Jolanda Maas,a leader of a research at the Nivel Institute in Utrecht,has reported the result of the study in the magazine BiolMed Central Public Health.It says that people who live closest to green areas in the countryside walk and cycle less often for shorter time than other people.
"We found that there was either no relationship or only a small one between green space and physical activity," said Maas."People with more green space walk and cycle less often in their spare time."
People with 20% of green space walked around 250 minutes each week during their spare time compared to 180 minutes for those with 80% of green space.
"This may be because people in the countryside need to use their cars more to get to places such as shops,schools and the doctor's office." Maas said.
Living near green space also makes no difference in whether people met NHR to get 30 minutes of exercise daily,according to a survey of 5,000 people across the Netherlands.
"The study shows when you just look at how much green space people have,it is not true people are just more physically active," Maas said."This study shows you don't really need green space."
