Differences in time spent in the anaerobic zone between incremental treadmill test and incremental kettlebell swinging test

Diagnostic procedures comprise numerous methods to evaluate aerobic and the anaerobic capacity. Many studies have been conducted with the aim of establishing an adequate protocol for evaluating functional capacities (Myers et al., 2000). Some studies show that kettlebell may have impact on cardiorespiratory system (Farrar et al., 2010, Fallatic et al. 2015). Stimulate the already mentioned and similar works Šentija et al. (2017) constructed new protocol for evaluating functional capacity. The main goal of this study was to determine does this newly designed protocol, incremental kettlebell swinging test – IKT, can use for determination of anaerobic capacity. The study group consisted of 2 females and 8 male healthy subjects (age=24, 27±2, 17 ; height=181, 32±9, 29 ; weight=78, 73±12, 73). Measurements were carried out at the Faculty of Kinesiology, University of Zagreb. The duration of anaerobic zone was measured in Incremental treadmill test (tAn-ITT (s)) and incremental kettlebell swinging test (tAn-ITT (s)). For statistical analysis we used Correlation (p<0, 05) in software package Statistica for Windows 12.0. We found there are mild negative correlation between variables tAn-ITT and tAn-IKT (r=- 0, 42 p>0, 05). Considering achieved values average spent time in anaerobic zone in ITT was 255, 00±32, 40 sec and in IKT was 129, 00±54, 86 sec. This differences in time spent in the anaerobic zone between ITT and IKT protocol most likely emerged because in ITT protocol cardio-respiratory endurance play a dominant role while in IKT protocol power endurance comes to the fore. The male subject that have more muscle mass had better results in IKT, while females and male subject with less muscle mass had worse results. These results show us that power endurance has an impact on anaerobic capacity in activities that include external load. For more accurate conclusion it is necessary to do further research’s with incremental kettlebell swinging test.
