Dehydration is a drag on human performance. It can cause fatigue and sap endurance among athletes, according to a 2018 study in the journal Frontiers in Physiology. Even mild dehydration can interfere with a person’s mood or ability to concentrate. Water is cheap and healthy. And drin

This study compared the efficiency and speed of the cross-over step to backward pedaling for defensive backs when covering a receiver. Abstract In American football, defensive backs guarding receivers use either the cross-over (CO) run or backpedal (BP) technique, but the efficacy of

Abstract: This study investigated the maximal sprint velocity kinematics of the fastest 100 m sprinter, Usain Bolt. Two high-speed video cameras recorded kinematics from 60 to 90 m during the men 100 m final at the IAAF World Challenge Zagreb 2011, Croatia. Despite a relatively slow r
