  • Summary of pitching mechanics replies

    On December 9th I posted the following request:

    I have been asked to comment on biomechanical factors affecting (baseball
    or softball) pitching performance, with specific interest in comparisons
    between underhand and overhand deliveries and between men and women. I have
    a pretty meager bibliography to start with and would greatly appreciate
    comments or suggestions about relevant research. For instance, how do
    release velocities differ? How are body size, strength, flexibility related
    to performance? I'll post a summary of responses. Thanks.

    Since several individuals asked for a summary of the replies I received,
    they follow (slightly edited):

    Mike Feltner has done and published research on baseball throwing. I know
    Mike from his days at Indiana University. His current email is
    mfeltner@pepvax.pepperdine.edu. I haven't seen any postings from him on the
    Biomch group, so not sure he reads it.

    Another student at IU a number of years ago, now at Penn State, Sherry
    Werner, did some research on softball pitching. Not sure if it was ever
    published. Her email is sxw13@psuvm.psu.edu. She has to pay for her access
    to internet so keep it short.

    Larry- I did not study the differences between over and underhand or
    between men and women.... but I did take a crack at the antropometry for
    maximum distance throws and I thought about the effects of object size and
    weight... my focus was on a perceptual question. See Bingham, G.P.,
    Schmidt, R.C. & Rosenblum, L.D. (1989) Hefting for a maximum distance
    throw: A smart perceptual mechanism. Journal of Experimental Psychology:
    Human Perception and Performance, 15(3), 507-528

    I think you are probably aware of this paper, but just in case ...

    In regards to your request for softball pitching literature, I have a copy
    of a Master's thesis from Indiana U. which quantified certain aspects of
    women's windmill pitching. The reference is provided below.

    Werner, S.L. (1987). Selected kinematic and kinetic parameters of the
    windmill softball pitch. Unpublished Master's thesis, Indiana University.

    Hope it helps. Also, in our lab we have been studying gender differences in
    throwing mechanics among children. If you are interested in this, let me
    know, and I'll send you what we have.

    I would suggest, as a beginning point, seeing Hay's (1993) text "The
    Biomechanics of Sports Techniques" (4th ed.). Pitching motions and various
    biomechanical factors are addressed for both softball and baseball in this
    text.


    Also recommending Jim Hay's book was Andy Lapham

    Anne Atwater's dissertation work (Univ. of Wisonsin, 1970) compared 5
    skilled men, 5 skilled women & 5 average women. They were classified based
    upon ball speed at release and all threw overhand. The dissertation is
    available from Univ. Microforms or I would be glad to send you my copy if
    you would like to borrow it. I'll check my files to see if I uncover any
    other appropriate references.



    From: neil@isgtec.com (Neil Glossop)
    I know that Glen Fleisig at ASMI in Birmingham Al was doing some studies on
    this, but I'm not sure if it was published. In case you are not familiar
    with ASMI, it is part of James Andrews group. Let me know if you need any
    more information. (Just found their tel no.:205-918-0000 and 205-918-0800)



    From: Marc Takeno
    I recall a great article on the pitching of a curve ball in the magazine
    "Science '89" (or '86? '87? '88? sorry, can't remember!). The magazine
    wasn't too rigorous; it was geared more toward the layman or popular
    science crowd. However, the article had some great pictures and a general
    discussion about pitching mechanics. There may even have been a
    bibliography at the end of the article. The best place to start would be in
    a index such as "Reader's Guide to Periodical Literature". Good luck!

    I am currently writing my literature review for my master's thesis on
    throwing and have quite a few articles. I am not concerned with gender
    differences at this time, but I believe there are a lot of references out
    there. A few of the articles you might be interested in are listed below.

    elbow isokinetic peak torque, torque acceleration energy, average power,

    From: Duane Knudson
    There has been a great deal of research on overarm throwing at the
    University of Wisconsin. (Rose Bowl!??) The classification used in some
    recent Ph.D. work for ball velocity is:
    Skilled Men 33 to 38 m/s
    Skilled Women 21-24 m/s
    Average Men 22-30 m/s
    Average Women 12-20 m/s
    Unskilled Men < 22 m/s
    Unskilled Women
