This study examined the concurrent age-related differences in muscle and tendon structure properties. Achilles morphology mechanical properties triceps surae architecture were measured from 100 subjects [33 young (24 ± 2 yr) 67 old (75 3 yr)]. Motion analysis-assisted ultrasonography was used to determine stiffness, Young's modulus, hysteresis during isometric ramp contractions. Ultrasonography measure architectural features size cross-sectional area. Older participants had 17% lower (P <...
Abstract Background Handgrip strength (HGS) is used to identify individuals with low muscle (dynapenia). The influence of the number attempts on maximal HGS not yet known and may differ depending age health status. This study aimed assess how many are required obtain HGS. Methods Three cohorts (939 individuals) differing in status were included. was assessed three times explored as continuous dichotomous variable. Paired t ‐test, intraclass correlation coefficients (ICC) Bland–Altman...
Objective This study compared bioimpedance analysis (BIA) in the assessment of body composition with dual‐energy X‐ray absorptiometry (DXA) 18‐ to 88‐year‐old adults. Design and Methods Body 882 adults was estimated by eight‐polar BIA DXA. In addition, estimates lean mass, fat percentage were investigated across a range age leisure time physical activity (LTPA) groups. Results Compared DXA, larger masses (mean difference 2.9 1.6 kg) smaller (3.1 2.6 both women men, respectively. Differences...
It has been postulated that human tendons are viscoelastic and their mechanical properties time-dependent. Although Achilles tendon (AT) mechanics widely reported, there is no consensus about AT such as loading rate dependency or hysteresis, in vivo. force-elongation characteristics were determined from 14 subjects an ankle dynamometer at different rates using motion capture assisted ultrasonography. stiffness elongation between 10 - 80% of maximum voluntary contraction (MVC) force fast slow...
cognitive deterioration and reductions of bone health coincide with increasing age. We examine the relationship between composition plasma markers remodelling measures performance in healthy adults. this cross-sectional study included 225 old (52% women, mean age: 74.4 ± 3.3 years) 134 young 23.4 2.7 adult participants from MyoAge project. Whole body mineral density was measured by dual-energy X-ray absorptiometry. Blood analyses a panel bone-related peptides (dickkopf-1, osteoprotegerin,...
Muscle mass, strength, and power are known determinants of mobility in older adults but there is limited knowledge on the influence muscle architecture or tendon properties mobility. The purpose this study was to examine relationship between plantarflexor muscle–tendon healthy adults. A total 52 subjects (age 70–81 years) were measured for 6-minute walk test (6MWT), timed "up go"-test (TUG), isometric plantarflexion Achilles stiffness, triceps surae architecture, lower extremity lean leg...
Previous studies have shown that aging is associated with alterations in muscle architecture and tendon properties (Morse CI, Thom JM, Birch KM, Narici MV. Acta Physiol Scand 183: 291-298, 2005; MV, Maganaris CN, Reeves ND, Capodaglio P. J Appl 95: 2229-2234, 2003; Stenroth L, Peltonen J, Cronin NJ, Sipila S, Finni T. 113: 1537-1544, 2012). However, the possible influence of different types regular exercise loading on older adults poorly understood. To address this, triceps surae...
Abstract Abnormal mechanical loading is essential in the onset and progression of knee osteoarthritis. Combined musculoskeletal (MS) finite element (FE) modeling a typical method to estimate load distribution tissue responses joint. However, earlier combined models mostly utilize static-optimization based MS muscle force driven FE typically use elastic materials for soft tissues or analyze specific time points gait. Therefore, here we develop an electromyography-assisted model with...
Joint tissue mechanics (e.g., stress and strain) are believed to have a major involvement in the onset progression of musculoskeletal disorders, e.g., knee osteoarthritis (KOA). Accordingly, considerable efforts been made develop finite element (MS-FE) models estimate highly detailed that predict cartilage degeneration. However, creating such is time-consuming requires advanced expertise. This limits these complex, yet promising, MS-FE research applications with few participants makes...
SUMMARY Overuse-induced injuries have been proposed as a predisposing factor for Achilles tendon (AT) ruptures. If tendons can be overloaded, their mechanical properties should change during exercise. Because there data are lacking on the effects of single bout long-lasting exercise AT properties, present study measured stiffness before and after marathon. was determined slope force–elongation curve between 10 80% maximum voluntary force. characteristics were in an ankle dynamometer using...
ABSTRACT Purpose Anterior cruciate ligament injury increases the risk of knee osteoarthritis, possibly via early onset pain and changes in musculoskeletal function. This study compared muscle strength movement biomechanics during walking forward lunge between individuals with without after anterior reconstruction. Methods Cross‐sectional including participants at least 3 years post reconstruction, aged 18–40 time surgery, body mass index ≤30. Symptomatic were defined by a score...
