It's well known that physical exercise is beneficial not just to physical health but also to mental health.Yet whereas most countries have     26     evidence-backed guidelines on the type and intensity of exercise     27    for various physical health benefits,such guidelines do not yet exist for exercise and mood. This is     28    due to a lack of necessary evidence.However,a new systematic review brings us usefully up-  to-date on the current findings in this area.

Before      29     into   some  of  the  key  take-aways,an   important     30     made  in  the  review  is  between  aerobic  exercise  and  anaerobic.The  former 31        such  things  as  walking,jogging  and  cycling  and  means  exercising in  such  a way that your body is able to use oxygen to burn  fat for energy.In contrast,anaerobic exercise—such  as  lifting  heavy  weights—is  of  such       32    intensity  that  your  body  does  not  have time to use oxygen to create energy and so instead it breaksdown glucose(葡萄糖)in your blood or muscles.

Beginning  first  with  the  influence  of  exercise  intensity  on  the  mood  benefits  of  aerobic  exercise,the researchers,led  by  John  Chan  at   Shenzhen  University,found 33          resultsfrom   19   relevant   studies.Some  favoured higher intensity,others low,while  seven  studies  found that intensity made no     34     _to mood benefits.

In relation to the intensity of anaerobic exercise,however,the results were far clearer—the optimum (最佳选择)for improving mood is      35     intensity,perhaps  because  low intensity is too dull while high intensity is too unpleasant
