I'd like to ask to ask a personal question. What is your height and weight? Also, do you think that players need to maintain a certain weight in order to have the optimum power/weight ratio?
Weight/Height I´m about 184 cm high and I weigh around 75-77 kilos!! I think 74 kilos is about the right for singles players and doubles players can weigh some more because in doubles hard smashes are required. Kind Regards Jonas
Jonas, check out this thread on BMI. Jonas, based on your date, you have a BMI of 22, very decent for a badminton player. You are suited for both singles and doubles play.. http://www.badmintonforum.com/vb/showthread.php?s=&threadid=5591&highlight=bmi
