Is the Energy Cost of Rowing a Determinant Factor of Performance in Elite Oarsmen?

In elite oarsmen, the rowing ergometer is a valuable tool for both training and studying rowing performance determinants. However, the energy cost of rowing, often reported as a determinant of performance, has never been described for ergometer rowing. Therefore, this study aimed to characterize the energy cost of ergometer rowing (ECR) in elite oarsmen, its contribution to 2,000 m performance, and its determinants.

Preventive measures for the critical postexercise period in sickle cell trait and disease.

The immediate postexercise/physical activity period is critical for sickle cell trait (SCT) carriers and disease (SCD) patients. Exercise-related blood acidosis is known to trigger the cascade of HbS deoxygenation and polymerization, leading to red blood cell sickling and subsequent complications. Unfortunately, two facts worsen exercise-related blood acidosis during the initial postexercise period: First, blood lactate and H concentrations continue to increase for several minutes after exercise completion, exacerbating blood acidosis.

Local vibration training improves the recovery of quadriceps strength in early rehabilitation after anterior cruciate ligament reconstruction: A feasibility randomised controlled trial.

Background: After anterior cruciate ligament reconstruction (ACLR), quadriceps strength must be maximised as early as possible.

Objectives: We tested whether local vibration training (LVT) during the early post-ACLR period (i.e.

[Comparison of four formulas of adjusting QT interval for the heart rate in young elite athletes].

Purpose: Sudden cardiac death in young athlete is always tragic. Some international guidelines recommend the realization of an electrocardiogram before practicing competitive sports to carry out the risk of sudden cardiac death due to genetic cardiopathy like QT long syndrome. Unfortunately, the diagnosis can be difficult because intensive sport can increase the QT interval over normal recognized values for sedentary people.
