Functional movements are designed to look at how our body functions in different environments. Power is often performed in the vertical plane and very stable positions of the body. Both life and sport require a great deal more complexity of movement with direction and deceleration playing key roles. The Kettlebell Lunge Clean (KLC) exercise is a safe and powerful exercise to teach these qualities and progress the power development and force absorption capabilities of the individual.

Lawrence, MA, Ostrowski, SJ, Leib, DJ, and Carlson, LA. Effect of unstable loads on stabilizing muscles and bar motion during the bench press. J Strength Cond Res XX(X): 000-000, 2018-Unstable loads are anecdotally used to increase muscle stabilizer strength and utilization; however, there is little evidence to support these claims. Twelve male powerlifters (age 28.6 ± 5.2 years, body mass 105.6 ± 14.5 kg, lifting experience 9.8 ± 6.0 years, and bench press 5 repetition maximum [5RM] 133.6 ± 30.9 kg) pressed their 5RM in one stable condition with a standard barbell, and 3 unstable conditions using a flexible barbell with weights suspended from elastic bands...

Kettlebells often replace dumbbells during common resistance training exercises such as the overhead press. When performing an overhead press, the center of mass of a dumbbell is in line with the glenohumeral joint. In comparison, the center of mass of the kettlebell is posterior to the glenohumeral joint. Posterior displacement of the kettlebell center of mass may result in less stability during the pressing motion. The purpose of this study was to examine muscle activity during an overhead press with resistance training implements of differing stability...

The purpose of this study was to examine differences in the Electromyography (EMG) amplitude of the serratus anterior between 45° kettlebell carries and 90° kettlebell carries. Thirty-three men aged roughly between 19 and 23 and who were either college or professional baseball pitchers were chosen and randomly assigned to either perform the 45° kettlebell carry followed by the 90° kettlebell carry ( n = 17) or the 90° kettlebell carry followed by the 45° kettlebell carry ( n = 16). Each pitcher was instructed in the proper usage of the exercise and assigned a short break between the two carries...

J Strength Cond Res XX(X): 000-000, 2018-Kettlebell lifting has become popular both as a strength and conditioning training tool and as a sport in and of itself: Girevoy Sport (GS). Although several kettlebell multimovement protocols have been analyzed, little research has attempted to quantify the aerobic stimulus of the individual events in GS, which could better inform kettlebell-related exercise prescription...

This review covers underlying physiological characteristics and training considerations that may affect muscular strength including improving maximal force expression and time-limited force expression. Strength is underpinned by a combination of morphological and neural factors including muscle cross-sectional area and architecture, musculotendinous stiffness, motor unit recruitment, rate coding, motor unit synchronization, and neuromuscular inhibition. Although single- and multi-targeted block periodization models may produce the greatest strength-power benefits, concepts within each model must be considered within the limitations of the sport, athletes, and schedules...

Kettlebell (KB) training has become an extremely popular exercise program for improving both muscle strength and aerobic fitness. However, the cardiac autonomic modulation and blood pressure (BP) responses induced by an acute KB exercise session are currently unknown. Understanding the impact of this exercise modality on the post-exercise autonomic modulation and BP would facilitate appropriate exercise prescription in susceptible populations. The present study evaluated the effects of an acute session of KB exercise on heart rate variability (HRV) and BP responses in healthy individuals...

Kettlebell exercises have become an increasingly popular form of resistance training and component of lower body rehabilitative training programs; despite a lack of scientific literature illustrating internal mechanisms and effectiveness of these approaches. Participants (n=14) performed three different styles of kettlebell swings (hip hinge, squat and double knee extension) and were assessed for medial hamstrings (MH) and biceps femoris (BF) myoelectrical activity via surface electromyography (sEMG). Bipolar pre-gelled Ag/AgCl surface electromyography (sEMG) electrodes (10mm diameter, 20mm inter-electrode distance) were placed on the participant's dominant limb after correct skin preparation...

BACKGROUND: Kettlebell (KB) and indian club swings (ICS) are used diversely for developing strength and power. It has been proposed that multiple swing techniques can be used interchangeably to elicit similar adaptations within performance training. Hypothesis/Purpose: It was hypothesized that there will be not be a difference in peak joint angles between types of swings. Furthermore, given the nature of the overhead kettlebell swing (OKS), it was hypothesized that the OKS will be associated with a greater cycle time and a greater vertical impulse compared to shoulder height swing (SKS) and ICS...

BACKGROUND: Kettlebell lifting has gained increased popularity as both a form of resistance training and as a sport, despite the paucity of literature validating its use as a training tool. Kettlebell sport requires participants to complete the kettlebell snatch continuously over prolonged periods of time. Kettlebell sport and weightlifting involve similar exercises, however, their traditional uses suggest they are better suited to training different fitness qualities. This study examined the three-dimensional ground reaction force (GRF) and force applied to the kettlebell over a 6 min kettlebell snatch set in 12 kettlebell-trained males...
