I'm 70 yrs old and started swimming last August. I'm swimming with an awesome Masters team.
I've lost quite a bit of weight, still have 20lbs to go; I'm getting there but have two questions:
1: Am I pulling an extra 20lbs with each pull? At first it seems an obvious yes, but I wonder if being in water makes it different.
2: When the weight is off will it be easier for me to get and stay underwater? - I'm having a tough time pushing off the wall streamline underwater.
odd questions I know, but I'd really appreciate it if anyone can tell me?
Thanks,
Pam
To move forward in the water you must exert enough propulsive force through your pull and kick to overcome the fluid's resistance to movement - that resistance is called drag.
Drag is going to slow you down, but you also need to exert force against the water to actually accelerate you forward and that is directly related to weight (via mass). F= ma. A greater force is required to accelerate a heavier object.
