Why the study?
Does long-term training (racket playing) alter cardiac vagal withdrawal (R-R interval changes) at the onset of passive and voluntary movement?
Population
18 male volunteers, divided into 9 controls and 9 racket players
Comparison
10 s of voluntary and passive movement… vs Control subjects and intra-subject comparison of…

Preserved mechanoreflex vagal withdrawal in trained athletes warrants no practice change; leaves open training effects on autonomic reflexes.
Does long-term training (racket playing) alter cardiac vagal withdrawal (R-R interval changes) at the onset of passive and voluntary movement?
Cardiac vagal withdrawal induced by muscle mechanoreflex stimulation is well-maintained despite long-term exposure to training.
Vianna et al. (2008) studied this question.
