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).

Here, we present protocols of high-intensity interval and moderate-intensity continuous exercise to observe the response of circulating cardiac troponin T (cTnT) concentration to acute exercise over 10 days. The information may assist with clinical interpretations of post-exercise cTnT elevation and guide the prescription of exercise.

Short session (≤10 min) high intensity interval training (HIIT) is emerging as an alternative to longer exercise modalities, yet the shorter variants are rarely modeled in animal studies. Here, we describe a 10 min, 3 day a week, uphill treadmill HIIT protocol that enhances physical performance in male and female aged mice.
FAQs
As effort rises during sustained exercise, the cardiovascular and respiratory systems must increase their contribution to meet greater energy demands. Oxygen uptake consequently increases, helping indicate how much aerobic work the body is performing. At higher levels, key physiological thresholds may be exceeded, and lactate accumulation becomes more prominent, signaling a meaningful shift in the exercise response.
These measures describe intensity from complementary perspectives. Heart rate reflects cardiovascular response, while oxygen consumption indicates the body’s demand for oxygen. Perceived exertion captures how difficult the effort feels, and the talk test provides a practical behavioral indicator. Using more than one measure can help relate physiological workload to the individual’s experience during exercise.
Thresholds help distinguish different physiological responses to increasing effort rather than treating all exercise as equivalent. Below important thresholds, oxygen uptake may rise without the same degree of lactate accumulation. Beyond them, lactate becomes more evident, identifying a higher-demand level that may be important when matching exercise intensity to fitness, health status, or rehabilitation goals.
Selection should reflect the person’s fitness, health status, and intended rehabilitation goal. Clinicians can use heart rate, oxygen consumption, perceived exertion, or the talk test to characterize the effort and adjust it appropriately. This individualized approach helps avoid prescribing an intensity that is excessive for the patient or too low to support meaningful improvements.
Assessment is particularly useful when exercise forms part of rehabilitation, disease management, or a program intended to improve functional capacity. Objective and subjective measures allow the exercise demand to be related to the person’s current condition rather than applied uniformly. This supports more appropriate training decisions and helps reduce risks associated with unsuitable exertion.
When matched to the individual and the program’s goals, appropriate intensity can contribute to improved cardiorespiratory fitness and functional capacity. It may also support disease management and rehabilitation progress. Monitoring intensity remains important because both excessive and insufficient exertion can reduce the suitability of the program, making adjustment central to safe and useful exercise planning.
