Summary
Combined exercise and cognitive training (CT) improved cognition in older adults with mild cognitive impairment (MCI). Aquatic exercise combined with CT showed broader cognitive benefits than land-based exercise.
Area of Science:
- Gerontology
- Neuroscience
- Rehabilitation Science
Background:
- Mild cognitive impairment (MCI) is a critical stage for intervention.
- Exercise and cognitive training (CT) show independent benefits for cognition.
- Combined interventions may offer maximal cognitive benefits, with aquatic exercise being less studied.
Purpose of the Study:
- To investigate the impact of combined exercise (water- or land-based) and CT on cognitive function in older adults with MCI.
Main Methods:
- 67 adults (54-86 years) with MCI participated.
- Interventions included 6 months of land or aquatic exercise followed by 4 weeks of CT.
- Cognitive domains were assessed at baseline, post-exercise, and post-CT using linear mixed effects modeling.
Main Results:
- Both exercise types combined with CT significantly improved learning and memory.
- Executive functioning, processing speed, language, and visuospatial abilities improved only in the aquatic exercise and CT group.
- No significant differences in linear growth patterns were found between groups.
Conclusions:
- Combined aquatic exercise and CT interventions may yield broader cognitive benefits for individuals with MCI.
- Full engagement in exercise is crucial for global cognitive improvements.
- Aquatic-based activities warrant further consideration for MCI interventions.

01:30Cognitive Development During Adulthood

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
196
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

01:27Exercise and Muscle Performance
1.6K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
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...
