Why Science Matters Does science sometimes seem dry and boring? Why do we need to learn about it? "Why Science Matters demonstrates" how the science we learn at school is important in every aspect of our everyday lives. Using case studies and investigations, the series describes the development of science and technologies that can improve our lives-or lead to new scientific challenges and controversies. In "Sports Science", we learn how sports and exercise science can benefit everyone, not just athletes. We findout about how the body responds to exercise, the role of nutrition and sports psychology in improving performance, how biomechanics can improve efficiency and reduce injuries, and see examples of training regimes. Learn about how the body obtains and uses energy during exercise, the ways in which fitness is measured, and the effects of stress, dehydration, and overtraining.
