Isometric exercises to improve strenght

Image
Bridge / Side Plate Lie on your side and press with your arm. Form a bridge with the arm extended and hold for 10-30 seconds. Repeat 2-3 times. Exercise of 100 Breathings Lie on your back with your arms at your sides. Bend your knees 90 degrees with your thighs perpendicular to the floor and raise your head and shoulders. Take 5 short breaths followed by 5 short breaths. At the same time, lift your arms off the ground and shake them in unison in short strokes. Repeat 10 times for a total of 100 breaths. You can also extend your legs as time passes, working more angles. Isometric Flexions Stand in the middle of a flexion path and hold the position for 10-30 seconds. Repeat 2-3 times. Isometric Shoulder Elevations Stand up, lift a dumbbell or other light weight directly to the side. Hold the position 10-30 seconds with the arm parallel to the floor or until the arm goes down through fatigue. Repeat 2-3 times and change arms, can also be done with both arms at the same time. ...

2. Lipids or fats: Like carbohydrates, fats are used mostly to provide energy to the body, but also essential for other functions such as the absorption of some vitamins, hormone synthesis and as an insulation material and internal organ filling. The main function of lipids is the energy reserve. They are present in vegetable oils, which are rich in unsaturated fatty acids, and in animal fats. Although the group of lipids belongs to a very heterogeneous group of compounds, most of the lipids we consume come from the group of triglycerides. They are made up of a molecule of glycerol, to which are attached three fatty acids of more or less long hip. In the foods we normally consume we always find a combination of saturated and unsaturated fatty acids (called "good" fat). Saturated fatty acids are more difficult to use by the body, since their possibilities of combining with other molecules are limited because all possible link points are already used or saturated.

Do you want to know how muscles work?

Introducing video: How our muscles work Muscle contraction is produced by an interaction of the protein molecules of actin and myosin, which in turn occurs due to the sliding between thick and thin myofilaments, this sliding causes a decrease in the amplitude of band A and zone H. Calcium (Ca) is the link between excitement and contraction of a muscle. The sarcoplasmic reticulum is specialized for its storage and release of calcium through the T system. When a nerve signal arrives at the muscle cell, a release of calcium is initiated into the fluid surrounding the filaments from special storage vesicles in the reticulum Sarcoplasmic, when combined with troponin, initiates the elimination of an impediment for a potential interaction between the actin and myosin filaments. In any case, the tropomyosin, which in the resting muscle has turned off the active sites of actin, can now activate them; In turn the actin can activate the ATP hydrolysis of the myosin heads. This allows ...

Descent of gullies. Part 2 Technics.

Image
Continuing the first part of descent of ravines ... To carry out a descent of ravine, we must have the necessary knowledge of the environment and techniques of descent by ropes that we must carry out for a correct practice, without incidents or accidents that compromise the safety of others and our own. For this we will carry out the explanation of all the technical knowledge that must be kept in mind when making a descent. USING THE DESCENTER Purpose: To use this element as a brake for the descent and in case of fall. The correct positioning must be chosen to avoid accidents when the rope is released. http://www.naturavertical.es/uso-basico-ocho-doble-sdf8/ Another dangerous variant is the classic mounting system, which tends to form the lark knot in the case where the descender comes into contact with a rocky ridge. DECLINE FROM A VERTICAL Failure to check the descender can lead to the descent with the eight crossed in the locking of the car...
