NCT ID: NCT04815460 Completed - Healthy Clinical Trials

Aerobic Interval and Moderate Continuous Exercise Training on Ventricular Functions

Start date: July 1, 2016
Phase: N/A
Study type: Interventional

Hypoxic exposure increases right ventricular (RV) afterload by triggering pulmonary hypertension, with consequent effects on the structure and function of the RV. Improved myocardial contractility is a critical circulatory adaptation to exercise training. However, the types of exercise that enhance right cardiac mechanics during hypoxic stress have not yet been identified. This study investigated how high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) influence right cardiac mechanics during hypoxic exercise (HE).

NCT ID: NCT04733287 Recruiting - Aging Clinical Trials

Heat Therapy and Muscle Function Study

Start date: April 1, 2021
Phase: N/A
Study type: Interventional

Exercise tolerance decreases with age and a sedentary lifestyle. Muscle critical power (CP), is a sensitive measure of exercise tolerance that is more even more relevant to and predictive of endurance performance than VO2max. While recent evidence indicates that CP and muscle function decrease with aging, the cause of this decrease in CP and the best way to mitigate the decrease in CP are unknown. This study will: 1. Measure knee extensor CP in young and old individuals and determine the extent to which changes in muscle oxygen delivery (e.g. resistance artery function, maximum exercise blood flow), muscle mass and composition (e.g. whole-muscle size, muscle fiber cross-sectional area) and mitochondrial oxygen consumption (e.g. maximal coupled respiration of permeabilized fibers biopsied from the knee extensors) contribute to the decrease in CP with age. 2. Examine the effectiveness of two different therapies (1. High Intensity Interval Training, HIIT and 2. Muscle Heat Therapy) at improving muscle function and critical power in young and older adults. 3. Examine the impact of muscle disuse (2 weeks of leg immobilization), a potential contributor to the decrease in muscle function with aging, on muscle function and critical power and determine if heat therapy is an effective means of minimizing the impact of disuse on muscle function and critical power.

NCT ID: NCT04664101 Completed - Covid19 Clinical Trials

REmotely Monitored, Mobile Health-Supported High Intensity Interval Training After COVID-19 Critical Illness (REMM-HIIT-COVID-19)

REMMHIIT-COVID
Start date: March 2, 2022
Phase: N/A
Study type: Interventional

REmotely Monitored, Mobile Health-Supported High Intensity Interval Training after COVID-19 critical illness (REMM-HIIT-COVID-19)

NCT ID: NCT04342390 Completed - Insulin Resistance Clinical Trials

Effects of High-Intensity Interval Training Exercise in Adolescents With Hepatosteatosis

Start date: April 2, 2021
Phase: N/A
Study type: Interventional

This is a research study about how short-term exercise intervention affects adolescents with a disease called non-alcoholic fatty liver disease (NAFLD).

NCT ID: NCT04277091 Completed - Clinical trials for High-Intensity Interval Training

Upper-body High-intensity Interval Training and Mixed Meal Responses

Start date: October 21, 2019
Phase: N/A
Study type: Interventional

Cycling and running-based high-intensity interval training are well-established to improve a variety of health outcomes. However, the efficacy of upper-body high-intensity interval training, vital for individuals with lower-body impairments, has yet to be well-characterized. The purpose of this study is to compare the effect of a single bout of upper-body high-intensity interval exercise (HIIE) in comparison to traditional moderate-intensity continuous exercise (MICE) on the blood response (e.g. glucose, insulin, fats) following a meal. This study is recruiting able-bodied adults (aged 18-65 years). Participants will need to attend the laboratory at the University of Bath for two preliminary sessions, and three main study trials.

NCT ID: NCT04084808 Completed - Clinical trials for Cognitive Performance

Maple Products and Cognitive Performance During High Intensity Intermittent Exercise (HIIE)

Start date: August 8, 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to compare the cognitive performance following the ingestion of carbohydrate solutions containing either maple syrup, maple sap, corn syrup, a commercial sport drink or water.

NCT ID: NCT04084535 Completed - Exercise Training Clinical Trials

Effects of High Intensity Interval Training (HIIT) vs. Inspiratory Muscle Training on the Recovery After a Maximal Apnea.

(HIIT)
Start date: September 16, 2019
Phase: N/A
Study type: Interventional

The aim of this randomized cross-over controlled study was to assess the effects of an 4-week exercise program on the recovery capacity after a voluntary maximal apnea. Participants will be randomly allocated to receive either a high intensity interval training (HIIT), or an inspiratory muscle training (IMT) using an inspiratory resistance device.

NCT ID: NCT04033523 Completed - Heart Failure Clinical Trials

High-Intensity Interval Training Recuperates Capacity of Endogenous Thrombin Generation in Patients With Heart Failure

Start date: July 2, 2013
Phase: N/A
Study type: Interventional

Consumptive coagulopathy is associated with increased mortality in patients with heart failure (HF). Physical activity influences the risk of major vascular thrombotic events. This study investigates how high-intensity interval training (HIIT) affects the capacity of endogenous thrombin generation (TG) by modulating circulatory procoagulant microparticles (MPs) in HF patients. Thirty-eight HF patients and 38 age- and gender-matched normal counterparts (NC) were recruited into this study. The HF group performed HIIT (3-min intervals at 40% and 80%VO2peak) on a bicycle ergometer for 30 min/day, 3 days/week for 12 weeks, whereas the NC group did not receive any form of intervention. Plasma TG kinetics, procoagulant MPs, coagulation-related factors, and oxidative stress/proinflammatory status were analyzed. The results demonstrated that the HF group exhibited (i) less endogenous thrombin potential (ETP) and TG rate, (ii) lower concentration/activity of tissue factor (TF) and counts of TF-rich MPs derived from blood cells, and (iiii) higher vascular endothelial shedding and plasma myeloperoxidase and interleukin-6 concentrations, compared to the NC group did. However, HIIT elevated plasma ETP and TG rate, as well as, TF concentration/activity and blood cell-derived procoagulant MP levels in the HF patients. Moreover, the exercise regimen also decreased vascular endothelial shedding and plasma myeloperoxidase and interleukin-6 concentrations in patients with HF. Hence, we conclude that HF reduces the capacity of endogenous TG in plasma, which is associated with decreased (or consumed) circulatory procoagulant MP levels. However, HIIT alleviates HF-declined endogenous TG capacity and vascular endothelial damage through recuperating TF-related coagulation activity and suppressing oxidative stress/proinflammatory status.

NCT ID: NCT03759951 Completed - Body Composition Clinical Trials

Hybrid Exercise Training for Health, Performance and Well-Being (DoIT II)

Start date: July 1, 2019
Phase: N/A
Study type: Interventional

Observing a lack of research investigating the chronic physiological and psychological responses to this type of exercise training the aim of this study is to investigate the optimal training configurations of DoIT to produce positive effects on health, performance and quality of life markers in sedentary overweight or obese adults aged 30-55 years. The DoIT program will be performed in a small-group setting indoor or outdoor implementing a progressive manner for 12 months and using bodyweight exercises with alternative modes.

NCT ID: NCT03700671 Completed - Clinical trials for High Intensity Interval Training

High Intensity Interval Training Versus Circuit Training

Start date: May 11, 2016
Phase: N/A
Study type: Interventional

High intensity interval training (HIIT) and circuit training (CT) are popular methods of exercise, eliciting improvements in cardiorespiratory fitness (CRF). However direct comparisons of these two training methods are limited.
