Within 5-6 days, crabs migrate אי חג המולד From their abode in the rain forest to the ocean - a journey of 5 km - to mate. During the annual migration of the Christmas Island land crab it manages to sustain aerobic movement for 12 hours a day compared to only 10 minutes during the resting season when the muscles rapidly become anaerobic. This seasonal transformation, to muscle with endurance and repetition, is essential for the crayfish migration.
How do they get in shape so quickly? To find the answer, the researchers went to Christmas Island - Christmas Island in Australia - a small island where 1,500 residents live. The island is located in the Indian Ocean, 2,360 km north of the city of Perth, 500 km south of Jakarta in Indonesia. The island is unique in the types of plants and animals that live there and 65% of its area is dedicated to a nature reserve.
For research, the scientists collected muscles from the legs of the crabs during the migration and 6 months before, when the crabs were resting in the rain forest. The working method used by the researchers was the use of gene expression libraries, one from muscle during the resting period and the other from muscle during the migration period. Genetic analysis revealed significant differences in the expression of 14 genes between the two samples - according to A report by the group of researchers in the May issue of the Journal of Experimental Biology. These changes helped the crabs prepare their muscles for the long and arduous journey by changing the way the muscles produce energy. The activity of genes in crabs at rest helps the muscle fibers to carry out anaerobic metabolism, which does not require oxygen and is suitable for short-term effort. On the other hand, the expression of genes in migratory crabs encourages aerobic metabolism, which requires oxygen and is particularly suitable for activities that require high endurance and effort. Changing muscle metabolism, by changing gene expression, allows crabs to move very quickly from a "resting" state to a "migrating" state.
It's a shame that with us, humans, the mechanism doesn't work like that and to get in shape you have to... exercise.

For sure.. that they invent a ball that turns you into Brad Pitt with dice...
After all..thinking about it..it is quite realistic in the next 20 years
It doesn't work that way for us, but maybe we can make it work that way?
