherlands, finds that intensive physical activity may lead to amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease.
To assess the connection between physical activity and ALS, a team of scientists investigated the lifestyles of more than 1,500 adults with the diagnosis of ALS in Ireland, Italy, and The Netherlands. These data contained information on their lifetime physical activity levels, their gender, educational attainment, employment history, and smoking and alcohol intake.
According to the received data, the average heightened risk for physical activity in leisure time was 7%, and 6% for occupational physical activity.
The team says the overall risk can be as high as a 26% increase in risk when comparing a person who is more active than average with one who is significantly less active than average.
A new research from the University of Missouri in Columbia finds that physical activity may alter men’s food preferences. However, the food preferences of women are likely to remain the same, study says.
For the study, a team of researchers studied male and female rats splitting them into two mixed-sex groups. The first group had access to a running wheel (the exercise group), the second group did not (sedentary group). Both groups had access to various types of diets.
In the end of the experiment, the scientists noted that exercising female rats continued to choose high-fat diet over other two diets, and exercising male rats reduces their intake of the high-fat diet and increased their intake of the high-sucrose and high-cornstarch diets.
The team concludes: “The significant sex differences in response to physical activity observed through both behavioral and physiological measures suggest potential motivational or metabolic difference between males and females.”
A new study from the University of Wisconsin-Medison finds that moderate physical activity may lead to healthier brain functions in people at higher risk of developing Alzheimer’s disease.
In the course of the study, the scientists discovered that those participants who spent more than an hour per day taking part in moderate physical exercise demonstrated higher and healthier levels of glucose metabolism, the process giving brain cells the right amount of fuel, compared to those participants who did not exercise.
Ryan Dougherty, one of the researchers, says: “This study has implications for guiding exercise ‘prescriptions’ that could help protect the brain from Alzheimer’s disease. While many people become discouraged about Alzheimer’s disease because they feel there’s little they can do to protect against it, these results suggest that engaging in moderate physical activity may slow down the progression of the disease.”
According to a new study from the Mayo Clinic in Minnesota, high-intensity interval training (HIIT), when short intervals of activity are changed to rest periods, is the best way to keep your cells young.
The study included 72 volunteers, 36 men and 36 women, and divided them into groups according to age: a young group included those between 18 and 30, and an old group consisted of people aged between 65 and 80 years.
After a period of various regimes of training, the researcher concluded that at the molecular level, HIIT produced the biggest benefits, with the younger participants on HIIT showing a 49% increase in mitochondrial capacity, and the older participants on HIIT reaching a 69% on average.
Moreover, the scientists say the regeneration of muscle protein seen in this study could also be replicated in the heart and brain, two other areas of the body where cells wear out more easily as people age.
Physical activities are necessary not only for those who want to lose weight but also for all people in the world. Scientists prove that moderate activity, besides keeping us in good physical shape, boosts our mental health and prevents many chronic diseases.
So these are the 10 best activities with approximate calories burned per hour calculated for 91 kg (200 kg) person for each activity on the list. Naturally, exact figures depend on the body type, age, and other personal factors. These amazing activities include:
