Cross Trainining Technique

Cross training: A technique in which exercising one part of the body increases the strength of a weak muscle on the opposite side.

In case of any accident, if any part of our arm or leg is injured, it is a common practice to support the injured limb with a special elastic band (sling) to keep the injured limb from moving.

However, this practice for a long time sometimes causes the muscles of the affected area to weaken and decrease in volume, and in this case it takes a long time for these muscles to recover.

However, medical experts are now researching the effects of 'cross training' for this.




According to experts, recent studies show that cross-training can reduce the loss of muscle mass in the unused arm.


This technique can increase the strength of the right arm by 20% and increase the strength of the weak arm by 10%.

 

The technique of cross-training was first discovered 100 years ago, over a but the mechanisms behind it are still not fully understood.


Researchers reviewed more than 100 studies and found that the average rate of cross-transfer between strength gains in trained and untrained muscles ranged from 48Cross training. A technique in which exercising one part of the body increases the strength of a weak muscle on the opposite side.



These changes may also be due to the activation of signals that control the movement of parts of the brain, such as inhibiting the movement of an area. In such signals, the brain gives movement instructions to only one side of the body. In addition, new voluntary activities or changes in activation in certain parts of the brain also help to activate weak muscles.

There are three types of voluntary muscle contractions:

1- Isometric muscle 

2- Concentric muscle 

3- Eccentric muscle

Isometric muscle force is equal to the weight being lifted. This allows you to lift a weight and hold it still, such as holding a dumbbell

Concentric muscle strength is greater than the weight being lifted, which is why you can lift or pull the weight while keeping it dynamic, such as lifting a dumbbell.

Eccentric muscle force decreases relative to the weight lifted. This allows you to lower or drop the weight you lift. Like lowering a dumbbell

Resistance exercises increase both muscle strength and endurance when the muscles work against a weight or force.

Learn to live with Water Scarcity

Image
  Learn to live with water scarcity Regions around the world are experiencing drought and water scarcity, even in places that once had abundant rainfall, and this situation will worsen as the planet warms. In 2018, nearly all water taps ran dry in the South African port city of Cape Town. Then it became the second largest city in the world suffering from severe water shortage. This problem still occurs. This year, communities 750 kilometers east of ' Nelson Mandela Bay' will find their reservoirs dry by July. The Cape Town administration has taken strict measures regarding water usage to avoid this 'Day Zero'. The city administration has increased water usage rates and fines and has worked with the agricultural sector to reduce water consumption and maintain soil moisture. Residents of the area will maintain a daily water consumption limit of only 50 liters or 13 gallons. Remember that one load of laundry can use up to 70 liters of water.

A Thirst for Economic Growth

Image
  Although socio-economic factors create water problems, they can be countered with better water management. Between 1961 and 2014, the rate of global freshwater withdrawal (whether from ground or underground reservoirs) increased 2.5 times. According to WRI, water demand for crop irrigation has doubled in the last half century and irrigation accounts for about 67 percent of water used. In 2014, industry requires nearly three times as much water as in 1961 and now accounts for 21 percent of total water use. Although domestic water consumption accounts for 10 percent of total water use, it has increased sixfold since 1961. And very little water is used for animal consumption. But crops grown for animal feed consume 12 percent of the world's irrigation system. That's why experts believe that by reducing the growing demand for animal meat, we can reduce the pressure on water resources. Hofstede says that this is the only way to solve the global water problems. "We use a lot ...
