It was this accumulation of grievances that led to the burst of the Mongol attack on Islamdom from 1200 that culminated in the sack and slaughter at Baghdad in 1258 under Hulagu Khan who was egged on to this path by his Nestorian Persian Christian wife.
Type I muscle fiber is also known as slow twitch oxidative fibers. Muscle fiber types can be broken down into two main types: slow twitch (Type I) muscle fibers and fast twitch (Type II) muscle fibers.Type I fibers are used in lower-intensity exercises such as very light resistance work aimed at muscular endurance and long-duration aerobic activities such as 5K and 10K runs.ype II muscle fiber is also known as fast twitch muscle fibers. These fast twitch fibers can be further categorized into Type IIa and Type IIx fibers, which are also known as fast twitch oxidative and fast twitch glycolytic, respectively.
Skeletal muscle fibers can be classified as red fibers, white fibers or intermediate fibers. Red fibers are smaller in diameter; white fibers are larger in diameter. Red fibers have more mitochondria than white fibers. Red fibers make up slow-twitch muscle; white fibers make up fast-twitch muscle.
