Brain Observation

Enhancing cardiac output allows you to maintain lower heart rates during physical activity. For example, at the start of a program you may have a heart rate of 150 beats per minute while running at a 6 mph pace. After three or more months of training increased cardiac output enables you to sustain the same running intensity at a lower heart rate such as 125 beats per

In the article titled, “Secrets of the Brain” published in the February 2014 issue of National Geographic, we learn that there have been many advances in understanding the inner workings of our brains. One of the leading scentists, Van Weeden, is working hard to understand the connections that occur within our heads.

This is what causes some students to get minutes easier than others. If their heart rate is at or higher than the standard resting heart rate used for the class, they are able to acquire minutes easier in the area known to teachers and students as the “zone”.

You can choose to get the model with a heart rate monitor or one without this feature. If you get the heart rate monitor version, you’ll also get a chest band that has to be worn during activity to accurately measure your heart rate.

Heart rate zone training is a great way to train. This training method involves tracking heart rate and determining heart rate zones in order to maximize workout efforts. All that is required is some drive, a heart rate training app, a HR (heart rate) monitor and an exercise plan. The key is knowing your numbers and knowing how to train with a heart rate monitor. Here’s why heart rate zone training is so important.

Understanding the brain’s physical operation is essential to frame the relationship between brain and mind. The brain functions as a result of many complex processes; however, Jeeves and Brown narrow the brain’s activity into eight critical principles. These principles provide a background necessary to deduce insightful information from neuroscience’s current research of the correlation between our mental lives and brain systems.

Due to the fact that I love psychology I was drawn to the research about advances in neuroscience. The article is titled “Secrets of the Brain,” by Carl Zimmer and was printed in the February, 2014 National Geographic. Here is a link to the article-

The experiment’s design included two sections. One section was the survey responses, and the other was the ECG measurements. In this experiment, the subjects were 18 college students. In the experiment, the independent variable was the hours of exercise and life style habits, and the dependent variable was the changes in heartrate before and after exercise. In the survey section, the survey questions asked about the subjects’ background information. These background related questions includes: Gender, Age, and medical conditions. Additionally, the questions asked about their life styles and exercise habits. Example of these questions are: The frequency of their exercise, the intensity of their exercise, and the specific type of their exercise.

Figure 1 results showed that the ice-vest tests beginning and end HR difference was 69.33 bpm

Heart rate variability (HRV) is quickly becoming a “buzz word” in fitness, but in reality this is a very old technology. Dating back to at least 1948 (15) HRV has been a commonly used method in research and is an accepted diagnostic tool in several diseases/conditions, such as post-traumatic stress disorder and type 2 diabetes (9, 23).

In order for a heart to be functioning properly, several physiological criteria must be met. The blood vessels to the heart need to be functioning normally. The electrical conduction system has to be working in a coordinated fashion for the blood to flow efficiently through the heart chambers. Also, all of the heart valves need to be working optimally so that blood can flow in the proper direction and in adequate amounts. Finally, the arterial and venous systems need to be able to constrict and dilate so that proper blood pressure is maintained and also so all of the cells of the body get an adequate blood flow (Anonymous C 2015). The exercise group for this experiment is the group that’s more likely to have met all these requirements at a more satisfactory level than the non-exercise group, and therefore, are at less risk of cardiovascular diseases. Aerobic exercise breaks up stored fatty acids to provide more fuel to the heart (Levitt 2012). Without exercise, excess energy obtained from food for example, will be stored as fat which can lead to obesity. Nearly 70% of American adults are either overweight or obese. Being obese increases risk for heart disease, stroke, high blood pressure, diabetes and more (American Heart Association B 2014).

At 15 minutes when the exercise stoped their heartbeats rapidly shot down until a bit above their original heartbeat.

The brain is possibly the most fascinating thing in this entire world. It controls and creates our realities. The brain functions through three different mind levels- conscious, subconscious, and unconscious.The idea of three levels of mind was introduced by an Austrian psychologist, Sigmund Freud. He used an Iceberg as an analogy to describe each level in the brain.( Appendix #) The tip of the Iceberg is the conscious level and it represents about 10% of the brain’s capacity. Humans spend more time living their day to day lives using the conscious mind. Next level is the subconscious and it is responsible for 50-60% of the brain’s capacity and is used to communicate between the conscious and unconscious level. Lastly, the

For year’s scientist, philosophers, and specialists have delved into studies on the inner workings of the brain. With each new discovery, new questions arise looking beyond the physical brain and into the areas of judgment and emotions. Questions regarding the mind-body connection can be traced back to Descartes, a philosopher, who looked at how the material body was affected by the mind, or soul. Descartes studies were only the beginning of the discussion which has now been stretched to include questions of free will, emotions and judgment.
