NBA star Al Horford on Dec. 27, 2013 game against Cleveland was injured, after MRI test results showed that his right pectoral muscle tear.
Pectoral muscle tear, there are two cases, one is caused by excessive contraction for example pushed the limits by weight bench press, push up the process of tearing occurs. The other is caused by excessive thrust, Horford torn pectoral muscle this is the case.
The pectoralis major is located in the upper front thorax, starting from the medial half of clavicle, sternum and rib cartilage 1-6, bundle outward focus, beyond the humeral greater tuberosity ridge, as shown below:
Horford was injured in the process: its scrum when the pressure in the right arm and shoulder and arm on the other side jump competition for basketball, and the other after landing suddenly turned and lay down arms, resulting in downward pressure Horford force too late to recover the other side of the shoulder and arm this force makes Horford right arm swings back down quickly, causing its outer edge of the pectoralis major muscle hyperextension formed tear. It can be said Horford pressing down the other side of the force acting almost entirely on the outer edge of his chest, the rapid force can tear a man chest. Injured are in a position substantially circle below.
Now look at interactive: readers of this article to stretch your right arm straight back, you can feel the position of the figure circled a stretch then right arm straight conducted Charge, suddenly quick to swing behind the stretch ( Do not send the full, accidentally hurt yourself), just so that we understand few. Imagine if you have a shoulder under your right arm, your right arm straight hair with the full pressure of the shoulder, then suddenly lifted off the shoulders, you put the whole effort exerted himself what would happen? Moreover Huofu Derby Most readers have the power, but when the force endurance (body would fall under the right arm pressure force has some additive effect).
Horford injured Factors Summary:
1, fatigue. Has to first overtime segment, Horford has accumulated a fatigue. Fatigue will reduce the people to control the muscles.
2, Horford has good power. If a person is not big enough force, but also could not easily hurt themselves.
3, endurance action. Control muscle endurance than action on the ground to be difficult, and the ground itself downward force has a strength bonus.
4, fast action. Reader test, slowly chest thrust back hard to pull off, but when the fast force, if there is no control muscle strength, increases the chance of injury.
5, blocking force. That Horford put his right arm pressed against each other and, on the other side of the body Horford has a blocking effect, if the blocking effect suddenly taken away, it is likely to cause the force were injured, of course, this also depends on the force's ability to control the muscles.
Horford injured inspiration to other trainers:
1, in the training of muscle while increasing muscle control training and neuromuscular chain functional training, joint proprioception training. Light muscle training and the lack of the above-mentioned training, can also cause your stop or sharply when various explosive, own their own muscle strain, may also be the soft tissue sprain. Fast explosive, endurance and action against the project even more so.
2, fatigue careful to add, leave a force.
3, in the face of power barrier, pay attention to self-protection force when.
