It is well known that exercise can improve cardiovascular function and reduce the likelihood of developing heart disease, diabetes and stroke. However, new research has shown that exercise can improve "brain health". Animals that are exposed to periods of regular exercise show improvements in learning and memory (cognitive abilities) compared to those that are inactive. How exercise improves brain function is not clear. However, several molecules important for growth of new connections in the brain and for growing new blood vessels appear to be particularly sensitive to exercise. In our research we are investigating these and other mechanisms using animal models of exercise that closely approximate human exercise patterns so that findings from the animal models can be more easily translated to humans. An especially novel aspect of our research is that we are exposing animals to a series of challenging mental activities (similar to solving puzzles in humans) that we think will cause changes in the brain similar to those produced by physical exercise. If this is the case then the combination of physical activity and mental stimulation may provide an optimal method for maintaining cognitive abilities throughout life.

众所周知，运动可以改善心血管功能，减少患心脏病、糖尿病和中风的可能性。然而，新的研究表明，运动可以改善“大脑健康”。与不活动的动物相比，定期锻炼的动物在学习和记忆（认知能力）方面有所改善。 运动如何改善大脑功能尚不清楚。然而，几种对大脑中新连接的生长和新血管的生长很重要的分子似乎对运动特别敏感。在我们的研究中，我们正在使用与人类运动模式非常接近的动物运动模型来研究这些和其他机制，以便动物模型的发现可以更容易地转化为人类。我们研究的一个特别新颖的方面是，我们将动物暴露于一系列具有挑战性的心理活动（类似于解决人类的谜题），我们认为这些活动会导致大脑发生类似于体育锻炼产生的变化。如果是这样的话，那么身体活动和精神刺激的结合可能会提供一种最佳的方法来维持整个生命的认知能力。
