To determine if users of indoor firing ranges may be at risk from lead exposure, we studied a law enforcement trainee class during three months of firearms instruction. Blood lead levels were obtained before training and at four-week intervals during training. Air lead levels were measured three times during instruction. Blood lead levels rose from a pre-training mean of 0.31 mumol/L to 2.47 mu...

Lead is a highly neurotoxic agent that particularly affects the developing central nervous system. In the current study we investigated the neuroprotective effects of exercise training and/or diferuloyl methane (DM) supplement, which is known as curcumin, on lead acetate-induced neurotoxicity in the rat hippocampus. Sixty rats were randomly divided into six groups: 1) lead acetate, 2) DM supple...

In this study, we investigated whether mixing easy and difficult trials can lead to learning in the difficult conditions. We hypothesized that while feedback is necessary for significant learning in training regimes consisting solely of low training accuracy trials, training mixtures with sufficient proportions of high accuracy training trials would lead to significant learning without feedback...

The ability to attend and to exercise cognitive control are vital aspects of human adaptability. Several studies indicate that attention training using computer based exercises can lead to improved attention in children and adults. Randomized control studies of exposure to nature, mindfulness and integrative body-mind training (IBMT) yield improved attention and self-regulation. Here, we ask ho...

this study aimed to assess the effects of four weeks of detraining after eight weeks of intense sprint training on risk factors of atherogenic inflammatory damages. for this purpose, 42 male rats were divided randomly into two groups: sprint training group (experimental) (n=24 and weight 210±7) and control group (n=18 and weight 211±3). the training program was performed for 12 weeks, three ses...

background: exercise has positive and negative effects on immune system. herein, we would like to investigate the effects of incremental aerobic training and fish oil supplementation on the plasma levels of crp, cpk and il-17 in trained mice. one of the major roles of immune system is to produce soluble or cellular components that provide the immunity against inflammatory agent. the purpose of ...
