A recent study published in the journal Applied Physiology, Nutrition and Metabolism has some very exciting findings in the fight against memory loss and dementia. The World Health Organization (WHO) says that around 50 million people worldwide have dementia. Currently, there’s no treatment or cure for dementia or even a way to alter its progression. That makes preventative treatments even more exciting. Thankfully, numerous new treatments are being investigated, which are at various stages of clinical trials. So it’s not all doom and gloom.
Although there is no cure, there are several things that can be done to support and improve the lives of individuals who have dementia, including: early diagnosis in order to promote early and optimal management; optimizing physical health, cognition, activity and well-being; identifying and treating accompanying physical illness; detecting and treating challenging behavioral and psychological symptoms; providing information and long-term support to carers.
And movement and exercise play a role in brain health. Exercise affects the brain in many ways. To start with, exercise generally increases your heart rate, which in turn pumps more oxygen to the brain. Exercise aids the release of hormones, which provide an excellent environment for the growth of new brain cells. Exercise also promotes brain plasticity by stimulating the growth of new connections between cells in many important cortical areas of the brain. Research from UCLA even demonstrated that exercise increased growth factors in the brain, which makes it easier for the brain to grow new neuronal connections.
While researchers are still trying to determine the exact critical factors that make exercise so good for the brain, the focus seems to be narrowing in on increased blood flow to the brain, surges of growth hormones, and massive expansion of the brain’s network of blood vessels.
Canadian researchers at McMaster University examined the impact of exercise on the brain. Their new study suggests that the intensity at which we get more movement and exercise in our lives is critical. In their research, they found that seniors who exercised using "short bursts of activity" saw an improvement of up to 30 percent in their memory performance, while participants who worked out at a steady-state, moderate level saw no improvement.
Jennifer Heisz, the lead author of the study, quoted in Science Daily, says, "There is urgent need for interventions that reduce dementia risk in healthy older adults. This work will help to inform the public on exercise prescriptions for brain health, so they know exactly what types of exercises boost memory and keep dementia at bay."
According to Paragraph 5, what types of exercises could boost seniors’ memory?
选项
A、A short-time high-intensity workout.
B、A long-time steady-rate workout.
C、A mild regular daily exercise.
D、A lower-intensity cardio exercise.
答案
A
解析
根据题干关键信息Paragraph 5可以定位至文章第五段。该段第二句指出Their new study suggests that the intensity at which we get more movement and exercise in our lives is critical (最新的研究表明,我们在生活中增加运动和锻炼的强度是至关重要的),之后具体举例说明seniors who exercised using "short bursts of activity" saw an improvement of up to 30 percent in their memory performance (参加“短时爆发性运动”的老年人的记忆力提高了30%),while participants who worked out at a steady-state, moderate level saw no improvement (而那些以稳定、中等水平运动的老年人则没有任何改善),由此可知,提高老年人的记忆力最有效的运动应该是短时且高强度的运动,故选项A为正确答案。根据上述分析可知,选项B“长期且稳定的运动”与原文相反,应排除。选项C “温和有规律的日常锻炼”和选项D“低强度的有氧运动”均不原文不符,故均排除。
