Nimeke Effects of Kettlebell Training on Aerobic Capacity. Tekijä Falatic, J Asher Muut tekijät Plato, Peggy A Muut tekijät Holder, Christopher Muut tekijät Finch, Daryl Muut tekijät Han, Kyungmo Muut tekijät Cisar, Craig J Viite J Strength Cond Res Viite Volume: 29, Issue: 7, Date: 2015 Jul , Pages: 1943-7
Vuosi 2015 Tiivistelmä This study examined the effects of a kettlebell training program on aerobic capacity. Seventeen female National Collegiate Athletic Association Division I collegiate soccer players (age: 19.7 ± 1.0 years, height: 166.1 ± 6.4 cm, weight: 64.2 ± 8.2 kg) completed a graded exercise test to determine maximal oxygen consumption (V̇O2max). Participants were assigned to a kettlebell intervention group (KB) (n = 9) or a circuit weight-training (CWT) control group (n=8). Participants in the KB group completed a kettlebell snatch test to determine individual snatch repetitions. Both groups trained 3 days a week for 4 weeks in addition to their off-season strength and conditioning program. The KB group performed the 15:15 MVO2 protocol (20 minutes of kettlebell snatching with 15 seconds of work and rest intervals). The CWT group performed multiple free-weight and dynamic body-weight exercises as part of a continuous circuit program for 20 minutes. The 15:15 MVO2 protocol significantly increased V̇O2max in the KB group. The average increase was 2.3 ml·kg⁻¹·min⁻¹, or approximately a 6% gain. There was no significant change in V̇O2max in the CWT control group. Thus, the 4-week 15:15 MVO2 kettlebell protocol, using high-intensity kettlebell snatches, significantly improved aerobic capacity in female intercollegiate soccer players and could be used as an alternative mode to maintain or improve cardiovascular conditioning.
Nimeke Snatch trajectory of elite level girevoy (kettlebell) sport athletes and its implications to strength and conditioning coaching. Tekijä Ross, James A. Muut tekijät Wilson, Cameron J. Muut tekijät Keogh, Justin W. L. Muut tekijät Ho, Kuok Wai Muut tekijät Lorenzen, Christian Viite International Journal of Sports Science & Coaching vol. 10, no. 2-3 (2015), p. 439-452 Vuosi 2015 Tiivistelmä Girevoy sport (GS) has developed only recently in the West, resulting in a paucity of English scientific literature available. The aim was to document kettlebell trajectory of GS athletes performing the kettlebell snatch. Four elite GS athletes (age = 29-47 years, body mass = 68.3-108.1 kg, height 1.72-1.89 m) completed one set of 16 repetitions with a 32.1 kg kettlebell. Trajectory was captured with the VICON motion analysis system (250 Hz) and analysed with VICON Nexus (1.7.1). The kettlebell followed a ‘C’ shape trajectory in the sagittal plane. Mean peak velocity in the upwards phase was 4.03 ± 0.20 m s-1, compared to 3.70 ± 0.30 m s-1 during the downwards phase, and mean radial error across the sagittal and frontal planes was 0.022 ± 0.006 m Low error in the movement suggests consistent trajectory is important to reduce extraneous movement and improve efficiency. While the kettlebell snatch and swing both require large anterior-posterior motion, the snatch requires the kettlebell to be held stationary overhead. Therefore, a different coaching application is required to that of a barbell snatch. (PsycINFO Database Record (c) 2015 APA, all rights reserved)(journal abstract)
Nimeke Comparison of cardiorespiratory and metabolic responses in kettlebell high-intensity interval training versus sprint interval cycling. Tekijä Williams, Brian M Muut tekijät Kraemer, Robert R Viite J Strength Cond Res Viite Date: 2015 Sep 8, Tiivistelmä The purpose of this study was to compare the effectiveness of a novel exercise protocol we developed for kettlebell high-intensity interval training (KB-HIIT) by comparing the cardiorespiratory and metabolic responses to a standard sprint interval cycling (SIC) exercise protocol. Eight men volunteered for the study and completed two preliminary sessions, followed by two 12-minute sessions of KB-HIIT and SIC in a counterbalanced fashion. In the KB-HITT session, three circuits of four exercises were performed using a Tabata regimen. In the SIC session, three 30-second sprints were performed, with 4-minutes of recovery in between the first two sprints and 2.5-minutes of recovery after the last sprint. A within-subjects design over multiple time points was used to compare oxygen consumption (VO2), respiratory exchange ratio (RER), tidal volume (TV), breathing frequency (f), minute ventilation (VE), caloric expenditure rate (kcalmin), and heart rate (HR) between the exercise protocols. Additionally, total caloric expenditure was compared. A significant group effect, time effect, and group x time interaction were found for VO2, RER, and TV, with VO2 being higher and TV and RER being lower in the KB-HIIT compared to the SIC. Only a significant time effect and group x time interaction were found for f, VE, kcalmin, and HR. Additionally, total caloric expenditure was found to be significantly higher during the KB-HIIT. Tiivistelmä The results of the present study suggest that KB-HIIT may be more attractive and sustainable than SIC, and can be effective in stimulating cardiorespiratory and metabolic responses that could improve health and aerobic performance.
Nimeke Elevation of cardiac troponins measured after recreational resistance training. Tekijä Savukoski, Tanja Muut tekijät Mehtälä, Laura Muut tekijät Lindahl, Bertil Muut tekijät Venge, Per Muut tekijät Pettersson, Kim Viite Clin Biochem Viite Volume: 48, Issue: 12, Date: 2015 Aug , Pages: 803-6 Vuosi 2015 Tiivistelmä: Whereas elevated cardiac troponin (cTn) concentrations i.e. above the 99th percentile of healthy reference population (recommended cutoff for the diagnosis of myocardial infarction) are well-documented in healthy individuals after prolonged and/or intensive exercises such as marathons, data on less-strenuous sports are scarce. Therefore, our aim was to investigate cTnI and cTnT release in response to recreational resistance training, here a single-bout of 1-h kettlebell workout.
