The objective of a recent retrospective study was to examine the safety and effectiveness(Of a drug or treatment). The maximum ability of a drug or treatment to produce a result regardless of dosage. A drug passes efficacy trials if it is effective at the dose tested and against the illness for which it is prescribed. In the standard procedure, Phase II clinical trials gauge efficacy, and Phase III trials confirm it. of aerobic exercise interventions on immunologic and virologic, cardiopulmonary, psychological outcomes and strength, weight, and body composition in people with HIV.
The authors of the study searched databases between 1980 and June 2009, scanned abstracts and proceedings from major international and national HIV conferences and did a hand search of reference lists and tables of contents of relevant journals and books.
They included studies of randomisedA method based on chance by which study participants are assigned to a treatment group. Randomization minimizes the differences among groups by equally distributing people with particular characteristics among all the trial arms. The researchers do not know which treatment is better. From what is known at the time, any one of the treatments chosen could be of benefit to the participant controlled trials comparing aerobic exercise interventions with no aerobic exercise interventions or another exercise or treatment modality, performed at least three times a week for at least four weeks among people with HIV.
Their results show that performing constant or interval aerobic exercise, or a combination of constant aerobic exercise (e.g. walking) and progressive resistive exercise (e.g. weights) for at least 20 minutes at least three times a week for at least five weeks is both safe and leads to significant improvements in cardiopulmonary fitness (maximum oxygen consumption), body composition (leg muscle area, percent body fat), and psychological status (depression-dejection symptoms).
There is insufficient information about the effects on women and older people, but that’s no excuse for any of us to sit around waiting for more data.
