One measrue of physical fitness is a &quot;step test,&quot; in which a subject steps us on a low platform and then back down (one second for each), and continues this process for 3 minutes.aybe because your muscles are still requiring oxygen since they are still swollen from being used. Oxygen is transported to your muscles via your blood from your lungs and that could be the reason why your heart rate stays elevated.
Old headlights gave off 700 lumens of light; new headlights give off 1,000 to 1,200 lumens; high-intensity discharge lights (the term Xenon is really a misnomer, Bibbo said) give off 3,000 lumens.ld headlights gave off 700 lumens of light; new headlights give off 1,000 to 1,200 lumens; high-intensity discharge lights (the term Xenon is really a misnomer, Bibbo said) give off 3,000 lumens.
With newer light bulbs designed to use less energy, wattage is no longer a reliable way to gauge a light bulb's brightness. That takes lumens. Lumens measure brightness. A standard 60-watt incandescent bulb, for example, produces about 800 lumens of light.By comparison, a CFL bulb produces that same 800 lumens using less than 15 watts.umens = brightnesswatts = energy. Light bulbs are getting better. Newer bulbs â like halogen incandescents, CFLs and LEDs â last longer and use less energy than traditional incandescent bulbs, saving you money on your energy bills.
