Filter by:The goal of this tudy will be to investigate the effects of a single session of hyperbaric oxygen therapy (HBOT) on recovery and performance after a football match in elite youth football players. The main questions this study will aim to answer are: Will a single session of HBOT improve recovery parameters such as biochemical markers and physical fitness in elite youth football players after a football match? Will a single session of HBOT enhance the performance of elite youth football players after a football match? Participants in this study will include twenty elite youth male football players. They will be randomly assigned to either the HBOT group or the control group. All participants will undergo evaluations for biochemical parameters, physical fitness tests, and the Hooper Index (HI) at multiple time points: before the match, at the end of the match, one hour after the HBOT session, and 12 hours after the HBOT session. In the HBOT group, participants will receive 100% oxygen under elevated pressure in a hyperbaric chamber for a duration of 70 minutes immediately after the football match. Meanwhile, the control group will be exposed to normal atmospheric pressure. Biochemical analysis will involve collecting blood samples to measure markers such as myoglobin, creatine kinase, lactate dehydrogenase, alanine aminotransferase, and aspartate aminotransferase. Physical fitness tests will include vertical jump height measurements (squat jump, countermovement jump, and countermovement jump with arm swing) and linear speed assessments at various distances (5 m, 10 m, and 20 m). The Hooper Index (HI) will be used for subjective assessment of fatigue and well-being. This study aims to provide insights into the potential benefits of HBOT as a recovery strategy for elite youth football players and its impact on performance in the future.
The overall goal of this study is to investigate the effects of a 6-week training program between two hamstring exercises-the Romanian deadlift (RDL) and the Nordic hamstring exercise (NHE)-on hamstring strain injury risk factors and sprint performance.
In recent years, photobiomodulation has been studied as a means of increasing muscle performance in athletes and healthy individuals. This is possible due to the physiological changes that photobiomodulation therapy can promote. Moreover, given a large number of existing studies on the subject, some directions for future research have been established. For example, future research was established, the relationship between power and time because with high power, it will achieve the same energy with shorter application times. However, irradiation may not be offered for the minimum recommended time. Therefore, this study aims to compare different powers and, consequently, different application times for muscle performance in healthy individuals. For this, 42 participants will be recruited, males between 18 to 40 years old, without recent musculoskeletal injury or cardiorespiratory problems. The participants will participate in 3 evaluations containing functional and physiological variables and ten training sessions of lower limbs with previous photobiomodulation therapy application, comparing devices with a power of 0.864W and 1.864W. 0.864W and 1.2W. Lower limbs training will be composed of stiff and squat exercises twice a week, for five weeks. In the pre- and post-intervention evaluations, the following parameters will be evaluated isokinetic apparatus, body composition, and functionality of the vertical jump. For data analysis, we will use a normality test to verify the distribution and statistical tests will be used for intra and intra and intergroup comparisons, considering two factors in the comparisons time and group. A significance level of 5% will be adopted.
Randomized, placebo-controlled, double-blind, placebo-controlled clinical trial consisting of 15 triathletes in which it is intended to observe less inflammatory damage at the muscular level after performing eccentric exercises.
Background: Photobiomodulation has been explored for years, with wide clinical use for wound healing and analgesia in varied orthopedic conditions, but the number of research and clinical use has increased during the last decade. Furthermore, considering the performance, the current literature is conflicting and restricted, with divergences in wavelength, power and energy density applied. Therefore, analyze different doses for a answer in short and long time, associated with capacities of strength, fatigue resistance and functional performance of handball players and healthy individuals becomes necessary. Objective: To analyze the effects of the application of LED photobiomodulation on the capacities of strength, functional efficiency, temperature and fatigue resistance of handball players and healthy individuals. Method: The study sample will be composed of 56 male individuals randomly allocated into four groups: LED 50J (G-50J), LED 240J (G-240J), LED 50-240J (G-50-240J) - progressive dose and Sham (G-S). The volunteers will be submitted to an evaluation of muscle performance and functional performance, metabolic, and physiological evaluation. After initial tests, in five consecutive weeks, the LEDT (940nm - infrared) will be applied to the quadriceps femoris muscle and hamstrings, bilaterally, associated with a muscle strength protocol. After 24 hours of the last application TLED, the tests will be repeated. Seven days after the last intervention will be performed a follow-up. For analysis, normality tests will be used to verify the distribution and adequate statistical tests for the appropriate intra and intergroup comparisons, being considered two factors in the comparisons, time, and group. A significance level of 5% will be adopted.
The purpose of this study was to verify the effect of 10-day sodium bicarbonate (NaHCO3) and placebo (PLA) supplementation on physical and specific performance capacity, as well as concentrations of the selected biochemical blood markers in trained combat sports athletes, in a randomised, double-blind, placebo-controlled trial.
The purpose of this study was to verify the effect of 10-day sodium bicarbonate (NaHCO3) and placebo (PLA) supplementation on body composition, physical capacity, as well as concentrations of the selected biochemical blood markers in trained athletes, in a randomised, double-blind, placebo-controlled crossover trial.
The purpose of the present study was to assess the influence of low vs moderate glycemic index of a 3-week diet on aerobic capacity, endurance performance and body mass and composition in endurance-trained athletes in a randomized, controlled crossover trial.
The purpose of this study was to verify the effect of 12-week with β-hydroxy-β-methylbutyrate (HMB) and a placebo (PLA) supplementation on body composition, anaerobic and aerobic capacity, as well as concentrations of the selected biochemical blood markers in trained athletes, in a randomised, double-blind, placebo-controlled crossover trial.
