Who is Jamie Sadlowski? Jamie Sadlowski is now very well-known to followers of long-drive competition events, and he is the current reigning world champion . When one first sees Jamie Sadlowski, it is hard to believe that he is the world long-drive champion.
He is 5'11" in height and he only weighs lbs. In terms of body physique, he seems puny in comparison to many other first-class long-drive competitors eg. One therefore wonders how he can drive the ball further than his fellow competitors.
However, when one sees his swing for the first time, one is immediately dazzled by the speed of his swing. From a swing power perspective, the first question one needs to answer regarding Jamie Sadlowski's swing is whether he is a swinger or a hitter.
Jamie Sadlowski is definitely a left-arm swinger and he uses a pivot-drive action to activate and release the master power accumulator PA 4.
In a left arm swinger's action, the standard swing action involves the use of three power accumulators in a set sequence 4: However, Jamie Sadlowski only uses two power accumulators in a standard release sequence of 4: Jamie Sadlowski does not use PA 3 called the transfer power accumulator because he does not use any hand-roll over action in his backswing or downswing, and he also does not use PA 1 active right arm straightening action that drive-loads the clubshaft.
Jamie Sadlowski has a particular swing idiosyncrasy that has a major effect on his swing biomechanics, and that is his tendency to have i a strong left hand grip 4 knuckle grip and his associated anatomical tendency to have ii an internally rotated left arm at address.
Those anatomical choices means that he doesn't use any left forearm pronatory swivel movement in the takeaway takeaway swivel action and he therefore doesn't use a left forearm supinatory swivel movement release swivel action during the late downswing.
The fact that his left arm is internally rotated at address, and therefore at impact, is responsible for the fact that he "chicken-wings" his left arm in the late downswing, at impact, and in the followthrough. It also is responsible for the fact that he doesn't use a horizontal hinging action in the followthrough.
Jamie Sadlowski has a standard address posture that is characteristic of a traditional left arm swinger.
Jamie Sadlowski at address - capture image from his swing video  At address, Jamie Sadlowski has a small degree of rightwards spinal tilt see yellow line. That causes his head to be behind the center of his stance and well behind the ball.
His legs are wide apart - slightly wider than shoulder width and his feet are splayed open about 10 degrees. His pelvis and knees and shoulders are square to the ball-target line.
He holds his hands centrally, and his clubshaft and left arm are therefore not in a straight line relationship at address. Most importantly, note that the back of his left hand is facing skywards facing the ball-target line at address - due to a very strong left hand grip 4 knuckle grip.
Also most importantly, note that his left upper arm is internally rotated in the left shoulder socket joint and that anatomical phenomenon causes the dorsum back of his left forearm to face the ball-target line rather than the target at address, and it also causes his left elbow's antecubital fossa hollow in front of the left elbow joint to face away from the target rather than face the ball-target line.
This anatomical fact will have a significant affect when his left arm gets back to that same position at impact - and it is causally related to the fact that he "chicken-wings" his left arm at impact. Jamie Sadlowski uses a standard one-piece takeaway at the start of his backswing action.
Jamie Sadlowski's backswing sequence - capture images from his swing video  Images 2 and 3 show that Jamie Sadlowski uses the standard one-piece takeaway, where he tries to keep the right arm relatively straight during the takeaway - note that the right elbow has only a small degree of bend at the end of the takeaway image 3.
That arm movement, where the right arm moves away from the right side of the torso, creates a "feeling" of creating width in the backswing. His left arm is already internally rotated at address, and he simply pulls his internally rotated left arm back away from the target during the takeaway.
During his one-piece takeaway, he allows his shoulders to naturally turn perpendicularly around his rightwards tilted spine, and that causes his shoulder turn to be relatively horizontal left shoulder is only slightly lower than the right shoulder.UOAs are a great tool in the Management of any machinery that uses liquid lubricants.
Unfortunately, their real value is often misunderstood by those who contribute to BITOG. Analytical centrifugation (AC) is a powerful technique for the measurement of particle size distributions. This study evaluates its performance for the grouping of particulate materials according to the European Commission's recommendation on the definition of a nanomaterial, which bases on the number-weighted median diameter.

A rocket has variable mass because its mass decreases over time, as a result of its fuel (propellant) burning off.
