Effect of training on postural control in figure skaters: a randomized controlled trial of neuromuscular versus basic off-ice training programs.
OBJECTIVE
To compare the effect of a neuromuscular training program and a basic exercise program on postural control in figure skaters.


METHODS
Two groups; parallel design; prospective, randomized controlled trial.


METHODS
Postural control laboratory, arenas, September 2001 to December 2002.


METHODS
Forty-four young, healthy figure skaters (18 years +/- 3 years).


METHODS
Participants were randomly assigned to receive a neuromuscular training program (n = 22) or a basic exercise training program (n = 22). Both programs were completed 3 times per week for 4 weeks, and each session was supervised.


METHODS
Participants completed baseline and postintervention measures of postural control on a force plate. Postural control was quantified as the center of pressure (CoP) path length during tests of single-limb standing balance that mimicked figure skating skills and challenged the postural control system to varying degrees. The primary outcome measure was the CoP path length observed during a landing jump test completed with eyes closed.


RESULTS
The post intervention CoP path lengths during the more challenging tests were significantly (P < 0.05) lower (indicating better postural control) for the neuromuscular trained group than for the basic exercise-trained group. For the landing jump test completed with eyes closed, the percent improvement in the neuromuscular trained group was significantly greater (mean = 21.0 +/- 22.0%) than the basic exercise trained group (mean = -4.9 +/- 24.9%; P < 0.05). The magnitude of improvement in the neuromuscular-trained group ranged from approximately 1% to 21%, depending on the specific postural control test used.


CONCLUSIONS
The results suggest that off-ice neuromuscular training can significantly improve postural control in figure skaters, whereas basic exercise training does not.
