This article discusses the ratings of perceived exertion (RPE) scales and how to educate older clients to utilize them, as well as how to monitor and safely progress their training intensity.

This article reviews the use of heart rate as a way to program cardiovascular exercise.

The purpose of this article is to discuss the health and occupational implications of firefighters not currently meeting the National Fire Protection Association (NFPA) aerobic capacity recommendations.

The loading intensity a person chooses depends on his or her goals and training status (i.e., whether the person is a trained athlete or a sedentary individual). Ultimately, the number of repetitions you can perform at a given intensity or load determines the effects of training on strength develop.

This article discusses the importance and impact a qualified fitness professional on the fitness and readiness of soldiers for the United States Army.

The 3-minute all-out exercise test (3MT) was developed over a decade ago and enables the estimation of time for onset of momentary fatigue for a given speed or power output exceeding critical speed (CS) or critical power (CP), respectively. The 3MT has been validated for conducting high-intensity interval training, used with load carriage prediction and prescription, and validated for shuttle running. These prescriptions are novel because they allow for standardizing exercise intensities relative to metabolic parameters as opposed to a percentage of a given maximum or reserve. Research was identified using leading search engines (e.g., PubMed, Google Scholar, and Research Gate) and citations to similar articles. The objective of this review article was to summarize research that emerged on the CS/CP concept with emphasis on applications since the advent of the 3MT. The review concludes with application of the CS/CP concept to the frequency, intensity, time, and type of exercise for exercise prescription.

The goal of this brief review is to describe what classifies as high-intensity interval training (HIIT) and summarize the potential benefits for various populations: athletic, general, and clinical.

Lifestyle modification, including exercise, is important for both preventing and treating hypertension. More recent guidelines for treating hypertension have increased emphasis on lifestyle factors, such as exercise. As fitness professionals, it is important to educate and encourage clients with hypertension on the importance of exercise in their overall health.

High-intensity strength training paired with explosive, high-velocity movements is suggested to enhance endurance performance. It is recommended that a practical approach be taken when implementing this model of strength training, which would involve a thorough preparatory period.
