BACKGROUND: Hands-on training in point-of-care ultrasound (POC-US) should ideally comprise bedside teaching, as well as simulated clinical scenarios. High-fidelity phantoms and portable ultrasound simulation systems are commercially available, however, at considerable costs. This limits their suitability for medical schools. A Linux-based software for Emergency Department Ultrasound Simulation (edus2TM) was developed by Kulyk and Olszynski in 2011. Its feasibility for POC-US education has been well-documented, and shows good acceptance...

Regular physical activity has shown to improve the quality of life and to prevent age-related memory deficits. Memory processing requires proper regulation of several enzymes such as sodium-potassium adenosine triphosphatase (Na(+), K(+)-ATPase) and acetylcholinesterase (AChE), which have a pivotal role in neuronal transmission. The present study investigated the effects of a treadmill running protocol in young (3 months), mature (6 months) and aged (22 months) Wistar rats, on: (a) cognitive function, as assessed in the Water maze spatial tasks; (b) Na(+), K(+)-ATPase and AChE activities in the hippocampus following cognitive training alone or treadmill running combined with cognitive training...

BACKGROUND: Approximately 2 of every 3 competitive runners sustain at least 1 health problem each season. Most of these problems are nontraumatic injuries with gradual onset. The main known risk indicator for sustaining a new running-related injury episode is a history of a previous injury, suggesting that behavioral habits are part of the causal mechanisms. PURPOSE: Identification of elements associated with purposeful interpretations of body perceptions and balanced behavioral responses may supply vital information for prevention of health problems in runners...

We tested the hypothesis that a 6-week regimen of simvastatin would attenuate skeletal muscle adaptation to low-intensity exercise. Male C57BL/6J wildtype mice were subjected to 6-weeks of voluntary wheel running or normal cage activities with or without simvastatin treatment (20 mg/kg/d, n = 7-8 per group). Adaptations in in vivo fatigue resistance were determined by a treadmill running test, and by ankle plantarflexor contractile assessment. The tibialis anterior, gastrocnemius, and plantaris muscles were evaluated for exercised-induced mitochondrial adaptations (i...

Cerebellar peduncles (CPs) are white matter tracts connecting the cerebellum to other brain regions. Automatic segmentation methods of the CPs have been proposed for studying their structure and function. Usually the performance of these methods is evaluated by comparing segmentation results with manual delineations (ground truth). However, when a segmentation method is run on new data (for which no ground truth exists) it is highly desirable to efficiently detect and assess algorithm failures so that these cases can be excluded from scientific analysis...

CONTEXT: About two-third of patients with mental, neurological, and substance use disorder in India do not get adequate treatment due to insufficient clinical facilities. In a country with diverse population such as India, no single model can be effective and each region needs to develop local system of service delivery unique to population needs. Community outreach clinics (COCs) being run by the department of psychiatry provide mental health services in the primary health-care setting...

The purpose of this study was to compare the effects of 2 high-intensity interval training protocols (HIIT) with different interval durations (short (SI) vs long (LI)), based on peak running velocity in 30-15 Intermittent Fitness Test (VIFT) in handball players. Eighteen highly trained players (age: 22.7±3.9 years; height: 181.5±6.6 cm; body mass: 84.7±14.1 kg) were randomly assigned to SI (2 sets of 22 intervals of 10-s runs at 95%VIFT) or LI (5 sets of 3 min intervals at 85% VIFT) group. The intervention program had to be carried out 2 times a week over 6 weeks...

This study aimed to analyse the influence of muscular performance parameters on spatio-temporal gait characteristics during running when gradually increasing speed. 51 recreationally trained male endurance runners (age: 28 ± 8 years) voluntarily participated in this study. Subjects performed a battery of jumping tests (squat jump, countermovement jump, and 20 cm drop jump), and after that, the subjects performed an incremental running test (10 to 20 km/h) on a motorized treadmill. Spatio-temporal parameters were measured using the OptoGait system...

Cooling treatment is regarded as one of good practices to provide safe training conditions to athletic trainers in the hot environment. The present study aimed to investigate whether wearing a commercial lightweight and portable hybrid cooling vest that combines air ventilation fans with frozen gel packs was an effective means to reduce participants' body heat strain. In this within-subject repeated measures study, 10 male volunteers participated in two heat-stress trials (one with the cooling vest - COOL condition, and another without - CON condition, in a randomized order) inside a climatic chamber with a controlled ambient temperature 33 °C and relative humidity (RH) 75% on an experimental day...

A feature of healthy human walking gait is a clearly defined heel-strike at initial contact, known as heel-to-toe gait. However, a common consequence of ageing is the deterioration of this heel first gait towards a flat foot, or 'shuffling' gait. This leads to a shortened stride length, slowed gait speed, and an increased fall risk. Shuffling gait is normally treated by physiotherapy, however, therapist time is limited and training is restricted to a clinical environment. Gait rehabilitation could be expedited with the use of a device that distinguishes between heel-to-toe and shuffling gait and gives feedback to the user...

In mice, transgenic manipulation of Ca(2+)-handling proteins is sufficient to alter the metabolic phenotype of muscle. We have previously shown that ablation of sarcolipin (SLN), a regulatory protein and uncoupler of sarco(endo)plasmic reticulum Ca(2+)-ATPases, leads to excessive diet-induced obesity and glucose intolerance in mice. However, it is unclear how loss of SLN per se affects muscle oxidative capacity and the ability of mitochondria to adapt to physiological stimuli such as exercise training or calorie overload...

PURPOSE: Previous investigations of player load in netball have utilised subjective methodologies, with few utilising objective methodologies. Whilst all studies report differences in player activities or total load between playing positions, it is unclear how the differences in player activity explain differences in positional load. The aim of this study was to objectively quantify the load associated with typical activities for all positions in elite netball. METHODS: The player load of all playing positions in an elite netball team, was measured during matches using wearable accelerometers...

This study aimed to validate the use of a single blood lactate concentration measurement taken following a 5-min running bout at 10 km·h(-1) (BLC10 ) and the speed associated with 90% of maximal heart rate (S90 ) to predict and monitor fixed blood lactate concentration (FBLC) thresholds in athletes. Three complementary studies were undertaken. Study-I: A cross-sectional study examining the associations of BLC10 and S90 with running speeds at FBLC of 3 (S3mM) and 4 mmol·L(-1) (S4mM) in 100 athletes. Study-II: A cross-validation study assessing the predictive capacity of BLC10 and S90 to estimate FBLC thresholds in real practice...

This study investigated the effect of 5 days controlled hyperthermia heat acclimation (STHA) on the determinants of endurance performance and 5 km performance in runners, relative to the impairment afforded by moderate heat stress. A control group (CON), matched for total work and power output (2.7 W.kg-1), differentiated thermal and exercise contributions of STHA on exercise performance. Seventeen participants (10 STHA, 7 CON) completed graded exercise tests (GXT) in cool (13°C, 50% RH, pre training) and hot conditions (32°C, 60% RH, pre and post training), as well as 5 km time trials (TT) in the heat, pre and post training...

Sprint-interval training (SIT) is a viable method to improve health and fitness. However, researchers have questioned the utility of SIT due to its strenuous nature. The current study aimed to determine if manipulating the sprint and recovery duration, while maintaining the 1:8 work to rest ratio, could uncover a more favourable SIT protocol. Nine healthy active males (23.3±3.0 y, 22.4±2.2 kg·m<sup>-2</sup>, 48.9±5.3 mLkg<sup>-1</sup>min<sup>-1</sup>) participated in three experimental running SIT sessions: (1) 30:240 (4 x 30 sec efforts, 240 sec recovery); (2) 15:120 (8 x 15 sec efforts, 120 sec recovery); (3) 5:40 (24 x 5 sec efforts, 40 sec recovery); and (4) a final behavioural choice follow-up session...
