Lactate and phosphocreatine concentrations were monitored in the white muscle of rainbow trout Oncorhynchus mykiss following swimming at 70, 80 and 100 % of critical swimming speed (Ucrit) using 31P-nuclear magnetic resonance (NMR) spectroscopy. Lactate was detected following swimming at all speeds, but its concentration was greatest following swimming at 80 and 100 %Ucrit. Phosphocreatine stor...

OBJECTIVE To investigate the causes of child drowning and determine the need for changes in the legislation as well as improvements to the inspection and enforcement of current legislation related to barriers surrounding private swimming pools. METHODS There were 3 stages to the study: a retrospective review of coroner's data, an audit of swimming pool inspections, and in-depth interviews wit...

this study aimed at application of optimization standards of water consumption in swimming pools of urmia. for this purpose, all 13 swimming pools of urmia were studied as the statistical sample of the study. the data were collected through a questionnaire and a checklist obtained based on the standards of standard institution and industrial studies (1388) and the office of national legislation...

background: infections are readily transmitted as a result of bacterial contamination of swimming pools. therefore, hygiene and preventing the contamination of swimming pools is of particular importance. the objective of this study was to determine the amount of bacterial contamination in indoor pools of yazd in 2013. methods: in this descriptive and analytical study, all indoor swimming pools ...

objective: pimpinella anisum (p. anisum) has different pharmacological properties such as anticonvulsant, analgesic, tranquilizer, antidepressant and anti-anxiety effects. in this study the antidepressant-like effect of aqueous and ethanolic extracts of p. anisum fruit in mice was investigated. materials and methods: forced swimming test (fst) and tail suspension test (tst) were used to determi...

Every type of neural rhythm has its own operational range of frequency. Neuronal mechanisms underlying rhythms at different frequencies, however, are poorly understood. We use a simple aquatic vertebrate, the two-day-old Xenopus tadpole, to investigate how the brainstem and spinal circuits generate swimming rhythms of different speeds. We first determined that the basic motor output pattern was...

background: physical exercise is known to be a stressor stimulus that leads to reproductive disruption.objective: the aim of this study was to evaluate the effect of forced swimming on the uterus and ovaries in mice.materials and methods: adult mice (n=24) were divided into the following threegroups: a, control; b, swimming in water (10popc); and c, swimming in water (23popc).swimmers swam for ...

Anguilliform or eel-like fishes are typically bottom dwellers, some of which are specialized burrowers. Although specializations for burrowing are predicted to affect the kinematics of swimming, it remains unknown to what extent this is actually the case. Here we examine swimming kinematics and efficiency of two burrowing anguilliform species, Pisodonophis boro and Heteroconger hassi, with diff...
