Neuromuscular Adaptations after Blood Flow Restriction Training Combined with Nutritional Supplementation: A Preliminary Study

2019

Blood fl ow restriction training (BFRT) has been shown to be an eff ective alternative technique to conventional resistance training to increase skeletal muscle hypertrophy and strength. However, neuromuscular response to BFRT in combination with nutritional supplementation has rarely been studied. Th e purpose of this study was to investigate the eff ects of BFRT combined with creatine monohydrate (CrM) and/or hydroxymethyl butyrate (HMB) on skeletal muscle size and strength. Fift een healthy males were randomly divided into three groups: a) BFRT without supplementation (C-BFR); b) BFRT with CrM supplementation (0.3 g / kg-1) (CrM-BFR); and c) BFRT with CrM (0.3 g / kg-1) and HMB (3 g) sup…

Postmenopausal women with osteopenia and a healed wrist fracture have reduced physical function and quality of life compared to a matched, healthy co…

2013

Background Fractures lead to reduced physical function and quality of life (QOL), but little is known about postmenopausal women with osteopenia and a healed wrist fracture. The purpose was to evaluate physical function in terms of quadriceps strength, dynamic balance, physical capacity and QOL in postmenopausal women with osteopenia and a healed wrist fracture compared to a matched, healthy control group with no previous fracture. Methods Eighteen postmenopausal women with osteopenia (patients) (mean age 59.1 years, range 54 – 65) and a healed wrist fracture were matched to 18 healthy control subjects on age (mean age 58.5 years, range 51 – 65), height, weight and body mass index (BMI). We…

Assessment of maximal handgrip strength: how many attempts are needed?

2017

© 2017 The Authors. Background: Handgrip strength (HGS) is used to identify individuals with low muscle strength (dynapenia). The influence of the number of attempts on maximal HGS is not yet known and may differ depending on age and health status. This study aimed to assess how many attempts of HGS are required to obtain maximal HGS. Methods: Three cohorts (939 individuals) differing in age and health status were included. HGS was assessed three times and explored as continuous and dichotomous variable. Paired t-test, intraclass correlation coefficients (ICC) and Bland-Altman analysis were used to test reproducibility of HGS. The number of individuals with misclassified dynapenia at attemp…

Beyond Physical Exercise: The Role of Nutrition, Gut Microbiota and Nutraceutical Supplementation in Reducing Age-related Sarcopenia

2021

Sarcopenia is a commonly prevalent geriatric condition mainly characterized by progressive loss of the skeletal muscle mass that results in noticeably reduced muscle strength and quality. Most of the geriatric population above 60 years of age are overweight, leading to the accumulation of fat in the muscles resulting in abated muscle function. The increased loss of muscle mass is associated with high rates of disability, poor motility, frailty and mortality. The excessive degeneration of muscles is now also being observed in middle-aged people. Therefore, geriatrics has recently started shifting towards the identification of early stages of the disability in order to expand the life span o…

Effect of Calcifediol on Physical Performance and Muscle Strength Parameters: A Systematic Review and Meta-Analysis

2022

There is general agreement that optimal vitamin D status is necessary for bones, muscles, and general health, particularly in older adults, who are at higher risk of negative consequences of vitamin D deficiency, including sarcopenia; vitamin D supplementation is proposed as a potential intervention to mitigate sarcopenia. Several RCTs have reported that calcifediol (25(OH)D) was more potent than cholecalciferol in increasing plasma 25(OH)D. The present systematic review and meta-analysis aimed to summarize the effects of calcifediol on physical performance and muscle strength. We searched databases from inception to 1 January 2022 for studies investigating calcifediol on physical performan…

The effectiveness of 12 months' intensive shoulder strength training on disability, health-related quality of life and shoulder function after rotato…

2017

This study examined the effectiveness of intensive shoulder strength training on disability, health-related quality of life (HRQoL) and shoulder function in patients who had undergone rotator cuff repair (RCR). In addition, the self- report section of the American Shoulder and Elbow Surgeons Standardized Assessment Form (ASES) was cross-culturally adapted to the Finnish language and the psychometric properties of the Finnish version were assessed. Patients with a rotator cuff tear (aged 41-62 years) were randomized into an exercise group (EG, n=35) or a usual care group (UCG, n=32) after RCR. Disability was assessed with ASES questionnaire and quality of life with Short- Form 36 Health Surv…

Determinants of dynamic inspiratory muscle strength in healthy trained elderly.

2021

Background: The S-Index assessed by means of electronic devices is a measure of Inspiratory Muscle Strength (IMS) that highly correlates with the maximal inspiratory pressure (MIP). The variables involved when using regression models for the prediction of IMS/MIP depend on both the sample characteristics and the device or protocol used. In light of the scarce information on the influence of physical activity (PA) on IMS in healthy older adults (OA), together with the incorporation of new assessment devices, the objectives of this research are: 1) to determine which factors influence the IMS in a group of trained OA, using a portable electronic device; and 2) to propose a regression model to…

Optimising training adaptations and performance in military environment.

2018

Abstract Objectives Worldwide decreases in physical fitness and increases in body fat among youth have set challenges for armed forces to recruit physically capable soldiers. Therefore, knowledge of optimizing physical adaptation and performance through physical training is vital. In addition, maintaining or improving physical performance among professional soldiers in various military environments is crucial for overall military readiness. The present review focuses on the effects of military training on physical performance by searching for optimal methods to do it. Design and methods Review article based on selected literature searches using the main keywords ‘physical performance’ and ‘…

Genetics of maximal walking speed and skeletal muscle characteristics in older women.

2008

AbstractThe aim of this study was to examine whether maximal walking speed, maximal isometric muscle strength, leg extensor power and lower leg muscle cross-sectional area (CSA) shared a genetic effect in common. In addition, we wanted to identify the chromosomal areas linked to maximal walking speed and these muscle characteristics and also investigate whether maximal walking speed and these three skeletal muscle characteristics are regulated by the same chromosomal areas. We studied 217 monozygotic (MZ) and dizygotic (DZ) female twin pairs aged 66 to 75 years in the Finnish Twin Study on Aging study. The DZ pairs (94) were genotyped for 397 microsatellite markers in 22 autosomes and X-chr…
