What is the relationship between stroke rate, DPS, and swim speed?

Speed (m/s) = Stroke Rate (strokes/s) × Distance Per Stroke (m). At 1.7 m/s target pace: if DPS = 2.0 m, required SR = 0.85 strokes/s (51 spm). Shorter, faster strokes trade efficiency for speed in sprint events; longer strokes are more efficient for distance.

How does stroke rate differ between freestyle and backstroke?

Elite 100m freestyle: SR ~50–55 spm. Elite 400m freestyle: SR ~35–42 spm. Backstroke typically runs 5–10 spm lower than freestyle at the same speed. Breaststroke and butterfly have distinct timing cycles making direct rate comparison less meaningful.
