Comparison of Cardiorespiratory and Metabolic Responses Between Kettlebell Half Marathon and Treadmill Running at the Same Average Oxygen Consumption: A Case Study

Abstract

Purposes In kettlebell sport (KS) half marathon, the lift of the kettlebell is required for the highest number of repetitions in 30 min. No data are available on cardiorespiratory and metabolic responses during this exercise routine. The aim of the study was to evaluate cardiopulmonary and metabolic responses to KS half marathon compared to 30 min treadmill running, chosen as a reference paradigm of aerobic exercise, at the same average oxygen consumption (VO2). Methods A male elite KS athlete was enrolled in two trials separated by 7 days of rest. In the first trial, one-hand long-cycle KS exercise with a 1/3 body weight kettlebell was performed for 30 min (kettlebell half marathon, KT); in the second trial, 30 min treadmill running (TR) was performed at the same average VO2 measured in the first trial (speed 9–10 km/h at 1° uphill inclination). Metabolic and cardiopulmonary assessments [respiratory exchange ratio (RER), tidal volume (TV), breathing frequency (f), minute ventilation (VE)], blood lactate (BL) kinetics, heart rate (HR), and blood pressure (BP) were measured in both experimental sessions. Results The average VO2 was 33.3 mL/min/kg in KT and 30.6 mL/min/kg in TR. The subject achieved RERpeak 1.17, RERmean 0.98, HRpeak 172 bpm (94% HRmax), HRmean 86% of HRmax, BPpeak 220/100 mmHg in KT, BLpeak 7.2 mmol/L (during trial) in KT and RERpeak 1.13, RERmean 0.89, HRpeak 142 bpm (78% HRmax), HRmean 70% of HRmax, BPpeak 160/80 mmHg, BLpeak 3.5 mmol/L (4 min after trial) mmol/L in TR. Conclusion Data indicate that a KS half marathon determines much higher cardiopulmonary and metabolic responses to treadmill running performed at similar VO2.

Bioelectrical Impedance Vector Analysis Discriminates Aerobic Power in Futsal Players: The Role of Body Composition

“…The VO 2max mirrors the maximum amount of oxygen an individual can use to support the oxidative production of energy [6]. The most common and reliable method to assess VO 2max is the cardiopulmonary exercise test, recognized a valuable measure not only to assess the functional status and oxygen availability during exercise training but also to discriminate cardiorespiratory, pulmonary and musculoskeletal function at the same average oxygen consumption [7]. For the first time, Alvarez et al [8] showed that high values of VO 2max were essential for futsal athletes at the professional level, suggesting the relevance of aerobic power in futsal [8].…”

Features of Respiratory Cycles Formation in «long Cycle» Exercise of Kettlebell Lifting Sports

“…В настоящее время в области гиревого спорта ученых интересуют количественные показатели потребления кислорода (V O2 ) и частоты сердечных сокращений (ЧСС) при интенсивных упражнениях с гирями в сравнении с такими же показателями в других видах спорта [3]. Например, обнаружено, что упражнения с гирями вызывают гораздо более высокую сердечно-легочную и метаболическую реакцию, чем бег на беговой дорожке, выполняемый с аналогичным уровнем V O2 [4]. Небольшое количество работ посвящено определению способов дыхания в упражнениях с гирями по видеоматериалам, где количество дыхательных циклов определяется по характерным для дыхания движениям груди, живота и лопаток [5].…”
