We appreciate that some terms in swimming can be confusing - here we have a glossary to explain them.  If you feel any are missing please let your coach know and we will update the page.  This is more effective than having them on the session descriptions in TP as we would need to update hundreds of sessions.  

Intensity

We keep intensity simple in swimming.  It can be overly complicated.  

Easy (Ez): Warm-up or active recovery.  This should be a very comfortable intensity.  

Extensive Endurance (Ext End): Describes most intensities below your CSS.  STEADY in the description means an easier aerobic effort; TEMPO is a stronger effort akin to your 60-70min swim pace. 

Critical Swim Speed (CSS) : Threshold swim pace. Derived from a CSS test session, this equates to your 20-30min best effort. 

VO2max (VO2): Describes your ~5-minute best pace.  For convenience, we refer to this as 200, 300 or 400PB time, depending upon how fast CSS is. 

Speed (Sp): Describes a pace above VO2max, roughly 50 -100m best-effort pace. 

Max is self-evident.  The fastest you can go. 

Descend - get faster rep to rep.

Build - pace accelerates within every rep. 

Varied - the pace within a rep varies sharply, unlike build, where it gradually accelerates. 

Other terms

Fc-Bk = Mix free and backstroke. 

SKPS = Skim/kick/pull/swim in equal measure

P&P = pull and paddle

B3 (or another number) = breathe every 3 strokes

PBA = Pull Buoy between Ankles 

CSS +2s (or another number) = 2s per 100m slower than CSS

CSS -2s (or another number) = 2s per 100m faster than CSS

Rolling = within a rep, there will be faster and easier efforts.  The fast will roll through the reps - i.e. 4 x 100 rolling 25 Fast  - in rep 1 the fast is the first 25m, and the rest of the 100 is easier.  In rep 2, the first 25 is easier, then the fast 25, then 50 easier.  And so on.
