Summary
This study suggests using Rating of Perceived Exertion (RPE) and heart rate reserve (HRr) to determine exercise intensities in master elderly athletes. RPE 12-13 and 60% HRr approximate the first ventilatory threshold (VT1), while RPE 15 and 80% HRr approximate the second ventilatory threshold (VT2).
Area of Science:
- Exercise Physiology
- Gerontology
- Sports Science
Background:
- Determining optimal exercise intensities for master elderly athletes is crucial for effective training and health benefits.
- Ventilatory thresholds (VT1 and VT2) are key indicators of exercise intensity but are not easily measured in routine practice.
- Existing methods for assessing exercise intensity may not be practical or accessible for older, trained populations.
Purpose of the Study:
- To propose a practical approach for determining exercise intensities at VT1 and VT2 in master elderly athletes.
- To investigate the relationship between Rating of Perceived Exertion (RPE) and heart rate reserve (HRr) at ventilatory thresholds.
- To provide evidence-based recommendations for exercise prescription in this demographic.
Main Methods:
- Sixteen trained elderly men and 8 trained elderly women (mean age ~62 years) underwent an exhaustive cycle ergometer test.
- Rating of Perceived Exertion (RPE) and heart rate reserve (HRr) were recorded at the first (VT1) and second (VT2) ventilatory thresholds.
- Data were analyzed to compare RPE and HRr values between genders at each threshold.
Main Results:
- No significant gender differences were observed in RPE or HRr at either VT1 or VT2.
- VT1 was associated with an RPE of 12-13 and approximately 60% HRr.
- VT2 was associated with an RPE of 15 and approximately 80% HRr.
Conclusions:
- RPE values of 12-13 and 60% HRr can serve as practical indicators for VT1 in trained older adults.
- RPE values of 15 and 80% HRr are suitable indices for prescribing exercise intensity at VT2.
- These findings offer a simplified method for exercise intensity prescription in master elderly athletes, enhancing training efficacy and safety.

01:17Exercise and Cardiac Output
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

01:20Exercise and Cardiovascular Response
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:27Exercise and Muscle Performance
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:15Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
