Growing evidence suggests that exercise can provide neuroprotection by improving mitochondrial quality control (MQC) on the aged brain. Adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) signaling responsiveness declines with aging. However， whether AMPK plays a role in the exercise-mediated improvement of memory and MQC in the aged hippocampus remains to be established. AICAR (5-Aminoimidazole 4-carboxamide ribonucleoside)， a pharmacological agonist of AMPK， has been proposed to be an exercise mimetic recently. However， it has not been clarified whether AICAR could mimic the effects of exercise on the aged hippocampus through improvement of MQC. In this study， AICAR (AMPK agonist) and Compound C (AMPK inhibitor) were used to investigate if AMPK plays a key role in exercise-induced improvement of MQC and if AICAR could act as an exercise mimetic through improvement of MQC in aged hippocampus. Both exercise and AICAR improved the memory of aged mice and increased AMPK phosphorylation in the aged hippocampus. exercise， but not AICAR， improved mitochondrial respiratory function in the aged hippocampus and increased the Microtubule associated protein 1 light chain 3 (LC3) II/LC3 I ratio and the protein expression of LC3 II and Autophagy Related Protein 7 (ATG7) in the lysate of whole hippocampal tissue. Both exercise and AICAR increased the ratio of LC3 II/LC3 I and the protein expression of LC3 II in the mitochondrial fractions of the hippocampus. Regarding mitochondrial dynamics， neither exercise training nor AICAR changed the protein level of Mitofusin2 (Mfn2). exercise， but not AICAR， increased the protein level of Dynamin-related protein 1 (Drp1). Furthermore， both exercise training and AICAR increased the protein level of peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α)， a modulator of mitochondrial biogenesis. Compound C abolished the exercise-induced effects on memory in aged mice (Fig. 1)， AMPK phosphorylation， autophagy， mitop

A short tablet-based cognitive task was completed prior to and during（50 and 55 min into exercise） each ***: The exercise conditions facilitated response time（p = 0.009）, although the extent of this effect was not as strong in the variable exercise conditions（p = 0.011–0.089）. High intensity exercise periods resulted in some cognitive regression back towards control trial *** in cardiorespiratory measures and periods of hypocapnia could not explain changes in cognitive ***: Changes in cognitive performance with variations in exercise intensity are likely to have implications for sport and occupational settings.

Background: Physical activity(PA) has been shown to benefit cognitive function in older adults. However, the cognitive benefits of exercising for older Chinese adults have not been systematically documented. This study was to conduct a systematic review on evidence that PA is beneficial for cognitive functioning in older Chinese ***: Major databases, including Pub Med, EMBASE, Cochrane Library, Wan Fang, CNKI, and VIP, were searched for studies published in English or Chinese between January 2000 and December 2015. Randomized and non-randomized controlled trials(RCTs and non-RCTs), cohort,case-control and cross-sectional studies that evaluated PA and cognitive function among older Chinese adults were included in this ***: Of 53 studies included and reviewed, 33 were observational(22 cross-sectional, 7 case-control, and 4 cohort) and 20 were experimental(15 RCTs, 5 non-RCTs). Observational studies showed an association of reduced risk of cognitive-related diseases(i.e., mild cognitive impairment, Alzheimer's disease, and dementia) through PA, whereas experimental studies reported exercise-induced improvement in multiple domains of cognitive function(i.e., global cognitive function, memory, executive function, attention, language, and processing recourse).Conclusion: This systematic review provides initial evidence that PA may benefit cognition in older Chinese adults. Further studies of individuals with cognitive impairments and prospective and RCT studies having high scientific rigor are needed to corroborate the findings reported in this review.
