The Biceps and Brachialis are strong decelerators of the... elbow extension component of throwing which is why it is a common location for day 1 soreness ❤️Give yourself some soft tissue love with these Biceps Tack and Pump techniques + The Throwing Arm Myofascial Stretch 🔑Pin down the Biceps in a shortened position (bent elbow) and lengthen/glide it by maintaining pressure and extending the elbow. Work up and down the belly of the muscle 🔥 You can make this a little more specific to the biceps by adding in pronation with will elongate the biceps even further If the biceps shortens over time, there are two common outcomes: ⚾️ Loss of Elbow Extension Range of Motion ⚾️ Forward tipping of the throwing shoulder Neither are Ideal ** This needs to be done combined with a holistic approach of an S&C program and proper workload management as some common causes of this can be poor workload dosing or simply lack of strengthshow more

One of the best ways to hit the ball... straighter is by focusing on the extension of your right arm through the strike. When the trail arm straightens, it delivers the club squarely and helps your body release its stored energy in the right direction. Too many golfers collapse the right arm early or “chicken wing” the left, which causes pulls, slices, and inconsistency. Instead, think of the right arm extending down the target line after impact—just like Hogan, Snead, and so many classic swingers did. That extension keeps the clubface square, compresses the ball, and sends it flying on a rope. Work on this move and you’ll be amazed how much straighter your shots become.show more

Scientific research revealed that almost all bowling actions contained... some degree of straightening at the elbow (referred to in these Illegal Bowling Regulations as “Elbow Extension”). In theory, therefore, the vast majority of bowlers, with actions considered by umpires to be legal under the Laws of Cricket, were contravening Law 24(3) each time they delivered the ball. It was also demonstrated in studies by human movement specialists that such Elbow Extension in a bowling action became noticeable to the naked eye – and started to look like a throw – when it exceeded 15 degrees. In order to ensure that the intention behind Law 24(2) was upheld and that the distinction between bowling and throwing the ball remained, the ICC has introduced regulations stipulating a maximum degree of permitted Elbow Extension in a bowling action. As with other regulations and Playing Conditions issued by the ICC, these Illegal Bowling Regulations modify the Laws of Cricket as applied to cricket played under the ICC’s jurisdiction. An Illegal Bowling Action is defined in these Illegal Bowling Regulations as a bowling action where a bowler’s Elbow Extension exceeds 15 degrees, measured from the point at which the bowling arm reaches the horizontal until the point at which the ball is released (any Elbow Hyperextension shall be discounted for the purposes of determining an Illegal Bowling Action). According to the Suspect Bowling Action procedure, delivering the ball without elbow extension is acceptable. Key Factors Elbow Flexion Angle (Degrees) - Upper arm horizontal ( Max - Min ) - Ball Release - Elbow Extension Note :- 4.1.2 in the event of a Player being reported during a Match in a Major ICC Event, the Independent Assessment shall be carried out on an expedited basis. Accordingly, unless exceptional circumstances exist, the Independent Assessment shall be carried out within a period of 72 hours from the time of the ICC’s receipt of the Match Officials’ Report;show more

⚾️ It is no secret that elbow injuries, specifically... UCL injuries, have been on a rise in recent years ➡️ The reason for this is so multi-factorial that it is impossible to pinpoint any 1 reason for an injury 💪 With the constant improvement in the development of pitchers, both skill side and S&C, we are seeing an increase in velocity across all levels of baseball 🎟This is obviously a Great thing for Punching Tickets but also leads to more forces being passed through the medial elbow 🔥There are really 3 proactive actions we actions we can take to counteract this: 1) Address pitching mechanics if there are deficiencies 2) Appropriately manage chronic/acute AND Total workloads 3) Increase the capacity and stress the elbow can handle 🔥 We will specifically dive in to the 3rd component of this in this thread. In short, the answer is simple, GET STRONG FOREARMS 3 WAYS VALGUS FORCE IS DISPERSED ✅ Radiocapitellar Joint Compression When a valgus stress is applied to the elbow, it is attempting to open up or gap the medial (inside) portion of the elbow. This is also the Orthopedic Test for a UCL injury. While this force is trying to gap the medial portion of the elbow, it is also compressing the lateral side. When the radius and lateral humerus compress, this acts as a stopping point for the elbow going into that valgus motion ✅ Forearm Musculature In addition to the UCL on the medial side of the elbow, there is also a group of forearm muscles that span that area and attach to the same portion of the elbow, the medial epicondyle. These muscles include: Pronator Teres, Flexor Carpi Ulnaris, Flexor Carpi Radialis, Flexor Digitorum Superfiscialis, and the Palmaris Longus. With that specific attachment to the medial epicondyle and their respective distal attachments, these do a great job of accepting the valgus force and protecting the UCL. There is some research that states FCU does the best job of the muscles listed, but we believe the best action is to strengthen all of them. The best ways to attack this is with movements including: finger flexion, wrist flexion, Ulnar deviation (moving pinky towards medial elbow), and Pronation of the forearm ✅ Ulnar Collateral Ligament (UCL) What doesn’t get absorbed by the first two structures is placed on the UCL. Previous research has shown that a UCL with no other structures involved is able to withstand ~35 nm of force before failure The Problem is: Every Pitch produces far more than 35nm of Valgus Stress. This shows us just how important the other 2 mechanisms are! * Exercises in the videos should be a complement to your entire S&C Program and is not designed to replace itshow more
