The thorny issue of drug use by athletes, especially the regulation of performance-enhancing drugs, was also addressed.
This spring, federal legislation was introduced calling for regulation of performance-enhancing drugs and medications as well as stiff penalties for offenders.
Nearly three years after a Congressional subcommittee heard testimony about how thoroughbred racing had become "chemical warfare," bipartisan legislation calling for federal regulation of performance-enhancing drugs and medications will be introduced next week.
With bipartisan legislation calling for federal regulation of performance-enhancing drugs and medications as well as stiff penalties for offenders, horse racing's stakeholders are taking a hard look at their medication rules.
With bipartisan legislation awaiting a vote and calling for federal regulation of performance-enhancing drugs in horses and stiff penalties, including a permanent ban, for trainers whose horses test positive for drugs, the definition of what exactly is a fast (or slow) horse may be in transition.
It has been established that PPAR δ plays an important role in the regulation of cardiac performance [ 17– 17].
Our results indicate that sphingosine and sphinganine are unlikely to play a significant role in skeletal muscle fatigue or regulation of muscle performance in humans.
The regulation of plant performance by earthworms has been documented in a number of studies showing that earthworms can alter plant nitrogen content by enhancing nitrogen availability in the soil [ 37]–[ 39].
We hypothesized that cortisol might play an important role in this mechanism as cortisol, implicated in the regulation of memory performance, can be brought out of balance by stressors like MDMA.
However, the field of muscle intracrinology is still in its infancy warranting further studies representing both genders with different age groups and physical activity levels to provide a consensus on the role and function of intracrine hormones in the regulation of muscle performance.
Chemosensitive glomus cells in the CB respond to changes in arterial oxygen, carbon dioxide and acidity, and increase the intracellular calcium ([Ca2+]i) for the release of neurotransmitters including catecholamines and ATP to activate the chemoreflex for the regulation of cardiorespiratory performance during hypoxia (Gonzalez et al. 1994; Lahiri et al. 2001).
