Performance of Hemochron ACT-LR and ACT+ Test Cuvettes in Monitoring Low to Moderate Heparin Concentrations: An In Vitro Study.

Objectives: According to the manufacturer, the Hemochron ACT-LR cuvette is designated for heparin concentrations of 0 to 2.5 IU/mL, while the optimal concentration range for the ACT+ cartridge is 1 to 6 IU/mL. We hypothesized that at low to moderate heparin concentrations, the ACT-LR is more reliable than the ACT+.

Changes in female football players' in-season training load, intensity and physical performance: training progression matters more than accumulated load.

Introduction: This observational study investigated: (1) potential changes in female football players' in-season training load, intensity and physical performance, and (2) if in-season accumulated training load, intensity, or their progression are associated to changes in physical performance.

Methods: Thirty-five national level female players (∼21 years,  = 35) from three top-teams of the Finnish national league participated. Players performed tests at the beginning and at the end of the 27-week in-season.

Children's active school transportation: an international scoping review of psychosocial factors.

Background: Over the last decades, the prevalence of AST has decreased significantly. Barriers to active school transport (AST) have been extensively examined in the literature, while psychosocial factors that facilitate AST have received less attention. To our best knowledge, there are currently no reviews on this subject.

Average demands and most demanding passages of national-level female soccer matches: do small- and large-sided games replicate match demands?

Introduction: This study aims to (1) determine the average and most demanding passage (MDP) load of national-level female soccer matches and (2) evaluate the relationship between average and MDP load during small-sided games (SSGs), large-sided games (LSGs), and matches.

Methods: A total of 37 national-level female soccer players from a single club senior team and the U18 team participated. The average and 1-, 3-, and 5-min MDP external (total, high-speed, and very-high-speed running distances, acceleration and deceleration distances, average metabolic power, and high-metabolic load distance) and internal loads (average heart rate, rate of perceived exertion) of the 29 league matches, ten 4 vs.

Physical qualities and body composition predictors of running performance in national level women's official soccer matches.

The purpose of the study was to (1) determine match running performance, anthropometry and various physical qualities of national level women soccer players and (2) identify key physical qualities and anthropometric predictors of match running profile during a competitive season. Twenty-five national level Finnish soccer players participated in the study. Players performed countermovement jump, loaded squat jumps, 30-meter sprint, maximum isokinetic knee flexor and extensor contractions, an incremental treadmill test and underwent body composition assessment in the lab.
