Muscle strength according to level of physical exercise and educational background in middle-aged women in Finland.
1992
The aim of this study was to examine the role of socio-economic status and the practice of physical exercise in explaining variation in muscle strength in 50 to 60-year-old women. Consequently, four study groups combining education and physical activity were formed: (1) university education, physically active; (2) university education, sedentary; (3) vocational or lower level of education, physically active; (4) vocational or lower level of education, sedentary. Maximal isometric strength of hand grip, arm flexion, body flexion and extension as well as dynamic power of the abdominal muscles were measured in 112 women. The results of the maximal isometric strength measurements were standardi…
Lift weights to fight overweight
2014
Although resistance training (RT) has long been accepted as a means for developing and maintaining muscular strength, endurance, power and muscle mass, its beneficial relationship with health factors and chronic disease has only recently been recognized in the scientific literature. Prior to 1990, resistance training was not a part of the recommended guidelines for exercise training and rehabilitation for either the American Heart Association or the American College of Sports Medicine (ACSM). In 1990, the ACSM recognized resistance training as a significant component of a comprehensive fitness programme for healthy adults of all ages, a position subsequently confirmed few years after. At pr…
Consenso Delphi sobre el manejo de la dislipidemia en pacientes con alteración del metabolismo de la glucosa: estudio Diana
2016
Objectives The aim of the present study was to develop a multidisciplinary consensus based on the Delphi system to establish clinical recommendations for the management of dyslipidaemia when hyperglycaemia is present, and the relevant factors that should be taken into consideration when prescribing and monitoring treatment with statins. Methods The questionnaire developed by the scientific committee included four blocks of questions about dyslipidaemia in patients with impaired glucose metabolism. The results of the first two blocks are presented here: a) management of dyslipidaemia; b) relevant factors that should be taken into consideration when prescribing and monitoring treatment with s…
Evaluation of implementing a community-based exercise intervention during pregnancy
2017
Abstract Objective to evaluate the implementation of a community-based exercise intervention (the Norwegian Fit for Delivery study) during pregnancy. Design descriptive, explorative. Setting healthcare clinics in southern Norway, including urban and rural settings. Participants healthy, nulliparous women with singleton pregnancy of ≤20 gestational weeks, age ≥18 years and body mass index ≥19kg/m 2 . Methods women were randomised to either twice-weekly supervised exercise sessions combined with nutritional counselling ( n =303) or standard prenatal care ( n =303). The exercise program was based on ACOG guidelines, with the same low-impact workout for all participants, including 60minutes of …
Electrophysiological adaptations to endurance and strength training
2020
Abstract Sex differences in exercise training adaptations are still a largely unexplored field of study. There are well-known differences between men and women in terms of their average baseline fitness, such as larger muscle mass and higher cardiorespiratory fitness in men compared to women. Trained women may have a higher performance level than untrained men, but at the top end of the physical training and performance curve, i.e., where athletes are, men exhibit a higher prevalence and amplitude of sinus bradycardia and other electrophysiological changes. This chapter will explore whether men and women respond differently to a standardized training stimulus when sex differences at baselin…
Resistance Training Load Effects on Muscle Hypertrophy and Strength Gain : Systematic Review and Network Meta-analysis
2020
PURPOSE This study aimed to analyze the effect of resistance training (RT) performed until volitional failure with low, moderate, and high loads on muscle hypertrophy and muscle strength in healthy adults and to assess the possible participant-, design-, and training-related covariates that may affect the adaptations. METHODS Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, MEDLINE, CINAHL, EMBASE, SPORTDiscus, and Web of Science databases were searched. Including only studies that performed sets to volitional failure, the effects of low- (>15 repetitions maximum (RM)), moderate- (9-15 RM), and high-load (≤8 RM) RTs were examined in healthy adults. Networ…
Changes in health-related quality of life in elderly men after 12 weeks of strength training
2017
Background Muscular strength is associated with functional ability in elderly, and older adults are recommended to perform muscle-strengthening exercise. Understanding how improved muscle strength and -mass influence general and specific domains of quality of life is important when planning health promotion efforts targeting older adults. The aims of the present study were to describe changes in health-related quality of life (HRQOL) in older men participating in 12 weeks of systematic strength training, and to investigate whether improvements in muscle strength and muscle mass are associated with enhancements in HRQOL. Methods We recruited 49 men aged 60–81 years to participate in an inter…
Is global elimination of HCV realistic?
2017
The elimination of hepatitis C virus (HCV) has been made possible through the availability of new antiviral drugs which may now be administered to all patients with HCV infection, even those with decompensated cirrhosis. The goal of the World Health Organization (WHO) is to reduce the incidence of chronic hepatitis infection from the current 6-10 million to 0.9 million cases of chronic infections by 2030, and annual deaths from 1.4 million to fewer than 0.5 million. Achieving these targets will require full implementation of epidemiological knowledge of HCV infection, screening and testing practices and strategies to link HCV patients to care. This review will focus on the current state of …
Metabolic adaptation and neuroprotection differ in the retina and choroid in a piglet model of acute postnatal hypoxia.
2013
Hypoxic-ischemic insults to the neonatal brain may cause neurodevelopmental disorders. Vulnerability of different areas of the neural tissue to hypoxic-ischemic stress might be explained by either heterogeneous sensitivity to oxygen or neuroprotective capability. Our understanding of regional heterogeneity is still incomplete in terms of metabolic reconfiguration and/or activation of neuroprotective mechanisms.We studied, by western blotting, reverse-transcriptase PCR, and tandem mass spectrometry, the response of retina and choroid at protein, gene, and metabolic levels during hypoxia in a piglet model of acute postnatal hypoxia.We evidenced a metabolic shift towards glycolysis in choroid …
Heart rate variability in prediction of individual adaptation to endurance training in recreational endurance runners
2011
The aim of this study was to investigate whether nocturnal heart rate variability (HRV) can be used to predict changes in endurance performance during 28 weeks of endurance training. The training was divided into 14 weeks of basic training (BTP) and 14 weeks of intensive training periods (ITP). Endurance performance characteristics, nocturnal HRV, and serum hormone concentrations were measured before and after both training periods in 28 recreational endurance runners. During the study peak treadmill running speed (Vpeak) improved by 7.5 � 4.5%. No changes were observed in HRV indices after BTP, but after ITP, these indices increased significantly (HFP: 1.9%, P 5 0.026; TP: 1.7%, P 5 0.007)…
