Diet, Haemoglobin, and Blood Pressures of Olympic Athletes

Causal analysis of Distance Running Performance

“…Haemoglobin recorded here was slightly below the value for "normal" individuals (Wintrobe, 1930) but closer to the 16.0 mgo found for athletes (Berry et al, 1949) and the internationally accepted "normal" value (15.6 mg%) given by Shephard (1969). However, Brown and Goodall (1946) found a 6.3% daily variation in-131 haemoglobin and stated that variations in the distribution of RBC's throughout the vascular system seemed to be the most probably cause of fluctuation.…”

“…Wintrobe (1930) indicated the haemoglobin level of "'normal" individuals was 16.21 mgo. Athletes have been shown to have approximately the same value (Robinson, Edwards, and Dill, 1937;Berry et al, 1949), although researchers have indicated both decreases (Bass et al, 1958) and increases (Kjellberg, Rudhe, and ). The latter may be a factor limiting maximal performance.…”

Dietary Intake of Athletes Seeking Nutrition Advice at a Major International Competition

“…Only one study has investigated the types of diets (regimens) that are followed by these athletes [24]. Apart from records collected in 1949 [25] and 1964 [26], the most recent and relevant data on dietary intake in this type of environment was collected at the Sydney 2000 OG [23]. This data on apparent consumption within the dining hall suggested that athletes were consuming on average 592 g of carbohydrate (46% TE and on average 7–10 g/kg BM), 202 g (16% TE) of protein and 197 g (35% TE) of fat daily [23], however, no data on individual consumption was collected.…”
