Filter by:This study aims to investigate the musculotendinous adaptations in the Achilles tendon and the muscles composing the triceps surae induced by triathlon training and competitions in high-performance and low-performance athletes. Twenty high-performance triathletes, twenty low-performance triathletes, and twenty physically active and healthy individuals of both genders will be recruited to constitute the research groups. Ultrasonography will be employed as the assessment method for the structures of the Achilles tendon and the muscular architecture of the triceps surae. The quality and portability of ultrasonography, coupled with its real-time information capabilities, make it the appropriate choice for this evaluation. The VISA-A scale (Victorian Institute of Sport Achilles Assessment) will be used to measure pain and function of the Achilles tendon. The reliability of ultrasonography measures will be obtained by evaluating images of individuals using the intraclass correlation coefficient, allowing for the analysis of result reproducibility. Data analysis will involve comparisons among the high-performance, low-performance, and physically active groups, aiming to identify differences in musculotendinous adaptations related to performance and injury predisposition. Structural changes occurring in these structures and their potential association with sports performance and/or injury predisposition will be explored. Overall, this study utilizes a comparative cross-sectional research design, where different groups are assessed regarding musculotendinous adaptations in the Achilles tendon and triceps surae through ultrasound-derived measures. The use of the VISA-A scale and the assessment of measure reliability will provide additional data on pain, function, and result reproducibility.
The performance of Chinese women's badminton singles players is declining to a large extent, the training of badminton in China needs to catch up, and the talent ladder has caused a fault. Badminton Routine training, the effect is not apparent . An essay on the impact of core training on athletes' skill performance was written by Luo; it proves that core strength training plays a positive role in a variety of sports; there is no study of female badminton players. Coaches or sports researchers can use this knowledge to manage the training load of badminton players better, thereby helping badminton players achieve better results in badminton training and competition.
While prior research indicates the efficacy of High-Intensity Functional Training (HIFT) in improving physical fitness and skill performance across various sports , its effects on Wushu routine athletes still need to be determined. This study aims to explore the impact of high-intensity functional training on the physical fitness and jumping difficulty of Wushu routine athletes, providing valuable insights for coaches and athletes to optimize training plans. Coaches or sports researchers can use this knowledge to manage the training load of athletes better, thereby helping Wushu athletes achieve better results in Wushu jumping difficulty movements training.
The Quantum Menstrual Health Monitoring Study will measure four key reproductive hormones in the urine to characterize patterns that predict and confirm ovulation, referenced to serum hormones and the gold-standard of the ultrasound day of ovulation in participants with regular cycles. These normal cycles will provide a reference for comparison to irregular cycles in polycystic ovarian syndrome (PCOS) and athletes. Clinical signs in the menstrual cycle (e.g. menstrual bleeding, temperature) as well as vital sign and sleep patterns will also be referenced to hormonal changes.
Total daily energy expenditure (TDEE) is known as the energy used by an organism during a day. The TDEE is divided into resting energy expenditure (REE), the thermic effect of food (TFE), and the energy expenditure of physical activity. There are multiple methods of measuring REE (e.g., estimating equations, direct and indirect calorimetry) among which there are significant discrepancies in its calculation in specific populations. Considering the lack of validation in the Colombian population to estimate the REE, the objective of the present research study is to compare the methods for estimating resting energy expenditure in the Colombian population with different levels of physical activity. This cross-sectional-observational study will be carried out through the guidelines for strengthening the reporting of observational studies in nutritional epidemiology (STROBE-Nut). The study population will be 130 adults from the city of Medellín, Bogotá and metropolitan areas with different levels of physical activity according to the results of the International Physical Activity Questionnaire (IPA-Q) where a high (athletes), moderate (physically active people) and low (sedentary) categorization will be made, then the indirect calorimetry tests will be applied. The development of the equation to estimate the REE will be carried out with multiple regression models under traditional and Bayesian approaches with three independent variables. It is expected to obtain a simple and valid equation to estimate the REE and contribute to the good practices of Colombian practitioners in health sciences, exercise, and sports.
Introduction: Late-onset muscle pain (DOMS) is characterized by a type of temporary muscle damage, common after high-intensity exercise. In addition to pain, DOMS clinically generates muscle stiffness, reduced joint range of motion, muscle weakness and reduced peak torque. In this regard, in order to accelerate the recovery of body systems and treat symptoms of DOMS, the management of different types of interventions has been observed, supporting the clinical practice, based on evidence. Objectives: To investigate the effect of different types of clinical interventions for the treatment of DOMS. Material and methods: For the clinical trial, 50 ultramarathon and rowing athletes of both sexes, aged between 18 and 60 years old, will be recruited randomly into four possible groups: control (CG), shock waves (G1) , massage (G2) and laser therapy (G3). The evaluation moments will be as follows: minutes before exercise (M1); immediately after exercise (M2); immediately after applying the recovery technique (M3); and 24 hours after exercise (M4) and the evaluated outcomes will be: pain, psychological aspects, functional test and blood markers.
