The human shoulder is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons. The articulations between the bones of the shoulder make up the shoulder joints. "Shoulder joint" typically refers to the glenohumeral joint, which is the major joint of the "shoulder," but can more broadly include the acromioclavicular joint. In human anatomy, the shoulder joint comprises the part of the body where the humerus attaches to the scapula, the head sitting in the glenoid fossa[disambiguation needed.The shoulder is the group of structures in the region of the joint.
The shoulder has greatest range of motion of any joint in the body. Because of this mobility, it is at risk for injury or degenerative problems. The bones of the shoulder are the humerus (upper arm bone), clavicle (collar bone), and scapula (shoulder blade). The head of the humerus bone (the ball) is lined with cartilage that glides over the shoulder socket (also known as the “glenoid cavity”). The clavicle attaches the shoulder to the rib cage and holds the shoulder out from the body. The scapula is a large triangular bone located on the back side of the upper body, and it is connected to the clavicle through the acromioclavicular (AC) joint.
The front delts play a major assisting role in chest training, and even receive some degree of stimulation from biceps and triceps exercises like barbell curls and dips. Because of all the ancillary work they receive, front delts are often an overdeveloped item on many physiques. Over time, this can even lead to posture problems, as the person tends to adopt a 'slumped forward' stance. The medial, or side head, abducts the arm, meaning that it brings the arms out and away from the midline of the body. The side heads are only activated to a significant level when trained using specific isolation movements. Finally, the posterior, or rear head, extends the arm and produces external rotation. The rear delts are very much involved in back training movements such as chins and rows.
We hear it time and time again, the more exercise you do, the better it is for your metabolism, your body and your mind. Now, that's all well and good but what is less frequently discussed is the fact that many of us are training poorly - so poorly in fact that our exercise may not really be doing much at all. So, here are some of the most common exercise mistakes women make, and the easy ways to fix them.
Could HIIT be the king of all fat loss protocols? Inside are 10 amazing changes your body undergoes during HIIT that makes it so effective for fat loss.
By now I’m sure you’ve heard about high-intensity interval training (HIIT). HIIT combines short periods of intense exercise with short periods of rest. It has been purported to be one of the best exercise protocols for fat loss. But do you know why this is the case? Below I lay out 10 physiological adaptations your body undergoes when you do HIIT so that you can completely understand why it’s so effective for fat loss.
Scientists have discovered a new truth behind big muscles, turning 50 years of knowledge on its head.
Bulging biceps get their power from a mesh arrangement of cells rather than long ropes, detailed studies reveal. As muscles flex, tugging filaments fan out in a lattice, say the University of Washington team who made the breakthrough. This generates force in multiple directions, not just up and down the muscle, Proceedings B journal reports.
This aspect of muscle force generation has flown under the radar for decades and is now becoming a critical feature of our understanding of normal and pathological aspects of muscle.” And it's not just biceps that use this force - all muscles, including the heart appear to do it.
Prof. Thomas Daniel, one of the researchers, said: "This aspect of muscle force generation has flown under the radar for decades and is now becoming a critical feature of our understanding of normal and pathological aspects of muscle."
The basics of how muscle generates power remain the same - filaments of myosin tug on filaments of actin to shorten or contract the muscle. But myosin doesn't tug in one direction, as previously thought. Instead, it pulls at angles and this gives radial force.
The news will be of interest to bodybuilders who strive to max their muscle power, but could also help doctors treating heart problems. Michael Regnier said: "In the heart especially, because the muscle surrounds the chambers that fill with blood, being able to account for forces that are generated in several directions during muscle contraction allows for much more accurate and realistic study of how pressure is generated to eject blood from the heart.
"The radial and long axis forces that are generated may be differentially compromised in cardiac diseases and these new, detailed models allow this to be studied at a molecular level for the first time."
Today, people have become more conscious about being fit and healthy. Owing to this, they are spending huge money on various fitness equipments. Walking and jogging, on a regular basis, are one of the best ways to stay fit and healthy.
To burn fat, you of course need to get your diet in order, so eat animal protein and cruciferous vegetables with avocado or olive oil whenever you're hungry, use workout nutrition, and drink only water and green tea.
Once you've got your diet in order, you need to burn fatty acids by doing workouts that have a high metabolic cost, and the best way to do that is to add finishers 3-4 days a week.
“Many bodybuilders complain that they cannot feel their lats during workouts.
The problem is that most rely too much on their biceps and forearms—and not on their lats—to pull the weight.
A study from University of South Carolina Upstate (Spartanburg) shows that you can better target the lats with correct focus. The researchers had women perform the lat pulldown with just basic instructions or with verbal instructions on how to focus on the lats and minimize arm involvement.”
