BACKGROUND: High-intensity eccentric-concentric contractions of the jaw-closing muscles induce muscle soreness, fatigue, and functional impairment of the jaw, resembling the symptoms of myalgia, according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). However, it is claimed that repetition of similar exercises can minimize these detrimental effects. OBJECTIVE: This study aimed to evaluate the response of jaw closing muscles following two series of intense eccentric-concentric exercises of the masticatory muscles in healthy subjects...

PURPOSE: We aimed to determine if yearly repeated exercise training reduces metabolic syndrome (MetS) and the use of medicines to control MetS components. METHODS: Fifty five MetS individuals were randomized into a TRAIN group that underwent two yearly programs of 16-week of high intensity interval training (HIIT) or a non-exercising CONT group. We measured the evolution of all five MetS components, cardiorespiratory fitness (CRF; assessed by VO2PEAK) and medicine use, at baseline (0 months), mid (12 months) and end-point (24 months)...

The aim of the present study was to investigate the effects of high-intensity interval training (HIIT) versus low-intensity continuous training (LICT) on transcriptional levels of neurotrophic factors and oligodendrocyte/microglia cell loss in a cuprizone (CP) induced animal model of demyelination. Male C57BL/6 mice were assigned to six groups: control (C), cuprizone-induced demyelination (CP), interval training (IT), continuous training (CT), IT plus CP (ITCP), and CT plus CP (CTCP). Training programs on the treadmill were performed for four weeks, and then demyelination was induced by feeding mice a diet containing 0...

BACKGROUND/AIMS: Temporary proteinuria post-exercise is common and is caused predominantly by renal haemodynamic alterations. One reason is up-regulation of angiotensin II (Ang II) due to the reducing effect of angiotensin-converting enzyme (ACE) inhibitors. However, another, ignored, reason could be the kininase effect of ACE inhibition. This study investigated how ACE inhibition reduces post-exercise proteinuria: by either Ang II up-regulation inhibition or bradykinin elevation due to kininase activity inhibition...

Evidence from large multicentre exercise intervention trials in heart failure patients, investigating both moderate continuous aerobic training and high intensity interval training, indicates that the 'crème de la crème' exercise programme for this population remains to be found. The 'aerobic/resistance/inspiratory (ARIS) muscle training hypothesis in heart failure' is introduced, suggesting that combined ARIS muscle training may result in maximal exercise pathophysiological and functional benefits in heart failure patients...

PURPOSE: High-intensity interval training (HIIT) may lead to superior cardiometabolic improvements when compared to moderate-intensity continuous training (MICT). However, adherence to HIIT requires examination. The purpose of this pilot study was to examine moderate-to-vigorous physical activity (MVPA) adherence 24 weeks following a brief counselling intervention combined with either HIIT or MICT. METHODS: Individuals at high risk of type 2 diabetes (T2D) were randomized to HIIT (n = 15) or MICT (n = 17) and completed 10 exercise sessions accompanied by a brief 10-minute counselling intervention over a 2-week period...

OBJECTIVES: While exercise significantly reduces craving for cigarettes, the effect of exercise on self-initiation of quit attempts is less known. Therefore, this randomized pilot study explored the effect of starting an exercise program on self-initiated quit attempts, and also the feasibility and acceptability of a novel exercise intervention, high-intensity interval training (HIIT), as compared with a more traditional continuous aerobic (CA) exercise intervention. METHODS: Participants smoked (≥5 cigarettes/d), were aged 18 to 40 years, and wanted to increase their exercise...

Background: Knee osteoarthritis (OA) patients often suffer joint pain and stiffness, which contributes to negative changes in body composition, strength, physical performance (function), physical activity and health-related quality of life. To reduce these symptoms and side effects of knee OA, moderate-intensity continuous training (MICT) cycling is often recommended. While resistance training is considered the optimal form of training to improve sarcopenic outcomes, it imposes higher joint loads and requires supervision, either initially or continuously by trained exercise professionals...

BACKGROUND: Mechanical efficiency (ME) refers to the ability of an individual to transfer energy consumed by external work. A decreased ME, could represent an increased energy cost during exercise and may, therefore, be limited in terms of physical activity. This study aimed to compare the influence of two different exercise protocols: moderate continuous training (MCT) versus high intensity interval training (HIIT), as part of a cardiac rehabilitation program on ME values among coronary patients...

Gestational diabetes mellitus (GDM) occurs in 2-9% of all pregnancies. Evidence suggests that the use of insulin in treating hyperglycemia in GDM patients reduces the risk of perinatal morbidity. Pregnancy is an exciting time in a woman's life. However, once patient is diagnosed with GDM, she will be managed more intensively. GDM is managed using diet and exercise but one in six women with GDM requires insulin. A 35-year-old woman at the 14th gestational week of her tenth pregnancy was seen for routine prenatal care...
