I Tried Zone 2 Training for 3 Months. This HappenedEnhanced respiratory fitness -
Proposed interval training protocol targeting an aerobic zone for an averaged model. In order to verify the new proposed interval training protocol shown in Figure 3 , more subjects need to be recruited, and this will be the next step of this study.
Before verifying this protocol by experiment, we tested it by simulation first. Switching RC circuit as shown in Figure 4 was used to simulate both HR and VO 2 responses. Designed RC circuit that can be used in simulating HR and VO 2 responses to interval training protocol.
The parameters of the model are tuned based on Table 4. R On multiplied by C R On ×C represents the time constant for the onset response, while R Off multiplied by C R Off ×C represents the time constant for the offset response.
The gain value can be controlled by manipulation of the voltage sources V On and V Off. It should be noted that when the steady state gains of the onset and offset dynamics are approximately the same, V On will be constant and V Off is constant zero.
As another special case, if both the onset and offset exercises reach steady state, then both V On and V Off can be constant. The switch is utilized to replicate the switching behavior between the two responses based on the training protocol segments. National Instruments Multisim has been used to simulate the proposed interval training protocol.
New male subject Subject No. Experimental results for subject 9 are shown in Figure 5. HR and VO 2 experimental results for subject No. The experimental results approximately match the simulation results.
However, in contrast with HR, the experimental results for VO 2 were skewed due to the presence of extensive noise. As the intensity of this protocol is anticipated in the moderate range for the purpose of improving cardiovascular fitness, the relationship between HR and VO 2 is nearly linear [ 2 ].
Furthermore, HR is easier to be measured and has wider frequency bandwidth. Therefore, HR is suitable and therefore recommended to be used as an indicator of exercise strength for the proposed interval training protocol.
The proposed interval training protocol is based on the established average model for eight healthy young male subjects. However, for an individual exerciser who is young and healthy the proposed protocol may need to be adjusted due to the differences of the intra- and inter-subjects.
In this section, we present a hybrid system model a dynamic system that exhibits both continuous and discrete dynamic behaviors to describe the adaptation process and propose a multi-loop PI Proportional and Integral control approach for the tuning of interval training protocol.
The adaptation process is a set of successive interval training experiments for a particular user. This process can be described by using a hybrid system model [ 26 ]. Specifically, each single experiment can be considered as a discrete event and the dynamics of cardio-respiratory responses to exercise can be depicted by a continuous linear model.
It will be shown under modest assumptions, we can simplify this special hybrid system as a simple discrete time system. The intermission between the interval training experiments can be hours or days. However, in order to simplify the process, we first assume that the intermission is constant similar as the sampling time of a discrete time system given that the subject has similar physiological conditions before each training i.
In order to simplify the system as a static discrete time system, we first pick up some key characteristics from the continuous processes, which are associated with exercise effects, such as mean value and standard deviation. The proposed training protocol see Figure 3 contains three-period square wave.
In this study we pick up the lowest point and the highest point of the third period HR response y t 4 and y t 5 respectively as the reflections of exercise effects see Figure 6. Under the above assumptions and simplification, the overall adaptation process can now be simply treated as a two-input two-output 2I2O discrete time system.
In order to determine the model of the 2I2O static system, we investigate HR response for the proposed interval training protocol. Figure 6 shows the protocol and its response.
Based on the previous model, the outputs y t 4 and y t 5 can be obtained as follows:. Where k 1 , k 2 , T 1 and T 2 are the onset, offset gains and time constants respectively, and. Figure 7 is the block diagram of the proposed control system.
Two discrete PI controllers C 1 and C 2 have been built and connected to the HR model to control the desired output values y t 4 and y t 5 separately. The controller parameters the coefficients of P and I actions of these two simple multi PI controllers are tuned by trial and error.
We simulated the control performance in Matlab Simulink. Multi-loop PI control system to regulate output values y t 4 and y t 5. Up to now, we can see even though our aim is to regulate a continuous process; we proposed a simple discrete time control technique to fulfill the goal.
During interval training of an individual subject, at the first iteration the exerciser is asked to run under the predefined training protocol.
This modification will try to adjust the measured output values y t 4 and y t 5 to approach the desired setpoints for the next training exercise. This recursive process will be repeated until we finally reach the desired set points.
The self-adaption feature gives the exerciser the opportunity to reach his desired setpoints after a number of iterations.
Figure 8 below shows the simulated controller outputs, y t 4 and y t 5. Simulation results of PI control system outputs. Offset output signal y t 4 of HR response a and onset output signal y t 5 of HR response b.
In simulation, from Figure 8 , we conclude that after at least 12 iterations 12 training exercises the system will reach the desired setpoints. In other words, t 4 and t 5 have to be observed 12 times and re-entered to the controller to achieve the desired outputs.
Figure 9 below shows the HR response for the 13 th iteration. The third waveform in Figure 9 shows that the output signal finally reached the desired reference values R 1 and R 2 at t 4 and t 5 respectively.
Continuous interval training HR response simulation from the controller. Since our controller is based on discrete events regulating a continuous process, it can perform one time between two training experiments.
Therefore, it is very easy to be implemented in low cost portable devices which have limited computation power. This section provides a practical method to examine and verify the functionality as well as performance of the proposed controller. The new interval training protocol combined with the designed controller have been implemented and tested on stair climbing exercise as a free environment activity.
This can show how the proposed interval training protocol that has been created earlier can be implemented using different exercising techniques, such as stairs climbing, cycling and even swimming. The setup, concept and structure of the interval training remain the same.
However, the change would be within the type of exercise during the onset and offset stages. Subjects in the new implementation will be requested to ascend a staircase of steps without any pause; the exercisers will attempt to achieve the training protocol without holding the banisters or the handrail.
The experiments were carried out at free speed and the participants were given the instruction to walk at their normal pace. This will represent the onset stage in our training protocol.
On the other hand, offset stages can be represented as walking aside on the same step the exercisers reach when the onset period finishes; this continuous walking on the same step is the perfect match of the offset stage in the treadmill interval training exercise.
All participants were instructed to use their left legs for the first step, to only place one foot on each step foot-over-foot ascent and to continue walking in straight line.
Based on the simulation results in the previous section, the exerciser needs 12 iterations to reach his desired setpoints. Practically, the experiments results for a new male subject Subject No.
In the first iteration, 60 seconds is set to be the onset and offset times. Accordingly, the controller adjusts the time of onset and offset periods for the next training session.
Table 7 shows the controller parameters and their corresponding experimental results for Subject No. HR response after the first iteration a , HR response after the second iteration b and HR response after the third iteration c.
Referring to the results from Table 7 and Figure 10 , we can conclude that the exerciser has almost reached his desired setpoints after only 3 iterations, when the simulation results showed that it can be done after 12 iterations.
This shows how our controller has accomplished its duty with minimum number of iterations. It is worth mentioning that for a proposed training regime based on an averaged model; we expect each subject to respond differently to a particular exercise or training protocol, of interest was Subject 10 who reached his desired set points after only three iterations.
We may reach the desired set points or a steady state for another subject after 10, 11 or even 12 iterations, it depends totally on the intra- and inter- model uncertainties. During the study, it was considered that after a certain number of training sessions, the training capacity of the subject will improve and this may affect the result of his HR response.
In the next step of the study, we will recruit more subjects in order to verify our results and to even improve the performance of our controller.
A designed square-wave exercise protocol was applied to investigate the dynamic characteristics of HR and VO 2 responses for both the onset and offset exercises.
The K 4 b 2 portable device was used to measure breath-by-breath VO 2 and beat-by-beat HR. According to the experimental results, it was concluded that the time constants and steady state gains of the onset exercise for both HR and VO 2 are distinctively different with those of the offset exercise.
Based on the identified dynamic characteristics for both HR and VO 2 , we proposed an interval training protocol to improve cardiovascular fitness. A switching RC circuit model was presented to simulate HR and VO 2 responses for the proposed interval training protocol.
In order to adapt to individual users, a multi-loop integral control scheme has been proposed to regulate the HR response for interval running exercise under free living conditions.
In the next step of the study, we will recruit more subjects for the validation of the proposed models, interval training protocol and the feedback control based adaption scheme. Acharya R, Kumar A, Bhat IP, et al.

Jeremy Barnes, an associate professor of health management at Southeast Missouri State University, explains. Regular exercise leads to numerous and varied physiological changes that are beneficial from a health standpoint.
They include improved cardio-respiratory function and skeletal muscle function; higher levels of high-density lipoprotein cholesterol the so-called "good" cholesterol ; improved blood pressure, body composition, and bone density; decreased insulin need and improved glucose tolerance; enhanced performance of work, recreational and sport activities; and many positive psychological benefits.
These changes, in turn, help lower death rates from illnesses such as cardiovascular disease including heart attack and stroke ; type-2 diabetes; and certain cancers, including colon, breast and lung; and lower disease rates for high blood pressure, obesity, osteoarthritis and osteoporosis.
Because of the many benefits of physical activity and exercise, the federal government now encourages all adults to increase their physical activity levels so they accumulate 30 minutes, or more, of moderate instensity physical activity most days of the week. Improved cardio-respiratory function means that the body is able to perform exercise much more efficiently.
This results mainly from the body more effectively getting oxygen into the blood stream and transporting it to the working muscles, where it is needed for the metabolic processing of energy.
In other words, the regular exerciser's body is much more proficient at loading, transporting and utilizing oxygen. He thus finds exercise such as climbing stairs far less strenuous than a person who does not exercise and is out of shape.
Improvement in cardio-respiratory function does not result from changes in the lung's ability to expand, however. In general regular exercise does not substantially change measures of pulmonary function such as total lung capacity, the volume of air in the lungs after taking the largest breath possible TLC , and forced vital capacity, the amount of air able to be blown out after taking the largest breath possible FVC.

As these body's functions are vital to an individual's health, CRF allows observers to quantify an individual's morbidity and mortality risk as a function of cardiorespiratory health. Regular physical activity and exercise can improve CRF, thus decreasing risk of CVD and other conditions while improving overall health. The emergence of a method to quantify CRF began in the s when Archibald Hilla British physiologist, proposed a multifactorial relationship between the maximum rate of oxygen uptake by body tissues and intensity of physical activity. This proposal ignited a multitude of studies demonstrating a relationship between VO 2 max and cardiovascular disease and all-cause mortality.

VO 2 max is the most commonly accepted indicator of CRF and has been since the s. It requires the individual to perform exercise with analysis of gas exchange usually until maximal exertion is achieved.
The use of electrocardiography is often used to examine heart response to exercise and exertion. In many cases, children or the elderly are not subjected to the vigor of cardiopulmonary exercise testing. There are other methods used to mathematically estimate the VO 2 max of a test subject by having the subject walk or jog a certain distance in as little time as possible, complete the maximum number of repetitions of a short-distance run commonly known as the PACER test in the United States , or walk on a treadmill at increasing incline until a sub-maximal goal is achieved, along with others.
In general regular exercise does not substantially change measures of pulmonary function such as total lung capacity, the volume of air in the lungs after taking the largest breath possible TLC , and forced vital capacity, the amount of air able to be blown out after taking the largest breath possible FVC.

Cardiac output is a major limiting factor for prolonged exercise. In addition, an exerciser typically has a larger blood volume, is better able to extract oxygen from the air in the lungs and is better able to extract oxygen from the blood at the working muscles than a sedentary individual is.
Gas exchange involves not only oxygen delivery but also the removal of carbon dioxide, which is a byproduct of energy metabolism, and this process is also more efficient in an exerciser. When all is said and done, regular exercise produces numerous favorable changes that collectively result in the body being able to work in a far more efficient manner.
All of us are born with the ability to increase our physical fitness levels through regular exercise so it is unfortunate that many peoples' sedentary lifestyles and lack of exercise result in unfavorable outcomes in terms of disease.
Exercise and Lung Health. Section Menu. How Does Exercise Strengthen the Lungs? The Benefits of Exercise Exercise has lots of benefits for everyone, whether you are young or old, slender or large, able-bodied or living with a chronic illness or disability.
What Types of Exercise and How Much? Some Things to Keep in Mind Always talk to your doctor before you start or modify your exercise routine. This is especially important if you have an underlying health condition. Avoid exercising outdoors when pollution levels are high.
