Muscle Strength Genotype Predicts Functional Capacity at Older Age
Throughout the lifespan, maximum hand grip strength reflects general health and vigor and is therefore commonly suggested to be a biomarker of aging. Although aging results in declines in muscle strength, individual strength changes follow a predictable pattern, as shown by strong correlations between measurements carried out decades apart. Family and twin studies have also […]
A Sedentary Lifestyle Is Linked to Functional Decline, But Any Movement Can Help
Technological advancements in the past 60 years have led to an increasingly sedentary lifestyle. Changes in transportation, communication, the workplace and domestic entertainment have fostered environments in occupational, home and social settings that now demand or encourage sedentary behavior throughout most of the day. In recent years, we have become more aware of the negative […]
Capitalizing on Accelerometry to Measure Performance Fatigability in Older Adults
Fatigability is not a new concept in the exercise physiology realm. Researchers have long paired physical activity measures with ratings of perceived exertion or contractions of isolated muscle groups during tasks to quantify self-reported or muscle fatigability. Of late, the term “fatigability” has evolved and is widely used in aging research to represent a whole-body trait of […]
Computational Neuroscience Approaches to Exercise Behaviors in Older Adults
Engagement in physical exercise has shown widespread benefits on cardiovascular, physical, emotional and cognitive health in older adults. However, initiating and sustaining an exercise routine over the long term (e.g., six months or more) is incredibly challenging. Our historical understanding of the factors that determine engagement in physical exercise comes from psychological and psychosocial theories, […]
Cognitive Benefits of Physical Activity for Older Adults
Physical activity improves both physical and cognitive health, especially among older adults. Cognitive health encompasses many aspects of our daily functioning: memory, maintaining attention and concentration, dealing with distractions, solving problem and making decisions. Those cognitive functions tend to decline as we age, and physical activity can greatly prevent cognitive decline. For example, a meta-analysis has shown […]
High-Intensity Interval Training (HIIT) Enhances Neuroplasticity in Healthy Older Adults
Neuroplasticity is the ability of the brain to physiologically change due to our experiences. There is accumulating evidence for the benefits of a single session of aerobic exercise to enhance motor learning and neuroplasticity in young adults. Stationary cycling exercise performed immediately before or after skilled motor practice enhances motor learning that involves movements of […]
“Mind the Drift” of HR for Accurate Exercise Intensity Implementation in Prolonged Aerobic Exercise
An appropriate and individualized dose of regular aerobic exercise is recommended to promote and preserve cardiorespiratory health throughout life. The exercise dose is defined by four ingredients: frequency, intensity, time and type of exercise. Among these, intensity is the most elusive term of the exercise “prescription.” It is typically determined from an external load (such […]
Does Menopause Make Women More Sympathetic to Exercise?
Cardiovascular disease remains the leading cause of death in women, and hypertension is a major contributing factor, particularly after menopause. The sympathetic nervous system — historically viewed as the “fight or flight” part of our autonomic nervous system — is involved in regulating blood pressure (BP) and can contribute to the development of hypertension. Previous […]
More Than Head Trauma: Understanding Factors Related to Negative Health Outcomes in Former Football Players
The long-term effects of sport-related head trauma have gained notable attention from the scientific community, sport governing bodies, and the mainstream media in the past two decades. Concussions and repetitive head impacts that do not result in clear clinical signs and symptoms have been investigated as risk factors for worse health-related outcomes in later life. […]
Moving with Arthritis
The key to dealing with arthritis is to KEEP MOVING! Exercise is an essential part of a treatment plan for individuals with any type of arthritis. Arthritis expert A. Lynn Millar, PT, PhD, FACSM, shares important tips in this infographic.
