Pollock protein and hypertrophy.


Fish are one of the elements of the diet of many weight-loss people, including bodybuilders preparing for the start. In one of the previous studies, Kawabata F. and WSP. proved that the fish protein improves the lipid profile and reduces the growth of fat tissue by affecting muscle hypertrophy and increasing energy expenditure.

In the next study, it turned out that the fish protein (Theragra chalcogramma or pollock) increases the mass of fast-twitch muscles, reduces the level of triglycerides in the liver and serum glucose levels compared to the casein diet after 6 or 8 weeks of feeding. 

A high fat diet based on casein or fish protein was used. The mixture consisted of 200 g / kg casein, 3 g / kg cystine, 257 g / kg maize starch, 200 g / kg sucrose, 30 g / kg soybean oil, 215 g / kg lard, 50 g / kg cellulose, 35 g / kg of mineral AIN-93G and 10 g / kg of a mixture of vitamins AIN-93 containing 25 g of choline triflate / 100 g. 

In addition, fish protein has increased the expression of fast twitch muscle markers and glucose transporter in the muscle. These results suggest that the fish protein induces hypertrophy of the fast muscle, and increasing the basic energy expenditure due to muscle hypertrophy and increasing the uptake of glucose in the muscles has reduced the level of lipids in the liver and the level of glucose in the blood. 



The pollock protein has a beneficial effect on body composition, lipid profile and glycemia. Therefore, it indirectly can prevent type II diabetes and support weight reduction. In rats, the intake of fish protein may affect the proportion of muscle fibers (it is not known whether these changes will be so intense in trained athletes).
