to find out, Kid Miikka Kiprusoff Jersey Dan decided to make this question the focus of his seventh grade science fair project. GAME PLAN To kick off his project, Dan performed research to find Elite Red TJ Brodie Youth Mason Raymond Jersey Jersey out what forces act Elite Kris Russell Jersey on a Authenitc White Jarome Iginla Jersey football during play. Based on the information that he gathered, he developed a hypothesis, or Elite White Jarome Iginla Jersey a possible answer to a scientific question. Women Rasmus Andersson Jersey Like any good hypothesis, Dan’s was testable:There is an ideal air pressure for footballs. When a football is inflated or deflated beyond that Authenitc Jarome Iginla Jersey Elite White Women Brandon Bollig Jersey Jarome Iginla Jersey ideal amount, it will not travel Youth Dennis Wideman Jersey as far when it is kicked. Before Dan Men Kris Russell Jersey could design an experiment to test his hypothesis, he Authenitc Red Devin Setoguchi Jersey Men Dennis Wideman Jersey had to Kid Jarome Iginla Jersey tackle a construction project. The Men Jarome Iginla Jersey teen knew he couldn’t kick a football with the same amount of force every time. That would be a problem for a science experiment: "With an inconsistent kick, your data wouldn’t be correct, and you wouldn’t prove anything," Dan explains. So with help from his dad, Dan built a kicking machine. By winding the Women Jarome Iginla Jersey machine’s "leg" and then releasing
Elevated Youth Rasmus Andersson Jersey body mass in National Football League players linked to cognitive impairment and decreased prefrontal cortex and temporal pole activityTop of pageAbstractObesity is a risk factor Youth Brandon Bollig Jersey Elite Red Johnny Gaudreau Jersey for neurodegenerative disease and has been shown to adversely affect cognitive function. Professional athletes who participate in sports, which expose them to repetitive concussions, may be at heightened risk for cognitive impairment. Here, we investigated the effects of body mass as measured by waist to height ratio (WHtR) on regional cerebral blood flow using single photon emission computed tomography imaging in 38 healthy weight (WHtR mean 49.34 age 58 and 38 overweight (WHtR mean 58.7 age 58 retired National Football League football players. After matching for age and position, we used a two sample t test to determine the differences in blood flow in healthy versus overweight subjects. Statistical parametric mapping revealed a higher WHtR ratio is associated with decreased blood flow in Brodmann areas
