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.
Pain in physically disabled athletes affects the sporting career directly or indirectly through psychological consequences. Numerous studies address psychological skills in able-bodied athletes and in able-bodied athletes they are scarce.This information is part of a research project aimed at finding resources to help athletes in their pain management.
This study is intended to investigate the use of probiotics (LAB4 probiotics, Cultech, Port Talbot, Wales, UK) and the effect this has on gastrointestinal symptoms experienced during elite long-distance triathlon (ironman) competition, as well as the composition of the gut bacteria in the athlete. Long-distance triathlon events frequently induce gastrointestinal discomfort due to the duration of the event (8-17 hours), the intensity of the exercise and the ingestion of large amounts of sugars throughout the event. Data will be collected from athletes participating at the Kona ironman World-championships. Participants will supplement with either probiotic tablet, or placebo (sugar-pill) for 4-weeks prior to competition. Athletes will be both male and female age-group athletes from any qualifying age category (age categories are as follows: 18-24; 25-29; 30-34; 35-39; 40-44; 45-49; 50-54; 55-59; 60-64; 65-69; 70-74; 75-79; 80-84). The main investigation of the study will be the occurence/frequency/severity of gastrointestinal symptoms during training and competition between groups.
Orthopedic Manual Therapy (OMT) is one of the branches of physiotherapy that has less evidence about its action and efficacy, but those who have had the opportunity to apply or receive it know its great benefits. Currently, worldwide, the approach given to physiotherapy goes hand in hand with the guidelines of the TMO, but in Colombia it is not seen in the same way. The objective of this TFM is to compare the effects of Finding-Oriented Orthopedic Manual Therapy combined with Foam Roller versus the effects of Foam Roller alone, specifically in terms of muscle power and lower limb flexibility in Colombian athletes. For this, a randomized controlled clinical trial will be carried out with two groups that will undergo different interventions. To measure the variables, the CMJ jump protocol will be used with the Optogait and the Wells or sit and reach test.
Background: Sport is a specialized competitive physical activity that is regulated and requires daily physical training. The workouts allow athletes to increase strength, endurance exercise performance, and muscle mass. Due to this, it is extremely important to consider that high-performance athletes require a meal plan with a higher energy requirement compared to a normal person who does not perform high-intensity activity. The diet of these athletes needs higher protein requirements to support the accumulation and/or maintenance of lean mass. Specifically athletes between 4 to 17 years of age, the protein requirement is of utmost importance to maintain muscle mass between 68-73%. Therefore, the recommendations for protein intake for athletes in this age range is approximately between 10 and 30% of the total energy intake. One of the strategies that has been used is supplementation with protein isolates, since in this way there is greater protein accessibility to maintain a balance between protein synthesis and degradation. The main protein supplements that are currently consumed come from proteins of animal origin; however, these usually have high costs, which makes them difficult to access for the population. Due to this, strategies have begun to be sought through the use of different proteins to generate similar effects. Objective: To evaluate the effect of a bean protein supplement on body composition in high-performance adolescent athletes. Methodology: The protocol will be divided into two stages, in the first one a supplement added with bean protein will be elaborated. First, the extraction of protein from the bean will be carried out, then it will be subjected to a heat treatment to eliminate anti-nutrients and finally its chemical composition will be analyzed. In the second stage, a pilot study will be carried out to evaluate the effect of the bean protein supplement in high-performance adolescent athletes. High-performance table tennis athletes, adolescents who agree to collaborate with the study will be included. Bean protein supplementation will be for 21 continuous days in the athletes' snack. Anthropometric measurements will be taken at the beginning and at the end of the intervention. A control of the diet and supplementation of the athletes will be carried out with the support of their coaches.
The main goal of this project is to study and define a rehabilitative flow-chart for athletes' rehabilitation and return to sport made by a set of objective shoulder evaluation indicators that are easy to use in clinical context. Enrolled patients will undergo supervised rehabilitation treatment for rotator cuff repair according to a standardized protocol (5 days/week) and will undergo four evaluation at different times. Healthy subjects will undergo evaluations with the same timing as patients.
Citrulline (CIT) and nitrate-rich beetroot extract (BEET) are widely studied ergogenic aids. However, both supplements have been studied in sort-term and isolated. To the best of the authors' knowledge, the effects of combining both supplements on exercise-induced muscle damage (EIMD) and hormone status have not been investigated to date. Therefore, the main purpose of this study was to determine the effect and degree of potentiation of the long-term (9 weeks) mixture of 3 g/day of CIT plus 2.1 g/day of BEET (300 mg/day of NIT) supplementation on EIMD markers (urea, creatinine, AST, ALT, GGT, LDH and CK) and anabolic/catabolic hormone status (testosterone, cortisol and Testosterone cortisol ratio (T/C)) in male trained triathletes. This study was a double-blind, placebo-controlled trial where participants (n = 32) were randomized into 4 different groups: placebo group (PLG; n = 8), CIT group (CITG; 3 g/day of CIT; n = 8), BEET group (BEETG; 2.1 g/day of BEET (300 mg/day of NIT) ; n = 8) and CIT-NIT group (CIT-BEETG; 3 g/day of CIT plus 2.1 g/day of BEET (300 mg/day of NIT); n = 8). Blood samples were collected from all participants at baseline (T1) and after 9 weeks of supplementation (T2).
This investigation aims to apply and test the feasibility of a structured Program for young athletes. PLAYwithHEART is a program for promoting acceptance and cooperation skills in adolescent athletes. This group application program comprises eight weekly sessions and aims to decrease levels of sport anxiety, and increase the psychological quality of life of young athletes, by promoting skills inherent to an affiliation mentality (mindfulness, acceptance, and compassion), as an alternative to a social ranking mentality (based on maladaptive processes, such as shame and self-criticism), to deal with the challenges and demands of the sport context.
The experimental procedures will be composed of two sessions. The following steps will be constituted the first session: warm-up on the cycle ergometer, and familiarization with the isokinetic dynamometer then baseline measurement of isokinetic parameters. Afterward, the placebo or active TECAR therapy will be applied (according to the randomization). At the end, isokinetic parameters will be taken again. After 7 days, the second session will be performed following identical procedures to the first session. However, an inverse mode of TECAR therapy from the first session (placebo or active) will be applied for each individual. The two sessions will be held 7 days apart, either on a Sunday or Tuesday. Procedures are summarized in Figure 1. The dominant lower limb test will be used to elect the lower limb selected for isokinetic Dynamometer. Figure 1: Timeline for the period of evaluation of groups (Active and Placebo TECAR). Muscle performance measurement by Isokinetic Dynamometer: The quadriceps muscles of dominant lower limb will be tested for all participants with Biodex isokinetic dynamometer (Biodex Medical System, Shiley, NY, USA, linked to IBM PC-computer software). Calibration of the Biodex for torque and angular speed will be done according to the prescribed manufacturer's guidelines before each recording session. Prior to assessment, the volunteers held a 5-min cycle ergometer warm up (speed in the range of 60-70 rpm and no load). After that, participants will be positioned with hip angle of 100o on the previously calibrated isokinetic dynamometer and will be properly aligned and stabilized with straps in order to avoid possible compensatory movements. Thus, the dominant knee axis (lateral epicondyle of the femur) of each subject was adjusted to the dynamometer rotation axis. The lever arm of the equipment was fixed approximately 2 cm above the tibial malleolus. The chair height, backrest distance, seat angle, and dynamometer base were adjusted for each subject and noted for the second session. Before starting the recording of isokinetic muscle performance, there will be a familiarization period with the apparatus consisting of five submaximal voluntary concentric muscle contractions in the full range of standardized and preprogrammed motion (90-20°) according to the guideline procedures of the dynamometer, with a constant angular velocity of 180°/s. the isokinetic protocol will be performed with a set of 60 concentric/eccentric contractions of quadriceps. The participants will be visually and verbally encouraged throughout the test protocol to achieve maximum effort from the beginning. The muscle performance, in terms of work fatigue index, peak torque, average power, and total work of the knee extensor muscles, will be evaluated by isokinetic dynamometry in accordance with the guidelines of the equipment manufacturer (Biodex Medical System Inc.). Experimental protocol of TECAR therapy: Immediately after the baseline measurement of muscle performance of each session, the participants will be received placebo or active TECAR therapy. In this experiment, Transfer Electrode Capacitive and Resistive (TECAR) Therapy (radio frequency therapy; INDIBA, Spain) will be used. TECAR therapy is a systematic treatment for providing capacitive energy transfer (CET) and resistive energy transfer (RET). In CET mode, heat transfer is concentrated on the skin and superficial muscles, which are tissue with high electrolytes, while the RET mode focuses heat transfer on bones, tendons, joints, and deep muscles. In this study, both CET and RET modes will be applied to the participant' quadriceps for 15-20 minutes at stable frequency of 448 KHz. According to the manufacturer's guidelines for safety, the CET mode will be first implemented for 5 minutes. Then will be continued in RET mode using for the rest of the treatment. Participants will be asked to lie down comfortably, and treatment will be beginning. The intensity of the current will be set at the level of comfort between 0%-100%, averaging about 40%. TECAR therapy will be applied by a physical therapist for all participants.
