Known as "Thai boxing," Muay Thai utilizes a combination of upper limb strikes (such as punches and elbow strikes) as well as lower limb strikes (such as kicks and knee strikes), and is thus referred to as the "art of eight limbs." It is practiced worldwide and is a prominent discipline in many mixed martial arts (MMA) training camps. In this sport, training load control involves monitoring and adjusting the quantity and intensity of training according to each athlete's capacity. In the context of combat sports, such as Muay Thai, heart rate variability (HRV) and assessment of body composition by bioelectrical impedance analysis can be used as tools to evaluate training responses. Additionally, HRV can also serve as a tool for assessing recovery after training or competition. If HRV does not return to baseline after training or competition, it may be a sign that the athlete is not fully recovered and may need more time to recuperate before returning to training or competition. Due to the absence of studies in the literature that have assessed a possible association between HRV and dehydration and rehydration processes in amateur Muay Thai athletes, it becomes essential to evaluate this correlation. Given the growing interest in practicing Muay Thai in gyms, assessing the sympathetic-vagal balance, body composition, and performance of these athletes becomes of utmost importance. Therefore, the aim of this study is to investigate the relationship between dehydration indicators, HRV parameters, and performance in the frequency speed kick test (FSKT). Participants will be assessed before and after an eight-week training program, conducted three times a week. Assessments will include resting HRV measurement and FSKT; in addition, bioimpedance will be used to estimate the body composition of participants pre- and post-training. It is expected that the results will reveal changes in HRV, performance, and body composition of the athletes after training.
Approximately 60% of males and 40% of females do not meet current fluid intake recommendations, which is associated with adverse health consequences such as obesity, diabetes, and chronic kidney disease. Newer technologies have been designed to promote fluid intake. "Smart Water Bottles" use mHealth technology to capture fluid intake behaviors automatically and provide cues to encourage fluid consumption. Studies using Smart Water Bottles have helped some individuals increase fluid intake to help reduce kidney stone formation. However, limited research has assessed the efficacy of this technology on improving fluid intake in college students. College is a time with the potential to form healthy habits that carry into adulthood. Previous work has also identified daily changes in morning urine color, thirst perception, and body mass, as simple, inexpensive indicators of daily fluctuations in water balance. Tracking changes in these metrics has the potential to provide participants with evidence of adequate or inadequate fluid consumption. Thus, the combination of prompting from a smart water bottle, as well as daily self-monitoring changes in hydration status, may encourage college students to increase daily fluid consumption.
The primary objective of this study is to analyze smart phone-based Transdermal Optical Imaging (TOI) features to develop a model that can discern hydration status, including: 1) at various timepoints throughout a 24-hour period in healthy adults from the general population (GENPOP), and 2) before and after a team coach-led training session in athletes competing in a sport (ATHLETE). TOI data will be collected alongside standard reference measures of hydration status. In this study each subject will serve as their own control.
During the Covid-19 pandemic, admission patterns for infections other than Covid-19 have changed dramatically among children worldwide. Particularly admissions due to respiratory infections and later invasive streptococcal infections have been well documented. However, few studies have compared rates af gastro-intestinal infections during the pandemic with the previous years. This study aims to compare the number and characteristics of children hospitalized with gastrointestinal infections before the COVID-19 pandemic, to the first strict lockdown in 2020 and to the second, less strict lockdown in 2021. A retrospective review of medical records will be performed, of patients aged 1 month to 5 years admitted with gastroenteritis at the pediatric department at Slagelse Hospital in Denmark over a period from 2017 to 2021.
This is a prospective, randomized, controlled, blinded, crossover study to evaluate the effects of an oral hydration solution.
The low fluid intake in combination with a high intake of sugar-sweetened beverages (SSB) by children is a significant concern among public health professionals. Therefore reformulation of existing commercially available beverages has been suggested as one of the strategies to change SSB beverage behaviors of children. It has been suggested that lack of flavor in plain water is one of the factors of low water intake in children. Therefore, the addition of a flavor to a low-carbohydrate beverage might increase and facilitate the voluntary fluid intake in children, and result in more effective rehydration during and after exercise. The present study aims to examine if a lower sugar flavored water will improve voluntary hydration in children that perform multiple exercise bouts within a period of 3 hours.
The electrolyte test products are composed of powder and provided in individual stick packs with 5 vitamins including Vitamins B3, B5, B6, B12 and Vitamin C. The products are gluten-, soy-, and dairy-free, and provide electrolytes at concentrations well below the daily value (DV). The DV tells us how much a particular nutrient in a serving of a food product contributes to a daily diet, based on a standard 2000 calorie diet. Despite what the name suggests, this product is taken orally, not intravenously. These packets contain a small percentage of the needed total daily electrolytes but adequate amounts to replace lost electrolytes as a result of physical activity. The products will be consumed following a 90-minute bout of cycling exercise at a moderate intensity of 70-80% max heart rate, at 30-32°C (86-89°F) and 50 ± 5% relative humidity. This same exercise duration and room temperature has been used in a recent study, which also utilized the same body temperature monitoring device as proposed in the present study. The purpose of the exercise bout is to simulate what many individuals are exposed to when exercising in the heat and to moderately dehydrate subjects, as would be the case during a moderate run or cycling event in exercise-trained individuals. Subjects will report to the lab on three separate occasions to consume one of the 3 drinks (hydration multiplier, sugar-free hydration matrix, or water), in random order. The drinks will be consumed during the post-exercise period (30 minutes following the completion of exercise).
The primary objective of this study is to analyze smart phone-based Transdermal Optical Imaging (TOI) features to develop a model that can discern hypohydration from euhydration status including 1) a small feasibility study for 24-hour data collection in the general population using passive dehydration or ad libitum fluid intake (GENPOP), 2) an exercise study in moderately active participants in both dehydrated and euhydrated states (EXERCISE). TOI data will be collected alongside standard reference measures of hydration status. This is an exploratory pilot proof of concept study with each subject serving as their own control.
The goal of this clinical trial is to compare betaine supplementation to placebo in firefighters undergoing live burn training regarding thermoregulation and inflammation. The main questions it aims to answer are: - Does betaine supplementation mitigate rises in core temperature during firefighter live burn training? - Does betaine supplementation decrease inflammation from firefighter training? - Does betaine supplementation increase total body water stores? Participants will supplement with betaine for 1 month and complete: - Total Body Water measures - Body Composition measures - Live Burn training with Core Temperature Measurements - Provide Salivary samples
