Home-based inspiratory muscle training for management of older patients with heart failure with preserved ejection fraction: does baseline inspirator…
2019
Background:Heart failure with preserved ejection fraction is a clinical syndrome characterised by reduced exercise capacity. Some evidence has shown that a simple and home-based programme of inspiratory muscle training offers promising results in terms of aerobic capacity improvement in patients with heart failure with preserved ejection fraction. This study aimed to investigate whether the baseline inspiratory muscle function predicts the changes in aerobic capacity (measured as peak oxygen uptake; peak VO2) after a 12-week home-based programme of inspiratory muscle training in patients with heart failure with preserved ejection fraction.Methods:A total of 45 stable symptomatic patients wi…
Alveolar gas exchange and tissue deoxygenation during exercise in type 1 diabetes patients and healthy controls.
2012
We used near-infrared spectroscopy to investigate whether leg and arm skeletal muscle and cerebral deoxygenation differ during incremental cycling exercise in men with type 1 diabetes (T1D, n=10, mean±SD age 33±7 years) and healthy control men (matched by age, anthrometry, and self-reported physical activity, CON, n=10, 32±7 years) to seek an explanation for lower aerobic capacity (˙VO2peak) often reported in T1D. T1D had lower ˙VO2peak (35±4mlkg(-1)min(-1) vs. 43±8mlkg(-1)min(-1), P0.01) and peak work rate (219±33W vs. 290±44W, P0.001) than CON. Leg muscle deoxygenation (↑ [deoxyhemoglobin]; ↓ tissue saturation index) was greater in T1D than CON at a given absolute submaximal work rate, bu…
Near-normal aerobic capacity in long-term survivors after lung transplantation
2021
The clinical course of lung transplantation (LT) is diverse: some patients present chronic lung allograft dysfunction (CLAD) and progressive decline in pulmonary function, but others maintain normal spirometric values and active lives. Objectives The aim of this study was to elucidate whether long-term LT survivors with normal spirometry achieve normal exercise capacity, and to identify predictive factors of exercise capacity. Methods This was a cross-sectional multicentre study, where bilateral LT recipients who survived at least 10 years after LT, with normal spirometry, no diagnosis of CLAD and modified Medical Research Council dyspnoea degree ≤2 underwent cardiopulmonary exercise testin…
Ketogenic diet, physical activity, and hypertension—a narrative review
2021
Several studies link cardiovascular diseases (CVD) with unhealthy lifestyles (unhealthy dietary habits, alcohol consumption, smoking, and low levels of physical activity). Therefore, the strong need for CVD prevention may be pursued through an improved control of CVD risk factors (impaired lipid and glycemic profiles, high blood pressure, and obesity), which is achievable through an overall intervention aimed to favor a healthy lifestyle. Focusing on diet, different recommendations emphasize the need to increase or avoid consumption of entire classes of food, with only partly known and only partly foreseeable consequences on the overall level of health. In recent years, the ketogenic diet (…
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 ‘…
Kehitysvammaisten aikuisten kestävyyskunnon taso ja muutos ikääntyessä : kahden kävelytestin vertaaminen
2015
Eveliina Keinonen (2015). Kehitysvammaisten aikuisten kestävyyskunnon taso ja muutos ikääntyessä: Kahden kävelytestin vertaaminen. Liikuntakasvatuksen laitos, Jyväskylän yli-opisto, liikuntapedagogiikan pro gradu –tutkielma, 66 s., 3 liitettä. Tutkimuksen tavoitteena oli tarkastella keski-ikäisten kehitysvammaisten naisten ja miesten kestävyyskunnon tasoa vammattomaan väestöön sekä Suomessa yleisesti käytössä oleviin terveysliikunnan suosituksiin verrattuna. Tarkastelun kohteena oli myös kehitysvammaisten kestävyyskunnossa esiintyvät muutokset seitsemän vuoden aikana. Lisäksi tutkimus pyrki selvittämään onko samanaikaisesti suoritettujen UKK-instituutin 2 kilometrin kävelytestin ja Rockport…

Effects of added endurance or strength training on cardiovascular and neuromuscular performance of conscripts during the 8-week basic training period
2010
The present series of studies investigated changes in Finnish conscripts’ body composition, aerobic fitness and muscle endurance profiles during the last three decades. A second aim was to examine the effects of added endurance (ET) or strength training (ST) on cardiovascular and neuromuscular performance as well as hormonal responses of conscripts during an 8-week basic training (BT) period when compared to the current standardized (NT) programme. The third aim was to study the effects of these three different training programmes on a novel 3K combat running performance test. The present results showed that aerobic fitness and muscle endurance of 20 year old men in Finland has decreased a…
Hill Runner's Physiology, Performance and Nutrition: A Descriptive Study.
2021
Objectives: The aim of this descriptive study was to characterise anthropometric variables, aerobic capacity, running performance and energy intake and expenditure of hill runners in free-living conditions, and to investigate the relationship between age, anthropometric variables, aerobic capacity and running performance.Methods: Twenty-eight hill runners participated in this study (17 males and 11 females; aged 18–65 years). Body fat percentage estimate, sum of eight skinfolds (triceps, subscapular, biceps, iliac crest, supraspinale, abdominal, front thigh and medial calf) and maximal oxygen capacity (VO2max) were assessed in a laboratory setting. Participants also completed a timed hill r…
Effect of training on aerobic capacity of female athletes differing in muscle fibre composition
1983
Abstract The effects of endurance training were studied in two groups of female cross‐country skiers who differed in muscle fibre composition. The ST‐group (n = 10) had 56–76% slow twitch (ST) muscle fibres and the FT‐group (n= 10) 40–55% ST fibres in the m. vastus lateralis. During a four‐month period, the subjects trained on the average 81 km per week. The intensive training (heart rate 0–15 beats per min below maximum) averaged 8.5 km per week. The differences in training between the two groups were not significant. The ST‐group significantly increased their cycling maximum oxygen uptake (C max, 4.6%, P <0.01) and the anaerobic threshold (AT, 2.8%, P <0.01) during the training period whe…
