Polarized or Threshold Training on Performance and Fatigue in Elite Swimmers
Aim: This study by Pla et al. aimed to assess the effect of a polarized training intensity distribution on performance and fatigue in 12 male and 10 female junior elite swimmers.
Method: In a cross-over design (2×6-wks) swimmers performed polarized (81% in zone 1, ≤ 2 mmol·L−1 blood lactate, 4% in zone 2 (>2 and <4 mmol·L−1 blood lactate; and 15% in zone 3 > 4 mmol·L−1) or threshold (65%/25%/10%). Before and after both interventions all performed a 100-m maximal swimming test to determine performance, and oxygen consumption and an incremental swimming test. Well-being was assessed with a daily questionnaire.
Conclusion 💡👉 „…In elite junior swimmers, a 6-wk period of polarized training induced small improvements in 100-m time-trial performance and, in combination with less perceived fatigue, forms a viable option for coaches preparing such cohorts of swimmers for competition.“
