Sarcopenia and Covid-19: A New Entity?
2021
As the world comes into terms with the persistent existence of the coronavirus disease 19 (COVID-19) pandemic, the scientific and medical communities have started shifting their attention to the long-term side effects of the disease. Specialists have acknowledged that numerous COVID-19 survivors, especially those who suffered severe complications and endured prolonged bedrest, may require continuous monitoring and rehabilitative care. In this chapter, the authors discuss factors that may predispose individuals to acute sarcopenia secondary to COVID-19 infection or sarcopenic obesity secondary to altered diet and physical activity from prolonged confinement. Challenges in nutrition are highl…
Traditional vs daily undulling periodization in strength and local muscle endurance gains on trained men
2018
The aim of this study was to investigate the impact of different periodization models on strength and local muscle endurance. Twenty trained men (25.45 ± 2.984 years, 75.34 ± 6.05 kg, 177.25 ± 4.92 cm, 23.96 ± 1.64 kg . m-2) were randomly assigned in two groups: undulling periodization (UPG) and traditional periodization group (TPG), respectively. All the subjects performed one repetition maximum (1-RM) strength test and a local muscle endurance test (60% of 1-RM to failure) before, during and after experimental period. The UPG executed 30 workout sessions with daily modifications regarding intensity, volume and rest period length. The TGP was divided into 3 phases (10 workout sessions in e…
Survival and developmental milestones among Pompe registry patients with classic infantile-onset Pompe disease with different timing of initiation of…
2014
s S62 strength in the arms (pulls self to stand: 72% vs 47%) and legs (bears weight on legs: 79% vs 66%). Results were similar when patients from Taiwan, who may have been identifi ed by newborn screening and not clinical diagnosis, were excluded. Earlier initiation of ERT in classic IOPD patients appears to improve the chances of survival and leads to better retention of muscle strength and improvement of symptoms in these young patients affected most severely by Pompe disease.
Effect of oral magnesium supplementation on physical performance in healthy elderly women involved in a weekly exercise program: A randomized control…
2014
Background: Magnesium deficiency is associated with poor physical performance, but no trials are available on how magnesium supplementation affects elderly people’s physical performance. Objective: The aim of our study was to investigate whether 12 wk of oral magnesium supplementation can improve physical performance in healthy elderly women. Design: In a parallel-group, randomized controlled trial, 139 healthy women (mean 6 SD age: 71.5 6 5.2 y) attending a mild fitness program were randomly allocated to a treatment group (300 mg Mg/d; n = 62) or a control group (no placebo or intervention; n = 77) by using a computer-generated randomization sequence, and researchers were blinded to their …
Magnesium and muscle performance in older persons: the InCHIANTI study1–3
2006
BACKGROUND The role of magnesium in maintaining muscle integrity and function in older adults is largely unknown. OBJECTIVE We aimed to investigate the relation between serum magnesium concentrations and muscle performance in older subjects. DESIGN Data are from the baseline examination conducted between September 1998 and March 2000 of the InCHIANTI (aging in the Chianti area) study, a prospective epidemiologic survey of risk factors for late-life disability. From among 1453 randomly selected community residents completing a home interview, 1138 men (46%) and women (aged 66.7 +/- 15.2 y; x +/- SD) with complete data on muscle performance and serum magnesium who were not severely cognitivel…
Nutrition and physical activity in the prevention and treatment of sarcopenia: systematic review
2017
Summary This systematic review summarizes the effect of\ud combined exercise and nutrition intervention on muscle mass\ud and muscle function. A total of 37 RCTs were identified.\ud Results indicate that physical exercise has a positive impact\ud on muscle mass and muscle function in subjects aged 65 years\ud and older. However, any interactive effect of dietary supplementation\ud appears to be limited.\ud Introduction In 2013, Denison et al. conducted a systematic\ud review including 17 randomized controlled trials\ud (RCTs) to explore the effect of combined exercise and\ud nutrition intervention to improve muscle mass, muscle\ud strength, or physical performance in older people.\ud They c…
Ankle muscle strength discriminates fallers from non-fallers
2014
International audience; It is well known that center of pressure (CoP) displacement correlates negatively with the maximal isometric torque (MIT) of ankle muscles. This relationship has never been investigated in elderly fallers (EF). The purpose of this study was thus to analyze the relationship between the MIT of ankle muscles and CoP displacement in upright stance in a sample aged between 18 and 90 years old that included EF . The aim was to identify a threshold of torque below which balance is compromised. The MIT of Plantar flexors (PFs) and dorsal flexors (DFs) and CoP were measured in 90 volunteers: 21 healthy young adults (YA) (age: 24.1 +/- 5.0), 12 healthy middle-aged adults (MAA)…
Tensiomyography reliability and prediction of changes in muscle force following heavy eccentric strength exercise using muscle mechanical properties
2015
AbstractThe current study involved the completion of two distinct experiments. Experiment 1 analyzed the inter-day reliability of tensiomyography (TMG) muscle mechanical properties based on the amplitude of the muscle belly radial deformation, the time it takes to occur, and its velocity under maximal and submaximal stimuli, in the muscles rectus femoris, biceps femoris, and gastrocnemius lateralis, from 20 male sport students. Experiment 2 investigated whether changes in maximal voluntary isometric contraction (MVIC) could be predicted based on changes in TMG properties following 24 h after different squat training protocols (MS = multiple sets; DS = drop sets; EO = eccentric overload; FW …
Muscle Evaluation in Axial Spondyloarthritis—The Evidence for Sarcopenia
2019
Sarcopenia is a syndrome defined as a progressive and generalized skeletal muscle disorder associated with an increased likelihood of adverse outcomes such as falls, fractures, physical disability, and death. The actual definition of sarcopenia is based on a reduction in the values of three parameters: strength, muscle mass quantity or quality, and physical performance (the determinant of severity). Muscle wasting is a common feature in several chronic diseases, such as spondyloarthritis (SpA), and significantly increases patient morbidity and mortality. Although there has been huge progress in this field over recent years, the absence of a clear definition and clear diagnostic criteria of …
