Fitness Terminology

 

AEROBIC FITNESS

Aerobic Fitness is endurance fitness, the ability to perform prolonged periods of aerobic work. In aerobic work, the oxygen obtained from the air is used for the combustion of fat and carbohydrates creating the energy necessary to perform the work.

 

MAXIMAL OXYGEN UPTAKE (Vo2 max)

Vo2 max is maximal oxygen uptake which indicates aerobic fitness - the ability to sustain work for prolonged periods. This is usually experienced in the abilities to walk, run, and climb uphill, swim, and other activities performed continuously for more than 15 minutes. Aerobic fitness is related to health. Fit people are usually healthier than unfit ones. Vo2 max is the best way to measure the aerobic fitness of an individual. The test consists of walking/running on a treadmill, or cycling on a bicycle ergometer at increased loads, for 12 to 15 minutes. The oxygen used during the maximal effort is the maximal oxygen uptake (Vo2 max). The higher the Vo2 max the fitter is the individual. The UFT predicts Vo2 max using a 30 seconds step test.

 

ABSOLUTE AND RELATIVE Vo2 max

Vo2 max is expressed as an absolute, or relative value. Absolute Vo2 max is simply the maximal oxygen uptake expressed in liters per minute. Absolute fitness is important in activities where body weight is not lifted such as in cycling, swimming and handling of objects and weights, other than body weight. Relative Vo2 max is absolute Vo2 max divided by body weight and it is expressed in milliliters of oxygen per body weight (kg) per minute (ml/kg/min). Relative Vo2 max is important in activities where body weight is lifted such as in walking, running and climbing uphill. In adults, relative Vo2 max is more important than absolute Vo2 max as a health indicator.

 

UFT

Universal Fitness Tester. Predicts aerobic fitness and related capabilities using a 30-second step test.

 

AEROBIC FITNESS SCORES AND CATEGORIES

The UFT system rates each absolute and relative Vo2 max value by the assignment of fitness scores and categories. The scores are age-sex adjusted, i.e., they rate an individual in relation to his/her age-sex group, according to aerobic fitness norms in the general population*. The scores range from below 48 indicating very poor fitness, to 70 indicating average fitness, to 100 indicating excellent fitness. The fitness categories are related to the fitness scores . Seven fitness categories are included: Excellent, Very Good, Good, Average, Fair, Poor and Very poor.

MATHR

Maximal Allowable Training Heart Rate. The UFT system calculates the recommended exercise heart rate for each individual based on age,gender, weight, and fitness level. MATHR is the maximum heart rate that should not be exceeded during an exercise session.
