Filter by:Studies on resistance training (RT) associated with blood flow restriction (BFR) is an alternative method of gaining strength and hypertrophy muscle. However, there is a gap correlated to autonomic repercussion of BFR and performance. Thus, it becomes relevant to investigate this type of training in post-exercise. Objective: investigate and compare autonomic and performance responses of 6 weeks of eccentric RT with different intensities associated or not to BFR in healthy youngsters. Method: This is a randomized clinical trial including 60 healthy men aged 18-35 years, divided into four groups according to exercise intensity and BFR: 80% without BFR, 40% without BFR, 80% with BFR and 40% with BFR. Exercise intensity will be determined by the peak of excentric torque on the isokinetic dynamometry method and by the BFR, as being 40% of the intensity required for the complete examination of the blood flow evaluated by Doppler. Participants will do an eccentric femoral quadriceps muscle exercise session on the isokinetic dynamometer according to the previously randomized group. For recovery analyzes, it will be used: the root-mean-square of the successive normal sinus RR interval difference (rMSSD); high frequency (HF) ms²; HF(nu) and the standard deviation of instantaneous beat-to-beat interval variability (SD1). For performance, it will be used the single leg hop test. For data analysis of the population profile, the descriptive statistical method will be used and the results will be presented with values of means, standard deviations, median and confidence interval. Initially, participants from all study groups will be dichotomized at each performance outcome (muscle strength test on the isokinetic dynamometer and vertical jump test) as "improvement" or "without improvement" in order to demonstrate the behavior of the responses obtained during the training, that is, whether the individual responded to the RT or not. It is worth mentioning that this qualitative analysis will be performed considering the data obtained from the initial, intermediate and final evaluation. The dichotomization of the results of the functional tests will be performed by the typical error of the sample measurement for each test. It will be considered as "improvement" if the participant presents gains in tests above the typical error of the measure. The values obtained from the initial, intermediate and final evaluation will be analyzed independently. Subsequently, the weekly average of the vagal indices (rMSSD, HF and SD1) will be performed in the baseline moment and after 6 weeks of RT moment of each study group. In the sequence, the performance parameters will be correlated with the autonomic parameters in the respective groups. Pearson or Spearman correlation test will be used according to the normality of the data. The level of significance will be p <0.05 for all tests. The statistical program SPSS (Statistical Package for the Social Sciences) will be used for the analyzes.
While "conditioning" by exercise training has been widely evaluated, the available literature on "passive deconditioning" (i.e. forced deconditioning) is predominately limited to studies with or with almost complete mechanical and/or metabolic immobilization/sedation of the respective functional system (e.g. paralysis, bedriddenness). Vice versa, the effects of moderately long interruptions of dedicated types of exercise while maintaining everyday activity are rarely addressed. However, this topic is of high relevance, e.g. considering that breaks of health-related exercise programs due to increased family/occupational stress, vacation or temporary orthopedic limitation are rather frequent in everyday life. In the present project we aimed to determine the effects of 3 months of physical deconditioning due to COVID-19 induced lockdown after 13 month of high intensity endurance and resistance exercise in early postmenopausal women on parameters related to health and physical fitness.
Total knee replacements are a common orthopaedic procedure undertaken at Blackpool Victoria Hospital. Following surgery patients are routinely seen by Physiotherapists who prescribe exercises to improve the range of movement and strength of the knee joint, thus aiding recovery. One of the key exercises prescribed involves the bending and straightening of the knee to improve range of movement. At this early stage of rehabilitation , due to weakness in the knee joint, reducing any resistance to this motion is beneficial. The Orthoglide device is designed to aid the patient in performing this movement by reducing the friction/resistance caused by the heel sliding against the bed. Currently this is achieved using a 'slider board' and placing a rolled up piece of fabric under the patients heel. The aim of this study is to investigate whether or not issuing an Orthoglide device to patients following total knee replacements improves functional outcomes reported by the patient at 6 weeks and 12 weeks post-surgery. Participants will be assigned to either receive an Orthoglide device and standard Physiotherapy or standard Physiotherapy alone. A series of patient reported outcome measures will be taken pre-surgery, 6 weeks post surgery and 12 weeks post surgery and the results compared.
Sixty girls participated in this study and their main complaints were pain and cramping during menstruation. They were divided randomly into two equal groups.
Patients with COPD are often unable to sustain a sufficient workload during exercise. The use of external strategies to improve exercise tolerance, such as non-invasive ventilation (NIV) and high-flow nasal therapy (HFNT) have been used. The objective was to evaluate and compare the acute effects of HFNT and NIV during exercise on cardiorespiratory parameters, dyspnea, exercise tolerance and comfort in patients with moderate to severe COPD.
In December 2019, the new coronavirus pneumonia (COVID-19) exploded in Wuhan (Hubei, China) and spread rapidly from one city to the whole world. This virus resulted in a total of 1679720 confirmed cases and 101734 deaths worldwide. All countries in the world are taking some precautions to prevent the spread of this epidemic disease, which World Health Organization (WHO) declared as "epidemic". Staying home and social isolation are among these precautions. For this purpose, it began to implement the curfew for all individuals on 10 March 2020, Turkey. However, not leaving the house and social isolation bring about the limitation of physical activity. Physical activity (PA) is defined as anybody's movement produced by WHO by contraction of skeletal muscles. Studies investigating the relationship between social isolation and health behavior report consistent findings. Individuals with smaller social networks report less healthy diets, excessive alcohol consumption, and less physical activity. Traditional exercises; It takes place outdoors in gyms or rehabilitation centers. However, with the increase in the time we spent at home due to the coronavirus (COVID-19) epidemic, technologies have been used as an alternative method. Home-based exercise programs are also a viable solution to prevent various health problems that may be encountered in this direction. The decrease in physical performance is associated with loss of muscle strength, low quality of life, emotionalization, comorbidity, premature death, and increased health costs. When today's conditions are evaluated, technology-supported education programs are effective in increasing motivation for physical support. The purpose of this study; To prevent the spread of the COVID-19 outbreak, to evaluate the physical activity levels of individuals between the ages of 18-40 who have social isolation due to the measures taken in our country and to investigate the effectiveness of their video-based exercises.
Due to the aging of the earth's population in the coming years, strategies for preventing falls in the elderly are of increasing research interest. Injuries due to falls have a direct impact on the quality of life of the elderly and are associated with very high costs for the healthcare system. However, few organized fall prevention interventions have been implemented in Greece, unlike other EU countries. The systematic recording of falls, the information and education of older people about injury prevention and the participation of older people in organized fall coping strategies in Greece are almost non-existent. Group exercise programs have proven to be effective in reducing falls. The OTAGO exercise program has shown that it can effectively reduce the number of falls in the elderly by up to 54%. However, its widespread implementation by a government agency in Greece such as the Elderly Day Care Centers (EDCC) has not yet been possible.
Resistance training (RT) is one of the most important stimuli for muscle hypertrophy and it plays an important role on weight loss and fatty acid oxidation increase. RT affects anabolic pathways but the differences among various training techniques has been till now were poorly investigated. The aim of this study was to compare the effect of two different intensity of training, high-intensity interval resistance training (HIIRT) and traditional resistance training (TRT), on muscle signalling pathway.
Background: Obesity is one of the most important health problems worldwide, several factors related to lifestyle as physical inactivity and unbalanced diets increase their development. This condition is characterized by low-chronic inflammation by excess of adipose tissue. The apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) protein is part of NLRP3 inflammasome, a complex related to inflammation and metabolic alterations. Purpose: The aim of this study was to evaluate the effect of physical exercise program on ASC gene expression and inflammatory markers in obese adults. Methods: 37 obese individuals were randomized to exercise-diet group or diet-group during a 4-month follow-up period. The dietary evaluation was analyzed by Nutritionist Pro software. Body composition was evaluated by bioimpedance (InBody 370). All biochemical determinations were analyzed by dry chemistry (Vitros 350). ASC messenger ribonucleic acid (mRNA) expression was performed by real-time polymerase chain reaction (PCR) using Taqman probes and by the 2-ΔΔcq quantification method. Cytokine levels was performed using the Bio-PlexPro™ HumanTh17Cytokine Assays (MagPix) panel. Statistical analysis was performed with Statistical Package for the Social Sciences (SPSS) v.22 software.
