073 (95% CI 1.053, 1.094) and 1.151 (95% CI 1.132, 1.171), respectively; for visual acuity between 20/60 and 20/200, 1.236 (95% CI 1.197, 1.277), and 1.336 (95% CI 1.302, 1.371), respectively; and for visual acuity worse than 20/200, 1.325 (95% CI 1.285, 1.366) and 1.383 (95% CI 1.349, 1.418), respectively.Conclusion Subjects with lower VA had higher risks of acute myocardial infarction and stroke. These results suggest that low VA is an independent risk factor for CVD.The purpose of the present study was twofold (i) to compare the kinematic characteristics of individual and relay swimming starts; and (ii) to relate the kinematic variables to 5 m performance for both starts. Twelve elite-level swimmers performed 2 × 25 m at maximal effort (one with an individual and one with a relay start randomly). Two-dimensional direct linear transformation algorithms were used to calculate swimmers' centre of mass (CM) kinematics during each subphase. The results indicated moderate to much faster 5 m, 10 m 15 and 15 m times (29.4, 10.7 and 6.5%) for relay than individual starts as well as the differences at specific parameters, but no differences in take-off horizontal velocity between start techniques. Large correlations to performance times were found in block time, horizontal take-off velocity, take-off velocity and entry angle (r = 0.77 to 0.83) 20 for individual start, but in changeover time, take-off height and entry distance (r = 0.69 to 0.90) for relay start. Differences on swim start regulations between individual and relay events were in line with different key parameters related to start performances in each event. This should be considered by swimmers and coaches when addressing the starting improvement.Background Older adults with heart disease (HD) are more likely to report a higher prevalence of falls compared to those without HD. A knowledge gap currently exists regarding the factors associated with fear of falling (FOF) among older adults with HD. Therefore, this study aimed to estimate FOF and identify factors associated with FOF among older adults with HD. Methods Data came from a secondary analysis of the International Mobility in Aging Study (IMIAS) baseline (2012) data. FOF was measured using the Falls Efficacy Scale-International (FES-I). Stepwise linear regression was used to identify factors associated with FOF. Results A total of 429 participants identified themselves as having heart disease diagnosed by their physician (mean age 69.5 ± 2.9). Older adults with HD reported on average (25.6) higher FOF than those without HD. For older adults with HD, FES-I increased significantly by 1.3, 1.0, and 0.6 points, when the Short Physical Performance Battery, the Leganes Cognitive Test, and QOL total scores decreased by one point. FES-I also significantly increased by 3.2 when income was insufficient compared to sufficient or very sufficient income. Discussion FOF is multifactorial, and our findings provide a base for developing future management rehabilitation intervention programs aimed at decreasing FOF among older adults with HD.Despite its increasing popularity, swing dancing has not been fully studied biomechanically, imposing challenges in understanding the movement patterns associated with swing dancing. The purpose of this study was to examine the biomechanics of the triple step, one of the most common swing dance elements. We intended to determine whether dancing with a partner affects kinetic measurements and if these measurements are different among the three steps. Eight recreational swing dancers completed three triple steps to the right and the left with and without a partner. The loading rate of the vertical ground reaction force was calculated for each step, and bilateral lower limb joints moments and powers were determined. Results illustrated that dancing with or without a partner has limited effect on the kinetic measurements. However, the outcome measurements differed among the steps a higher peak vertical ground reaction force during the first and second steps, a greater loading rate during the second step, and the greatest joint power absorption at the ankle and knee during the second step were observed. see more The findings extend our understanding of the biomechanics of swing dancing, and could provide preliminary guidance for understanding swing dance-related injuries and improving performance of swing dancing.CREG1 (cellular repressor of E1A-stimulated genes 1) is involved in tissue homeostasis and influences macroautophagy/autophagy to protect cardiovascular function. However, the physiological and pathological role of CREG1 in the skeletal muscle is not clear. Here, we established a skeletal muscle-specific creg1 knockout mouse model (creg1;Ckm-Cre) by crossing the Creg1-floxed mice (Creg1fl/fl) with a transgenic line expressing Cre recombinase under the muscle-specific Ckm (creatine kinase, muscle) promoter. In creg1;Ckm-Cre mice, the exercise time to exhaustion and running distance were significantly reduced compared to Creg1fl/fl mice at the age of 9 months. In addition, the administration of recombinant (re)CREG1 protein improved the motor function of 9-month-old creg1;Ckm-Cre mice. Moreover, electron microscopy images of 9-month-old creg1;Ckm-Cre mice showed that the mitochondrial quality and quantity were abnormal and associated with increased levels of PINK1 (PTEN induced putative kinase 1) and PRKN/PARKI dynamin 1-like; FCCP carbonyl cyanide p-trifluoro-methoxy phenyl-hydrazone; HSPD1/HSP60 heat shock protein 1 (chaperonin); IP immunoprecipitation; MAP1LC3B/LC3B microtubule-associated protein 1 light chain 3 beta; MFF mitochondrial fission factor; MFN2 mitofusin 2; MYH1/MHC-I myosin, heavy polypeptide 1, skeletal muscle, adult; OCR oxygen consumption rate; OPA1 OPA1, mitochondrial dynamin like GTPase; PINK1 PTEN induced putative kinase 1; PPARGC1A/PGC-1α peroxisome proliferative activated receptor, gamma, coactivator 1 alpha; PRKN/PARKIN parkin RBR E3 ubiquitin protein ligase; PTGS2/COX2 prostaglandin-endoperoxide synthase 2; RFP red fluorescent protein; RT-qPCR real-time quantitative PCR; SQSTM1/p62 sequestosome 1; TFAM transcription factor A, mitochondrial; TOMM20 translocase of outer mitochondrial membrane 20; VDAC voltage-dependent anion channel.
