Abstract
Background. It is unclear how the effect of training core muscles during low back pain in athletes affects their respiratory function after returning to performance.
Aims. The purpose of this study was to examine differences in the abdominal core muscles, endurance, and respiratory function among players with a history of lumbar spondylolysis.
Methods. The Subjects were 94 healthy high school students who played soccer football. This study was a cross-sectional study that compared and analyzed results based on data collected at a single point in time. Measurement items were maximal oxygen uptake, respiratory function (lung capacity, % effort lung capacity, and one-second rate), and abdominal trunk muscle strength. The correlations between items were examined using Spearman’s rank correlation coefficient. All analyses were performed for all subjects, for the group with a history of previous lumbar spondylolysis, and for the group with no history. Additionally, multiple regression analysis was conducted to investigate factors associated with maximal oxygen uptake.
Results. In the total and the non-history group, maximal oxygen uptake showed significant moderate correlations with age, body weight, and vital capacity. In contrast, such relationships were not observed in the history group, where maximal oxygen uptake exhibited a significant moderate to high correlation only with trunk muscle strength (r = 0.586). The results of the multiple regression analysis showed no significant differences.
Conclusions. The findings that improved abdominal core function due to a history of lumbar spondylolisthesis which influence endurance after returning to sport is of considerable significance.
