Filter by:The goal of this study was to investigate the effects of Photobiomodulation therapy (PBMT) on performance, oxygen uptake (VO2 kinetics), and lower limb muscle oxygenation during three successive time-to-exhaustion tests (TTEs) in cyclists. This was a double blind, randomized, crossover, placebo-controlled trial study. Sixteen cyclists (~23 years old), with a cycling training volume of ~460 km/week, volunteered for this study. In the first session, cyclists performed a maximal incremental test to determine maximal oxygen uptake and maximal power output (POMAX). In the following sessions, cyclists performed three consecutive TTEs at POMAX. Before each test, PBMT (135 J/thigh) or a placebo (PLA) PBMT was applied to both thighs. VO2 amplitude, O2 deficit, time delay, oxyhemoglobin (O2Hb), deoxyhemoglobin (HHb), and total hemoglobin (tHb) were measured during tests on the right vastus lateralis. The PBMT, applied before three successive TTE, increased performance of the first and second TTE (~10-12%) tests, speed of VO2 and HHb kinetics during the first test, and increased peripheral muscle oxygenation (increase in HHb and tHb) in the first and second exhaustion tests. However, the PBMT effects were attenuated in the third TTE, as performance and all the other outcomes were similar to the ones from the PLA intervention. In summary, PBMT application increased the first and second successive TTEs, speed of VO2, and muscle oxygenation.

Outcome measures in this study are 'Sit and Reach Test' and 'Weight Bearing Lunge Test'.
Introduction: The practice of stretching is commonly used in the preparation of activities and/or physical exercises that require some component of flexibility, strength, endurance and muscle power. This explains the high growth in recent decades of studies investigating the effect of stretching, mainly static and dynamic, when performed immediately before activities that aim to develop these physical capacities. Despite the growing interest of scholars on this topic, the long-term impact of dynamic stretching on flexibility, strength performance, endurance and muscle power is still not fully understood. In addition, a type of dynamic stretching little explored in the literature needs investigation: the stretches used during Pilates exercise sessions. The effects of these stretching exercises on a physical conditioning program based on Pilates exercises in the young adult population are not yet known. Objective: To verify through a randomized clinical trial the effects of stretching in a conditioning program based on Pilates exercises on flexibility, strength, endurance and muscle power. Methods: In this study, 32 young adults of both sexes will be randomized into two groups: 1) Traditional Pilates; 2) Pilates Without Stretching. The Traditional Pilates group will perform a protocol of stretching exercises followed by muscle strengthening. The Pilates Without Stretching group will perform an exercise protocol consisting only of muscle strengthening exercises. Muscle strength results will be evaluated by 1 repetition max by elastic resistance; trunk muscle strength/endurance by the 1-minute abdominal test and the Sorensen test, respectively; vertical jump performance by the sargent jump test; handgrip strength by the handheld dynamometer and flexibility by the sit-and-reach test. These physical capacities will be assessed at baseline and after 8 weeks of intervention. Interventions will be performed three times a week for 8 weeks. The analysis will be performed with intent-to-treat analysis and adjusted covariance for baseline outcomes.
Objective Structured Clinical Examination (OSCE) is a newly implemented evaluation standard for medical students and is a determinant part of the national competition they have to undergo. Exam periods are significantly associated with increased stress and anxiety which led to reduced performance, impaired memorization and impaired workload capacities. Cardiac biofeedback and mindfulness techniques are efficient methods for stress reduction. Interventions that aim to mobilize competence, such as mobilization of inner strength and resources techniques, should improve the level of preparation of medical students. These three procedures could influence the stress level and improve performance during the OSCE. There is currently no study exploring the effect of these physiological and psychological procedures on the performance during OSCE for medical students.
Aim: The aim of the study was to examine and compare the time-dependent effects of IASTM and FR applications on delayed muscle pain and physical performance. Method: 50 physically active healthy male individuals between the ages of 20-35 will be included in the study. Participants will be divided into 3 separate groups as instrument assisted soft tissue mobilization(IASTM), foam roller (FR) and control group. DOMS creation protocol will be implemented after preliminary evaluation. IASTM and FR groups will be treated after the formation of doms. The control group will not be applied. participants are evaluated 1 day before the doms were created and at 24, 48 and 72 hours after doms created. Subjetcs were tested for physical activity level with IPAQ-SF, flexibility with sit and reach test, pain with Visual analog scale, edema with thigh circumference measurement, explosive power with horizontal and vertical jump test, dynamic balance with y balance test and isokinetic muscle strength of the quadriceps and hamstring muscles with isokinetic dynamometer.
This study was planned to investigate how much the anaerobic performance of individuals who experienced fatigue with Want (Wingate) affected their postural sway parameters.
A randomized, controlled trial to evaluate the effects of two versions of 10 high intensity interval trainings (HIIT) within a 7-day shock microcycle on endurance performance, well-being, health, stress and recovery in trained athletes.
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.
The main objective of this study is to analyse the effect of KT on countermovement jump (CMJ) and sprint immediately and 24 hours after its application on the quadriceps and gluteus maximus.
Aim: Although regional anesthesia (RA) techniques are advantageous in the anesthetic management of obese patients (body mass index (BMI)≥30); their performances can still be associated with technical difficulties and greater failure rates. The aim of this study is to compare the performance properties and analgesic efficacy of ultrasound (US)-guided bilateral thoracic paravertebral blocks (TPVBs) in obese and non-obese patients. Material methods: After obtaining ethics committee approval; data of 82 patients, who underwent elective bilateral reduction mammaplasty under general anesthesia with adjunctive TPVB analgesia between December of 2016 and February of 2020, were reviewed. Patients were allocated into two groups with respect to their BMI scores (Group NO: BMI<30 and Group O: BMI≥30). Demographics, TPVB ideal US image visualization and performance times, needle tip visualisation and TPVB performance difficulties, number of needle maneuvers, surgical, anesthetic and analgesic follow-up parameters, incidence of postoperative nausea vomiting (PONV), sleep duration, length of postanesthesia care unit (PACU) and hospital stay, patient and surgeon satisfaction scores were all investigated and compared.
