Less drag more speed.
In freestyle, swimmers are trying to stay in the same position throughout, even while executing the breath.

While they don’t have to deal with the challenge of breathing, they do have to manage an effective position on their back, which requires a similar yet distinct skill set.

While undulation is necessary to breathe and recover the arms, swimmers have to ensure they get back in line after each breath and each recovery.
Cont.
Swimmers have to move up & down to breathe and to recover the arms and legs forward.
Because there’s no dolphin kick to help get the hips back up after the breath, swimmers need tofocus on driving back into line to keep drag low.
Rather than constantly reminding them, using a tempo trainer provides them with external feedback as to whether they’re being effective at maintaining a high stroke rate.
