Effects of resistance training on muscle strength, body composition and immune-inflammatory markers in people living with HIV: a systematic review and Meta-analysis of randomized controlled trials.

The purpose of this review is to evaluate the effect of resistance training (RT) as a unique intervention on muscle strength, body composition, and immune-inflammatory markers in people living with HIV (PLHIV). The searches were conducted in seven databases and included published randomized clinical trials that assessed the effect of RT vs. no exercise on muscle strength, body composition, and immune-inflammatory markers in PLHIV until June 2021.

Isometric handgrip exercise training reduces resting systolic blood pressure but does not interfere with diastolic blood pressure and heart rate variability in hypertensive subjects: a systematic review and meta-analysis of randomized clinical trials.

To evaluate the effects of isometric handgrip exercise training (IHET) on blood pressure and heart rate variability in hypertensive subjects. Five databases were searched for randomized clinical trials in English, Spanish, or Portuguese evaluating the effect of IHET vs. no exercise on blood pressure (systolic and/or diastolic) and/or heart rate variability (low frequency [LF], high frequency [HF], and/or LF/HF ratio) through December 2020.

The thyroid hormone receptor β-selective agonist GC-1 does not affect tolerance to exercise in hypothyroid rats.

Objective: Investigate the effect of GC-1 on tolerance to exercise in rats with experimental hypothyroidism.

Materials And Methods: Hypothyroidism was induced with methimazole sodium and perchlorate treatment. Six groups with eight animals were studied: control group (C), hypothyroid group without treatment (HYPO); hypothyroidism treated with physiological doses of tetraiodothyronine (T4) or 10 times higher (10×T4); hypothyroidism treated with equal molar doses of GC-1 (GC-1) or 10 times higher (10×GC-1).
