Decreasing core body temperature during exercise may improve exercise tolerance, facilitate acclimatization, and prevent heat illness during summer training. We sought to evaluate the effectiveness of intermittent superficial cooling on thermoregulatory, cardiovascular, and perceptual responses during exercise in a hot humid environment. We used a randomized, counterbalanced, repeated measures ...

The present study determined whether 0.8g/kg bodyweight sago ingested before (Pre-Sago) or during (Dur-Sago) exercise under warm-humid conditions (30 ± 2°C, 78 ± 3 % RH; 20 km·h-1 frontal airflow) conferred a performance and/or physiological benefit compared to a control (Control) condition. Eight trained, male cyclists/triathletes (45 ± 4 y, VO2peak: 65 ± 10 ml·kg-1·min-1, peak aerobic power: ...

PURPOSE A recent laboratory study demonstrated that the ingestion of a cold/menthol beverage improved exercise performance in a hot and humid environment during 20 km of all-out cycling. Therefore, the aim of this study was to determine whether the ingestion of cold water/ice-slurry with menthol would improve performance in hot and humid outdoor conditions. METHODS Ten trained males completed...

Based on a great number of literatures, we established the database about the Chinese endemic seed plants and analyzed the compositions, growth form, distribution and angiosperm original families of them within three big natural areas and seven natural regions. The results indicate that the above characters of Chinese endemic plants take on relative rule at the different geographical scales. Am...

The timing and abruptness of the initiation and termination of the Early Holocene African Humid Period are subjects of ongoing debate, with direct consequences for our understanding of abrupt climate change, paleoenvironments, and early human cultural development. Here, we provide proxy evidence from the Horn of Africa region that documents abrupt transitions into and out of the African Humid P...

Analysis of genotype-by-environment interaction (GEI) is critical in the local potato breeding and selection programme to obtain information on performance genotypes for yield adaptability stability. The objective this study was assess marketable tuber 18 advanced clones compared commercial variety Spunta at four locations (Bigara, Réduit, St. Antoine Rivière du Poste), representative major soi...

this study was conducted using one hundred and eighty (180) day-old broiler chicks, of anak strain to assess the levels of inclusion of indomie waste meal as a substitute for maize at 0, 25, 50, 75 and 100%. the birds were randomly assigned to dietary treatments using completely randomized design (crd). each treatment contained 3 replicates and each replicate had 6 birds. the study lasted for e...

BACKGROUND Thermal safety standards for the use of chemical, biological, radiological, and nuclear (CBRN) ensembles have been established for various US occupations, but not for law enforcement personnel. OBJECTIVES We examined thermal strain levels of 30 male US law enforcement personnel who participated in CBRN field training in Arizona, Florida, and Massachusetts. METHODS Physiological r...

Data on litter production traits of does, involving 1120 litters, was collected over a 10-year period (1984 to 1994) and analyzed to estimate heritability and repeatability. Locally adapted does and bucks of predominantly New Zealand White breeding were involved. Traits studied were total litter size born and born alive, and litter size and weight at 21 days, 28 days (weaning) and 84 days (mark...

The study was conducted to determine the semen characteristics of three genotypes of Nigerian indigenous cocks. Thirty Six (36) local breeding cocks comprising of 12 frizzle, 12 normal and 12 naked neck selected randomly from the poultry breeding unit of the University of Port Harcourt Teaching and Research farm was used for this study. Semen were collected from them by abdominal massage and an...
