Androgens and athletic performance of elite female athletes

Current Opinion in Endocrinology, Diabetes & Obesity, 2017
Purpose of review During the last decades androgens have been used illicitly by athletes of both genders. Because of some obvious ethical limitations, mechanisms underlying the performance-enhancing effects of these hormone or drugs, as well as the magnitude of their effects, have been poorly addressed.

Aerobic performance capacity in athletes

European Journal of Applied Physiology and Occupational Physiology, 1978
Maximal oxygen uptake (max VO2) in leg and arm work, succinate dehydrogenase activity (SDH) and percentage of slow twitch fibers (%ST fibers) in M. vastus lateralis (VL), M. gastrocnemius c.l. (GL) and M. deltoideus (D) were studied in 89 athletes practising 11 different sport events.

Anaerobic Performance Capacity in Athletes

Acta Physiologica Scandinavica, 1977
AbstractAnaerobic performance characteristics of the whole body and at muscle tissue level were studied in 89 athletes and 31 reference subjects. The main parameters were vertical velocity during running up the stairs, maximal isometric force of leg extensor muscles, blood lactate concentration after maximal treadmill running test, percentage of fast ...

Circadian rhythms and athletic performance

Medicine & Science in Sports & Exercise, 1985
Daily or circadian rhythmical oscillations occur in several physiological and behavioral functions that contribute to athletic performance. These functions include resting levels of sensory motor, perceptual, and cognitive performance and several neuromuscular, behavioral, cardiovascular, and metabolic variables.

Genetic Determinants of Athletic Performance

Recent Patents on DNA & Gene Sequences, 2012
An extraordinary revolution in medical research has taken place over the past decade, enabled by the completion of the first human genome sequence in 2001. The Human Genome Project (HGP) has resulted in the 6 billion letter reference human genome sequence and the ultra-high throughput technologies used by medical researchers to identify correlations ...

Age and performance in athletics

Internationale Zeitschrift f�r Angewandte Physiologie Einschliesslich Arbeitsphysiologie, 1955
The study presents the age distribution of the best Finnish sportsmen in 20 track and field events, in ski sports, ball games and competitive lumber work. The results are shown graphically and in tables, in which the significance of the differences of the mean age in the various sports is also calculated.

Animal athletes: a performance review

Veterinary Record, 2012
Major sporting events such as the Olympic Games highlight extraordinary human athletic achievements, performed by the extreme physical outliers of our species. However, there is a range of animal performance that goes far beyond these, both in the wild and in selectively bred ‘sports animals’ such as the racehorse, racing camel, greyhound, sled‐dog and

Nutritional Conditioning and Athletic Performance

Primary Care: Clinics in Office Practice, 1982
Incorporating nutritional conditioning into an athletic program can contribute significantly to the development and maintenance of physical performance. However, the principles of good nutrition must be practiced consistently throughout the training period, not only prior to athletic events. The article offers advice on glycogen loading, pre-game meals,

Psychoactive Drugs and Athletic Performance

The Physician and Sportsmedicine, 1997
Some psychoactive drugs have actual performance-enhancing side effects. However, many actually decrease performance, primarily because of adverse cardiovascular effects and impaired judgment. Athletes and nonathletes alike may be knowingly or unknowingly exposed to psychoactive substances if they use over-the-counter, recreational, or prescription ...
