I’ve put together a table of training related lingo/acronyms that you may see being used in my blog. These came from various sources found on the internet, but most of them come thanks to my pals over at Beginner Triathlete. I’ve sorted them by discipline/area of interest to try and help make it quicker to find something if you’re unsure of what it means.

Here are some shortcut links to each section:

AHR Average Heart Rate

BPM Beats per Minute (heart rate)
Carbo-loading Eating a high carbohydrate diet (approximately 60-70% of total calories) for the three days leading up to a race to maximally fill the glycogen stores.
CD Cool Down
HR Heart Rate
HRM Heart Rate Monitor
Interval Training Any cardiovascular workout (e.g. biking, running, rowing, etc.) that involves brief bouts at near-maximum exertion interspersed with periods of lower-intensity activity
Lactic Acid Lactic acid is formed from glucose, and used by working muscles for energy. It is thought that muscle cells convert glucose or glycogen to lactic acid, then lactic acid is absorbed and converted to a fuel by mitochondria in muscle cells. Lactic acid is what causes muscle soreness.
Ladder An interval workout with progressively increasing then decreasing distances at each interval. For example, run fast for 400m, jog for 200m, run for 800m, jog for 200m, run for 1200m, jog for 200m, run for 800m, jog for 200m, run for 400m, jog for 200m.
MHR Maximum Heart Rate
Periodization Varying the training levels over discrete periods of time to prevent overtraining
RHR or mRHR Resting Heart Rate or Morning Resting Heart Rate (to distinguish the lowest rate vs. RHR, which could be recovery heart rate.)
