Can Exercise Ameliorate Immunosenescence and Thereby Reduce Relapse in Head and Neck Cancer Patients

Through the implementation of this three-year project, investigators expect to find a safe and effective exercise prescription for patients with oral cancer after surgery. The findings will encourage and promise and add further support to the concept that exercise prescription is worth implementation as part of care for the patients with head and neck cancer.

The Effects of High-Intensity Interval Training on Gait, Balance, and Cognitive Functions in Individuals With Multiple Sclerosis

This study aims to comparatively investigate the effects of low-volume High-Intensity Interval Training (HIIT) versus Moderate-Intensity Continuous Training (MICT) on gait, balance, cognitive functions, and neurovascular biomarkers (BDNF, VEGF) in individuals with Multiple Sclerosis (MS). This randomized controlled trial will be conducted at Hacettepe University, Faculty of Physical Therapy and Rehabilitation.

Women With Previous GDM and the Effects of HIIT.

The goal of this clinical trial is to investigate if women with previous gestational diabetes (pGDM) are characterized with unique metabolic and molecular alterations compared to women without pGDM. Furthermore if 8 weeks of high-intensity interval training (HIIT) can improve these alterations. The main questions we aim to answer are: 1. Women with pGDM have metabolic abnormalities compared with women without pGDM, and that these metabolic abnormalities are explained by unique molecular abnormalities in skeletal muscle and adipose tissue. 2. Eight weeks of HIIT combining rowing and cycling can markedly improve these metabolic abnormalities in women with pGDM and these improvements are explained by beneficial cellular and molecular changes in skeletal muscle and adipose tissue. Researchers will compare 20 women with pGDM to 20 glucosetolerant without pGDM, who are matched on age, BMI and times since last pregnancy. Participants will undergo a screening visit and examinations on two separate days before (day 1 and day 2) and two separate days after (day 3 and day 4) 8-weeks of HIIT, in all cases after an overnight fast (≥ 12 h). Day 1 and day 3 will include assessment of body composition and VO2max. On day 2 and day 4, the insulin sensitivity, substrate metabolism, and β-cell function of the participants will be examined by a Botnia-clamp combined by indirect calorimetry. Skeletal muscle biopsies from m. vastus lateralis and subcutaneous abdominal adipose tissue biopsies are taken in the basal and insulin-stimulated states of each clamp.

Effects of HIIT vs. TRE on Type 2 Diabetes Risk

The primary aim of this randomized controlled trial is to examine the effects of a 4-week high-intensity interval training (HIIT) and time-restricted eating (TRE) intervention on cardiometabolic biomarkers in adolescents and young adults.

HIIT Effects on Cardiometabolic Health

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.
