While genetics play a large role in one's ability to sprint, [90] [91] [92] athletes must be dedicated to their training to ensure that they can optimize their performances. Sprint training includes various running workouts, targeting acceleration, speed development, speed endurance, special endurance, and tempo endurance.
The record is 44.72 km/h (27.78 mph), measured between meter 60 and meter 80 of the 100 meters sprint at the 2009 World Championships in Athletics by speed. [4] [5] (Bolt's average speed over the course of this race was 37.578 km/h or 23.35 mph.) [6] Compared to quadrupedal animals, humans are exceptionally capable of endurance, but incapable of great speed. [7]
The fastest human footspeed on record is 44.7 km/h (12.4 m/s; 27.8 mph), seen during a 100-meter sprint (average speed between the 60th and the 80th meter) by Usain Bolt. [ 86 ] Speed over increasing distance based on world record times
The second half of the test involved subjects performing a 100-m sprint on a man-made track using radar to measure the forward speed of runners to create velocity-time curves. The main result of this study showed that the force application technique (rather than simply the total amount of force applied) is the key determinant factor in ...
Fartlek is a middle and long-distance runner's training approach developed in the late 1930s by Swedish Olympian Gösta Holmér. [1] It has been described as a relatively unscientific blending of continuous training (e.g., long slow distance training), with its steady pace of moderate-high intensity aerobic intensity, [2] and interval training, with its “spacing of more intense exercise and ...
However, beyond a certain point, negative consequences might occur. Older male runners (45-55) who run more than 40 miles (64 kilometers) per week face reduced testosterone levels, although they are still in the normal range. [34] Running a marathon lowers testosterone levels by 50% in men and more than doubles cortisol levels for 24 hours. [35]
The optimal amount per week was 1 to 2.4 hours, the optimal frequency was less than or equal to 3 times per week and the optimal speed was "slow" or "average". [15] A recent meta-analysis on running/jogging and mortality, including more than 230,000 participants found that runners were at 27% lower risk of death than non-runners, during 5.5-35 ...
For sprints, World Athletics maintains that world records and other recognised performances require: a wind assistance of not more than two metres per second (7.2 kilometres per hour (4.5 mph)) in the direction of travel; fully automatic timing (FAT) to one hundredth of a second; and no use of performance-enhancing substances.
