Individuals in the aerobic group exercised for about 45 minutes three times a week vigorously, raising their heart rates to between 70 and 85 % of optimum. Participants in the level of resistance group performed three sets of eight to 12 repetitions on eight split resistance machines 3 x weekly, exercising all major muscles. The amount of resistance experienced increased over the course of the scholarly study, to pay for the participants’ increasing strength. Participants in the combination group performed all the same exercises as participants in both the aerobic and resistance groups. At both the beginning and end of the study, researchers measured each participant’s fat, waistline circumference, body composition, and cardiopulmonary strength and fitness.The query of when to commence therapy remains In another new study it was discovered that HIV-infected patients are most likely to stay free from AIDS longer if they start medication therapy when their immune systems are still relatively strong.
