Various High Intensity Interval Training (HIIT) protocols have been previously documented to stress the metabolic and cardiorespiratory systems.PURPOSE: The purpose of the study was to compare oxygen consumption (VO2), heart rate (HR), and blood lactate (BLA) between a previously-researched HIIT cycling protocol and a HIIT kettlebell swing protocol. METHODS: 12 moderately active individuals between the ages of 18 to 25-y completed both protocols, separated by at least 48-h, in random order. The kettlebell protocol (KB) consisted of 10 × 60-s intervals of maximal kettlebell swings with an assigned weight interspersed with 60-s passive recovery between intervals. The cycling protocol (C) consisted of 10 × 60-s cycling intervals performed at a workload equivalent to 100% VO2maxinterspersed with 60-s of passive recovery. VO2and HR were continuously recorded during intervals and averaged for analysis. BLA was measured at the end of each interval and averaged for analysis. A dependent groups t-test was used to determine the existence of significant differences between protocols for each dependent variable. RESULTS: Statistical differences were observed between the C and KB protocols for VO2(C: 1.75 ± 0.57 L/min; KB: 1.37 ± 0.68 L/min; p= 0.001) and BLA (C 7.60 ±1.57 mmol/L; KB: 4.60 ±2.05 mmol/L; p= 0.001). No significant difference was observed between protocols for HR (C: 165.6 ±8.4; KB: 156.5 ±15.8; p> 0.05). CONCLUSION: Under these research conditions, the HIIT cycling protocol elicited higher VO2and BLA responses than the HIIT kettlebell protocol. Even though HR was not statistically different between conditions, there was a trend for higher HR responses in the HIIT cycling protocol as well. One explanation for these observations was that the prescribed intensity of the HIIT cycling protocol was simply more aerobically-demanding than the prescribed-intensity of the HIIT KB protocol. Further research should include comparisons of metabolic and cardiorespiratory different responses during different KB protocols or alterations in KB load.
