AI Article Synopsis

  • The study aimed to compare physiological responses (heart rate and blood lactate levels) of futsal players during the first half (1-H) and second half (2-H) while considering their on-court time during substitutions.
  • Results showed no significant differences in heart rate and blood lactate levels between the two halves, though there were variations in time spent in specific heart rate intensity zones.
  • The findings suggest that with proper substitutions and time management, players can maintain similar match intensity levels in both halves, providing valuable insights for coaches and future research.

Article Abstract

Physiological responses in futsal have not been studied together with temporal information about the players' stay on the court. The aim of this study was to compare heart rate (HR) and blood lactate concentration ([La]) responses between 1-H and 2-H considering the time of permanency of the players on the court at each substitution in a futsal match. HR was recorded during entire match and [La] was analyzed after each substitution of seven players. %HR (89.61 ± 2.31 vs. 88.03 ± 4.98 %HR) and [La] mean (8.46 ± 3.01 vs. 8.17 ± 2.91 mmol·L) did not differ between 1-H and 2-H (ES, trivial-small). Time in intensity zones of 50-100 %HR differed only in 60-70 %HR (ES, moderate). HR coefficient of variation throughout the match was low (7%) and among the four outfield players on the court (quartets, 5%). Substitutions (2 player's participation in each half), time of permanence on the court (7.15 ± 2.39 vs. 9.49 ± 3.80 min), ratio between time in- and out-ratio on the court (In:Outcourt = 1:1.30 ± 1:0.48 vs. 1:1.05 ± 1:0.55 min) also were similar between 1-H and 2-H (ES, moderate and small, respectively). Balancing the number of substitutions, and the In:Outcourt ratio of players in both halves of the match, playing lower time at 1-H, ~8 min for each participation in the match, made it possible to maintain intensity of the match in 2-H similar to the 1H. These results are a good guidance to coaches and for application in future studies.

Magnesium-containing molecules, including MgCH, MgCH, and MgCH, have been detected in the interstellar medium, largely facilitated by their high dipole moments. However, despite great efforts, MgCH species remain elusive. Given the challenges in obtaining experimental data for these molecules, theoretical studies play a crucial role in guiding their detection.

To investigate the effect of D-chiro inositol (DCI) supplementation on perinatal outcomes in pregnant women at high risk of gestational diabetes mellitus (GDM), we conducted a prospective, randomized, placebo-controlled study. Eligibility criteria included women aged ≥ 35 years old, with a pre-pregnancy body mass index ≥ 24 kg/m, having a family history of type 2 diabetes, having a history of GDM, polycystic ovary syndrome, or a history of delivering macrosomia infants. Participants who were recruited at a gestational age of 12-16 weeks, were randomly to receive either DCI 500 mg twice daily or to receive a placebo for 12 weeks.

Purpose: Dimethyl fumarate (DMF), the first-line oral therapy for relapsing-remitting multiple sclerosis, is rapidly metabolized into monomethyl fumarate. The DMF oral administration provokes gastrointestinal discomfort causing treatment withdrawal. The present study aimed to develop an innovative formulation for DMF nasal administration.

The semi-hydrogenation of alkynes into alkenes rather than alkanes is of great importance in the chemical industry, and palladium-based metallic catalysts are currently employed. Unfortunately, a fairly high cost and uncontrollable over-hydrogenation impeded the application of Pd-based catalysts on a large scale. Herein, a sandwich structure single atom Pd catalyst, Z@Pd@Z, was prepared impregnation exchange and epitaxial growth methods (Z stands for ZIF-8), in which Pd single atoms were stabilized by pyrrolic N in a zeolitic imidazolate framework (ZIF-8).
