2017
The effect of short-term resistance training on elderly people was investigated through the simultaneous use of several methods. Compared to a control group, many improvements were seen, including on muscle aerobic capacity, glucose tolerance, strength, power, and muscle quality (i.e., protein involved in cell signaling and muscle fiber type composition).

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures. There are four defined lung volume measures: tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. Tidal volume is the amount of air inhaled and exhaled in a normal breath. Inspiratory...

Agar-Block Microcosms for Controlled Plant Tissue Decomposition by Aerobic Fungi

This video demonstrates a controlled environment approach to study degradation of lignocellulosic plant tissues by aerobic fungi. The ability to control nutrient sources and moisture is a key advantage of agar-block microcosms, but the approach often yields mixed success. We address critical pitfalls to yield reproducible, low-variability results.
FAQs
Performance depends on coordination among pulmonary, cardiovascular, vascular, and muscular processes. The lungs add oxygen to blood, the heart and blood vessels move it toward active tissue, and muscle mitochondria use it to generate energy through aerobic metabolism. A limitation in any part of this chain can influence the overall capacity measured during exercise.
Raising workload provides a changing demand against which oxygen use can be observed. Exercise testing therefore links the body's oxygen consumption with progressively greater physical effort, rather than treating performance as a resting characteristic. This relationship helps clinicians examine cardiorespiratory function and physical performance under sustained activity.
Changes in aerobic capacity can reflect how illness, aging, or medical treatment affects physical performance. Because the measure draws on lung oxygenation, cardiovascular delivery, and muscular oxygen use, shifts can provide context for evaluating cardiorespiratory function and exercise tolerance. It can also help track change over time.
During testing, a person performs sustained physical activity while workload increases. Clinicians measure oxygen consumption as the effort rises, using the response to evaluate cardiovascular and pulmonary function. The resulting information describes physical performance under exercise conditions and can support decisions about risk assessment, rehabilitation planning, or fitness monitoring.
In rehabilitation, aerobic capacity can help clinicians plan and monitor a person's return to physical activity. Its value comes from connecting measured oxygen use during exercise with functional performance, allowing changes to be followed as care proceeds. The measure may also contribute to evaluating how disease or treatment influences progress.
Monitoring is relevant when the goal is to assess cardiorespiratory fitness, physical performance, or functional health over time. Clinicians may use it for risk assessment and rehabilitation planning, while researchers can examine effects of disease, aging, and treatment. Repeated assessment can show whether performance changes in relation to those medical or biological influences.
