Filter by:The primary aim of this study is to conduct a well-designed trial to investigate the effect of an MBI program entitled Mindfulness-based Peak Performance (MBPP) on endurance performance under pressure from an interdisciplinary approach of sport psychology, sports training, and cognitive neuroscience. The secondary aim is to examine the effect of MBPP program on performance-relevant mental attributes in behavioral and neurocognitive assessments. The present study hypothesizes that the MBPP and self-talk groups will improve performance under pressure, but MBPP is expected to show greater improvement than ST. Additionally, we expect the MBPP will improve the relevant mental attributes.
This study have like aim to examine whether insulin secretagogues have a potential ergogenic effect leading to a better exercise performance and post-exercise recovery in healthy individuals after a resistance training session. METHODS: This is a randomized, double-blind, placebo-controlled, clinical trial. The sample will consist of 44 men. Subjects will be randomly allocated (block randomization, www.randomizer.org) to the following groups: placebo (PFG, n=22) and sulphonylurea (GFS, n=22). The study will consist of 3 visits 7 days apart. On visit 1 the participants will ask to sign an informed consent form and will carry out medical evaluation with anthropometric assessment. At that visit they will perform a one-repetition maximum test of the upper limbs by using the horizontal bench press and of the lower limbs by using the 45º leg press. On visit 2, they will perform a second round of similar 1-RM tests to determine workloads for the study session [sulphonylurea (gliclazide) vs. placebo]. The experimental exercise session will be held on visits 3. Gliclazide modified release 60 mg (Diamicron® MR) or placebo (starch, sodium lauryl sulfate and Aerosil) will be orally administered as matched capsules (same color, flavor, smell and size) 8 hours before the beginning of exercise session, double-blind. In the experimental session, first, warm-up on the bench press and leg press, both with workload at 50% of 1-RM will be carried out. After a 2-minute rest, the resistance training session will be started. It will consist of 4 sets of bench press and leg press exercises at 65% of 1-RM with maximum repetitions until concentric failure. The bench press exercises will be followed by the leg press exercises with no interval between them. A 2-minute interval will allowed after each series of exercises. Measurements for heart rate (HR) and Visual Analogue Scale (VAS) for Pain will be taken before, between each series of exercises and 24 and 48 hours after session. Venous blood samples will be obtained before, immediately after, 24 and 48 hours after, for determining serum levels of creatine kinase isoenzyme MM and lactate dehydrogenase. Capillary blood for glucose determination will be collected from the digital pulp using a glucometer before and immediately after. Resistance training volume will be calculated for each type of exercise as well as total training volume for each session as a product of exercise workload and number of series and repetitions.
A six-week upper body plyometric training program will be used to investigate its impact on fast bowling speed in junior male cricket players in Guyana, using a Stalker Sport 2 radar gun.
