Swimming can feel like it has its own language when you're on the pool deck. There’s a lot of terminology, from training phrases to swimming slang, that can be unfamiliar to both first-time and experienced swimmers. This article will explore the training terminology you might hear on the pool deck and see in the DuoSwim app.

Training Terms

  • IM (Individual Medley): Complete the set by swimming one repetition of each stroke: Butterfly (Fly), Backstroke (Back), Breaststroke (Breast), and Freestyle (Free).

  • Build: Each swim starts slow and ends fast.

  • Descend: Swim faster over the duration of a set.

  • Ascend: Swim slower over the duration of a set.

  • Neg Split (Negative Split): Swim faster on the second half of an individual repetition.

  • DPS (Distance Per Stroke): Swim slowly while maximizing your distance per stroke.

  • Best Average: Swim as fast as possible, maintaining the same speed on every repetition within a set.

  • Best Effort: Swim as fast as possible on every repetition within a set.

  • Race Pace: Swim at your goal race pace on every repetition within a set.

  • @ (Interval): Swim time plus rest time for each repetition.

  • Stroke Count: The number of strokes you take in one length of the pool.

Training Zones

  • Aerobic Training: Swimming moderately over a long period of time.

  • Anaerobic Training: High-intensity swimming that produces lactic acid.

  • Aerobic Threshold: Training at 70% of your maximum heart rate (MHR).

  • Anaerobic Threshold: Training at the intensity just below the point where lactic acid begins to accumulate.

  • Sprint Training: Swimming a short distance at the highest possible speed.

  • Taper: Reducing the volume and intensity of training before a major competition to allow the body to rest and recover.

  • VO2 Max: Training at an intensity that maximizes your body's oxygen consumption.

  • Threshold Training: Training at or near your lactate threshold to improve endurance.

  • Recovery: Low-intensity swimming meant to promote muscle recovery and reduce fatigue.
