When people do exercise or play sport, their physical condition changes in various ways. Good changes help build physical strength and prevent lifestyle diseases. But if the physical demands of such activities exceed a person’s physiological limits, they trigger extreme fatigue and disorders, factors that can cause injuries. Our laboratory analyzes how physical functions respond to body movements and physical activity. The results are used for promoting good health, elucidating causes of injuries and disorders, and crafting measures to prevent injuries.
