Background:
This systematic review with meta-analysis aimed to compare the changes caused by exercise intervention with those provoked by usual care on physical function biomarkers in older adults immediately after hospital discharge.
Methods:
Two independent authors performed a systematic search (PubMed, Scopus, Web of Science, and SciELO) of studies published from database inception until August 2021. Randomized clinical trials investigating the effects of an exercise intervention compared to usual care were included. The Cochrane Collaboration assessment tool was used to analyze the risk of bias. The comparisons included handgrip strength, the short physical performance battery scale, six-minute walking test, and 10-m gait speed.
Results:
Overall, the exercise intervention led to significantly greater changes compared to usual care in physical function biomarkers [standard mean difference = 0.89, 95% CI = 0.39, 1.42; P = 0.001]. However, considering the very few studies investigating each variable separately, our sub-analysis did not reveal a significant effect of the exercise intervention on handgrip strength, the short physical performance battery, six minutes walking test, and 10-m gait speed.
Conclusions:
This systematic review with meta-analysis of randomized clinical trials suggests that exercise intervention induce greater physical function biomarker alterations in older adults after hospitalization than usual care including physical activity guidance. Future trials comparing the effects of these intervention groups on physical function biomarkers in this population are needed to confirm our results.

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
