    TEDx: Exercise and the Brain 

    Neuroscientist Wendy Susuki delivers a TEDx talk in Orlando, Florida. She presents the following question: can aerobic exercise improve your learning and cognition? Can it make you more creative? She discusses her attendance to Intensati classes, an exercise in which the participants repeat empowering mantras as they engage in movements. a class she developed at NYU titled “Can Exercise Change the Brain?” while teaching this class, she became a certified Intensati instructor. She conducted an experiment in which she conducted Intensati exercises in one class, and none in another. She found that the students who engaged in the exercise were extremely energized by the Intensati and that this energy carried over into the class lecture. She also found that students’ ability to retain information and succeed at memory tests were profoundly better in her exercise classes.

    In listening to Wendy Suzuki speak, I discovered that the hippocampus, which can be greatly effected by exercise, is important not only for memory, but also for creativity. Suzuki also made it clear that brains grow when exposed to enriched environments, such as exposure to exercise. This information is consistent with Better Than Yesterday’s video on exercise and the brain.

    Wendy Suzuki’s TEDx talk is relevant to my research as it specifically addresses practical effects of exercise on the brain. She conducted an experiment and presented practical information about how exercise effected her students’ memory and creativity.

    How Exercise Effects Your Brain 

    Better Than Yesterday’s video “How Exercise Effects Your Brain: Exercise and The Brain (animated)” discusses how the human brain experiences exercise versus sedentary behavior. Better Than Yesterday begins the video by dismissing myths about exercise. It is argued that exercise doesn’t necessarily “burn off” stress, but it instead enables the brain to perform at its best. The main point of exercise is to condition and build the brain. The brain’s main purpose, as brains are found in moving beings, is to perform complex motor movements. It is argued in the video that inactivity actually shrinks the brain and kills brain cells. Because of exercise’s profound effect on the brain, exercise positively effects depression, mood, and mental aging. In the video, exercise is compared to Prozac and Ritalin, without side effects.

    I learned of a metaphor that was very interesting to me. Better Than Yesterday states that koalas used to have larger brains, but then adapted to live off a simpler diet, and thus needed less movement to survive. As a result of this, koalas evolved to have smaller brains. Brains can grow or shrink, much like any other muscle in the body. In order to aid in brain growth, it is recommended to bring heart rate levels up to 80% for 30 minutes per day.

    Exercise and the Brain 

    Wellcasts’ video “Exercise and the Brain” shows an animated “gym rat” exercising and experiencing healthy mental clarity. Conversely, the other character in the video is an animated woman who is more sedentary and experiencing the symptoms of depression. Wellcast introduces their video with facts about exercise and the benefits of it as relates to depression. Wellcast then introduces a self care plan for the viewer. They instruct the viewer to take 3 steps: exercise for 30 minutes, journal about it, then do it for a week and write down how your mood has changed. Wellcast states that journaling in this process is essential as “the brain recognizes success as it sees it” (Wellcast).

    In viewing this video, I learned that the general consensus regarding recommended amount of exercise for the average person is 30 minutes per day. The video also stated that physically active people are half as likely to show signs of depression in comparison to sedentary people.

    Wellcast’s video is relevant to my studies because it presents the link between stress and exercise in a simple and accessible format. Wellcast uses humor to answer my question: what is the effect of exercise on stress?

    The Truth About Exercise – Prof. James Timmons lecture at Loughborough University 

    Professor James Timmons discusses the reasons behind why we as humans decide to participate in physical exercise and the actual benefits behind it. Personal reasons include the social aspect, vanity, strength, positive mood, etc. Medical reasons include the prevention of chronic ailments such as high blood pressure, heart disease, and cancer, and mental health issues such as depression and anxiety.

    Timmons argues that an improved healthy lifestyle that includes physical exercise is more effective than medication for reducing the risk of developing diabetes and several other illnesses. Exercise needs to be individually tailored to the individual, as different bodies have different physical needs. Although exercise has incredible benefits, Timmons makes the argument that it can not be prescribed as a treatment for disease. This documentary directly addresses my guiding question: “How does exercise combat the effects of stress on the body?” Why Zebras Don’t Get Ulcers and HEAL have concluded that stress leads to chronic illness and disease. Professor Timmons’ lecture argues that exercise prevents these illnesses and diseases, however should not be used to treat such ailments.
