See the list below: 1  Alpha 1-antitrypsin: 20-50 Âµmol/L. 2  Angiotensin-converting enzyme: 23-57 U/L. 3  C-reactive protein: < 5 mg/L. 4  D-dimer: < 500 ng/mL. 5  Erythrocyte sedimentation rate (ESR): Less than age/2 mm/hour. 6  Lactate dehydrogenase (LDH): 50-150 U/L. 7  Lead: < 40 Âµg/dL. 8  Rheumatoid factor: < 25 IU/ml.
1 The average walking speed for older pedestrians was 4.11 feet per second, compared with 4.95 for younger pedestrians. 2  Older females had the slowest walking speed at 3.89 feet per second.
Record. While the average U.S. adult walks 2.5 to 3 miles per day, the maximum an adult can walk per day is much more than that. An average adult can walk 3 to 4 miles per hour at a comfortable pace or 96 miles in 24 hours.The world record for the most miles walked in 24 hours was set by Paul Forthomme in 1984.wo thousand steps equals roughly a mile of walking. So, the average American walks about 2.5 to 3 miles per day. Assessing the number of steps a person takes during a day is complicated by the inaccuracies of pedometers and accelerometers.
