Different stance widths are commonly utilized when completing the barbell back squat during athletic general preparedness training. Width manipulation is thought to influence sagittal plane stimuli to the hip and knee extensors, the primary extensor musculature in the squat. However, how width manipulation affects frontal plane stimuli is less understood. Knowledge of hip and knee net joint moments (NJM) could improve exercise selection when aiming to improve sport-specific performance and prevent injuries. Fourteen adult amateur rugby athletes were recruited for this study. After a familiarization period, participants performed wide- (WIDE, 1.5× greater trochanter width) and narrow-stance (NARROW, 1× greater trochanter width) barbell back squats to femur parallel depth, using relative loads of 70% and 85% of one-repetition maximum. Sagittal and frontal plane hip and knee kinetics and kinematics were compared between widths. A Bonferroni-corrected alpha of 0.01 was employed as the threshold for statistical significance. Knee flexion angle was statistically greater in NARROW than WIDE (P < 0.0001, d = 2.56-2.86); no statistical differences were observed for hip flexion angle between conditions (P = 0.049-0.109, d = 0.33-0.38). Hip-to-knee extension NJM ratios and knee adduction NJMs were statistically greater in WIDE than NARROW (P < 0.007, d = 0.51-1.41). At femur parallel, stance width manipulation in the barbell back squat may provide substantial differences in biomechanical stimulus in both the sagittal plane and the frontal plane. In certain contexts, these differences may have clinically relevant longitudinal implications, from both a performance and a injury prevention standpoint, which are discussed.

“…The rationale behind the use of these methods is their efficacy to develop power and strength and the high correlation between these abilities and sprint performance (Alemdaroglu, 2012). For instance, Cronin et al (2007) described that large increases in strength (i.e., maximum strength in squat exercise) are required in order to produce improvements in sprinting speed in recreational athletes.…”

The purpose of this study was to determine the effects of two different strength-power training models on sprint performance. Forty-eight soldiers of the Brazilian brigade of special operations with at least one year of army training experience were divided into a control group (CG: n = 15, age: 20.2 ± 0.7 years, body height: 1.74 ± 0.06 m, and body mass: 66.7 ± 9.8 kg), a traditional training group (TT: n = 18, age: 20.1 ± 0.7 years, body height: 1.71 ± 0.05 m, and body mass: 64.2 ± 4.7 kg), and a complex training group (CT: n = 15, age: 20.3 ± 0.8 years, body height: 1.71 ± 0.07 m; and body mass: 64.0 ± 8.8 kg). Maximum strength (25% and 26%), CMJ height (36% and 39%), mean power (30% and 35%) and mean propulsive power (22% and 28%) in the loaded jump squat exercise, and 20-m sprint speed (16% and 14%) increased significantly (p≤0.05) following the TT and CT, respectively. However, the transfer effect coefficients (TEC) of strength and power performances to 20-m sprint performance following the TT were greater than the CT throughout the 9-week training period. Our data suggest that TT is more effective than CT to improve sprint performance in moderately trained subjects.

“…For example, if while working with a rugby wing, a coach identified that the athlete was below positional norms for relative lower-body strength, relative power, and 10-m sprint speed, then the coach may decide to emphasize the development of strength qualities that are associated with the expression of sprint speed (3,28). Conversely, if an athlete is "strong enough," then it may be beneficial to emphasize sprint-specific work, as additional strength development may not support further changes to speed (12). In this scenario, it would be important to prioritize the common kinematic or technical errors, which if modified, would support improved sprint ability.…”

STRENGTH AND CONDITIONING PROFESSIONALS COMMONLY DEPEND ON EVIDENCE TO GUIDE “WHAT THEY COACH” (E.G., PROGRAMMING), BUT THE SAME CANNOT ALWAYS BE SAID FOR THEIR APPROACH TO “HOW THEY COACH” (E.G., INSTRUCTION). CONSEQUENTLY, PROFESSIONALS HAVE ADOPTED THE CONVENTIONAL VIEW THAT COACHING IS MORE ART THAN SCIENCE, DESPITE THE FACT THAT THERE ARE DECADES OF RESEARCH ELUCIDATING THE SCIENCE UNDERPINNING THIS SO-CALLED ART. IN LIGHT OF THIS GAP, THIS ARTICLE WILL DELVE INTO THIS UNDERPINNING SCIENCE AND PROVIDE AN EVIDENCE-BASED FRAMEWORK FOR INSTRUCTION AND CUEING THROUGH THE LENS OF LINEAR SPEED DEVELOPMENT.
