ESHE 392 Exercise Physiology Common measurements in Exercise Physiology Metric system used to express mass length and volume System International SI For standardizing units of measurements Remember to convert into metric system Dr Newsome will provide it in exams Work force x distance In SI units Work J force N x distance m Example Lifting a 10 kg weight up a distance of 2 m 1 kg 981 N so 10kg 981 N W F x d W 981N x 2m 1962 Nm 1962J 1Nm U so 1962 Nm 1962J Kilopond meter kpm l kpm 981 J Kilocalorie kcal lkcal 4186J or 4186 kJ lkcal 4268kpm Joule J l J l newtonmeter Nm l J 239 x10A4 kcal U 0102 kpm Power work time In SI units Power W work J time s Example Performing 20000J of work in 60s 1W 1 Js1so 3333 Js1 3333 W 20000 J 60 s 3333 Js1 3333 W Lots of power in a short time frame more POWERFUL J oulesSecond Al Watts Power F x d t Watt W l W 1 stAl lW 612 kpm x minAl Horsepower hp 7457 W Kilopond meter lkpm x minAl 0163 W Ergometry Measurement of work output Ergometer Device used to measure work Bench step ergometer cycle ergometer treadmill cycle ergometer Bench Step Subject steps up and down at speci ed rate Example 70kg subject 03 m step 30 stepss minAl for 10 min Total work force x distance Force 70kg x 981 kagAl 6867 N Work 03mstep x 30 stepmin x 10 min 90m 6867 N x 90m 61803 J 618kJ Power worktime 61803 600 s 103 JsA1103 W Cycle Ergometer Stationary cycle that allows accurate measurement of work performed Example 15 kg 147N resistance 6 mrevAl 60 revminAl for 10 min Total work 147 N x 6mrev x 60revmin x 10 min 52920 J 15kg X 6mrevA1 X 60 revminAl X 10 min 5400 kgm Power 52290 J 600 s 882 JsA1 882 W 5400 kgm 10 min 540 kgmmin Treadmill Calculation of work performed while a subject runs or walks on a treadmill is not generally possible when the treadmill is horizontal Even though running horizontal on a treadmill requires energy Quantifiable work is being performed when walking or running up a slope Incline of the treadmill is eXpressed in percent grade Amount of vertical rise per 100unit of belt travel 10 grade means 10 m vertical rise for 100 m of belt travel Determination of percent grade on treadmill Grade sin theta Rise Hypotenuse EXample 60 kg 5886 N subject speed 200 mminAl for 10 min Vertical displacement grade X distance 200 mmin x x 10 min 150 m Work body weight X total vertical distance 5886 N X 150 m 88290 J 883 kJ 60 kg X 0075 X 200 mmin X 10 min 9000 kgm Direct Calorimetry Measurement of heat production as an indication of metabolic rate Foodstuffs 02 9 ATP heat 9 heat Commonly measured in calories 1 kilocalorie kcal 1000 calories 1kcal 4186 J or 4186 kJ Indirect calorimetry Measurement of oXygen consumption as an eXtimate of resting metabolic rate Food stuffs 02 9 heat co2 h2O
