Physiological Correlates to In-race Paratriathlon Cycling Performance
International Journal of Sports Medicine, 2020AbstractThe purpose was to determine the physiological correlates to cycling performance within a competitive paratriathlon. Five wheelchair user and ten ambulant paratriathletes undertook laboratory-based testing to determine their: peak rate of oxygen uptake; blood lactate- and ventilatory ...

Physiology, Power Output, and Racing Strategy of a Race Across America Finisher
Medicine & Science in Sports & Exercise, 2011The Race Across America, a 4800-km nonstop cycle race, is one of the most demanding endurance sports events. We display the racing strategy, power output, HR, hormonal levels, and inflammatory markers of an athlete before and during the race, which he completed in 10 d 23 h.The athlete showed physiological characteristics of a well-trained (nonelite ...

Designation of Physiological Races of Plant Pathogens
Nature, 1970THE physiological races of most plant pathogens have been designated on an historical basis, being numbered in order of their isolation and identification. This has little intrinsic merit, because the order in which they are isolated depends largely on their relative frequencies within the population, and these frequencies vary with changes in the host

Physiological Demands of Flat Horse Racing Jockeys
Journal of Strength and Conditioning Research, 2015The physiological demands of jockeys during competition remain largely unknown, thereby creating challenges when attempting to prescribe sport-specific nutrition and training guidelines. The purpose of this study was to evaluate the physiological demands and energy requirements of jockeys during flat racing. Oxygen uptake (V[Combining Dot Above]O2) and

The great transatlantic race: physiologic and otoneurologic considerations
The Journal of Laryngology & OtologyAbstractBackgroundIn the era of the competition for the first transatlantic flight at the beginning of the nineteenth century, numerous accidents occurred. Whereas engine failure, bad weather and navigational problems are usually held responsible, the human factor has hardly been addressed.MethodsIn view of current insights, an inventory was made of ...

Sports Medicine and the Physiology of Wheelchair Marathon Racing
Orthopedic Clinics of North America, 1980In the past three decades, wheelchair sports have become an international reality. Disabled athletes are exercising their right to accept the challenges and risks taken by able-bodied athletes. Marathon racing over a 26-mile, 385-yard course is the latest and most strenuous of the wheelchair athletic events.

Physiological Correlates of Female Road Racing Performance
Research Quarterly for Exercise and Sport, 1981Abstract The purpose of this study was to determine the relationship between female distance running performance on a 10 km road race and body composition, maximal aerobic power ([Vdot]O2 max ), running economy (steady-state [Vdot]O2 at standardized speeds), and the fractional utilization of [Vdot]O2max at submaximal speeds (% [Vdot]O2max ).

Physiologic races of Phytophthora fragariae
Annals of Applied Biology, 1962SUMMARYPathogenicity tests with forty‐nine isolates of Phytophthora fragariae, cause of red core disease of strawberry, using the strawberry varieties Huxley, Perle de Prague, Climax, Talisman, Aberdeen and Cambridge Vigour, revealed the existence of twelve physiological races of the fungus on the basis of a pathogenic or non‐pathogenic reaction ...

Physiological Races of Puccinia polysora Underw.
Nature, 1955OUR early studies on the resistance of maize seedlings to this rust in East Africa led to the hypothesis that a dominant major gene controls the hypersensitive type of resistance1. During the past two years, we have bred many lines of maize that are pure for this gene, by selfing resistant plants selected from Central American types and by selfing ...

Physiological races ofExserohilum turcicum in Israel
Phytoparasitica, 1989A set of differentials of corn plants(Zea mays L.) containing Ht1, Ht2, Ht3 or HtN genes was used to identify races ofExserohilum turcicum in Israel. Plants were inoculated with 14 isolates ofE. turcicum collected from various regions in Israel (from Ayyelet HaShahar in the north to Sa’ad in the south).
