The system being developed by the UK company Hawk-Eye, would give a definitive decision on whether the ball had crossed the line. The Hawk Eye uses a camera taking 600 frames a second on the goal-line, with the information is analyzed by computer and sent to the referee's headset or a device on his wrist.

         In this case, it is enhanced video review, rather than the ball tracking technology as used in other sports. The 2020 US Open tennis implemented the next level Hawk-Eye Live, which made line calls in real time.

        Technology use in sports is increasing rapidly, though the sport of football/soccer has been slow to incorporate some forms of technology that other sports have. This article will discuss the use of technology to determine if a ball has crossed the goal line, one way that technology can greatly assist in football.

Fitness for Football

       Aerobic endurance fitness is one of the most important physical fitness attributes for soccer players. Players need to be able to maintain a high level of intensity throughout the 90-minute game. Another very important fitness component is anaerobic fitness, which means running speed and particularly repeat sprint ability. 

Fitness Tests

       In football, aerobic fitness is one of the most important attributes, closely followed by anaerobic fitness (running speed and repeat sprint ability) and agility. 

Body Fat

Body fatness affects the football player's ability to move freely around the field, and the extra weight will increase fatigue. Body fat can be measured using the skin fold method. If this is not available, monitoring body weight changes is an alternative to give an indication of body fat changes, assuming no change in muscle mass.
