    Swim Lactate Testing For Triathletes

    Swim Lactate Testing For Triathletes

    3 Swim Performance Factors

    1. Technique
    2. Physical Conditioning
    3. Psychological Conditioning


    These three are the primary factors that contribute to a swim performance which can be altered with training in the pool & the gym. As discussed in a previous post, technique can prevent injury and maximize power in the water Physical conditioning can be measured using a swim lactate test which directly reflects training variables and paces.

    Lactate testing gives an insight to the strength of the aerobic & anaerobic system providing how long and fast the muscles can contract during an event. It is the only test that can provide an accurate measure of the two energy systems. Lactate is produced by the anaerobic system and used as fuel for the aerobic system which shows why it is important to find a balance between the two systems. For triathletes racing from a sprint to ironman distance, when one system is weak the other system suffers. The lactate test provides an individualized, measurable outcome which can be utilized to inform a coach or athlete how to optimize training variables to balance the energy systems and enhance performance. Swim training variables can be altered by using the pace per 100m provided in the lactate test. Research has shown that successful endurance athletes train 75-80% of their training days at low intensity with a lactate level below 2mmol, 50-65% VO2 max (Seiler and Tonneson, 2009).
