Mechanical efficiency in rowing

Abstract

Five university oarsmen participated in a determination of mechanical efficiency when rowing in a tank. In the tank, water was circulated at 3 m X s-1 by a motor driven pump. The subjects rowed with the stepwise incremental loading, in which the intensity increased by 10% of the maximum force of rowing (maxFc) every 2 min. Power (WO) was calculated from the force applied to the oarlock pin (FC) and its angular displacement (theta H). Oxygen uptake and heart rate were measured every 30 s during rowing. Anaerobic threshold (AT) was determined from expired gas variables by Wasserman's method. AT of oarsmen was 74.6 +/- 6.01% as a percentage of VO2max. As the displacement of the handgrip in the stroke was independent of WO, the increment of WO was caused by the increase of both FC and stroke frequency. Gross efficiency without base-line correction (GE) increased with FC with low intensities of rowing. In the region of 124-182 W of WO GE was almost constant at 17.5%. Efficiency was 19.8 +/- 1.4%, with resting metabolism as base-line correction (net efficiency), and 27.5 +/- 2.9% when using the unloaded rowing as the base-line correction (work efficiency), and 22.8 +/- 2.2% when calculating the work rate as the base-line correction (...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
