Thaw outdoor sports fields
What is thaw?
After the hard frost always comes the period when the snow and ice start to disappear. Just then we should be careful and not rush onto the sports field or tennis.
When we are in a period when it is freezing at night and above zero during the day, we experience “thawing. This is a phenomenon where the thawing water cannot sink down through the still frozen layer, which is underneath. As a result, the thaw water does not reach the drainage system. Right now we advise against entering the sports field or tennis court
Damage lava foundation and consequences
Entering the field too soon may cause the topsoil and a portion of the lava foundation to become unstable, and there is a chance that small dents may develop in the foundation.
Also, due to the extreme cold, the sports mat may temporarily detach from the lava foundation. The resulting air bubble allows the lava to move upward more easily, creating uneven surfaces.
Rolling sports surface
By rolling the sports field or tennis court, one brings the loosened lava back to its former position. But this is not a certainty and there may even be permanent unevenness to the lava foundation.
Injuries due to thaw
Uneven surfaces or mats are especially detrimental in tennis. The ball here is small and therefore produces unpredictable behavior. In korfball, the athlete will notice much less of an unevenness, but the damage to the lava foundation is the same.
In addition to changes in athletic characteristics that occur with frost and thaw, one must also consider potential injuries. Too hard ground due to frost or too soft ground when thawing can damage athlete’s knees and ankles.
