Introduction: Aquatic training methods are commonly used to improve cardiovascular fitness and swimming performance in competitive swimmers, yet limited research has compared aquatic high-intensity interval training and aquatic kettlebell training in adolescent swimmers.
Objective: To compare the effects of aquatic high-intensity interval training (AHIIT) and aquatic kettlebell training (AKT) on cardiovascular fitness, swimming performance, and selected hematological parameters in competitive male swimmers.
Methodology: Forty-five competitive male swimmers aged 15–17 years were randomly assigned to three groups: AHIIT (n=15), AKT (n=15), and a control group (n=15). The intervention lasted sixteen weeks with three training sessions per week. Variables measured included VO₂max estimated using the Cooper 12-minute swim test, resting heart rate, swimming speed, 100-m lap time, hemoglobin, and hematocrit. Measurements were taken at pre-test, mid-test, and post-test stages. Post-test scores were analyzed using one-way ANOVA and Scheffé post hoc tests (p≤0.05).
Discussion: Both experimental groups showed significant improvements compared with the control group. AHIIT produced greater improvements in VO₂max, resting heart rate, and swimming performance, whereas AKT showed greater increases in hemoglobin and hematocrit.
Conclusion: Both aquatic training methods improve physiological and performance variables in adolescent swimmers. AHIIT enhances cardiovascular fitness and performance, while AKT promotes stronger hematological adaptations.
