Maximizing Speed: How Aerobic Endurance Training Enhances Sprint Swimmers' Performance









Hey swimmers and coaches!

I've got an important topic to discuss today that could be a game-changer for sprint events - harnessing the power of aerobic work as most of the thoughts about the 50m races its only Anaerobic work.


I know sprinters and coaches usually focus on anaerobic power. However, research shows the aerobic system contributes 20-25% of the energy during those intense 20-second races like the 50 free (Medbø et al., 1988). This study reveals that during short bursts of intense exercise lasting 15-30 seconds, the aerobic system can make up a substantial 20-30% of the total energy production. Imagine the impact this could have on your sprint performance!


For elite sprinters doing 20-second sprints, the aerobic system still provides around 25% of their energy even when anaerobic metabolism dominates (Bangsbo et al., 1990). That shows the endurance capacity even in short explosive bursts. Elite sprinters were the focus of this research, which highlighted that even during 20-second sprints, where anaerobic metabolism usually dominates, the aerobic system still contributes around 25% of the total energy production. Endurance power in short, explosive efforts - a game-changer indeed!


The different energy systems intricately interact to fuel maximal efforts like sprinting (Gastin, 2001). So, coaches and swimmers, this means aerobic fitness is crucial for sprint dominance!


That extra 20-25% aerobic boost could be the difference between victory and defeat when races are decided by tenths and hundredths of seconds. Make sure sprint workouts incorporate aerobic development too.


The Takeaway:


For our young and enthusiastic swimmers, this means paying attention to your aerobic game is just as crucial as perfecting your strokes. The tiny percentages matter, especially in races decided by mere fractions of a second. Incorporating aerobic work into your training routine can be the secret sauce for conquering that back half of the race with resilience and speed.


Know that your sprint events will be affected If you ignore the aerobic work, and you'll crash in the back half of your race. The research has shown that 20 seconds of all-out effort, like the 50 free swims, the aerobic system contributes to 20% - 25% of the energy for that effort in a race that's always decided by hundreds of a seconds. That 25% is a substantial number."
