Procedure \ ind device for support and, if necessary, Monitoring aerobic fitness training exercises

The invention relates to a method and a device to support and monitor aerobic fitness training exercises.

It has been found that only aerobic training exercises d < Increase cardiovascular fitness because of such Exercises significantly increase the continuous flow of blood through the heart and the large skeletal muscles cause. The best aerobic exercise exercises are fast walking, jogging, fast cycling, running, swimming, ice and roller skating, and style jump.

The problems associated with fitness training exercises are twofold: On the one hand, the exercises, which generally require vigorous movement of both arms and legs, are to be held for 20 minutes or longer at the so-called training target level. This training target zone is between 70 and 85 % of the maximum achievable heartbeat frequency, roughly 220 heartbeats per minute minus the respective age in years. Women achieve the same maximum heart rate as men of comparable age. Below 70 % of the target zone capacity, the exercises only produce a slight fitness effect. Above 85 %, increased exercise efforts produce only a slight additional fitness effect.

On the other hand, the user of pit training equipment must currently a pulse measurement every 5 minutes to determine the force required to reach the target zone area.

Such a fitness program should essentially comprise three main stages or phases, namely a "warm-up" or start-up phase, the aforementioned training target zone and a "cool-down" or run-out phase. The warm-up or start-up phase should take 5 to 10 minutes the heartbeat rate at the end of this start-up period should be less than 50 % of the maximum achievable heartbeat rate of the user

immediately after the warm-up or start-up period, the Training exercises are intensified until the mentioned training target zone is reached. This section should 20 up to 30 minutes. The pulse count is repeated at 5 minute intervals.

The Ahkiihl- or run-out phase takes place by reducing of exercise effort for a period of 5 to 10 minutes before the end of exercise. At the end of this AV cooling or start-up phase, the pulse should open again a value of less than 50% of the maximum achievable Heart rate decreased.

The program should be at least three times a week be performed. Of course, there is a problem with the user having to persist in this program encourage and motivate su. The object of the invention is to create a method and a device

909812/0608

for the support and, if necessary, monitoring of such? itnesetraining exercises, such that the User is encouraged and motivated to stick to the program.

Subject the basic idea of the invention is provided for this purpose that the user an exercise device, such as a treadmill, a bicycle or rowing simulator or the like is used, with the respective speed and the distance traveled are displayed on a monitor; in addition, the pulse or heartbeat frequency of the user is measured and displayed and, in addition, an exterior shot of a corresponding training scene (such as a rower in a boat) at variable speed shown to the user if the Monitor is a television set.

According to preferred embodiments of the invention it is provided that the speed signal of the user Playback speed of a video tape cassette player controls so that the playback speed of the outdoor exercise scene recorded accordingly is changed. The speed signal is converted into the reciprocal of the speed, i.e. H. in minutes per Heal, transformed and the distance shown to within hundredths of a heal. These two last-mentioned signals

ν Deileal signals are converted into binary coded (BCD) / digits and superimposed on the video signal for playback on the scene display on the monitor via a circuit for generating and positioning television fade-ins. The heartbeat is recorded electrically or by means of an infrared Heßwandler and converted into a three-digit display size
