Re: Batspeed Training Aid

Posted by: pastime00 (rolltr@yahoo.com) on Mon Jul 5 23:02:28 2010

Question...My son had some bat drag issues end of last season and start of this spring season. I really worked on him hitting out front with barrel and paid little attention to rotational hitting. I just wanted him to use his hands more and get barrel out front. Well that was great and was on fire for tourney in Feb and first couple weeks in March spring season, but then slump. Bat drag induced. Got him out of that then he toyed with other things and had slump..power outage.

Recently I've worked on him for power and told him to reach connection. Really shove that elbow to connection.

NOW, if you look at his swing, it looks like all he's done is get to the bat lag position and driven the knob to the ball FOREVER. Hands end up in front of ball, ball over plate, bat pointing backwards about, yes, 30 degrees.



It's either:
1) too much linear cues
2) He's just worn out
3) It's me telling him to shove that elbow to 'connection' and him unable to get that barrel whip transfered.

I wouldn't know how to fix any of it but #2. Anyone got any ideas? Every swing was like that. Hands way out, ball, barrel lagging behind and angled back. With no power and no leverage everything pounded into ground, weak, and 2nd baseman side. Easy outs.

> I am starting this month's discussions by outlining the bio-mechanical principles that are reinforced with a new rotational training aid we will soon offer on the site. Over the past few months, other coaches and myself have tested the aid on our students. We find it does a great job in helping the student overcome many of the problems they have in acquiring sound rotational mechanics.
> One of the main problems we find in our students is they rely to much on the back-side (Back-Hand Dominate) and make inefficient use of the lead-side. Video analysis of these hitters shows that relying too much on the back-side causes the trajectory of their back-elbow to accelerate much faster than the lead-elbow. This results in their back-elbow trajectory swinging under their armpit and in many cases catching up to the advancement of the lead-elbow (back-elbow under the lead-elbow).
> Video analysis of high-level mechanics shows that their lead-elbow accelerates at the same rate as their back-elbow. This means that the distance between their elbows remains relatively constant from initiation to contact. This also means their forearms are accelerating at the same rate (however, in opposing directions).
> Below is one of our video clips that discuss the trajectory of the back-elbow of four good hitters. Note, (1) that the distance between their elbows remains fairly constant and (2) approaching contact, their elbows and forearms are applying force from 'opposing' directions -- back-side driving the back-forearm forward as the lead-side pulls the lead- forearm rearward. This result is applying torque (BHT) that really accelerates the meat of the bat to contact.

> Back-side dominate mechanics that cause the back-elbow to accelerate much faster than the lead-elbow results in both forearms moving forward at contact. Both hands applying a forward force induces little torque which results in the bat-head dragging 30+ degrees behind the hands in the contact zone. -- This is what our new training aid is designed to correct. It promotes balanced mechanics where both elbows and forearm accelerate at the same (although opposing) rate.
