Walk around any gym, and you’ll see everyone carrying a water bottle. We all know we're supposed to drink water when we exercise, but why? Here are some of the most important reasons:
Walk around any gym, and you’ll see everyone carrying a water bottle. We all know we're supposed to drink water when we exercise, but why? Here are some of the most important reasons:
1) Water is critical to maintain healthy joints. Surrounding your joints is a thick, water-containing substance called synovial fluid, which lubricates the bones’ cartilage (shock absorbing material at the ends of the bone). Synovial fluid ensures smooth movement of bones when they rub against each other. When we exercise, we lose water through perspiration. If we don’t hydrate sufficiently, there is less water in our synovial fluid to keep the joints healthy.
2) Water affects our digestive system. Drinking adequate amounts of water helps to improve the transporting of nutrients from the bloodstream to muscle cells, and the excretion of waste products. Typically, weight trainers consume more calories than the average person, making adequate water consumption even more important.
3) Water helps reduce fatigue. Research has shown that a loss of 2 or more percent of body weight from perspiration is connected to a drop in plasma volume (Plasma is the liquid which carries blood cells and is almost all water). With less plasma moving through the body, the heart works harder to get blood and its nutrients circulated. This can also cause muscle cramps, dizziness and fatigue. With a 2 percent loss of water, the body is already in a state of dehydration. And dehydration will always cause your exercise performance to suffer.
