Interval exercise has been used as an alternative modality to continuous exercise in patients with various conditions. Although interval exercise can improve health status, it may also exert deleterious effects. Few data are available on differences in psychoneuroimmunological response to high-intensity interval exercise, and it is not known whether males and females differ in their responses to a similar physical stress task. The aim of this study was to evaluate the differences between the psychoneuroimmunological responses of healthy active males and females to a high-intensity interval exercise protocol. Fifty healthy active subjects (25 females) underwent 2 exercise protocol sessions at least 2 weeks apart and at the same time of the day. The first session familiarized participants with the protocol. In the second, after a baseline measurement, subjects performed an exercise protocol with a standardized warm-up followed by three 30-s Wingate tests and an active recovery period. Baseline and postintervention data were gathered on the following: Holter electrocardiogram recordings (standard deviation of normal-to-normal interval [SDNN], square root of mean squared differences of successive NN intervals [RMSSD]); heart rate variability (HRV) index; salivary total protein and immunoglobulin A levels; pressure pain thresholds in masseter and upper trapezius muscles; and profile of mood states. After the exercise protocol, mood disturbance was significantly greater in the males than in the females, while the salivary immunoglobulin A level relative to total proteins was significantly lower in the males. These results suggest that high-intensity interval exercise induces a worse psychoneuroimmunological state in males than in females.
This paper aims to analyze the non-native use of Spanish verbs of different aspectual classes by Mandarin Chinese speakers performing oral narrative tasks. In this work, we adopt Vendler’s (Vendler, Zeno. 1967. Linguistics in philosophy. Ithaca: Cornell University Press) lexical-aspect classification (states, activities, accomplishments, and achievements), and we analyze the Spanish L2 acquisition of these categories by sinophones both at the level of the lexical form acquisition and at the semantic level. Based on data obtained from two oral narrative tasks elicited from storyboard vignettes performed by three groups of learners of L2/L3 Spanish (ranging from B1 to C1 levels of the CEFR), this work supports Jiang’s (Jiang, Nan. 2000. Lexical development and representation in a second language. Applied Linguistics 21(1). 47–77) L2 lexical acquisition pattern at the lexical form level, as our sinophone learners show a similar pattern to the one observed in native speakers in the use of aspectual class of compositional form (accomplishments)and aspectual classes of individual form (states, activities and achievements). However, at the lexical semantic level, we found that, besides L2 proficiency, the properties of lexical semantics may also impact learners’ L2 lexical processing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
