Canadian scientists have found that the
more emotional or mental challenges a person faces in a day, the less
determined they become to work out physically.
However, the findings should not stop us
from keeping fit. Experts believe that willpower (意志力)is like a muscle , and needs to be exercised to
help one avoid the temptation (诱惑)spending a night on the couch instead.
Kathleen Martin 一 Ginis, a professor of
kinesiology 一 the
science of movement 一 who led the study, says everyone has a limited amount of willpower,
and that it will be reduced by stress. Miss Martin 一 Ginis, of Canada' s McMaster
University, explains, "Cognitive (认知的)tasks, as well as tasks such as regulating (调整)one' s emotions, can reduce
one' s capacity to force oneself to exercise."
Her team of scientists performed a so —
called " Stroop" test on volunteers to reach their conclusions. The
experiment involved showing participants words associated with colors but printed
in different colors - for example , the word " blue " written in red ink . ' Participants
were divided into two groups. One group was asked to name the color of the ink , instead to say the printed
word , while the
other wasn't Martin ― Ginis says , " After we used this cognitive task to use up their self 一 regulatory capacity, the
participants didn't exercise as hard as those who had not performed the task. ,, The more people concentrated
on the cognitive task , the more likely they were to skip exercise sessions (活动时间)over the next eight week.
You only have so much willpower .
However, there are ways to strengthen
willpower. The study found the listening to music before going to the gym can
help, as well as making a commitment to work out with friends. It also
concluded that willpower can be stretched by constantly cake , or forcing oneself to study an
extra hour each night.
Martin - Ginis adds, "There are
strategies people can use to help revitalize (使恢复活动) themselves after they’ve used up their self 一 regulation. Willpower is like
a muscle : it needs
to be used to stay strong.
