COVID-19 and physical activity in sedentary individuals: differences in metabolic, cardiovascular, and respiratory responses during aerobic exercise performed with and without a surgical face masks.

Background: The Coronavirus-19 (COVID-19) impairs metabolic, cardiovascular, and pulmonary functions in human metabolism, and wearing face masks is recommended for the prevention of contracting or exposing others to cardio-respiratory infections. Since the effect of wearing a surgical face mask (SFM) on cardiopulmonary exercise capacity has not been systematically reported we aimed to determine the effects of wearing SFM during an incremental walking test on metabolic, cardiovascular, and pulmonary gas exchange responses in sedentary individuals.

Methods: The evaluations were performed using a repeated measures study design.

Monitoring of pre-competition dehydration- induced skeletal muscle damage and inflammation levels among elite wrestlers.

Background: Weight loss practice before competitions is a common method in weight sports.

Objective: The current study aimed to monitor Plasma Osmolarity (POsm), skeletal muscle damage and inflammation levels induced by pre-competition dehydration among elite wrestlers.

Methods: Twenty-four male elite wrestlers participated in the study.

Virulence Factors in Staphylococci Isolated From Nasal Cavities of Footballers.

Aim: This study aimed to investigate the rate of Panton-Valentine Leukocidin producing Staphylococcus aureus and methicillin (mecA) and slime (icaA/icaD) genes in staphylococcal strains isolated from nasal cavities of footballers.

Materials And Methods: Nasal swab samples were taken from each footballers and a healthy control group for the isolation of staphylococcal strains. The polymerase chain reaction technique was used to determine Panton-Valentine Leukocidin, mecA and icaA/icaD genes in staphylococcal isolates.
