Physioworks Exercise Physiology – Are you benefiting from Squats?



the fundamentals of squattingThe squat exercise is a full body exercise that is compound and trains predominantly the muscles of the thighs, hips and buttocks.

This paper will discuss research behind squat techniques, the reason for it and prescription for best athletes. The video at the end then demonstrates correct squatting technique.

Squat’s are great way to develop more muscle mass. Research has shown squats create more growth hormone (GH) compared to leg press. GH is an important aspect of muscle mass.

Research from North Texas University suggests that strength training using bars and dumbbells produces better results as training free weights incorporates more muscle stimulation and physical coordination which is important for muscle mass.

  • This research tested ten (10) 25 year old males with experience with strength training.
  • They each did two sessions a week, the first session doing squats & the other session doing leg press.
  • Both sessions were “Heavy Sessions” at 80% 1RM.
  • Immediately after each session, then after 15 minutes and 30 minutes the researchers found that the rate of GH is higher in squats compared to leg press.
  • The reason behind this could be because the men had to work against their body weight, as well as work at a greater range of movement compared to a leg press.

There are different ways to perform a squat and recent research from Appalachain State University suggests there really isn’t much of a difference within box squats and an ordinary squat.

  • Their results suggest that at 70% to 80% 1RM there was no statistical difference in strength for the two types of squats.
  • They concluded: “The removal of the stretch-shortening cycle by using the box squats may be beneficial as a training tool for those athletes performing concentric-only actions in their sport. For most sport applications, a squat including a stretch shortening cycle may be of greater benefit”.
  • Box squats is a great exercise for athletes who want to get faster. A periodised program is an important aspect to see optimal results.

All footballers want to move faster and the answer is to squat, and squat ‘Heavy’.

  • Research has also shown that heavier squat’s results in faster sprints. A commitment to the gym and focusing on heavy squats has likelihood to translate and increase on field sprinting ability.

Conclusion: Next time you go to the gym, make sure you have a goal. Remember that the research behind squats is not only beneficial for training adaptations but also for rehabilitation, as it’s a functional exercise when performed correctly.
