Previous studies had shown that experienced tai chi practitioners had better joint proprioception and balance control during weight shifting. The objective of the present study was to examine whether experienced golfers had attained similar improvement when compared with the tai chi practitioners, healthy elderly subjects and young university students. The authors compared 12 experienced elderly tai chi practitioners with 11 experienced elderly golfers, 12 healthy elderly subjects and 12 young university students, who were all males, using: (i) passive knee joint repositioning test to assess their joint proprioceptive acuity and (ii) limits of stability test to assess their ability to voluntarily weight shift within their base of support. Both tai chi practitioners and golfers had better knee joint proprioceptive acuity than did the elderly control subjects. Of special interest is that their performance was similar to that of the young subjects. Within the limits of the stability test, tai chi practitioners and golfers had faster reaction times, leaned further without losing stability and showed better control of leaning trajectory than did elderly control subjects.
