“…Other researchers developed multilevel models to account for the dependence of environmental variables but ignored the dependence of individual variables [ 9 , 14 , 15 ]. However, multiple individual variables such as components of walking capacity (i.e., comfortable and fast gait speed, walking endurance, leg strength, balance capacity, and self-reported walking self-efficacy) are correlated [ 16 – 18 ], as are different environmental variables such as land use diversity and residential density [ 19 , 20 ]. Although the correlation among individual/environmental variables may not be high enough to cause collinearity problems when using aforementioned methods, it is important to take the correlation into consideration when building a model.…”

Objective To estimate the relationships between individual and environmental variables and outdoor walking (OW) in older adults with OW limitations through verifying a conceptual model. Methods Baseline data from 205 older adults participating in a randomized trial of a park-based OW program were analyzed using structural equation modeling. We evaluated a three latent factor model: OW (accelerometry and self-report); individual factors (balance; leg strength; walking self-confidence, speed and endurance; mental health; education; income; car access); and environmental factors (neighbourhood walkability components). Results Mean age was 75 years; 73% were women. Individual factors was significantly associated with OW (β = 0.39, p < .01). Environmental factors was not directly associated with OW but was indirectly linked to OW through its significant covariance with the individual factors (β = 0.22, p < .01). The standardized factor loadings from the individual factors on walking self-confidence and walking capacity measures exceeded 0.65. Conclusions Better walking capacity and more confidence in the ability to walk outdoors are associated with higher OW in older adults. Better neighbourhood walkability is indirectly associated with more OW. The conceptual model demonstrates an individual and environment association; if the capacity of the individual is increased (potentially through walking interventions), they may be able to better navigate environmental challenges.

“…The progressive decline in muscle power with aging may compromise mobility and independence, and thus bears important functional consequences 13 ) . A decline in lower limb muscle power may also represent an important risk factor for falls 12 , 16 , 17 , 18 , 19 , 20 ) . During stretch-shortening cycle (SSC) movements, muscle power can be enhanced by concentric muscle actions preceded by active muscle stretching (eccentric muscle actions), in comparison with concentric muscle actions preceded by a resting or isometric state 15 ) .…”

To examine the effects of age and gender in an ageing population with respect to functional decline and the relationship between muscle power and functional capacity. [Participants and Methods] The cohort (N=154) was subdivided into youngest-old (65-70 years.; n=62), middle-old (71-75 years.; n=46), and oldest-old (76-81 years.; n=46). Measures of mechanical muscle function included countermovement jump height, muscle power, leg strength and grip strength. Functional performance-based measures included heel-rise, postural balance, Timed Up and Go, and gait speed. [Results] The oldest-old performed significantly worse than the middle-old, whereas the youngest-old did not outperform the middle-old to the same extent. Increased contribution of muscle power was observed with increasing age. Males had consistently higher scores in measures of mechanical muscle function, whereas no gender differences were observed for functional capacity. [Conclusion] The age-related decline in functional capacity appears to accelerate when approaching 80 years of age and lower limb muscle power seems to contribute to a greater extent to the preservation of functional balance and gait capacity at that stage. Males outperform females in measures of mechanical muscle function independent of age, while the findings give no support for the existence of gender differences in functional capacity.

“…dynamic balance-a state in which a robust complex system will self-correct in response to imbalance (resulting from perceived variation/challenge) to maintain functional organization, or the individual and coordinated expression of balance and imbalance (Cowen, Nesti, & Cheetham, 2014). Dynamic balance also has a positive relationship with the lower body strength in adults (Shim, Harr, & Waller, 2018).…”

The aim of this research was to determine the direct and indirect effect as well as the simultaneous effect of exogenous variables with endogenous variables. The research method used was an associative quantitative approach using test and measurement techniques. The data analysis technique used was a path analysis approach. The population in this research was all of POPB DKI Jakarta athletes in 2021 totaling 20 people. The sampling technique used was total sampling so that the number of samples in this research was 20 people consisting of 10 women and 10 men. The skills of Dollyo Chagi Kick Taekwondo used the Dollyo Chagi Kick skills test. The balance used a modified bass test. The concentration used a concentration grid test. The instrument of eye-foot coordination used a smart speed pro coordination test. The results showed that the direct effect of variable X1 on Y = 0,243. The direct effect of variable X2 on Y = 0,567. The direct effect of variable X3 on Y = 0,378. The direct effect of variable X1 on X3 = 0,706. The direct effect of variable X2 on X3 = 0,297. The indirect effect of variable X1 on Y through X3 = 0,706 x 0,378 = 0,267. The indirect effect of variable X2 on Y through X3 = 0,297 x 0,378 = 0,113.
