Photographs serve many purposes, and nearly everyone has a camera, but some photographers see deeper and show more than others.  32  artists, they are deeply concerned with form and shape as they touch the human spirit. Dorothea Lange was such a photographer. 

    Dorothea Lange,   33   in 1895, began her career as a commercial photographer. But her finest pictures recorded the suffering of poor people and were taken during the hard years of the American Depression in the 1930s. Her photographs helped to  34  the government into taking action to improve the conditions in which they lived.  35  she made thoughtful photographic studies of the Japanese Americans who were in prison in America during the Second World War, when Japan and America were enemies. She also photographed many other people, both great and  36  . When she died in 1965, her photographs formed part of collections all round the world. 

       Technology is continuously changing the sports industry for the better. Electronic devices known as sensors can detect changes and provide instant information about the health and movements of the athlete. Technology has changed the way some athletes train by live tracking the athlete’s performances, perfecting the athlete’s movements, and preventing sports injuries.

       Using sensors worn by the athlete, sports trainers can measure and track performance in real time. Nearly everything about the athlete can be measured, from breathing and heart rate, to sweat and temperature. The real-time information can help the trainer determine what aspects each athlete needs to focus on more. During practice, the trainer can read the data and decide when it’s time to rest, stretch or train harder. In the past, however, the practice session would be recorded, and the athlete’s performance would be judged later after the practice.

       Technological tools also provide a lot of information about the athlete’s movements. These tools can measure the exact position, distance, and speed of the athlete. The sensors on a swimmer’s body, for example, provide data on movements like dive angle and leg movement. Observing these movements allows the trainer to help athletes perfect their performance.

       The most important effect of technology on sports training is that injuries have been sharply reduced. Training software can assist trainers to keep watch on all aspects of training, including diet, energy, and sleep. This helps prevent fatigue and self-created injuries during practice.

       Technology allows athletes to not only get the most out of their training but also stay injury free. Sports technology will undoubtedly increase the athlete’s potential.
