Lactate, Oxygen Uptake, and Cycling Performance in Triathletes
International Journal of Sports Medicine, 1989To assess the relationship of exercise test variables to each other and to bike race times in an ultra-distance triathlon, we studied 24 participants (14 men, 10 women) in the 1985 Hawaii Ironman Triathlon, using a graded, maximal cycle ergometer test with gas exchange and blood lactate (LA) measurements at each work load.

Lactate exchange and removal abilities in rowing performance
Medicine & Science in Sports & Exercise, 1997The relationships between individual performance and lactate exchange and removal abilities were studies in 12 male rowers all subjected to three measurements on a rowing ergometer. An incremental exercise carried out to determine the maximal oxygen uptake (VO2max) and the corresponding maximal aerobic power (Pamax), a 2500-m all-out test where the ...

Lactational performance in relation to energy intake in the baboon
The American Journal of Clinical Nutrition, 1985The relationship between energy intake and lactational performance in the baboon was investigated by determining energy intake, milk output and energy balance in animals fed ad libitum during a nonreproductive phase and during lactation, or fed 80% or 60% of ad libitum intake during lactation. No evidence was found for an increased efficiency of energy

Lactate and glucose minimum speeds and running performance
Journal of Science and Medicine in Sport, 2004This study aimed to analyse the validity of glucose minimum speed (GMS) for lactate minimum speed (LMS) assessment during running and their relationship to endurance performance. Eight male trained runners (28.7 +/- 9.0 years) volunteered to take part in this study and underwent an official 10-km road race and a track lactate minimum test (LMT) (0.5-km

Sports Medicine, 1986
The blood lactate response to exercise has interested physiologists for over fifty years, but has more recently become as routine a variable to measure in many exercise laboratories as is heart rate. This rising popularity is probably due to: the ease of sampling and improved accuracy afforded by recently developed micro-assay methods and/or automated ...

SUMMARY The effects of extending lactation up to 48 days on serum thyroxine (T4), and its relationship to lactational performance, were studied with rats fed a ration containing 1·0 μg I−/g of feed. The effects of chronic administration of 9α-fluoroprednisolone acetate on serum T4 during prolonged lactation were also determined. Lactation was prolonged

Lactation performance of rural Mesoamerindians.
European journal of clinical nutrition, 1992Anthropometry, body composition and dietary intake of 30 lactating Otomi Indians of Capulhuac, Mexico, were studied to identify maternal factors which potentially limit lactation and thereby infant growth. Human milk production, milk composition, and maternal dietary intake, body weight, skinfold thicknesses, and body composition were measured at 4 and

Effect of methylxanthines on lactational performance [PDF]
, 1987 Caffeine, theophylline and theobromine constitute a group of purine alkaloids designated methylxanthines. These are consumed in coffee, tea, chocolates, cola beverages and some patent drugs, presenting diverse metabolic actions such as stimulation of the central nervous system, diuresis and increased metabolic rate.

Is Maternal Obesity a Cause of Poor Lactation Performance?
Nutrition Reviews, 2005Several investigators have reported a relationship between maternal obesity and low rates of initiation and duration of breast-feeding. Recent research findings suggest that poor infant feeding behavior and reduced hormonal responses in the early postpartum period result in delayed lactogenesis and early cessation of breast-feeding among overweight ...
