Improvement in Muscular Strength in HIV-Infected Individuals Receiving Antiretroviral Therapy.

Purpose: This study investigated (1) the effect of a progressive resistance training (PRT) program and whey protein intake on maximal muscle strength in human immunodeficiency virus (HIV)-infected individuals receiving antiretroviral therapy (ART) and (2) alterations in maximal strength 12 wks after the cessation of PRT with continued supplementation.

Methods: Sixty HIV-infected individuals were recruited. Whole body PRT was performed twice weekly for 12 wks.

Heart rate variability in physically active individuals: reliability and gender characteristics.

Purpose: To evaluate the reliability of short-term recordings (five minutes) of heart rate variability (HRV) and the association between HRV and gender.

Methods: HRV time- and frequency-domain parameters were calculated in 44 physically active students (21 males and 23 females) over four consecutive days. A Suunto t6 heart rate monitor was used to obtain inter-beat intervals (IBIs) that were then transferred to Kubios HRV analysis software.
