Aerobic power and muscle strength of individuals living with HIV/AIDS.
JOURNAL OF SPORTS MEDICINE AND PHYSICAL FITNESS(2014)
摘要
Aim. We wished to evaluate any continuing adverse effects upon peak aerobic power and muscle strength associated with either HAART therapy or persistently low CD4+ counts in men living with HIV/AIDS. Methods. We studied 39 HIV/AIDS patients with an average disease history of 6.1 years, and 28 normal sedentary volunteers. All subjects performed tests of peak aerobic power and isokinetic muscle force, and the HIV/AIDS group also completed the Profile of Mood States (POMS) and WHO Quality of Life questionnaires. Blood was sampled for standard measures of immune function (CD4+ and CD8+ counts) and viral load. Results. Patient values were generally as in the normal subjects and appeared to be uninfluenced by the CD4+ nadir or the use of HAART therapy. However, the isokinetic muscle strength was lower in individuals with a low current CD4+ count. Isokinetic strength was also negatively correlated with current CD4+ and CD8+ counts. Conclusion. HAART therapy does not appear to have an adverse long-term effect on either aerobic power or muscle strength. Many ambulatory volunteers living with HIV/AIDS have a normal peak aerobic power. However, isokinetic strength can remain low, particularly in those with low current T-cell counts.
