IntroductionFitness is an important component of a successful swimmer. Race distance and stroke are components of fitness that contribute to the building blocks of a good swimmer. Fitness tests used to access a swimmer should also reflect the range of fitness components and the interpretation of the results should also be relative to the importance of each of these attributes (Ginn, E., 1993). In addition to the high level of skill required to be a successful swimmer, there are also several components that represent a swimmer's relative strengths and weaknesses. A swimmer's body size and shape requires them to be tall and lean. A swimmer's body type can have a lot to do with buoyancy. The composition of body fat causes body weight to be pushed down onto the water; the water then presses upward causing the swimmer to float to the surface. Usual anthropometric measurements for swimmers include height, weight, sitting height, arm span, hand span, and body fat using skinfold measurement (Ginn, E., 1993). A swimmer's reaction time is equally important in a short or long distance event. Within a competitive environment, starts can account for up to 26.1% of overall race time in sprint events (Cossor and Mason, 2001) and have been shown to impact performance in almost all styles and styles. distances (Mason and Cossor, 2000). . The ability to improve a swimmer's start can be attributed to technique and improved power. Strength and power are components designed to deliver explosive movement off the starting blocks and provide the ability to execute quick, powerful turns. There are specific land-based tests that can evaluate a swimmer's strength and power. A vertical jump test is ideal for measuring explosive power in your legs.

These sets are usually performed once a week within an eight-week training program. Training intensity ranges from 90 to 100% of an athlete's maximum intensity with a heart rate level above 180 bpm. Repetition training: Involves swimming a series of repetitions of a distance with a short rest interval long enough to allow for almost complete recovery. The main goal of this type of training is speed. Examples of repetition training are: 4 x 200 meters with 4 minutes of rest and 6 x 100 meters with 2 minutes of rest. Repetition training sets are usually performed once a week within an eight-week training program. Training intensity ranges from 90 to 100% of an athlete's maximum intensity with a heart rate level above 180 bpm.
