This study analysed the time course of the global metabolic acute response after resistance exercise (RE), with the use of proton nuclear magnetic resonance (¹H NMR) spectroscopy. Ten young healthy males performed 4 sets of 10 repetitions at 70% of one-repetition maximum in the leg press and knee extension exercises and had the serum metabolome assessed at 5, 15, 30 and 60 min post-RE. Measurements were also performed 1 h earlier and immediately before the exercises, as an attempt to characterise each participant’s serum metabolome at rest. One-way ANOVA was applied and the significance level was set at P ≤ 0.05. RE promoted an increase in 2-hydroxybutyrate, 2-oxoisocaproate, 3-hydroxyisobutyrate, alanine, hypoxanthine, lactate, pyruvate and succinate concentrations. However, isoleucine, leucine, lysine, ornithine and valine had their concentrations decreased post-RE compared with at rest. This is the first study to show significant changes in serum concentration of metabolites such as 2-oxoisocaproate, 2-hydroxybutyrate, 3-hydroxyisobutyrate, lysine, hypoxanthine and pyruvate post-RE, attesting metabolomics as an interesting approach to advance in the understanding of global RE-induced metabolic changes. Moreover, the present data could influence the time point of blood collection in the future studies that aims to investigate metabolism and exercise.  相似文献

Reading prosody development in Spanish children     

Marta Álvarez-Cañizo  Paz Suárez-Coalla  Fernando Cuetos 《Reading and writing》2018,31(1):35-52

Reading prosody is considered one of the essential markers of reading fluency, alongside accuracy and speed. The aim of our study was to investigate how development of reading prosody in Spanish children varies with sentence type and length. We compared primary school children from the third and fifth grades with an adult sample. Participants were recorded reading aloud a narrative text including short and long declarative, exclamatory and interrogative sentences. Recordings were analysed using Praat software to measure several prosodic features (i.e., pauses, duration, pitch and intensity). We found that third-grade children had not yet developed an adult-like prosody: they made more pauses, had a flatter melodic contour and had difficulty anticipating sentence structure. Fifth-graders displayed some features of adult prosody. Both length and type of sentence influenced the expressiveness of reading in the three groups. We conclude that reading expressiveness is closely related to reading experience and develops in a similar way to decoding and reading speed.  相似文献   

Presentation of a flashing light following one-trial fear conditioning enhances retention     

Rita Y. Emmerson  Terry L. DeVietti 《Learning & behavior》1982,10(3):325-329

Rats exposed for 60 sec to a flashing light stimulus following one-trial fear conditioning showed enhanced retention performance relative to controls not exposed to the flashing light. The results of a second experiment demonstrated a time-dependent gradient of the enhancement effect. In view of additional data indicating that the flashing light is not aversive, these results suggest that the presentation of an exteroceptive stimulus can influence memory processing.  相似文献
