There is scant information available about the blood flow of the pulmonary artery in avian cardiology. In human medicine, the shape of the Doppler sonographic blood flow profile of the pulmonary artery can be used to access the pressure conditions of the right heart. With this background, this study focused on the examination of the acceleration and deceleration phase of the pulsed-wave Doppler flow profile of the pulmonary artery of healthy racing pigeons.

Methylsulfonylmethane (MSM), also known as dimethyl sulfone, is a naturally occurring sulphur-containing compound that can be found in plants, animals and humans. MSM can also be a metabolite of dimethyl sulfoxide (DMSO). Due to their anti-inflammatory and analgesic effects, both MSM and DMSO are prohibited substances in horseracing.

Purpose: Alpine skiing races are physically demanding events characterized by numerous repeated near-maximal activations of the lower limb muscles. Although this type of task is known to induce neuromuscular fatigue, electromyographic activity (EMG) adaptations after repeated maximal-intensity skiing have not been previously investigated.
Methods: Six skiers completed a 6-turns section with (FAT) and without performing 30 giant slalom (GS) turns (CONT).

Study Question: To what extent is male physical activity (PA) associated with fecundability (per-cycle probability of conception)?
Summary Answer: Preconception levels of vigorous, moderate, or total PA were not consistently associated with fecundability across Danish and North American cohorts, but there was suggestive evidence that bicycling with a 'soft, comfort seat' was associated with reduced fecundability in both cohorts, especially among males with greater BMI.
What Is Known Already: Among males, some studies indicate that moderate PA might improve fertility, whereas vigorous PA, especially bicycling, might be detrimental.
Study Design, Size, Duration: We assessed the association between male PA and fecundability among couples participating in two preconception cohort studies: SnartForaeldre.
