The back muscles, including the deep back muscles of the vertebral column, are responsible for many movements such as back extension and extending and rotating the trunk. The trunk acts as the transmitter and supporter of most arm and leg actions. The vertebral column also plays an essential role as a shock absorber for landing and takeoff actions. Excessive, uneven stress on the spine or sudden movement while in an unfavorable position may lead to back problems.
For athletes, back complaints may be due to wear and tear caused by improper positioning or forward tilting of the body. Disc pressure varies according to body position relative to external stress. Stress on the spine increases during lifting in standing or seated positions or when the upper body swings, such as in upright rowing or elbow flexion. Sitting produces greater disc pressure than standing; the least stress occurs when the body is prone such as in bench presses or pulls.
In many exercises that use the back muscles, abdominal muscles contract isometrically, stabilizing the body. The Iliopsoas. The iliopsoas is an essential muscle for hip flexion and running. Though not large, it is the most powerful hip flexor, responsible for swinging the legs forward during running and jumping. Sports performed on the ground require a well-developed iliopsoas. Exercises such as leg and knee lifts against resistance are key to training this important muscle.
Law Number Four: Develop the Stabilizers Prime movers work more efficiently with strong stabilizer or fixator muscles. Stabilizers contract, primarily isometrically, to immobilize a limb so that another part of the body can act.
For example, the shoulders are immobilized during elbow flexion, and the abdominals serve as fixators when the arms throw a ball. In rowing, when the trunk muscles act as stabilizers, the trunk transmits leg power to the arms, which then drive the blade through the water. The better the placement of steel to minimize how far a crane has to swing, boom up or boom down is a huge time saving factor.
How far a detail crew has to go to get the steel they are installing needs to be taken into consideration.
The placement of deck on the structure to minimize how far the decking crew needs to drag deck is also crucial for time savings. Always make it a point to unload steel in the areas that it needs to go in when possible to minimize how many times the steel has to be moved. Make it a point to work with them to get the steel as close as possible due to the fact that moving steel around after it is unloaded cost an Erector money that does not need to be spent when the time is taken in advance to coordinate where the most optimal places are to lay down the steel.
I have been doing digital takeoffs since and have developed a pricing tool actually much more than that called the Steel Erection Bid Wizard. I have helped over Steel Erectors to make the transition and would love to help you as well. Give me a call anytime. U Won't Forget Me. You Never Know. This Is the Summer. In Action. Fly to Be Free.
