Bear Size ~

Here is a portion of that site information: quote - Muscle mass is similar between the prime bear and the six­year subadult bear, with average muscle mass percentage levels differing at a rate of 1.38±0.24%. The muscle mass of the three year old bear was relatively low due to its low total weight, and the muscle mass of the oldest specimen concurred with the relatively high amounts of Ib fibres: the densest muscle fibres discovered in mammalian and reptilian bodies so far. Thus, the expected muscle weight of the post­prime aged bear should exceed that of the prime bear, even though the muscle volume is slightly higher in the prime aged bear. The maximum percentage of Ib fibres in the post­prime bear slightly, by 0.9%, exceeds the maximum percentage of IIa/x and IIb fibres in the prime bear, thus producing this result. Muscle density is far­exceeding within the oldest specimen also due to the over­accumulation of dense Ib fibers. In conclusion, no significant evidence provided any leads towards increased muscle strength deterioration or muscle mass deterioration in post­prime brown bears, yet evidence had been found of increased muscle volume deterioration in post­prime brown bears as. The brown bears who were experimented on were shortly released back into their respective locations within Yellowstone National Park after the study commenced. These findings suggest that brown bears, if not all bear species as a whole, are able to retain their muscle mass and maximum muscle strength well past their prime years, unlike most other animals.  Reply
