Meeting the 50th Percentile for 24-hour Movement Helps Cognitive Function
Alzheimer’s disease and related dementias are debilitating conditions leading to impaired cognitive processes and worsening physical functioning. They place significant burden on caregivers and health care systems. Roughly 15 million cases of cognitive impairment and Alzheimer’s disease in the U.S. are projected by 2060. While there are no medical treatments to delay Alzheimer’s disease progression, […]
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, […]
Cancer Survivors with Chronic Fatigue Display Rapid Impairments in Muscle Function During Exercise
Cancer-related fatigue (C-rF) is a debilitating symptom that affects around one-third of people for months or years after cancer treatment. While the etiology of C-rF remains uncertain, it has been demonstrated that cancer survivors with C-rF display impaired exercise tolerance compared with those without C-rF, with the degree of exercise intolerance associated with chronic fatigue […]
Cardiac Adaptation to Endurance and Resistance Training
In our Studies of Twin Responses to Understand Exercise THerapy (STRUETH) trial, we recruited monozygotic and dizygotic twin pairs and supervised them through three months of endurance training and three months of resistance exercise training. Each twin pair exercised together, at matched exercise prescriptions, and all subjects undertook both forms of exercise. We measured many […]
Racial, Ethnic, and Nativity-Based Differences in Physical Activity Behaviors
As exercise professionals ranging from clinicians to personal trainers to researchers, we know that most adults in the United States are not getting enough moderate-to-vigorous intensity aerobic physical activity (MVPA). It is important for us to understand who may be at especially high risk of physical inactivity. Prior studies have shown that there may be […]
Q&A with New ACSM President Stacy Fischer
Anastasia “Stacy” Fischer, M.D., FACSM, was installed as president of ACSM during last month’s annual meeting in San Diego. SMB editor Lenny Kaminsky, Ph.D., FACSM, asked Dr. Fischer several questions that may be of interest to ACSM members. We appreciate Dr. Fischer taking the time to provide the following answers. Q: What can you say about ACSM’s annual meeting, the […]
Reconsidering the Importance of Cardiorespiratory Fitness in Early Adulthood
Cardiorespiratory fitness reflects integration of several body systems, including the cardiovascular, respiratory and musculoskeletal systems. It helps optimize heart health and is an important predictor of adverse health outcomes, including premature death, heart attack and heart disease. Indeed, the American Heart Association suggests that cardiorespiratory fitness should be measured as a vital sign during a doctor’s visit. […]
Air Pollution Diminishes the Benefits of Physical Activity for Brain Health
Physical activity is recognized as one of the key healthy lifestyle behaviors that reduces the risk of developing dementia late in life. Physical activity requires increased rates of respiration. Thus, in areas with high levels of air pollution, physical activity may increase exposure to particulate matter and gases that are linked with higher risk of […]
Sedentary Behavior and Physical Activity Are Associated with Cardiac Fat
Obesity is a primary etiology of many adverse health outcomes. The body has two primary types of fat tissue: subcutaneous fat and visceral fat. Subcutaneous fat is the adipose tissue that lies below the surface of the skin, whereas visceral fat is the adipose tissue that lines the internal organs. Visceral fat, compared to subcutaneous […]
Learning from Experience: Growth Potential of Exercise from Free-Living Protein Synthesis in Men and Women
Skeletal muscle is the engine that drives human health and performance and is influenced by modifiable healthy lifestyle behaviors (i.e., nutrition and exercise) and non-modifiable factors (i.e., sex and age). It is well-established that resistance exercise stimulates the synthesis of skeletal muscle protein (especially the force-generating myofibrillar fraction) for up to 48 hours. This ultimately […]
