Identifying the trajectory and spin of the ball with speed and accuracy is critical for good performance in table tennis. The aim of this study was to analyze the ability of table tennis players presenting different levels of training/experience to identify the magnitude of the ball spin from the sound produced when the racket hit the ball. Four types of "forehand" contact sounds were collected in the laboratory, defined as: Fast Spin (spinning ball forward at 140 r/s); Medium Spin (105 r/s); Slow Spin (84 r/s); and Flat Hit (less than 60 r/s)...

We investigated the effect of moderate versus high-intensity interval exercise training on the HRV indices in physically inactive adults. Twenty inactive adults were randomly allocated to receive either moderate intensity training (MCT group) or high-intensity interval training (HIT group). The MCT group performed aerobic training at an intensity of 55-75%, which consisted of walking on a treadmill at 60-80% of the maximum heart rate (HRmax) until the expenditure of 300 kcal. The HIT group ran on a treadmill for 4 minutes at 85-95% peak HRmax and had a recovery of 4 minutes at 65% peak HRmax until the expenditure of 300 kcal...

PURPOSE: Quantifying external workload is fundamental to training prescription in sport. In tennis, global positioning data are imprecise and fail to capture hitting loads. The current gold standard (manual notation) is time intensive and often not possible given players' heavy travel schedules. The aim of this study was to develop an automated stroke classification system to help quantify hitting load in tennis. METHODS: 18 athletes wore an inertial measurement unit (IMU) on their wrist during 66 video-recorded training sessions...

BACKGROUND: Chronic Migraine (CM) is a disabling condition, worsened when associated with Medication Overuse (MO). Mindfulness is an emerging technique, effective in different pain conditions, but it has yet to be explored for CM-MO. We report the results of a study assessing a one-year course of patients' status, with the hypothesis that the effectiveness of a mindfulness-based approach would be similar to that of conventional prophylactic treatments. METHODS: Patients with CM-MO (code 1...

The aim of this study was to compare perceived TL (sRPE-TL), training volume (TV) and the changes in physical fitness between professional (n=14) and semi-professional (n=18) basketball players during the preparation period. Furthermore, relationships between sRPE-TL and TV with changes in physical fitness level were investigated. The players performed the Yo-Yo Intermittent Recovery Test (Yo-Yo IR1) before and after the preparation period. In addition, physiological responses to a standardized 6-min continuous running test (Mognoni's test) and to a standardized 5-min high-intensity intermittent running test (HIT) were measured...

OBJECTIVES: Recent literature suggests reduced benefits associated with high intensity (HIT) and or sustained intensity exercise training (SIT). While important, they tend to contrast with other studies of HIT and SIT and may not be representative of all individuals wishing to participate in activities such as marathon running. The purpose of this observational report is to describe a 45-year history of 54 long distance runners, their incidence of death from cardiovascular disease and their ages at death compared to the normal population...

: Introduction Research suggests Emergency Medical Services (EMS) over-use in urban cities is partly due to substance users with limited access to medical/social services. Recent efforts to deliver brief, motivational messages to encourage these individuals to enter treatment have not considered EMS providers. Problem Little research has been done with EMS providers who serve substance-using patients. The EMS providers were interviewed about participating in a pilot program where they would be trained to screen their patients for substance abuse and encourage them to enter drug treatment...

BACKGROUND: Despite the availability of practical knowledge and effective interventions required to reduce priority health problems in low-income countries, poor and vulnerable populations are often not reached. One possible solution to this problem is the use of Community or Lay Health Workers (CLHWs). So far, however, the development of sustainability in CLHW programs has failed and high attrition rates continue to pose a challenge. We propose that the roles and interests which support community health work should emerge directly from the way in which health is organized at community level...

BACKGROUND: High intensity training (HIT) is superior to moderate aerobic training (MAT) for improving quality of life in congestive heart failure (CHF) patients. Speckle tracking echocardiography (STE) has recently been suggested for estimation of left ventricle global and regional function. AIMS: We evaluated the utility of STE for characterizing differences in cardiac function following MAT or HIT in a CHF rat model. METHODS AND RESULTS: Following baseline physiological assessment, CHF was induced by coronary artery ligation in Sprague-Dawley rats...

Inhibitor kappa-B kinase-beta (IKK-β) controls the activation of nuclear transcription factor kappa-B and has been linked to inflammation and cancer. Therefore, inhibitors of this kinase should have potent anti-inflammatory and anticancer properties. Accordingly, we explored the pharmacophoric space of 218 IKK-β inhibitors to identify high-quality binding models. Subsequently, genetic algorithm-based quantitative structure activity relationship (QSAR) analysis was employed to select the best possible combination of pharmacophoric models and physicochemical descriptors that explain bioactivity variation among training compounds...

This is the first study to show that enjoyment for high-intensity interval exercise increases with chronic training. Prior acute studies typically report high-intensity interval training (HIT) as being more enjoyable than moderate continuous training (MCT) unless the high-intensity intervals are too strenuous or difficult to complete. It follows that exercise competency may be a critical factor contributing to the enjoyment of HIT, and therefore building competency through chronic training may be one way to increase its enjoyment...
