Previous works have shown the potential of immersive technologies to make physical activities a more engaging experience. With encountered-type haptic feedback, users can perceive a more realistic sensation for exertion interaction in substitutions reality. Although substitutional reality has utilized physical environments, props, and devices to provide encountered-type haptic feedback, these cannot withstand the fierce force of humans and do not give feedback when users move around simultaneously, such as in combat sports. In this work, we present Hit Around, a substitutional moving robot for immersive and exertion interaction, in which the user can move and punch the virtual opponent and perceive encountered-type haptic feedback anywhere. We gathered insight into immersive exertion interaction from three exhibitions with iterative prototypes, then designed and implemented the hardware system and application. To understand the ability of mobility and weight loading, we conducted two technical evaluations and a laboratory experiment to validate the feasibility. Finally, a field deployment study explored the limitations and challenges of developing immersive exertion interaction with encountered-type haptics.

Caffeine (CAF) mouth rinsing has been considered a practical nutritional strategy among athletes. Recent studies indicate that this nutritional strategy's efficacy may depend on the athlete's prandial state. Therefore, the main aim of the current study is to determine the effect of CAF mouth rinsing on a battery of soccer-specific tests of soccer players in fasted (FST) or fed states (FED).

Purpose: This study examined the effects of cluster sets (CS) versus traditional sets (TRAD) on performance and perceptual responses during pneumatic chest press (CP) and leg press (LP). Exercise-specific differences and the influence of sex and strength were also explored.
Methods: Forty-seven recreationally resistance-trained young adults (23 male and 24 female) performed CP and LP at 70% 1-repetition maximum in either CS (4 × [2 × 5], 30-s intraset rest, 150 s between sets) or TRAD (4 × 10, 180-s rest between sets) in randomized order.

Background: Personalized Interactive Music Systems (PIMSs) are emerging as promising devices for enhancing physical activity and exercise outcomes. By leveraging real-time data and adaptive technologies, PIMSs align musical features, such as tempo and genre, with users' physical activity patterns, including frequency and intensity, enhancing their overall experience.
Objective: This exploratory systematic review and meta-analysis evaluates the effectiveness of PIMSs across physical, psychophysical, and affective domains.

Background: In patients with Fontan circulation, veno-venous collaterals (VVCs) are associated with complications such as cyanosis, ventricular overload, erythrocytosis, and paradoxical embolism. However, VVCs may play a compensatory role in the attenuation of central venous pressure elevation. In this study, we evaluated the impact of VVCs on Fontan circulation by analysing the relationship between peak peripheral venous pressure (PPVP) and peak oxygen uptake (PVO) during exercise.

: The therapeutic response in Graves' Disease (GD) remains largely unpredictable. Patients often experience persistent symptoms that are poorly correlated with thyroid hormone levels, an undefined treatment duration, and the need for long-term or definitive therapies. Based on the nuclear antagonistic properties of L-carnitine (LCT) on thyroid hormone action and the immunomodulatory role of selenium (Se), we aimed to assess the impact of adding a combined LCT and Se supplement to standard methimazole (MMI) therapy on the biochemical profile and quality of life (QoL) of patients with overt GD.
