Regular Strength and Sprint Training Counteracts Bone Aging: A 10‐Year Follow‐Up in Male Masters Athletes

چکیده
Cross-sectional and interventional studies suggest that high-intensity strength impact-type training provide a powerful osteogenic stimulus even in old age. However, longitudinal evidence on the ability of to attenuate age-related bone deterioration is currently lacking. This follow-up study assessed role continued sprint aging 40- 85-year-old male sprinters (n = 69) with long-term background. Peripheral quantitative computed tomography (pQCT)-derived structural, strength, densitometric parameters distal tibia midshaft were at baseline 10 years later. The groups well-trained (actively competing, including ≥2 times/week; n 36) less-trained (<2 times/week, no training, switched endurance training; 33) athletes formed according self-reports follow-up. Longitudinal changes traits two examined using linear mixed models. Over 10-year period, group-by-time interactions found for total mineral content (BMC), trabecular volumetric density (vBMD), compressive index, mid-tibia cortical cross-sectional area, medullary BMC, BMC anterior posterior sites (polar mass distribution analysis) (p < 0.05). These reflected maintained (distal tibia) or improved (mid-tibia) properties decreased over period.

In conclusion, our findings indicate associated tibial middle-aged older athletes, suggesting regular, intensive exercise counteracts aging. © 2021 Authors.

Effects of whole body vibration training on muscle strength and sprint performance in sprint-trained athletes.
Despite the expanding use of Whole Body Vibration training among athletes, it is not known whether adding Whole Body Vibration training to the conventional training of sprint-trained athletes will improve speed-strength performance. Twenty experienced sprint-trained athletes (13 male symbol, 7 female symbol, 17-30 years old) were randomly assigned to a Whole Body Vibration group (n=10: 6 male s...
متن کاملBone mineral density and bone turnover in male masters athletes aged 40-64.
We evaluated areal bone mineral density (aBMD), bone mineral content (BMC), and markers of bone turnover in male competitive masters athletes representing different training profile in the past and at present, aged 40-64 (14 endurance runners, and 12 speed-power athletes), and non-sport controls (n = 13). Dual-energy X-ray absorptiometry measurements of total body and regional aBMD, BMC and sof...

Methods and Results-—We studied 1462 participants in Bambu ı City, Brazil, with electrocardiogram (ECG) records classified by the Minnesota Code. Follow-up time was 10 years; the endpoint was mortality. Adjustment for potential confounding variables included age, gender, conventional risk factors, and B-type natriuretic peptide (BNP). The mean age was 69 years (60.9% women). The prevalence of C...

Participation of masters athletes (>30 years) in sprint running (100-400 m) and sprint track cycling (200 m, team sprint, 1-km) has increased significantly over recent decades. With aging, sprint and endurance performance gradually declines. The present review focuses upon the effects of resistance training on sprint and endurance performance and its physiological determinants in masters athlet...
