Effect of Methylxanthines on Lactational Performance of Rats
Annals of Nutrition and Metabolism, 1990Caffeine, theophylline and theobromine are commonly consumed methylxanthines. There are conflicting reports that methylxanthines may adversely affect the outcome of pregnancy. The effects of methylxanthines on lactational performance were investigated by administration of pure alkaloids via drinking water to Wistar albino rats throughout pregnancy and ...

EFFECT OF LACTATE CONSUMPTION ON EXERCISE PERFORMANCE.
Medicine & Science in Sports & Exercise, 1995Maintenance of plasma glucose is important in endurance performance. Gluconeogenesis or carbohydrate ingestion maintain glucose after hepatic glycogen depletion. Lactate may also serve as a gluconeogenic precursor as well as a blood buffer.To determine if an 8% carbohydrate (CHO) sports drink with and without a 2% lactate (L) solution increased ...

Evaluation of lactational performance of Navajo women
The American Journal of Clinical Nutrition, 1981The effect of suboptimal maternal nutrition on lactational performance of 23 Navajo women was studied in terms of milk volume, milk composition, and infant growth. The mean milk volume produced by 10 Navajo women was 634 +/- 113 mg/24 h after approximately 1 month of lactation.

Maternal Nutrition and Lactation Performance
Journal of Tropical Pediatrics, 1972Prolonged breastfeeding has been reported to protect the child from grossly defective weaning foods used in most developing countries. Even grossly malnourished mothers have been known to produced enough milk to keep their children alive. Hytten and Thompson reported that there is no evidence that maternal nutrition affect lactation.

Maximal lactate-steady-state independent of performance
Medicine & Science in Sports & Exercise, 2000The maximal lactate steady state (MLSS) corresponds to the highest workload that can be maintained over time without a continual blood lactate accumulation. MLSS and MLSS intensity have been speculated to depend on performance. Experimental proof of this hypothesis is missing.33 male subjects (age: 23.7 +/- 5.5 yr, height: 181.2 +/- 5.3 cm, body mass ...

Assessment of Lactation Performance in Women
1986Successful reproduction in animals requires an adequate supply of food for the young to grow and develop into an adult. In many species of birds and reptiles, the adults can thrive in environments which lack suitable foods for their young. Thus vertebrates which bring food to the nest can only breed successfully if they can find sufficient quantities ...

A note on the lactation performance of twin-bearing cows
Journal of Dairy Research, 1983SummarySeven pairs of cows were chosen at parturition. In each pair, 1 member had had a twin pregnancy (T) and the other was a comparable cow with a single calf pregnancy (S). All cows were offered the same amount of feed over the first 28 weeks of lactation. In early lactation, intakes were equal; in mid-lactation the T group ate more.

Subjective Assessment of Lactational Performance in Gambian Mothers
Journal of Tropical Pediatrics, 1985This study examines the ability of a group of breastfeeding Gambian mothers to assess their own lactational performance. 113 mothers at different stages of lactation entered the study. They were all already participating in a longer ongoing study of lactation with regular monthly estimations of their breast milk outputs by test weighing.

Plasma lactate accumulation and distance running performance
Medicine & Science in Sports & Exercise, 1979Laboratory and field assessments were made on eighteen male distance runners. Performance data were obtained for distances of 3.2, 9.7, 15, 19.3 km (n = 18) and the marathon (n = 13). Muscle fiber composition expressed as percent of slow twitch fibers (%ST), maximal oxygen consumption (Vo2max), running economy (Vo2 for a treadmill velocity of 268 m/min)

Lactational Performance and Milk Composition in Relation to Duration of Pregnancy and Lactation
1986The dynamic changes that occur in milk composition associated with duration of lactation have been recognized for over a century as documented in several early publications some dating back to 1874 (1–3). In the mid 1900s Macy (4) reviewed 1500 publications on milk composition from many countries and selected 268 papers based on “the characteristics of
