The article Why Muscles Don’t Break: New Research Offers Possibilities for MD Therapies explains in-depth the functions of the muscles in the human body. Throughout the article the author, Joana Fernandes, presents the extensive amount of research that she has performed regarding this insightful topic. She cites a study published in the Proceedings of the National Academy of Sciences, called “α-Actinin/titin interaction: A Dynamic and Mechanically Stable Cluster of Bonds in the Muscle Z-disk”. Essentially, the study explains that the reason muscles don’t break is due to the two binding proteins called a-actinin and titin. Fernandes utilizes evidence from the study to formulate her article and describe how these two proteins work together in unison to withstand a force of up to five piconewtons, “The experiment showed the bond between these two proteins is able to withstand a force of five piconewtons, a small force comparable to nearly one billionth the weight of a bar of chocolate” (Fernandes). As the article progresses, Fernandes analyzes how such small forces hold a muscle together for a lifetime and explains to the reader that this is possible because there is seven times more strands of a-actinin than titin. Undoubtedly, this article is pertinent to science because it contributes to the development of muscles in …show more content…
While this is a compelling topic I was curious to learn the scientific details behind this relatively new concept. Moreover, I was intrigued when I read that this discovery is an advancement in medicine, because it can lead to new ways in therapy. As a former soccer player I understand how important this discovery is to sports medicine as well. If research continues to prosper in this field like it has done, I believe that the future of the medical field is bright and this is all due to discoveries in science like this

“These things, in my judgment, work better than most scientists believe,” says Gary Wadler of the New York University School of Medicine, “the athletes figured out how well these work long before scientists.” (pg. 13)
Muscle analysis. The amount of astaxanthin in muscle in trout fed with a low fish oil diet was 6.3 ± 1.6 g per gram of muscle and in the case of the diet with a higher level this concentration was 9.7 ± 2.2 g per gram of muscle. Therefore, rising the proportion of fish oil in diet, a 54% increase in pigmentation can be obtained. A higher amount would be expected with a longer period of administration and further experiments will clarify this assertion. As our previous work has shown {Salvador, 2007 #7} carotenoid deposition in muscle was affected by the diet. In that work, trout were fed three different diets and muscle canthaxanthin deposition was higher when phospholipids were associated with fish oil in the diet.
Music rarely involves life threatening injuries to the practitioner. However, potential damage commonly hinders further practice, and can even halt it entirely.

One striking feature of this book is that each and every muscle in our body was explained by a separate chapter. For example, there is a chapter named 'Biceps',(arm muscle) which goes on to explain about; the muscle's anatomy, causes of dysfunction, pain pattern, assessment methods, various treatment methods including trigger point injections. Nobody discussed any human
Muscle activity. Muscle activity was recorded using a Bagnoli EMG system (Delsys, Boston, MA, USA) from 7 upper extremities muscles: flexor carpi ulnaris (FCU), extensor carpi ulnaris (ECU), extensor carpi radialis brevis (ECRB), triceps, anterior deltoid, middle deltoid, and upper trapezius using single differential electrodes. The muscle activity data were normalized to muscle–specific maximum voluntary exertions. The data acquired using a Motion Monitor data acquisition system (Innsport, Chicago, USA) which were sampled at 1200 Hz, and filtered using a Butterworth filter and notch filters (at 60 Hz increments).
1. Introductions Muscle tissues are one of the essential materials in human body, it plays a great role of human body, supporting not only external movement but also internal function, providing the force to help the organ 's function, for example, cardiac muscle tissue pumps the blood through the heart, making the circulatory system works fluently in human body. "Like the other collagen-based tissues which can evolve different hierarchical structures to meet their different mechanical needs"[1], the development of muscle tissues is analogous to this evolvement of mechanism, it can apparently change their quantity and quality through frequently physical activities and food intake, providing a corresponding strength to meet the "environmental change". To respond the "environmental changes," muscle tissue would be reconstructed by itself.
Muscles what are they and what do they do? Well muscles are responsible for many things but one of the main and most important functions of muscles is they’re responsible for movement; the muscles responsible for movement are your skeletal muscles, in order to move your muscles of course need to contact there are two types of contractions the first is Isotonic concentric contraction it is where the muscle shortens and then there’s isotonic eccentric contraction where the muscle lengthening. (skeletal muscles are a form of striated muscle tissue which is under the voluntary control of the somatic nervous system. Most skeletal muscle is attached to bones by bundles of collagen fibers known as tendons). they’re attached to your bones and are controlled
Skeletal muscle is necessary for locomotion and the maintenance of posture. Without skeletal muscle, which operates under voluntary control, humans would lack the ability to do the most basic of tasks such as or standing or walking. A muscle is comprised of numerous muscle fascicles, which consist of muscle fibers. These muscle fibers are composed of muscle fascicles, which The basic unit of skeletal muscle is the sarcomere, which is comprised of myofibrillar proteins myosin (thick filament) and actin (thin filament) which consists of Troponin and Tropomyosin, two important proteins necessary for muscle contraction.1 Skeletal muscle contraction occurs as a result of excitation-contraction coupling. Upon the arrival of a nerve
Insufficient Calories Consumed The human body requires a MINIMUM of 1200 calories per day to function. If you consume less than that (on a crash diet for example), your body will interpret that as being in a famine and will reduce your metabolism (the bodies ability to burn calories) in order to protect itself and be able to survive for longer. This will stop it from burning fat stores. Solution: Maintain a reasonable calorie consumption. Use a BMR (Basal Metabolic Rate) calculator to determine how many calories your body requires per day to maintain itself. Once you have determined approximately how many calories your body requires to operate, reduce you calorie consumption to 500-700 calories less than that without going under 1200 calories.
The muscular system is fundamental to human life, without the skeletal muscles mobility and balance would be impeded. The purpose of this lab is to study the physiological properties of the skeletal muscle by isolating the gastrocnemius of a frog and running it through a series of tests. These tests will help us identify the minimum and maximum strength of stimulation (threshold and plateau values) that will evoke a muscle twitch. The force generated by muscles is dependent on the total number of muscle fibers, the number of activated fibers also depend on frequency and stimulation.
One indicator of life that has continually been examined is motion; whether it has been external or internal it is better understood in the body as muscles. Muscle analysis and locomotion dates back to ancient history. Today there is a more in depth modern understanding of muscle types, movements and contractions. Both scientists and everyday fitness enthusiasts debate over knowing how different types of motion and muscle contractions effect muscle function and structure. Interestingly there are studies that either support or dispute the various types of muscle contractions for building strength and muscle hypertrophy. Every day we use our muscles and with an in depth look into how they work will lead to understanding which way to train our muscles for optimal results.
