文摘

To evaluate possible changes in spinal curvature over a period of 5 years of an elite cross-country skiing squad, and to study whether there are any differences in this respect between individuals who report low back pain and those how do not.

Participants

Fifteen young cross-country skiers (M age=13.6±0.9) participated voluntarily throughout the entire study period.

Main outcome measures

Debrunner's kyphometer was used for measuring the difference between thoracic kyphosis and lumbar lordosis of the spine. All subjects also answered a questionnaire including questions about ski-related low back pain, the amount of ski training, and participation in other sports.

Results

The results at the end of the 5-year period comprise data from 15 skiers (M age=18.5±0.9 years). The relationship between thoracic kyphosis and lumbar lordosis increased from 3.5° to 13.1°, respectively (c89b6382ecf1d21a57385dc29cccdce"" title=""Click to view the MathML source"">p=0.0001). Of the 15 elite cross-country skiers, seven reported low back pain at the 5-year examination. At the 5-year follow-up, skiers with low back pain showed significantly higher relationship between thoracic kyphosis and lumbar lordosis than did those skiers without low back pain, 18.2° and 10.5°, respectively (c8766bd26752eec6f08dca10"" title=""Click to view the MathML source"">p=0.035). Of the eight elite cross-country skiers without low back pain, seven were also involved in other sports (p=0.005).

Conclusions

Based on these findings, our advice is that adolescent cross-country skiers also should participate in other physical activities besides cross-country skiing.
