Oil-Rich Fish. Oil-rich fish are so called because the oils are distributed throughout the flesh of the fish. Mackerel, herring, salmon and trout are common examples. Occasionally you will find fish classified in a different way: Demersal and Pelagic Fish.
For other uses, see Springbok (disambiguation) . The springbok (Antidorcas marsupialis) is a medium-sized brown and white antelope-gazelle of southwestern Africa. It is extremely fast and can reach speeds of 88 km/h (55 mph) and can leap 4 m (13 feet) through the air.The common name springbok comes from the Afrikaans and Dutch words spring = jump and bok = male antelope or goat.pringbok footprints are narrow and sharp, and are 5.5 cm (2.2 in) long. springbok are distinguished from gazelles in that they only have two premolar teeth in each side of each jaw, instead of three, and therefore a total of twenty eight teeth, rather than thirty.
What I mean by that profound statement is that if you ever hope to walk a fast 5k or 10k (or marathon, for that matter) you must first be able to walk fast for forty or fifty meters. A little basic algebra: Walking speed is a function of stride length times stride rate. So stride length certainly cant be ignored, but you wont get anywhere in a hurry without a high stride rate. You simply cant walk very fast without taking a lot of steps per minute, no matter how long your strides are.
