Impact of Habitual Exercise on Locomotive Function of Middle-aged and Elderly Volunteers: A Longitudinal Study

Relationship between the 25-question Geriatric Locomotive Function Scale and physical function in the elderly people

INTRODUCTION

Locomotive syndrome (LS) is a condition of reduced mobility. The LS stage can be determined by the stand-up test, two-step test, and 25-question geriatric locomotive function scale (GLFS-25). This study aimed to establish whether the LS stage can be reliably determined using the GLFS-25, and to clarify the correlation between the GLFS-25's six subcategories and physical functions.

MATERIALS AND METHODS

We administered the GLFS-25 and evaluated physical functions using the stand-up test, the two-step test, handgrip strength, the five-times sit-to-stand test, the 4 m walking test, and the duration of single leg standing. We assessed 103 participants over 65 years of age. We analyzed the correlation between LS stage and GLFS-25 score, as well as the correlations between physical functions and the GLFS-25's six subcategories.

RESULTS

There was a discrepancy between the LS stage determined using the GLFS-25 alone and the LS stage determined using all three tools. ROC analysis revealed a cut-off value of 6 for the discrimination of LS stages 0/1 and 14 for stages 1/2. The analysis revealed an AUC of 0.78 and 0.81, respectively. Among the six subcategories of the GLFS-25, movement-related difficulty, usual care, ADL, and social activities were correlated with mobility functions. In contrast, body pain and cognitive showed no correlation.

CONCLUSION

The GLFS-25 is useful for screening those with severe LS stages; however, evaluation of actual physical function is recommended for precise staging of LS in those with low GFLS-25 scores. Among the six subcategories of the GLFS-25, body pain and cognitive were independent of the other four subcategories.

Frequency-Response Relationship Between Exercise and Locomotive Syndrome Across Age Groups: Secondary Analysis of a Nationwide Cross-Sectional Study in Japan

OBJECTIVES

This study aimed to clarify the frequency-response relationship between exercise habits and locomotive syndrome in different age groups.

METHODS

We analyzed 8,681 independent community dwellers who participated in a nationwide cross-sectional locomotive syndrome study. Participants were divided into young (20-39 years), middle (40-64 years), and old (≥ 65 years) groups. The presence of locomotive syndrome was evaluated using the locomotive syndrome risk tests. Exercise habits were assessed by exercise frequency (almost every day/sometimes/occasionally/never). The association between locomotive syndrome and exercise was assessed using the multiple logistic regression analysis adjusted for participant characteristics for each age category.

RESULTS

Overall, 3,528 (41%) participants had locomotive syndrome. In the old group, the risk of locomotive syndrome was lower with an increased exercise frequency. However, this dose-response relationship was not found in the young group. The proportion of locomotive syndrome was lower even in participants who occasionally exercised (1-3 days/month) than those who never exercise in the young and middle age groups.

CONCLUSIONS

Regular exercise reduced the risk of locomotive syndrome not only in middle and older adults but also in young adults. Moreover, increasing exercise frequency may provide benefits for locomotive syndrome prevention, especially among older adults.
