The force of gravity affects all "bodies" in the universe. How well each human falls into the imaginary line of gravity determines the energy they must have to expel to live within this force.
The ideal axis for obtaining the greatest balance is one that is a strait line through the center mass of the body. This line should be identical to the one between the gravitational force between the body and the earth. The human body has adapted over many generations and there are markers that will show where a strait line should form to be properly aligned. This imaginary line connects points at the top of the head, middle of the ear, middle of the shoulder, midpoint of the hip joint, center of the knee joint, and center of the ankle joint.
Finding the angles that this line forms from unevenness will explain some things about the amount of energy and mobility this person spends to stay upright. If a person is not consciously holding their muscles to stay up, they must have chronic tension in their muscles to even themselves out. Over time this tension has been programmed into their brain and the connective tissue has been bundled up to help hold the tension. This tension has most definitely limited mobility of the antagonist muscles because they must now use extra force to move. These tensions are most likely formed from the overall function of the individual. For example, if a person is a shot-putter they will build up connective tissue to reinforce themselves from the large amount of torque placed on their bodies outside of their Center of Mass. Over time, their body will adapt to resist the forces its put on it but outside of shot-put, those tensions will remain as part of the person. Eventually, the chronic torque that the tensions of the muscles put on the body will deform the lines of symmetry and be detrimental to the person.
When people lift weights, it is almost impossible to isolate the lifting to a specific muscle due to the body's make up and connections in the brain. Phisiologicly, there are limitations to each muscle. When an isolated lift is attempted and one muscle can't do the job and more are called in that might not act directly on the lift but help in some way, it is called recruitment. Recruitment generally involves using more superficcial muscles than inferior ones and will result in a greater torque beacuse of this.

In lab, isometric handgrip strength was tested. Isometric strength refers to the type of force that occurs when muscles generate force, but its length remains unchanged. This can also be called a static muscle contraction. A static contraction occurs when one tries to lift an object that happens to be heavier than the force applied to the muscle or a static contraction occurs when one supports the weight of an object by holding the object steady with the elbow flexed. In both of these examples, the person feels their muscles tense but the joint does not move (Kenney, Wilmore, & Costill, 2012). Handgrip strength reflects the importance for successful performance in activities of daily living and occupational activities (Beam &

As we have learned through our reading, most all bodies skeletal muscles are made up of primarily three types of skeletal muscle fibers, but their proportion differs depending on what action the muscles is doing. For example, type I fibers such as muscles of the neck, back, and leg have a higher proportion. According to Quinn (2014), type I muscles are slower and more effective, they tend fire a lot slower than fast twitch fibers and they fatigue at a much slower rate. Hence, slower twitch fibers are pronounced at helping athletes run marathons and bicycle for hours. Shoulder and arm muscles are not always active but are intermittent in their use; these muscles tend to have a larger amount of tension for uses in throwing and lifting. These muscles have a combination of both type I and type II B fibers. These fast twitch fibers use anaerobic metabolism to create energy and are the "classic" fast twitch muscle fibers that excel at producing quick, powerful bursts of speed. These muscles are used in events such as 100m sprint, basketball, soccer and football. Since this muscle fiber fires at such a high rate of contraction it will fatigue much faster and will not last long before needing to rest.

Weight lifting is a broad term used to represent a vast number of actual exercises and styles. Weightlifting can be broken down into weight training, bodybuilding, fitness lifting, isometric training, resistance training, and athletic training. Although they posses similarities, often their objective separates them. Weight training generally means the pursuit of getting as strong as possible, and uses dead weight such as dumbbells and barbells. Bodybuilders have the goal to get the largest muscle mass and often times have a very small percent body fat. Fitness training or endurance training is often performed with low weight and high repetitions to build muscular endurance and general, non-athletic fitness. In isomeric training, the muscles and joints don't...
Many of us have some kind of postural deviation which can affect our performance as a result of which our bodies would not work at maximum efficiency. A faulty posture can also lead to back problems. Such faulty
The focus of this paper is mechanically and automatically break down the deadlift. It focuses on the four phases of the deadlift (The lift off, pull through, the lockout, and the lowering phase) as well as the muscles involved in lifting and lowering the load. The sole purpose of the deadlift is for health and fitness. It is a core lift that works nearly every muscle in the body. Muscles from the lower and upper extremities will go through a period of flexion and extension when moving through the phases. The deadlift should be performed safely, and with proper form to avoid injury. This paper shows and demonstrates the proper form of the deadlift. There are also a number of forces acting on the load and the athlete. Gravity and external forces will be an active part of lifting the load. Images and tables are provided in the paper to better understand the movements and muscles used when performing the deadlift.

They both use weights, but in different way. The idea of bodybuilding is how they lift the weight and they focus in a small amount of weight which is not very heavy. The weight that they’re going to lift or use in exercising machine, should match with their body and ability. Their goal isn’t to lift heavy weights, but the goal is having a well-proportioned body. “You can actually lift about 20 percent less weight than you can hold;conversely, you can lower about 20 percent more weight than you can hold” (Westcott 13). This means we don’t have to lift too many weights because we can get a well-proportioned body by using a small amount of weights with many repetitions. This kind of exercising makes the body very attractive by illustrates body 's detailing. We hold the appropriate weight slow and concentrate to give muscles the oxygen that it needs to give the muscles good form. In powerlifting the most important thing is to lift very heavy weights because that is the goal of it. They always talk about amounts and weights. Also, powerlifting doesn 't give the body a good shape because they need to be very fat to be able to lift the very heavy weights. “I’m not saying all powerlifters are fat, but they do tend to carry more overall weight simply because they’re missions has little or nothing to do with how they look”( Stallworth) . It is hard to say all powerlifters are overweight, but most of
This workout will assist with people’s everyday life by augmenting muscular endurance. An elevated muscular endurance will be less prone to muscle strains and tears because of the resistance they have developed, extended workout times, and a better stamina from the repetitions of lifting weights (“Benefits of Muscular Endurance”). Everyday life will be eased as it is easier to lift heavy items; the exercise overloads your muscles which challenges them so that they must adapt and therefore get stronger to meet the challenge of lifting those more hefty items. "To make a muscle grow, you must force it to go beyond its capabilities. The most potent way to apply that force is to train to failure. Training to failure means...the muscles are forced to grow stronger and bigger," says Nasser El Sonbaty who has body built for many years. With this easier way of doing things, people can get daily chores and activities done more quickly and efficiently which will also decrease stress levels tha...

Having good posture helps ensure that the entire body is properly aligned, while the tension in the ligaments and muscles are properly distributed. In addition, maintaining good posture is a way to keep body parts in their proper positions with minimal stress and more comfort. Maintaining a good posture

“The experience of weight is through that counteracting force of the ground pushing back on you as you are pushing down on the ground, because gravity is pulling you down. If you are in a spaceship you do not feel weight because you do not have the ground pushing up against you". (2)
