Publikováno v: The Physician and sportsmedicine. 17(12)

In brief: Using several hematologic indexes, researchers examined the iron status of 50 ultraendurance athletes participating in the 1988 Ironman Triathlon in Hawaii. Fifteen (30%) of the 50 triathletes had at least one suboptimal iron index: Two exh

Autor: R H Laird, W. Douglas B. Hiller, Pamela S. Douglas, M. L. O'toole

Publikováno v: Clinical Journal of Sport Medicine. 5:116-122

Thirty competitors in the Hawaii Ironman Triathlon were prospectively studied to determine whether fluid and electrolyte disturbances were causes for seeking race-day medical care. Athlete weights were significantly (p < 0.0001) decreased during the

Use of heart rate monitors by endurance athletes: lessons from triathletes

Autor: M L, O'Toole, P S, Douglas, W D, Hiller

Publikováno v: The Journal of sports medicine and physical fitness. 38(3)

Heart rate monitors are commonly used but little is documented about their use. We have reviewed the available literature and supplemented it with data regarding heart rate responses of a large number of highly trained athletes during cycle ergometer

Autor: J W, Griffin, R E, Tooms, R, vander Zwaag, T E, Bertorini, M L, O'Toole

Publikováno v: Medicine and science in sports and exercise. 25(8)

Maximal voluntary eccentric (ECC) and concentric (CON) capacity of knee and elbow muscle groups was investigated in healthy untrained men (N = 40) and women (N = 50), 21-67 yr of age. Purposes of the study were to describe torque-velocity and ECC-CON
