The aquatic running described here requires participants to wear specially designed aquatic workout clothing and then run in waist-deep water. The purpose of wearing this gear is to help the body maintain a slight forward lean and enhance buoyancy to prevent choking on water. This is a highly trendy yet very practical fitness activity. Running in water creates significant resistance, which provides better exercise for the body and accelerates metabolism; it helps burn off excess fat, thus helping maintain a slim figure—making it ideal for those looking to lose weight. For individuals who are relatively thin or frail, this activity can easily stimulate appetite due to increased hunger, thereby improving digestive function effectively and enhancing overall physical health.
Here are four benefits of aquatic running for the human body.
1. Accelerating the body's metabolism
Because water provides more resistance than air, running in water requires more effort than running on land, consuming more energy and oxygen, which greatly speeds up the body’s metabolic rate. At the same time, various tissues and organs must work faster to adapt to the movement frequency; blood circulation is accelerated, which helps dilate blood vessels and increase their elasticity; the heart also gets an excellent workout through the repeated cycle of contraction and expansion. While running in water, the chest cavity experiences greater pressure, which means breathing intensity must increase accordingly, boosting lung capacity to counteract external pressure—thus exercising lung function.

2. Improving the body’s reaction ability
Maintaining balance in water requires certain skills and the coordination of various body parts; any disruption can make it difficult to stay balanced for long. Therefore, those who regularly engage in aquatic running typically have better reaction abilities and improved limb coordination.
3. Effectively preventing various diseases
The temperature of water is lower than that of the human body, so the metabolic rate must increase to prevent body temperature from dropping too much. Water pressure is greater than that of air, requiring more blood supply during exercise. This can lead to an increase in high-density lipoprotein (HDL) in the blood. Studies show that HDL can effectively reduce the risk of heart disease and coronary artery disease. Additionally, as older adults tend to lose calcium from their bones more quickly and are prone to osteoporosis, underwater running helps prevent calcium loss from the body, thereby reducing the risk of osteoporosis.
4. Promoting smoother skin
Since there are fewer obstacles in water and thanks to the buoyant force and the protection provided by the workout clothing, various types of injuries can be effectively prevented. At the same time, the friction between the body’s surface and the water helps boost blood circulation, making muscles more elastic, joints more flexible, and the skin smoother and more delicate.
