{ "item_title" : "The Science of Track & Field", "item_author" : [" M. Schottenbauer "], "item_description" : "This book contains graphs showing data on the biophysics of track and field activities, including joint angles/positions, electrical activity of the heart (EKG) and muscles (EMG), breathing rate, lung volume, blood pressure, and pulse. Track and field activities examined include running, jumping, and throwing. Analyses include hurdles, discus, hammer, javelin, and shot put. These data can be used for lesson plans by teachers and parents. Note: These data were collected using lightweight track and field equipment, and with constrained physical exertion, due to limitations of lab space, equipment, and safety considerations. Most throws were limited to 14 feet. Actual forces generated in competitive track and field events are larger. These biophysics data are samples from one individual and are not representative of the population.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/1/49/740/513/1497405130_b.jpg", "price_data" : { "retail_price" : "17.00", "online_price" : "17.00", "our_price" : "17.00", "club_price" : "17.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
