Cardiorespiratory Responses to Kettlebell™ Training Exercise
1162 Board #17 2:00 PM – 3:30 PM
Although resistance training using Kettlebells™ is not new, the popularity of Russian Kettlebell™ training has recently grown in the U.S. due to promotion by Pavel Tsatsouline. However, at the present time there appears to be little scientific literature on Kettlebell™ exercise.
Therefore, the purpose of this study was to describe the cardiorespiratory responses to a typical 30-minute bout of Kettlebell™ training.
Five males and five females (24–58 yrs) were recruited to participate in the study. Each performed five sets of ten repetitions for three Kettlebell™ exercises each separated by 1 minute of rest. The exercises consisted two-arm swings, one-arm snatches (half performed with each arm), and one-arm clean and presses (using right and left arms). The females used a 4 or 8 kg Kettlebell™ based on strength and the males used an 8, 12, or 16 kg Kettlebell™. The cardiorespiratory responses to the exercise were measured using a Parvo Medics TrueMax™ 2400 metabolic system. The data were analyzed using simple descriptive statistics.
The cardiorespiratory responses varied greatly among the subjects and were related to the size Kettlebell™ each used. After the intial adjustment to exercise, ventilation (BTPS) ranged from about 24–39 L/min. This corresponded to tidal volumes and respiratory rates from 0.9–1.4 L/br and 24–41 br/min. Oxygen consumption values were from 0.65–1.28 L/min or 9.7- 18.0 ml/kg/min. Respiratory exchange ratios were from 0.88–1.07 with values typically below 1.0. Exercise heart rates were found to be between 101–143 bts/min and mean (±SEM) blood lactates following exercise were 4.3±1.8 mmol/L.
The cardiorespiratory responses to Kettlebell™ exercise were relatively low. The values were less than reported for traditional weight training exercise performed at 40% of one-repetition maximum. The low response found for Kettlebell™ exercise was probably due to the incorporation of momentum in Kettlebell™ training along with the size of Kettlebell™ used by the subjects.
