Effect of High Intensity Interval Training Under Mask on Forced Vital Capacity in Football Players.

The purpose of the study was to investigate the effect of high interval training (HIIT) under mask on forced vital capacity in football players. Fourteen male football players (age 20 ± 2 years) were randomized into the without mask group (CON) or with the 2 difference mask groups [Surgical mask (SM), FFP2 mask (FM)]. HIIT program were implemented six movements in each session three times per week.

Cardiac Biomarkers Following Marathon Running: Is Running Time a Factor for Biomarker Change?

Purpose: Plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) and cardiac troponin T levels show a transient increase after marathon running. The aim of this study was to investigate whether running duration influences the patterns of changes in cardiac biomarkers.

Methods: Twenty participants with fast and slow finishing times were included in the study.

Energy metabolism, liver and kidney function in adolescent marathon runners.

Background: To study parameters of energy metabolism, liver and kidney function in adolescent runners completing a standard 42·2-km marathon run.

Design: Observational field study.

Materials And Methods: Fifty adolescents (30 healthy males and 20 healthy females) aged between 13 and 17 years participated in the study.

Plasma electrolyte and hematological changes after marathon running in adolescents.

Purpose: The objective of this research is to study plasma electrolyte and hematological changes in adolescent runners completing a standard 42.2-km marathon run.

Methods: Fifty adolescents (30 healthy males and 20 healthy females) between ages 13 and 17 yr participated in the study.

Cardiac troponins in young marathon runners.

Cardiac troponin increases are common in adult marathon finishers. However, data on troponin values for young marathon runners are scarce. Forty young runners (20 healthy male and 20 female) 13 to 17 years old participated in this study.
