2-D VS 3-D Analysis
Mechanical work and predicted energy expenditure was also quantified. A secondary purpose was to compare kinematic and kinetic calculations between 2-D and 3-D analyses for both sumo and conventional deadlifts. Two 60-Hz video cameras recorded 12 sumo and 12 conventional style lifters during a national powerlifting championship. Parameters were quantified at barbell liftoff (LO), at the instant the barbell passed the knees (KP), and at lift completion. Unpaired t-tests (P ,0.05) were used to compare all parameters. Twenty-four male powerlifters served as subjects. Twelve of the subjects performed the conventional deadlift, whereas the remaining 12 subjects performed the sumo deadlift. All subjects wore a one-piece lifting suit. Mean age, body mass, and body height were 47 yr, 71.6 kg, and 172 cm, respectively, for the sumo group, and 46 yr, 76.8 kg, …show more content…
The biomechanical differences between sumo and conventional deadlifts result from technique variations between these exercises. Understanding these differences will aid the strength coach or rehab specialist in determining which deadlift style an athlete or patient should employ (Ez). (Hales) Knowing the benefits of each lift will help you to understand the benefits of doing both and knowing which style will help you lift the most. Although each lift activates different muscles significantly, there are a lot of similarities is muscle activation. Both styles use the lumbar and T-spine, the posterior chain and upper back muscles to some degree. Also, alternating styles can be good for the lifter because it will engage other muscles, only making the lifter stronger. In conclusion, the lift styles differ significantly in technique and effects, but it is best for the lifter to practice both to see which style works best for their particular body type and
