Filter by:the effects of high-intensity interval training on myocardial function will be studied in a group of patients under medical treatment for the components of metabolic syndrome.
One hundred and forty-one male and female participants aged 18-59 years were randomly divided into 4 groups: 1) control group: neither received exercise program nor supplement but received placebo capsule for 8 weeks 2) experiment-1: received Triphala capsule at 1,000 mg/day, before breakfast for 500 mg and before dinner for 500 mg, for consecutive 5 days/week for 8 weeks 3) experiment-2: received leg cycling exercise program in the form of high-intensity interval training (HIIT) for 28 min/day, 3 days/week for 8 weeks and 4) experiment-3: received both Triphala capsule and HIIT in the similar extent to the experiment-1 and experiment-2 groups for 8 weeks. Immune system function and oxidative stress including blood interferon-gamma (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha), malondialdehyde (MDA), and protein carbonyls levels were analyzed. In addition, blood alanine aminotransferase (ALT) enzyme and creatinine levels were also analyzed for determining liver and kidney toxicity, particularly in the Triphala supplementation and combined Triphala supplementation and HIIT groups.
Aerobic capacity is critical for many athletes, especially for endurance athletes. Althgough several training methods are implemented by coaches to improve endurance performance, recovery following acute endurance training is not adequately studied. However, such information is crucial for coaches to effectively design the most favorable training program, to avoid muscle injuries and overtraining, and ultimately to improve performance of their athletes. This study aims to examine the acute effect of different continuous and HIIT training protocols on indices of metabolism, EIMD, neuromuscular fatigue and performance in middle- and long-distance runners.
The goal of this repeated measures study is to evaluate acute work rate adjustments during high-intensity interval training (HIIT) in a hot and temperate environment in healthy and active adults when using target heart rate to prescribe the exercise intensity. The main questions it aims to answer are: - Will HIIT based on target heart rate in a hot environment result in increased cardiovascular (i.e., elevated recovery HR) and thermal strain compared to HIIT in a temperate environment? - Will work rate be lowered to a greater extent during HIIT in a hot environment compared to a temperate environment in order to maintain target heart rate? - Will maximal aerobic capacity (V̇O2max) decrease to a greater extent after HIIT in the heat compared to a temperate environment? Procedures: Participants will complete 5 trials on a cycle ergometer. Trial 1 (Control Visit): Participants (n = 7) will have their maximal heart rate and V̇O2max measured in a temperate environment (~22 °C, 40% RH). Experimental Trials 2-5: The order of the trials will be counterbalanced and randomly assigned to participants. - 15TEMP: Participants will cycle at 70% of their maximum heart rate for 8 minutes as a warm-up, followed by one round of HIIT. The HIIT protocol consists of 4 minutes at 90% of maximum heart rate followed by 3 minutes at 70% of maximum heart rate, totaling 15 minutes, in a temperate environment (~22 °C, 40% RH). After the HIIT session, a graded exercise test will measure V̇O2max. - 15HEAT: Similar to 15TEMP, but participants will perform the HIIT protocol in a hot environment (~35 °C, 40% RH). - 43TEMP: Participants will cycle at 70% of their maximum heart rate for 8 minutes as a warm-up, followed by the HIIT protocol repeated four times (4 minutes at 90% of maximum heart rate and 3 minutes at 70% of maximum heart rate), totaling 43 minutes, in a temperate environment (~22 °C, 40% RH). - 43HEAT: Similar to 43TEMP, but participants will perform the HIIT protocol in a hot environment (~35 °C, 40% RH).
Creatine is an ergogenic aid with positive effects on muscle and performance. The aim of the study was to determine whether there is a difference between the effects of creatine supplementation taken together with Wingate-based HIIT on anaerobic power, leg strength, heart rate variability and body composition. In the study, Wingate-based HIIT program was applied three days a week for six weeks. Anaerobic power (Wingate anaerobic power test), heart rate variability (Polar H10 chest band), leg strength (back and leg dynamometer) and body composition (PlusAvis 333) measurements of the participants were made 1 week before the training program started and the week after the training program ended. Twenty physically active adult men aged 18-30 were voluntarily included for the study. Participants were divided into two groups: Wingate-based HIIT with creatine supplementation (K-HIIT) and Wingate-based HIIT only (HIIT). As a result of the analysis, it was seen that creatine supplementation taken together with wingate-based HIIT had an effect and increased on the anaerobic power parameters, peak power, average power and minimum power values, and leg strength. In addition, it was determined that heart rate variability parameters improved heart rate (HR, beat/min) and low frequency (LF, ms2) values, but did not cause any change in body composition. Comparing and investigating the effects of different HIIT methods on anaerobic power, leg strength, heart rate variability and body composition will increase the generalizability of the study.
The investigators propose to compare the effects of a 12-week load resistance training program to a velocity resistance training program on ultrasound measures of quadriceps muscle quality in a healthy, older adult population. As secondary measures, The investigators propose to compare the effects of these exercise programs on maximal strength, power, and functional movements such as the chair sit-to-stand and gait speed. Further, The investigators will evaluate the impact of each protocol on cognitive function.
Recommended by many professional organizations such as the American College of Sports Medicine (ACSM) and the National Strength and Conditioning Association (NSCA), resistance exercise training improves muscle strength, body composition, performance, functionality and quality of life in healthy young adults. Blood flow restriction (BFR), also known as Kaatsu training, is proposed as a new method to improve muscle strength and muscle hypertrophy in a short time. Although there are studies in the literature in which BFR is applied with low-intensity resistance training, no studies have been found examining the effects of BFR applied with high-intensity resistance training on the neuromuscular adaptations of the quadriceps femoris muscle. Determining whether high-intensity resistance training with BFR is more effective on the quadriceps femoris muscle compared to high-intensity resistance training applied without BFR may provide faster and more effective responses by arranging resistance training protocols in terms of neuromuscular gains. Between 07.03.2022 and 07.06.2022, in the Biruni University Physiotherapy and Rehabilitation Department Application Laboratory, in which 24 healthy young adults between the ages of 18-25 (from 12 BFR, 12 BFR) will be included, exercise training to be applied with and without BFR was determined. Its effects will be compared with electromyographic measurement, single leg squat test, and measurement of late-onset muscle pain (Visual Analog Scale). IBM SPSS 21.0 statistical program will be used for statistical analysis. Whether the variables are suitable for normal distribution will be analyzed with the Shapiro-Wilk test. If the variables show normal distribution, the variation within the group will be analyzed with the paired samples t test, and if it does not show normal distribution, the Wilcoxon Signed rank test will be analyzed. Comparison of groups will be made with independent samples t-test in independent groups if the variables show normal distribution, and with Mann Whitney-U test if they do not show normal distribution. Categorical data distributions will be evaluated with the Chi-square test.
