Cancer has emerged as a prominent cause of mortality in the 21st century, with breast cancer (BC) being the most diagnosed malignancy. Multidisciplinary cancer management has improved survival chances, but side effects and long-term consequences of treatments have significant implications for cancer survivors' health-related quality of life. Exercise is increasingly considered and used in cancer treatment and follow-up. However, studies demonstrating the biological mechanisms underlying the anticarcinogenic effects (ACE) of exercise are insufficient to justify the most appropriate physical activity for different clinical scenarios. Achieving scientific excellence in understanding the ACE of exercise in cancer management is critical to optimize treatment and enhance patients' quality of life.
NCT07188389
This study aims to examine the effects of acute aerobic exercise and cardiorespiratory fitness on cellular metabolism of CD8+ T cells and regulatory T cells (Tregs) found in the peripheral blood of humans. In addition, the study will investigate whether the effects of exercise differ based on exercise intensity, as well as whether the effects of exercise and fitness differ between subpopulations of CD8+ T cells and Tregs. Finally, the study aims to examine whether exercise- and fitness-induced changes in cell metabolism relate to changes in cell function.
NCT06645119
The goal of this clinical trial is to investigate the effects of protein ingestion post-exercise on bone turnover markers. The main questions it aims to answer is: Does protein ingestion independently influence the bone metabolic response to exercise in endurance runners? We will compare dietary protein to a placebo (water) to detect changes in bone turnover markers. Participants will: In a within-subject design, participants will perform an exhaustive run and take either protein or placebo immediately post-exercise. Track physical activity and diet before each arm of the intervention and during the washout period.
NCT05298202
The purpose of this study is to examine the human thermoregulatory impact of applying a commercially available capsaicin gel to the skin prior to moderate intensity walking under heated conditions. Experimental Visits will consist of 30 min of treadmill walking at a moderate pace (3.5 mph, 5% grade) under hot conditions (38°C, 60%RH) and will be randomized and counterbalanced for capsaicin gel or a hypoallergenic gel (control) application. Gels will be applied to areas commonly exposed during outdoor activity in warm conditions (shoulder to wrist, mid thigh to ankle). Accordingly, participants will wear shorts and a tank top shirt during exercise. Core temperature, skin temperature, galvanic skin response, laser doppler blood flow, and heart rate will be continuously recorded throughout the exercise bout via an integrated analog to digital converter. Sweat will be collected during exercise using commercially available absorbent patches. Thermal sensation will be assessed throughout exercise via the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) thermal sensation likert scale (cold to hot). Lastly, nude body weight will be recorded pre and post exercise for sweat rate determination. The capsaicin and control trials will be separated by a 7-14 day washout period
NCT05389033
Endurance athletes will be invited to participate in the following study. Subjects will visit the laboratory on three occasions, each time following an overnight fast. Briefly, following an initial assessment and familiarisation, participants will be required to complete an endurance bout of cycling exercise in hot environmental conditions before and after 4 weeks of supplementing with a probiotic or placebo. During the exercise bouts, breath samples will be collected for measurements of whole-body metabolism, blood samples will be collected to assess serum metabolites and markers of gastrointestinal (GI) damage, and subjective measures of effort and symptoms of GI thermal distress will be collected. Before and after each exercise bout, participants will be required to provide a faecal sample for analysis of the microbiome and GI inflammation
