High intensity physical exercise has previously been found to lead to a decline in cognitive performance of adults. The aim of this study was to determine the effects of maximal intensity exercise on cognitive performance of children. Using a repeated-measures design, 20 children and adolescents aged 8-17 years completed a battery of tests measuring memory and attention. Forward and Backward Digit Span tests, the Rey Auditory-Verbal Learning Test (RAVLT) and the Digit Symbol Substitution Test (DSST) were performed at baseline, immediately after, and one hour after a maximal cardiopulmonary exercise test...

Laparoscopic TAPP inguinal hernia repair is an established alternative to open hernia repair, which offers equivalent outcomes with less postoperative pain and faster recovery. Unfortunately, it remains technically challenging, requiring advanced laparoscopic skills which have limited its popularity among surgeons. The robotic platform has the potential to overcome these challenges. The objective of this study was to examine the long-term quality of life and outcomes following robotic assisted TAPP inguinal hernia repair, since these data have not been reported up to now...

The aim of this study was to analyze the recovery of heart rate variability (HRV) after treadmill exercise and to investigate the autonomic nervous system response after exercise. Frequency domain indices, i.e., LF(ms(2)), HF(ms(2)), LF(n.u.), HF(n.u.) and LF/HF, and lagged Poincaré plot width (SD1 m ) and length (SD2 m ) were introduced for comparison between the baseline period (Pre-E) before treadmill running and two periods after treadmill running (Post-E1 and Post-E2). The correlations between lagged Poincaré plot indices and frequency domain indices were applied to reveal the long-range correlation between linear and nonlinear indices during the recovery of HRV...

No study has concurrently measured changes in free-living whole body protein metabolism and exercise performance during recovery from an acute bout of resistance exercise. We aimed to determine if whey protein ingestion enhances whole body net protein balance and recovery of exercise performance during overnight (10 h) and 24 h recovery after whole body resistance exercise in trained men. In a double-blind crossover design, 12 trained men (76 ± 8 kg, 24 ± 4 years old, 14% ± 5% body fat; means ± standard deviation (SD)) performed resistance exercise in the evening prior to consuming either 25 g of whey protein (PRO; MuscleTech 100% Whey) or an energy-matched placebo (CHO) immediately post-exercise (0 h), and again the following morning (~10 h of recovery)...

PURPOSE: Currently, cortical voluntary activation (VATMS) is assessed by superimposing transcranial magnetic stimulation (TMS) on a maximal voluntary contraction (MVC), 75% MVC and 50% MVC, each contraction being interspersed with 5-10 s of relaxation. Here, we assessed whether this traditional approach (TRADI) underestimates central fatigue due to this short recovery compared to a continuous method (CONTI). METHODS: VATMS, motor-evoked potential (MEP), and cortical silent period (CSP) of the vastus lateralis were determined in 12 young healthy adults before and after a 2-min sustained MVC of knee extensors in two randomly assigned sessions...

The dose and timing of post-exercise protein ingestion can influence WBPB in adults, although comparable data from children are scarce. This study investigated how protein intake (both, amount and distribution) post-exercise can affect WBPB in physically active children. Thirty-five children (26 males; 9-13 years old) underwent a 5-d adaptation diet consuming 0.95 g protein·kg-1·d-1. To assess whole body protein kinetics over 6h and 24h of recovery, participants consumed 2 mg·kg-1 [15N]glycine before performing 3 × 20-min of variable intensity cycling...

Excessive positive energy balance is a major factor leading to obesity. The ability to alter the appetite-regulating hormones leptin, adiponectin, and ghrelin may help decrease excessive energy intake. Exercise and exposure to extreme temperatures can independently affect these appetite-regulating hormones. PURPOSE: To determine the effect of exercising in different environmental conditions on the circulating concentrations of leptin, adiponectin, and ghrelin. METHODS: Eleven recreationally-trained male participants completed 3 separate 1 h cycling bouts at 60% Wmax in hot, cold, and room temperature conditions (33°C, 7°C, 20°C), followed by a 3 h recovery at room temperature...

BACKGROUND: An acute bout of eccentric contractions (ECC) cause muscle fiber damage, inflammation, impaired muscle function (MF) and muscle soreness (MS). Individually, protein (PRO) and antioxidant (AO) supplementation may improve some aspects of recovery from ECC, though have yet to be combined. We sought to determine if combined PRO and AO supplementation (PRO + AO) improves MS and MF following damaging ECC over PRO alone. METHODS: Sixty sedentary college-aged males participated in a randomized, single-blind, parallel design study of peak isometric torque (PIMT), peak isokinetic torque (PIKT), thigh circumference (TC), and muscle soreness (MS) of knee extensor muscles measured at baseline, immediately after and 1, 2, 6, and 24 h after completion of 100 maximal ECC...

We investigated the underlying molecular mechanisms by which post-exercise cold-water immersion (CWI) may alter key markers of mitochondrial biogenesis following both a single session and six weeks of sprint interval training (SIT). Nineteen males performed a single SIT session, followed by one of two 15-min recovery conditions: cold-water immersion (COLD; 10°C) or a passive room-temperature control (CON; 23°C). Sixteen of these participants also completed six weeks SIT, each session followed immediately by their designated recovery condition...

INTRODUCTION: Physical exercise after stroke is essential for improving recovery and general health, and reducing future stroke risk. However, people with stroke are not sufficiently active on return to the community after rehabilitation. We developed the Promoting Optimal Physical Exercise for Life (PROPEL) programme, which combines exercise with self-management strategies within rehabilitation to promote ongoing physical activity in the community after rehabilitation. This study aims to evaluate the effect of PROPEL on long-term participation in exercise after discharge from stroke rehabilitation...
