Physiological and Molecular Adaptations to Different Training Modalities in National-level Kayak Athletes
Sponsor: National and Kapodistrian University of Athens
Summary
This interventional study evaluated physiological, molecular, and performance adaptations to different high-intensity training modalities in national-level kayak athletes. Thirty-two athletes were allocated to four parallel groups: high-intensity interval training (HIIT), sprint interval training (SIT), combined training (COMB), or a control condition (CON). The study protocol included a six-week detraining period before baseline (PRE) assessments, followed by a six-week training intervention and a subsequent six-week detraining period. Physiological assessments and blood sampling were performed at PRE and immediately after the training intervention (POST) to evaluate training-related changes. Sprint kayak performance over 500 m was assessed at PRE and POST, with additional assessments conducted 15 and 30 days after completion of the subsequent six-week detraining period. The study aimed to examine the effects of different training modalities on physiological responses, circulating molecular markers, and 500-m kayak performance, as well as changes in performance following detraining.

Conditions
Interventions
High-Intensity Interval Training
Participants performed high-intensity interval training three times per week for six weeks. Each training session consisted of 6 × 30-second intervals at 110% of VO₂max, with 60-second recovery periods between intervals.
Sprint Interval Training
Participants performed sprint interval training three times per week for six weeks. Each training session consisted of 6 × 15-second intervals at approximately 140% of VO₂max, with 150-second recovery periods between intervals.
Combined High-Intensity and Continuous Training
Participants performed combined training for six weeks, with three training sessions per week. The weekly program consisted of one high-intensity interval training session (6 × 30-second intervals at 110% of VO₂max with 60-second recovery periods), one sprint interval training session (6 × 15-second intervals at approximately 140% of VO₂max with 150-second recovery periods), and one 45-minute continuous training session at 80% of VO₂max.
Control
Participants performed three 1-hour walking sessions per week for six weeks and did not participate in the experimental high-intensity training protocols.
