Our findings, though mediated by different mechanisms, are synchronous with a previous report [17] that caloric restriction reduces reflex control of the circulation during orthostatic stress. Overall, the reduced HR and BP responses are consistent with physiological adaptation to reduced caloric intake. For example, reduced caloric or fat intake lowered HR and BP in rats [15, 16, 26] and humans [24, 27]. From this investigation, it is not apparently clear why the response is drastically reduced following caloric restriction. During static exercise, activation of central command and the mechanoreflex predominantly control the increase in HR, whereas BP is regulated by mechano- and metaboreflexes together with central command, and MSNA is mainly regulated by the metaboreflex [11]. Alterations can occur at a number of points along the muscle mechano- and metaboreflex arcs (e.g., afferent response, central integration, efferent signal) and central command in addition to changes in stimuli and end-organ responses. From our results, it seems most likely that central command and/or the mechanoreflex are attenuated.","tracks":[{"project":"TEST0","denotations":[{"id":"26793301-70-76-73104","span":{"begin":567,"end":569},"obj":"[\"11959690\"]"},{"id":"26793301-74-80-73105","span":{"begin":571,"end":573},"obj":"[\"867049\"]"},{"id":"26793301-78-84-73106","span":{"begin":575,"end":577},"obj":"[\"16581971\"]"},{"id":"26793301-94-100-73107","span":{"begin":591,"end":593},"obj":"[\"8390511\"]"},{"id":"26793301-98-104-73108","span":{"begin":595,"end":597},"obj":"[\"9561280\"]"},{"id":"26793301-230-236-73109","span":{"begin":977,"end":979},"obj":"[\"2228848\"]"}],"attributes":[{"subj":"26793301-70-76-73104","pred":"source","obj":"TEST0"},{"subj":"26793301-74-80-73105","pred":"source","obj":"TEST0"},{"subj":"26793301-78-84-73106","pred":"source","obj":"TEST0"},{"subj":"26793301-94-100-73107","pred":"source","obj":"TEST0"},{"subj":"26793301-98-104-73108","pred":"source","obj":"TEST0"},{"subj":"26793301-230-236-73109","pred":"source","obj":"TEST0"}]},{"project":"MyTest","denotations":[{"id":"26793301-11959690-30256723","span":{"begin":567,"end":569},"obj":"11959690"},{"id":"26793301-867049-30256724","span":{"begin":571,"end":573},"obj":"867049"},{"id":"26793301-16581971-30256725","span":{"begin":575,"end":577},"obj":"16581971"},{"id":"26793301-8390511-30256726","span":{"begin":591,"end":593},"obj":"8390511"},{"id":"26793301-9561280-30256727","span":{"begin":595,"end":597},"obj":"9561280"},{"id":"26793301-2228848-30256728","span":{"begin":977,"end":979},"obj":"2228848"}],"namespaces":[{"prefix":"_base","uri":"https://www.uniprot.org/uniprot/testbase"},{"prefix":"UniProtKB","uri":"https://www.uniprot.org/uniprot/"},{"prefix":"uniprot","uri":"https://www.uniprot.org/uniprotkb/"}],"attributes":[{"subj":"26793301-11959690-30256723","pred":"source","obj":"MyTest"},{"subj":"26793301-867049-30256724","pred":"source","obj":"MyTest"},{"subj":"26793301-16581971-30256725","pred":"source","obj":"MyTest"},{"subj":"26793301-8390511-30256726","pred":"source","obj":"MyTest"},{"subj":"26793301-9561280-30256727","pred":"source","obj":"MyTest"},{"subj":"26793301-2228848-30256728","pred":"source","obj":"MyTest"}]},{"project":"0_colil","denotations":[{"id":"26793301-11959690-73104","span":{"begin":567,"end":569},"obj":"11959690"},{"id":"26793301-867049-73105","span":{"begin":571,"end":573},"obj":"867049"},{"id":"26793301-16581971-73106","span":{"begin":575,"end":577},"obj":"16581971"},{"id":"26793301-8390511-73107","span":{"begin":591,"end":593},"obj":"8390511"},{"id":"26793301-9561280-73108","span":{"begin":595,"end":597},"obj":"9561280"},{"id":"26793301-2228848-73109","span":{"begin":977,"end":979},"obj":"2228848"}],"attributes":[{"subj":"26793301-11959690-73104","pred":"source","obj":"0_colil"},{"subj":"26793301-867049-73105","pred":"source","obj":"0_colil"},{"subj":"26793301-16581971-73106","pred":"source","obj":"0_colil"},{"subj":"26793301-8390511-73107","pred":"source","obj":"0_colil"},{"subj":"26793301-9561280-73108","pred":"source","obj":"0_colil"},{"subj":"26793301-2228848-73109","pred":"source","obj":"0_colil"}]},{"project":"2_test","denotations":[{"id":"26793301-11959690-30256723","span":{"begin":567,"end":569},"obj":"11959690"},{"id":"26793301-867049-30256724","span":{"begin":571,"end":573},"obj":"867049"},{"id":"26793301-16581971-30256725","span":{"begin":575,"end":577},"obj":"16581971"},{"id":"26793301-8390511-30256726","span":{"begin":591,"end":593},"obj":"8390511"},{"id":"26793301-9561280-30256727","span":{"begin":595,"end":597},"obj":"9561280"},{"id":"26793301-2228848-30256728","span":{"begin":977,"end":979},"obj":"2228848"}],"attributes":[{"subj":"26793301-11959690-30256723","pred":"source","obj":"2_test"},{"subj":"26793301-867049-30256724","pred":"source","obj":"2_test"},{"subj":"26793301-16581971-30256725","pred":"source","obj":"2_test"},{"subj":"26793301-8390511-30256726","pred":"source","obj":"2_test"},{"subj":"26793301-9561280-30256727","pred":"source","obj":"2_test"},{"subj":"26793301-2228848-30256728","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"TEST0","color":"#ec93b3","default":true},{"id":"MyTest","color":"#93cdec"},{"id":"0_colil","color":"#e8ec93"},{"id":"2_test","color":"#d693ec"}]}]}}
