However, evidence on how different intensities and durations of physical activity (PA) influence NHHR remains scarce, particularly in aging populations. Methods: Data were obtained from China Health and Retirement Longitudinal Study. PA was self-reported and categorized as high- (HPA), moderate- (MPA), or low-intensity (LPA). Multivariable linear regression models assessed associations between PA and NHHR, with subgroup, sensitivity, and dose-response analyses further exploring robustness. Cox regression and mediation analyses examined the associations of PA and NHHR with 10-year all-cause mortality. Results: Higher levels of total, moderate-, and high-intensity PA were significantly associated with lower NHHR. The results were generally consistent with a graded pattern, with lower NHHR observed at higher activity durations, particularly for moderate-to-vigorous activity. Exploratory mediation analyses suggested that NHHR may partially account for the inverse association between PA and mortality. Conclusions: This study adds large-scale, population-based evidence on the associations between different PA intensities and NHHR. Regular moderate-to-vigorous PA is associated with more favorable lipid profiles and lower mortality risk. These findings highlight NHHR as a valuable biomarker linking physical activity to cardiometabolic health and longevity in middle-aged and older adults. 2026-06-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/211885 Title: Biomechanical analysis of Tai Chi gait and lower limb joint stability: impact on balance control Authors: Li, Jiaqi; Lee, Seongno Abstract: Background Although Tai Chi has demonstrated efficacy in improving balance and preventing falls, the underlying biomechanical mechanisms remain incompletely understood. Objectives This study aimed to examine biomechanical mechanisms associated with Tai Chi practice in relation to lower limb joint stability and balance control Methods A cross-sectional comparative study enrolled 64 participants aged 55-70 years (32 long-term Tai Chi practitioners and 32 age-matched controls). Comprehensive biomechanical assessments included 3D motion capture (200 Hz), force plate measurements (2000 Hz), 16-channel surface electromyography, and standardized balance tests. Primary outcomes were joint stability indices, center of pressure parameters, and balance performance scores. Multiple regression and mediation analyses identified relationships between joint stability mechanisms and balance outcomes. Results Compared to controls, Tai Chi practitioners demonstrated significantly greater ankle dynamic stiffness (23.8 +/- 2.4 vs. 19.5 +/- 2.8 Nm/kg/rad, p < 0.001, d = 1.72), enhanced hip-knee coordination (0.78 +/- 0.06 vs. 0.65 +/- 0.09, p < 0.001, d = 1.63), and 32.1% higher neuromuscular efficiency at the ankle joint. These adaptations correlated strongly with superior balance performance, including 32.3% smaller center of pressure excursion area during single-leg stance (p < 0.001) and 36.2% faster time-to-stabilization after perturbations (p < 0.001). Mediation analysis revealed that ankle proprioceptive acuity and dynamic joint stiffness regulation accounted for 58.4% of the relationship between Tai Chi experience and balance performance. Conclusions Long-term Tai Chi practice is associated with specific neuromuscular adaptations characterized by proximal-to-distal muscle activation sequencing, selective joint stiffness modulation, and enhanced anticipatory postural adjustments. These biomechanical mechanisms provide evidence-based foundations for optimizing Tai Chi training protocols and integrating Tai Chi principles into fall-prevention and rehabilitation programs. 2026-06-01T00:00:00Z
