Comparisons Of Functional Movement Screen Values In Different Weight Populations

Abstract

PURPOSE: In this study, we explored the mechanism of overweight and obesity on functional exercise ability through correlating functional movement screen (FMS) with BMI, and comparing FMS values among different weight groups. METHODS: FMS was performed in 481 adults (male 209, female 272) aged 20 to 69. The FMS consists of 7 modes of action: deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push up and rotary stability. The total score of FMS is 21 points. The BMI grading criteria of Chinese people was used. RESULTS: (1) BMI was negatively correlated with the total score of FMS, and the correlation coefficient was - 0.309 (P < 0.01). The correlation coefficients of BMI with shoulder mobility and rotary stability were -0.404 and -0.311 (P < 0.01), respectively. (2) If BMI exceeded 26 kg/m2, the total score showed a downward trend. The decline was most obvious when exceeded 31 kg/m2. (3) The total FMS score of obese group was significantly lower than that of normal weight and overweight group (P < 0.01), and that of overweight group was significantly lower than that of normal weight group (P < 0.01). (4) The scores of shoulder mobility and rotary stability of obese people were significantly lower than those of normal weight and overweight people (P < 0.01). The scores of active straight leg raise in obese group were significantly lower than normal weight group (P < 0.01). (5) There was significant difference in the score distribution of in-line lunge (χ 2 = 13.097, P = 0.011), the proportion of 1 point is the highest in obese people, and the proportion of 3 points from high to low is normal weight, overweight and obese people. The scores of shoulder mobility and active straight leg raise were significantly different among the three groups (χ 2 = 61.661, P = 0.000; χ 2 = 14.852, P = 0.005), the proportion of 3 points from high to low was normal weight, overweight and obese people. There was also a significant difference in the distribution of rotary stability scores (χ 2 = 34.388, P = 0.000). CONCLUSION: BMI was negatively correlated with FMS performance, and the order of FMS performance from good to bad was normal weight, overweight and obese people. Among the three groups, the most obvious differences were shoulder mobility, rotary stability and active straight leg raise.
