Improvements in Walking During Subacute Stroke Rehabilitation Translate to Physical Activity at the Chronic Stage: A Sub-Analysis From the Phys Stroke Trial.

Unlabelled: Stroke frequently results in mobility impairments, contributing to an increased cardiovascular risk. Despite efforts to promote physical activity, stroke survivors fail to meet recommended levels. This secondary analysis of the 'Physical Fitness in Patients with Subacute Stroke' (Phys-Stroke) trial analyzes physical activity at 6 months post-stroke, and examines the effect of gains in walking capacity during the subacute phase on physical activity in the chronic stage.

Effects of aerobic exercise on hippocampal formation volume in people with schizophrenia - a systematic review and meta-analysis with original data from a randomized-controlled trial.

Background: The hippocampal formation represents a key region in the pathophysiology of schizophrenia. Aerobic exercise poses a promising add-on treatment to potentially counteract structural impairments of the hippocampal formation and associated symptomatic burden. However, current evidence regarding exercise effects on the hippocampal formation in schizophrenia is largely heterogeneous.

Effects of high intensity interval training on serum brain-derived neurotrophic factor in individuals with PTSD.

Background: Brain-derived neurotrophic factor (BDNF) is a protein important for synaptic plasticity and formation of memory. It is suggested to play an important role in the development of psychiatric disorders like post-traumatic stress disorder (PTSD). Individuals with PTSD usually show decreased BDNF levels in serum.

Differences in Troponin I and Troponin T Release in High-Performance Athletes Outside of Competition.

Troponin I and troponin T are critical biomarkers for myocardial infarction and damage and are pivotal in cardiological and laboratory diagnostics, including emergency settings. Rapid testing protocols have been developed for urgent care, particularly in emergency outpatient clinics. Studies indicate that strenuous physical activity can cause transient increases in these troponin levels, which are typically considered benign.

Determining Physiological and Energetic Demands during High-Level Pommel Horse Routines Using a Modified Method Based on Heart Rate-Oxygen Uptake Functions.

This study aimed (1) to assess the validity of a modified method (M) based on heart rate (HR)-oxygen uptake (VO) regression functions to calculate total energy costs (W) and aerobic (W) and anaerobic alactic energy contribution (W) and (2) to analyse the physiological and energetic demands of high-level pommel horse routines (PH routines). The M was developed because VO measurements are limited during high-level PH routines. Answering Part 1, nine male artistic gymnasts performed a PH routine where energy costs were calculated from VO measurements and then compared with energy costs determined from the HR- VO regressions of M's two additional tests.
