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.
The aim of this study is to find out the effect of multimodal high intensity interval training on speed, agility and performance among cricket player.
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.
High-intensity interval training has been beneficial in many sports and significantly enhanced the results of physical training. Consequently, it has progressively been implemented among the football players. A Cluster Set (CS) is a set that has been broken up into smaller blocks of repeats with the inclusion of brief intra-set breaks or a reorganization of the breaks between repetitions. The initial assumption is that this design would offer a superior rise in exercise quality with the potential to maintain or enhance performance and enable larger loads, leading to stronger performance adaptations. The objective of the study is to compare the effects of high intensity interval training and cluster training on speed, explosive strength and functional performance in football players.
The study is randomized and single-blinded. Ethical approval is taken from ethical committee of Riphah Internatinal University, Lahore. Participants who meet the inclusion criteria will be enrolled and allocated in group A & B through sealed envelope method by Non-probability Convenient random sampling technique. Subjects in Group A will receive tabata training. Group B will receive plyometric training.
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.
Local muscle endurance (LME) is the ability of a muscle(s) to resist fatigue and is needed for daily activities of life such as climbing stairs, lifting/moving objects, and in sport contexts like rock climbing, mixed martial arts, cross-fit, kayaking and canoeing. Therefore, the investigators want learn how to improve LME and understand what in human bodies changes during exercise training to cause these changes. The investigators know that lifting weights improves muscle strength which is believed to improve LME. Specifically lifting less heavy weights (LLRET) for more repetitions leads to greater gains in LME opposed to heavier weights for fewer repetitions. Therefore, lifting less heavy weights likely causes greater changes in our muscles than lifting heavier weights that cause improvements in LME. Aerobic exercise preformed at high intensities in an interval format (HIIT) may also help improve LME by increasing our muscle's ability to produce energy during exercise. Therefore, the investigators want to see which of LLRET or HIIT leads to greater improvements in LME.
The primary aim of this randomized clinical trial is to compare the effects of three different HIIT protocols and a control group on cardiometabolic health in young adults with obesity. Participants will be randomly assigned to one of the following three groups, with each having varying work-to-rest ratios: 1) HIIT-A, 2) HIIT-B, 3) HIIT-C, and 4) control group. HIIT-A, HIIT-B, and HIIT-C groups will participate in six sessions of a running based HIIT program over a 2-week training period. Pre-clinical markers of cardiovascular disease, blood lipids and fasting glucose will be measured at the following three time points: baseline, post-intervention, and 2 weeks after the training cessation (i.e., measure for detraining effect). All measurements will be performed three days before the training program and three days after the intervention to avoid the effect of the last training session. Afterwards, the detraining test will be measured 2 weeks post intervention.
