Cognitive Impairment, Healthy Participants

Keywords

Brief summary

Investigating the influence of a 12-week exercise regimen structured thrice weekly on cognitive capacity, and related hormones like Leptin, Irisin, BDNF hormones, antioxidant status, and inflammatory cytokines, whether these modulations potentially enhance neuroprotection and mitigate age-related cognitive impairment among healthy adults.

Detailed description

To elucidate the potential role of exercise as a buffer of cognitive impairment among healthy adults. We thought to investigate the effect of supervised aerobic training of moderate intensity on related hormones like Leptin, Irisin, BDNF hormones, antioxidant status, and inflammatory cytokines, whether these modulations potentially enhance neuroprotection and mitigate age-related cognitive impairment among healthy adults.

Inclusion criteria

* Sixty healthy individuals, aged 50 to 80 years (30 men/30 women), were invited to participate in this study after provided with informed consent and were included in this study. Also, all participants were of a sedentary lifestyle, with little or no physical activity during daily routine activities like work and transportation

Exclusion criteria

* To ensure accurate results, participants with obesity (BMI) ≥35 kg/m2.), physical impairments, movement limitations, chronic illnesses, such as kidney or liver diseases, or severe diabetes-related complications such as neuropathy, retinopathy, neuromuscular issues, cardiopulmonary conditions, or disorders affecting eating, the endocrine system, immune system, or mental health or those who undergoing glucocorticoid medication were excluded from this study

Design outcomes

Primary

MeasureTime frameDescription
Assessment of cognitive abilities6 monthsTrained research assistants assessed the cognitive abilities of older adult's pre and post supervised aerobic exercise using the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) battery. Assessments required between 45 and 90 minutes.
2- Leisure-time physical activity (LTPA)6 monthsA verified questionnaire was utilized to assess physical activity, specifically focusing on leisure-time physical activity (LTPA). In alignment with previous findings, we measured the weekly energy expenditure in terms of metabolic equivalents per hour per week (T-LPTA-MET/H/W
3-Assessment of apoptotic-related proteins6 monthBlood serum samples were collected from all participants in the early hours after a night of fasting, both before and after the exercise training regimen, to analyze apoptosis-related proteins. Immunoassay methods were used to measure serum Bcl-2 and cytochrome c levels. This involved using ELISA kits specifically designed for Bcl-2 (Cat# QIA23, Oncogene Research Products, Germany) and cytochrome c (Zymed ELISA Kit, Cat. No. 99-0040). Furthermore, the quantification of p53 concentration in the serum was determined utilizing a single-step enzyme-immunoassay ELISA kit (Catalog Number 11 828 789 001; Roche Diagnostics GmbH, Roche Applied Science, Germany) based on photometric methods.

Secondary

MeasureTime frameDescription
biochemical analysis of hormones, antioxidant enzymes, before and after exercise training6 monthThe levels of Leptin, Irisin, BDNF hormones, antioxidant status, and inflammatory cytokines were identified from the serum of all subjects, healthy and cognitively impaired subjects, before and after exercise sessions
