# Relationship between vo2 max and heart rate formula

Literature shows numerous studies modelling the relationship between steady Figure 1. Model of HR-derived VO2-estimation. HR(max) = (maximal) heart rate. The regression analysis of the quadratic equation also indicated that there was also a significant relationship between the VO2 max and HR. VO2 Max is the most accurate measure of cardio-respiratory fitness. It measures the maximum amount of oxygen that the body can use in one minute per.

To continue improving, you need to keep stressing these systems in a healthy way. By designing a workout plan that targets specific heart rate zones, you can improve your endurance, heart rate and speed. Heart Rate Zone Basics Training within specific heart rate zones can help you reach your fitness goals.

The first zone, known as the energy-efficient zone, is 60 to 70 percent of your maximum heart rate and develops basic endurance. The anaerobic zone is 80 to 90 percent of your maximum heart rate and helps your develop your lactic acid system by improving your anaerobic threshold.

This is the point when you are working out so hard that your muscles start to burn, eventually forcing you to slow down. Finally there is the red line zone, which is 90 to percent of your maximum heart rate. Training in this zone helps you build speed.

When you are working out, your muscles are pulling oxygen from your bloodstream. By improving this rate, you can work out at a higher intensity or duration. In a meta-analysis of more than 50 studies, published in "Sports Medicine" inthe authors concluded that workouts performed at 90 to percent of your VO2 max pace bring about the largest improvements in VO2 max performance. This was defined as the slowest pace that you reach your maximum oxygen consumption.

For most people, this falls somewhere between your one-mile race pace and two-mile race pace, or how quickly you would run a mile in a race. The study is aimed to investigate the relationship between the aerobic capacity and the RPE based on the measurement of heat rate HR of workers from the Metal Industries of Isfahan.

The subjects were male workers from metal components manufacturers in Isfahan selected by using random sampling based on statistic method.

The subjects were examined by using ergometer in accordance with A strand 6 minutes cycle test protocol. Furthermore, the subjects were asked to rate their status based on the Borg rating scale at the end of each minute. Additionally, their heat rates were monitored and recorded automatically at the end of each minutes.

The regression analysis of the quadratic equation also indicated that there was also a significant relationship between the VO2 max and HR. To assess the effectiveness of an ergonomic intervention program, the special tools are needed to gather information on the fitness. By assessing the physical and physiological characteristics of human beings, it is possible to assign him to a task on the basis of his physiological tolerance limits.

Currently, the aerobic capacity has been as the maximal capacity to perform the work. Today, scientists believe that the ability to perform physical exercise should be determined using the aerobic capacity.

## What’s the Relationship Between VO2max and Heart Rate?

Direct methods and indirect methods. The direct methods include using the treadmill, ergometer, and step tests, while the indirect methods include charts and formulas of Astrand and physiological e.

It is worth noting that the direct methods are more accurate but more expensive which need training technicians for setting up and using equipments while time consuming; on the contrary, the indirect methods are useful and effective for assessing aerobic capacity in the industries as to have no such limitations.

In order to measure the level of subjective physical workload, the RPE scale proposed by Borg is very useful,[ 6 ] which is a rating scale as to rating scales are important supplemental measures of psycho - physical performance and work capacity.

Furthermore, this scale also has several applications in the field of medicine and ergonomics. Therefore, to prevent early deterioration of workforce resulting in low efficiency, it is needed to determine the fitness between the individual and the work. However, yet there has been no comprehensive study done on the physical exercise capacity of Iranian workers and, as a result, there is no detailed information in this area;[ 91011 ] perhaps because of the high cost of technician training to operate the special equipments of direct methods such as ergometer, which isn't cost-effective and affordable for the industry.
