A decurve bow is a bow that has arms curved or curled at the ends to turn towards the archer. This bow form reduces the strain on the bow when it is used, and the bow may be under no tension at all when strung, so that it can be kept ready for immediate use at all times. It also reduces the energy stored in the bow, and the speed of the arrow.
Nutritional rickets is an important cause of childhood genu varum or bow legs in some parts of the world. Nutritional rickets is due to unhealthy life style habits as insufficient exposure to sun light which is the main source of vitamin D. Insufficient dietary intake of calcium is another contributing factor.
The limbs store the kinetic energy of the bow – no energy is stored in the pulleys and cables. Draw weights of adult compound bows range is between 40 and 80 pounds (18 and 36 kg), which can create arrow speeds of 250 to 370 feet per second (76 to 113 m/s). In the most common configuration, there is a cam or wheel at the end of each limb. The ...
In archery, a recurve bow is one of the main shapes a bow can take, with limbs that curve away from the archer when unstrung. A recurve bow stores more energy and delivers energy more efficiently than the equivalent straight-limbed bow, giving a greater amount of energy and speed to the arrow .

Most bowfishing bows have little to no let-off and are typically designed for 40–50 pounds (18–23 kg) of draw weight. Some other bows can have as much as 120-pound (54 kg) draw weight. The crossbow is also sometimes used in this manner and has its own advantages, including the use of a reel. See Recreational fishing.
Zach and Tori Roloff’s 5-year-old son, Jackson, is “having a hard time recovering” following his leg surgery in December 2021 — and his parents are getting concerned. The Roloffs: A ...
When the bow is drawn, the sinew (stretched on the outside) and horn (compressed on the inside) store more energy than wood for the same length of bow. The strength can be made similar to that of all-wood "self" bows, with similar draw-length and therefore a similar amount of energy delivered to the arrow from a much shorter bow. However ...
