HUBUNGAN TINGKAT KEBUGARAN KARDIORESPIRASI DAN KEKUATAN GENGGAMAN TANGAN DENGAN SINDROM METABOLIK

Abstract

Background: The metabolic syndrome, a clustering of metabolic disorders, is associated with morbidity and all-cause mortality. WHO estimated that 23% of men and 12% of women in the world had metabolic syndrome. Several studies had examined that metabolic syndrome was associated with cardiorespiratory fitness and handgrip strength. Aim: To investigate the association of cardiorespiratory fitness and handgrip strength with metabolic syndrome. Methods: This cross-sectional study included 31 subjects (23 women and 8 men), aged 40 to 70. Cardiorespiratory fitness was measured by Harvard step test. Handgrip strength was measured with a handgrip dynamometer. NCEP ATP III guideline was used to determine the metabolic syndrome diagnosis. Results: About twenty-five percent (25,81%) of 31 samples had metabolic syndrome. A higher percentage was observed in subjects with low cardiorespiratory fitness levels. The same number was observed in subjects with low and normal handgrip strength. Spearman correlation test between cardiorespiratory fitness and metabolic syndrome along with Fisher’s exact test between cardiorespiratory fitness categories and metabolic syndrome showed no significant correlation. Meanwhile, Spearman correlation test between handgrip strength and metabolic syndrome showed a significant inverse correlation (r=-0,373; p=0,039). Furthermore, Fisher’s exact test also showed a significant correlation between handgrip strength categories and metabolic syndrome (p=0,026; prevalence ratio 4,17). Conclusions: There was no significant correlation between cardiorespiratory fitness and metabolic syndrome. Metabolic syndrome was inversely correlated with handgrip strength. Keywords: Metabolic syndrome, cardiorespiratory fitness, handgrip strength
