Summary of the First Article
The first article seeks to answer the question of whether aging is associated with increased inflammatory activity or not. From the article reading, aging is a leading factor in the progressive decrease of muscle flexibility and strength. When people exercise, the risk of cardiac emergency increases substantially. Several physicians have argued that those people who have grown old and intend to exercise ought to undergo exhaustive preliminary screening, including an electrocardiogram. It might be necessary if the individual purposes to embark on a very energetic competitive exercise. However, it is not desirable if older individuals desire to increase their regular daily physical activity.
Those individuals who are young cover the period from 20-35years of age, when physical performance and biological function reach their peak. Physical activity normally wanes during young middle-age, which is between 35-45 years, with a 5-10 kg accumulation of body fat. In the early old age, which is 65-75 years, there might be a slight upsurge of physical activity in an effort to fill free time as a result of retirement. By middle old age (75-85 years), numerous individuals develop some physical disability, and in the last stage, which is very old age, over 85 years, they turn out to be entirely dependent.
In the understanding of the article and in answer to the question of whether aging is associated with increased inflammatory activity or not, it is a fact that age-associated increases in systemic inflammation are associated with, and predictive of, many aging phenotypes. For instance, abnormally increased inflammation is usually connected to immune dysfunction, tissue dysfunction, neuronal problems, and metabolic syndrome. Inflammation is one of the defense mechanisms. It functions as the body’s usual way of defending itself against infection and injury. However, when it happens on a loop, it can result in damage that strains the skin cells and hastens the aging process. There are, however, wide inter-individual differences in functional status at any particular chronological age.
Summary of the Second article
In summary of this article, it aims to give information that exercising improves free testosterone in lifelong sedentary aging men. Since the effect of high-intensity interval training on systematic hormones in aging men is not studied well enough, this article seeks to investigate whether sex hormone-binding globulin, total testosterone, and cortisol were changed after HIIT in a cohort of 22 lifelong sedentary older men (Hayes, 306). In the reading of this article, exercising on a regular basis aids individuals to age more slowly and live healthier, more vigorous lives. It is essential in helping people live for a long time. Several research papers indicate that resistance to training can bring about an upsurge in testosterone production. Exercising has numerous advantageous effects on the body.
Apart from helping in weight loss, exercising can also improve the bone density and even the mood of a person, both of which can be negatively impacted by low testosterone. It is beneficial for main to exercise regularly since they can gain about two hours of life expectancy for each hour they exercise. When older men exercise regularly, it can raise testosterone because it promotes muscle building. The more muscle a person has the higher your testosterone levels. Men can boost testosterone naturally by exercising. Maximum advantage needs regular exercise over the years, but it does not signify going to the gym each day.
Advancing age is associated with a steady decline in circulating testosterone hormone, and the supposed role of exercise training on systemic testosterone hormone remains to be adequately defined. Exercise training improves free testosterone in lifelong sedentary aging men. Only 30 minutes of brisk walking each day will go a long way toward enhancing health. Low testosterone can affect a man’s muscle mass, mental health, energy, and more as he ages. It is essential to exercise regularly.
Summary of the Third Article
This article attempts to give an evaluation and analysis of exercising, protein nutrition, and aging. The research question in this article focuses on the way elderly people can decrease their chances of sarcopenia. One common thing is that protein intake and strength conditioning can aid in increasing muscle size (Evans, 3). This article uses the method of strength training through weight lifting. The variable is muscle mass because the muscle mass changes depending on how often the aging trains by lifting weights. From the article, aging is associated with notable changes in body composition. Sarcopenia, which is a process of skeletal muscle loss, is a prominent feature of these changes. Moreover, gains in visceral fat and total body fat content continue into the aging life.
The elderly individuals are the target audience in this article. The finding of this reading indicates that aging takes a big toll and transforms the body structure, which results in the increase of dietary protein requirements. The research backs up these findings because if old individuals strength train, they become less likely to have muscle mass loss. From the article, the cause of sarcopenia is probably a result of several changes that also happen with aging. They include changing endocrine function, reduced physical activity levels, increased dietary protein needs, and insulin resistance. Whereas a lot of elderly individuals take a sufficient amount of protein, several of them have a reduced appetite and consume less than the protein RDA, probably leading to an augmented rate of sarcopenia.
This study talks of its limitation in a way that elderly individuals do not have the same activity levels. It also demonstrated that the elderly use of protein-calorie supplements was connected to muscle mass gains and greater strength. The findings of this article can be applied to enhancing the hypertrophic response to weight exercises.
