The squat is one of the most widely used exercises in resistance training programs. The aim of this narrative review was to analyze the effect of the squat on lower-limb muscle hypertrophy. Briefly, the available literature indicates that the squat is an effective exercise for inducing hypertrophy of the quadriceps, mainly the vastii, but also the rectus femoris, although to a reduced magnitude. Multiple lines of evidence suggest little to no hamstring hypertrophy from the back squat. Although the gluteus maximus clearly participates mechanically in the back squat, few longitudinal studies exist on the topic. The limited evidence available on this topic suggests deeper squats may be more hypertrophic for the gluteus maximus, and that, squat depth beyond 908 of knee flexion may not provide further hypertrophy of the knee extensors. Despite the popularity of the many squat variations, there are still controversies surrounding their hypertrophic potential for lower-limb musculature. Further studies are needed to investigate the hypertrophic effects of different squat variations, as well as differences in hypertrophy because of squat depth, stance, barbell position, and different squat apparatuses/machines.

Athletes engage in training programs that develop physical and physiological attributes to improve performance over time. However, ensuring athletes are optimally prepared just before competition is also of utmost importance. Indeed, such approaches may often adopt 1 or more strategies in the days, hours, and minutes preceding competition, including exercise priming, active warmup, and/or postactivation performance enhancing (PAPE) activities. Despite a plethora of discrete research, such information seems poorly synthesized, making it difficult for coaches and athletes to implement optimal evidence based physical preparation approaches in many sporting contexts. This article aims to provide a scoping overview of evidence, facilitate discussion, and where possible, propose practical exercise based recommendations that may be useful leading up to (~48 hours–~1 minute) tasks with a short or prolonged endurance component or requiring repeated intermittent efforts (e.g., team based field sports). Well-timed and –designed activities can facilitate several aspects of physical performance, potentially improve athletes’ psychological state(s) and mental preparedness. The benefits of a warm-up are most well documented, but priming and PAPE strategies also warrant consideration. It is intended that the evidence and suggestions presented will be useful for strength and conditioning professionals preparing athletes for competition.

Successful performance in sport is a multifactorial process that includes a blend of technical, tactical, physiological, biomechanical, and psychological features interacting together to result in the desired performance outcome. The strength and conditioning (S&C) program, depending on the sport, can support performance by influencing the physiological and biomechanical components through direct and indirect avenues of impact. Performance planning to achieve identified objectives is typically a long-term process, ranging from a year in seasonal professional team sports to a four-year Olympic cycle. It is critical to develop and implement key strategic processes to ensure that the S&C program effectively supports performance at major competitions. Furthermore, it is essential to have clarity for the role of S&C within the overall sports training program. Having a clear approach to deconstructing and understanding performance from a human performance perspective, showing how and where the impact on performance can be made, and objectively demonstrating the contribution to performance variables is vital. The current article uses the author’s experience of working across a range of Olympic and professional sports to articulate a process for strategic planning and managing S&C support from a technical perspective. Examples from various sports have been used to illustrate critical strategic processes.
