Although the benefits of exercise can never be undervalued, there are risks in any physical activity. Although the game is slower, women are still more anatomically susceptible to cruciate ligament and general knee injuries. Another injury that we've seen multiple instances of, is strained or 'popped' calf muscles - this may be due to the exaggereated 'speed-walking' effect. Goalkeepers are at risk of damaged writs and fingers and of course falls although cushioned, can still cause injury or friction burns on the skin. Some universities are currently collating data as to the nature of walking football injuries and risks asscoiated with the sport.
