Background: To compare the acute effects of water-based aerobic-resistance and resistance-aerobic concurrent training (CT) sessions on energy expenditure (EE) during and postexercise in young women.
Methods: Nine active women (24 [3] y; 60 [5] kg) completed 4 sessions: (1) familiarization, (2) aquatic maximal test to determine the heart rate corresponding to the anaerobic threshold, (3) CT protocol with aerobic-resistance sequence, and (4) CT protocol with resistance-aerobic sequence. Both protocols started and ended with the participants in the supine position for 30 minutes to perform resting and postexercise oxygen consumption measurements. The water-based resistance protocol comprised 4 sets of 15 seconds at maximal velocity, and the water-based aerobic protocol was performed at a continuous intensity (heart rate corresponding to the anaerobic threshold). EE measurements were calculated based on oxygen consumption and the corresponding caloric equivalent. Paired t test was used to compare the EE values between the water-based CT intrasession exercise sequences (α = .05).
Results: There was no difference between the water-based aerobic-resistance and resistance-aerobic in total EE (330.78 vs 329.56 kcal; P = .96), EE per minute (7.35 vs 7.32 kcal·min-1; P = .96), and postexercise EE (63.65 vs 59.92 kcal; P = .50).
Conclusions: The intrasession exercise sequence during water-based CT had no influence on the EE in young women.

Intra- and inter-session reliability and repeatability of H magnetic resonance spectroscopy for determining total creatine concentrations in multiple brain regions.
Exp Physiol

Using proton magnetic resonance spectroscopy (H MRS) to determine total creatine (tCr) concentrations will become increasingly prevalent, as the role of creatine (Cr) in supporting brain health gains interest. Methodological limitations and margins of error in repeated H MRS, which often surpass reported effects of supplementation, permeate existing literature. We examined the intra- and inter-session reliability and repeatability of H MRS for determining tCr concentrations across multiple brain regions (midbrain, visual cortex and frontal cortex).

Background & Aims: The aim of this study was to investigate the potential ergogenic effects of intra-session supplementation of highly branched cyclic dextrin (HBCD) on mechanical (number of repetitions completed and repetition velocity), metabolic (lactate concentration), and perceptual (gastrointestinal complaints and ratings of perceived exertion [RPE]) responses to resistance training.
Methods: This study used a randomized, double-blinded, placebo-controlled crossover study design. Thirty physically active individuals (15 men and 15 women) completed two experimental sessions that only differed in the supplement condition (placebo or HBCD).
Effects of Apnea-Induced Hypoxia on Hypoalgesia in Healthy Subjects.

Research Group Breatherapy, Centro Superior de Estudios Universitarios La Salle, Universidad Autónoma de Madrid, 28023 Madrid, Spain.
Introduction: Exercise-induced hypoalgesia is a phenomenon in which exercise bouts induce a reduction in pain sensitivity. Apnea training involves similar characteristics that could potentially induce hypoalgesia.
Objectives: The objectives of this study are to explore the effect of apnea training on hypoalgesia; assess the correlation between conditioned pain modulation (CPM) response and apnea-induced hypoalgesia; and examine the association between hypoalgesia with hypoxemia, and heart rate (HR) during apnea.

Running biomechanics have traditionally been analysed in laboratory settings, but this may not reflect natural running gait. Wearable technology has the potential to enable precise monitoring of running gait beyond the laboratory. This study aimed to evaluate the analytical validity and intra-session reliability of temporal running gait outcomes measured by the ViMove2 wearable system in healthy adults.
