Introduction Many activities of daily living in modern society require sufficient time to react. These stimuli often involve choosing the best option between several possibilities. Thus in neuroscience, an experimental measure of a person’s cognitive ability is by subjecting them to a Choice Reaction Time (CRT) test. Central processing and planning of fine motor patterns occurs within the cerebellum to rapidly perform choice reaction tasks (Welford, A 1980). Previous studies have shown that the arousal level of an individual (often measured as a percentage of heart rate), directly affects their cognitive performance relating to the processing of several choices. Davranche et al. (2004) proved that moderate exercise (50% of VO2 peak) improves cognitive performance with regards to choice reaction time. However, a more recent study found that increasing a subject’s arousal only improved CRT in highly skilled fencing athletes, whilst having no effect on the sedentary population (Mouelhi Guizani, S. et al, 2006). Therefore, this experimental study is designed to determine the effects of varying heart rates upon CRT within a young, physically active male population. Purpose The aim of this experiment is to investigate the effect heart rate has on reaction time. The information that is obtained will be of interest to athletes in particular whose ability to react may be dependant on their arousal level. It has been shown that an ideal (optimum) heart rate can be achieved in order to minimise an individual’s choice reaction time. However, there is a lack of evidence supporting this notion to the physically active, young population and it is for this reason, that it is imperative that we forego this experiment.

area of focus and remembering (Asp 2). Not all exercise affects the brain in the same way. Studies have been done that link certain exercises to increase brain activity. An example of this is high intensity training is linked to great immediate mental performance (Asp 3). Slow aerobic exercise is linked to retaining information over time (Asp 4).

Introduction: In year 10, biology, we have been studying the heart: the functions of the heart, the parts of the heart (ventricle, atrium) and heart problems. Besides that we have been studying the heart rate of humans. We were asked to create an experiment to see what affects heart rate. We discovered that diet, stress, cholesterol level, excitement, mass, age, temperature and exercise affected the heart. Diet and exercise were the only 2 doable and so my partner and I chose exercise. We determined that as the intensity of an exercise increased so did the heart rate of the person performing it.
The data recorded supports the hypothesis, as during the trials the heart rate, breathing rate increases from resting body results as well as that the body temperature remained at an constant temperature. Many changes occurred in heart rate, breathing rate and body temperature. As seen in graph 1 the heart rate was very unstable throughout the trials. This is due to homeostasis. The heart rate rapidly increases in all the trials, but then slowly decreases after the 5-minute resting period. The heart rate increases while doing exercise, as the heart speeds up the oxygen to the muscles. As seen in graph 2 the breathing rate increase while doing exercise, but then later decreases to maintain a stable breathing rate. The breathing rate in this
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration

Physical exercise has been proven to help rebuild brain cells and activate proper and healthy cognitive functioning in adults. This relates to cognition in psychology because the studies show that there is a physical change in brain capacity, memory and cell growth from regular and efficient exercise. One of the more important aspects of the paper that I will focus on is the effect that exercise has on attention in children which helps regulate cognitive functioning and promotes further development and learning. These articles go over neuroscience that backs up the fact that exercise is crucial for brain development of children and teens, and the importance of renewing and growing healthy brain cells that also effect cognitive functioning.
From breaking down these variables in response to exercise, relationships are proportional to increasing exercise intensity. At rest, heart rate is around 60-80 beats/min. Sympathetic stimulation effects fuel an anticipatory response that cause the heart rate to rise until a maximum heart rate. During max exercise, stroke volume increases in preload and contractility, but decreases in
This information could be useful when counseling athletes or individuals initiating strenuous exercise (Lokuta 2017).
Past studies in both animals and humans have proposed that length of exercise is associated with better cognitive function (Colcombe & Kramer, 2003; Holmes, Galea, Mistlberger, & Kempermann, 2004). However, other studies have proposed that only small doses of exercise are needed to see significant health benefits (Beddhu, Wei, Marcus, Chonchol, & Greene, 2015; Hupin et al., 2015). Past studies have also found that shorter duration high-intensity regimens are also beneficial in regard to cardiovascular and metabolic function, musculoskeletal benefits and cognitive performance. (Gibala et al., 2006; Gillen, 2012; May et al.,
2008). In other words, there is an interaction between caffeine intake and muscle mass that determines pulse rate and in this experiment, muscle mass was a variable that was not accounted for. Furthermore, the resting pulse rate response to caffeine consumption prior to exercise is considered one of the most variable parameters of those in the study. Because this experiment measured resting pulse rate less than one hour before exercise, it is not completely reliable as a study by Bailey (1989) similarly suggested the implications of pulse rate variability to be a factor of the fluctuating results across subjects despite
The study will critically analyze the Functional Movement Screen developed by Cook, et al., (2006). According to Schneiders, et al., (2010), “the Functional Movement Screen was developed as a comprehensive pre-participation and pre-season screen tool that challenges an individual’s ability to perform basic movement patterns ” (p.76). Cook, et al., (2006) developed the FMS when there was not a functional evaluation standard to make rehabilitation protocols that take into account how a patient functionally moves (p.62). The FMS is an evaluation tool that is comprised of 7 fundamental movements to assess an individual mobility and stability (Cook, et al., 2006, p.63). Observation has indicated that athletes cannot perform
By running competitively one can increase the capacity of their brain; running boosts one’s ability to learn and has been known to help people to be able to focus better. Competitive running has extremely good benefits on the cognitive abilities of people who take part in the sport. Scientists studying the effects or running on cognitive abilities have found that competitive runners outperformed recreational runners in the abilities requiring motor inhibition, competitive runners were also found to be better at multitasking, and successfully ignoring information that was not necessarily relevant. Competitive running is shown to have bigger impacts on the brain than recreational running; as this may be true, running in general has still been
The pre-treatment resting pulse rate was expected to be same as healthy people who were not trained athletes should have similar pulse rate ranging from 60 beats per minute to 100 beats per minute. In the caffeinated treatment group, the resting pulse rate increases after acute consumption of caffeine which corresponded with the prediction of caffeine’s effect in increasing heart rate, but the increase is not substantial, thus it may be due to errors. However, no significance in difference in post-treatment resting pulse rate and post-exercise pulse rate indicated that caffeine did not contribute to the increase in pulse rate during exercise. Thus, the result rejected the hypothesis of caffeine’s effect of increasing pulse rate/aerobic capacity during
