Energy Pathways
Understanding the energy pathways is critical for personal trainers. In particular, it is essential to comprehend phosphagen system, anaerobic, and aerobic system which provide the much-needed energy for normal functioning of the body. During training sessions, extra energy is needed to sustain the increased metabolism. Therefore, mastering each of the three systems can assist in programming the training session. Phosphagen system, which uses Creatine Phosphate (CP), is regarded as an immediate source of energy. However, muscle cells can only store a small amount of ATP and CP that is used in the process. The pathway can sustain short-term, but high-intensity activities such as throwing a ball and sprinting since energy released can only last for around 10 seconds. In contrast, anaerobic pathway supplies energy at a moderate rate since it requires a total of 12 chemical reactions to produce energy from carbohydrates. Therefore, anaerobic pathway produces enough power to sustain activities requiring a tremendous burst of energy over an extended period; for example, body weight squats and pushups. As the name suggest, oxygen is needed in aerobic pathway to burn carbohydrates and fats. Compared to anaerobic and phosphagen, aerobic has the slowest rate of energy production. Hence, anaerobic system provides energy for longer-duration but lower-intensity activities such marathon or long distance swimming.
I would focus on aerobic pathway as the focal point for training if my training is meant for a marathon competition. In particular, I would focus on activities that offer aerobic endurance. For example, jogging for at least six miles a day allows the body of an athlete to get used to an extended period of activity. The body will react by building the capacity to provide the oxygen and energy required during the marathon. However, including sprinting at the end of jogging is a necessary deviation from aerobic to the anaerobic pathway. The idea is to allow the marathoner to take advantage of the anaerobic pathway to run faster in the last two hundred meters in the race. Such a spirited finish can be a defining moment especially when several competitors are close enough to overtake each other.
In my view, the secret to succeeding in sport lies in understanding the physiological functioning of the body. The three pathways summarize everything that trainers, sportspersons, or any other person need to understand before starting exercising. As a trainer, the lessons on energy pathways have enlightened me in several ways. Firstly, I am now in a better position to make an informed decision on the most suitable exercises for each sport depending on the duration and energy needs. Secondly, I can confidently manage my client in a far much professional manner by choosing what to do, when to do it, and when to rest. This lesson is crucial in ensuring optimal functioning, guaranteed success, and a safe working environment by avoiding unfortunate incidence such as exhaustion before completing a competition or training session. Lastly, the understanding of anaerobic and aerobic pathways places me in a better position to train and manager sportsmen and women. In my view, a trainer should always thrive to ensure his or her client wins. Therefore, an understanding of the energy pathway is critical during training. I intend to use this knowledge to train my clients how to go about different stages of racing to avoid the buildup of lactic acid and the exhaustion that comes with it.
Chin-ups versus Pull-ups
After doing chin-ups and pull-ups, I realize that the two exercises differed significantly concerning the muscles involved. During chip-ups, I felt that biceps made the most movement. As I pulled myself upwards, the action of the biceps was noticeably visible. Therefore, based on the pressure that my body weight exerted, I am convinced that the bicep is the prime mover since it is the primary muscle involved in the movement. In other words, its contraction played the central role in the movement. I also felt that the pectoralis provided the much-needed stabilization to facilitate the change. Another noticeable shift occurred in the brachialis since its contraction eased the movement of the arm; hence, the muscles played a synergistic role. Using one arm to pull myself up, I had a chance to feel the hardening of the brachialis as well as the biceps. In contrast, push-ups involved a different set of muscles. For instance, I felt that my entire body weighted rested on the brachioradialis. However, the movements of the brachialis remained the same as in chin-ups.
My intention to be a personal trainer is informed by my desire to provide evidence-based service to my clients. Therefore, the experience I had while doing pushups and chin-ups was insightful in learning about the movement of muscles. In future, I plan to continue exercising while paying close attention to the movement of muscles. In doing so, I will be better informed about the best way to engage all the necessary muscles. My focus will be to differentiate the various tissues. For example, I interested in understanding the role of different sets of muscles including prime movers, synergists, stabilizers, and antagonists. My goal is to become informed regarding the best way to engage all the muscles with the aim of achieving a steady muscle buildup and endurance. More specifically, gaining the knowledge will assist me in avoiding exercises that bring little or no outcome.
Aerobic Training in Burning Fat
While conducting personal research, I came across various websites describing how aerobic is an excellent remedy for burning fat. Most of these health-related websites focused on the belly fat by showing how aerobic exercises lead to a significant improvement. For instance, Live Science website posted an article on how aerobic training led to a loss of 2.5 square inches of belly fat after eight months. According to the report, resistance training can improve strength as well as increase lean body mass.
As discussed earlier, the anaerobic pathway is the only system that leads to the conversion of fats into energy. This is critical information in understanding how aerobic training helps in burning fat. The thought is to engage the body in an extended training session. In doing so, the body ends up converting the stored fats. Therefore, the claim is justifiable since empirical evidence supports it. The best approach is to examine how endurance training plays a crucial role in creating the much-need capacity for the metabolism of body fats. In particular, endurance training promote the growth of mitochondria while at the same time increases the enzymes used in the anaerobic pathway in catalyzing the process of fat oxidation. The increased capacity of mitochondria allows for the process of fat oxidation since fats are broken down in the cell organelle. However, the claims fail to acknowledge the process involved and the condition required in for the process of burning body fats to take place. For example, body fats are usually stored as a reserved source of energy. The availability of carbohydrates makes it difficult for the utilization of fats to take place. This is due to the process by which carbohydrates will have to be depleted before the body starts consuming the fat stored.
However, other forms of training also contribute to the burning of body fats. In particular, resistance training and high-intensity interval training also offer an opportunity for burning fats. For example, weight-lifting is a high-intensity interval training that can assist in burning fat. Although fat becomes metabolically inert, lean muscles play a significant role in achieving the metabolic rate. Since increased volumes of muscles are associated with higher metabolism, the burning of fat occurs due to this effect. For example, weight lifting increases the metabolism rate leading to the need for the body to convert fats into energy. Also, it is important to note that high-intensity training combines both anaerobic and aerobic exercise. The combination leads to significantly increased metabolism levels which, in turn, lead to the burning of body fat.
My knowledge in this area is essential in dealing with issues to do with body fats, where clients are willing to hire a personal trainer to help them get rid with such fats. In my future training, I intend to use my current knowledge as a foundation to learn more about the various exercises that lead to positive outcomes as far as burning fats is concerned. Also, I look forward to learn more about different aspects of fat metabolism. My idea is to focus on understanding the pathway associated with fat metabolism. In doing so, I will be in a better position to assist other achieve their goals.
Blood Pressure Measurement
I recently engaged my friend in a blood pressure measurement. My friend recorded a systolic pressure score of 126 and diastolic pressure of 72 mmHg. In contrasted, my friend registered a systolic pressure of 142 and a diastolic pressure of 85. Systolic is the measure of blood pressure on arteries and vessels the heart beats while diastolic is the pressure exerted on the walls of arteries between heart beats and the heart is relaxed. Therefore, the systolic value is usually significantly higher than diastolic. Normally, diastolic range between 60 to 80mmHg while systolic range between 90 and 140mmHg. Anything below 90 is considered low blood pressure while scores higher than 140mmHg are considered abnormally high. This range is due to various factors such as age. For example, the values of both systolic and diastolic increase with age. Therefore, the good, fair, or poor range differs with age.
As part of the exercise, I was keen on involving my close friend who admitted trying to reduce weight in vain. In fact, his willingness to participate was motivated by the desire to lose weight. Therefore, as we shared a lot about our eating habits, exercise routine, and other lifestyle issues, I realized that blood pressure is linked to lifestyle. Firstly, the activity levels between us differed significantly. While I am actively involved in physical fitness activities, my friend admitted spending most of his pass time chatting on various social media platforms. He also expressed his dislike for physical activities although he plans to engage in at least one activity. From my assessment, the higher blood pressure correlated with his inactive lifestyle.
The lifestyle regarding what we eat also came up as a possible cause leading to the difference in blood pressure outcome. In my case, I always watch what I eat. My understanding about the various foods, the calories they contain, and what I need has always informed my decision on what to eat, when to eat, and how often I eat. Also, my desire to lead by example as a personal trainer has motivated me to take healthy meals always. In contrast, I noticed that my partner had a poor eating habit. First, he prefers fast foods since they save the time required for preparing proper meals. Therefore, I firmly believe that our lifestyle, especially our diet, is correlated to the blood pressure. My research on the same also showed the impact of stress on the blood pressure.
I intend to use the knowledge I have gained on blood pressure in my future training endeavors by engaging my clients finding solution from various avenues. For example, it would be meaningless to participate in strenuous exercises as a way of ensuring normal blood pressure without adjusting the lifestyle and stress levels. Hence, focusing on all possible causes of blood pressure leads to the best results since all the conditions are met for optimum body function.
