what are the relationship between physical fitness and heart rate

The relationship between heart rate and fitness level is variable for individuals. The ability How is breathing related to your level of physical fitness? Why does . Download scientific diagram | Relationship between physical fitness (VO2Max) and resting heart rate (bpm). from publication: Elevated resting heart rate. Psychologist, physical fitness buff, business consultant and writer If you want to determine your maximum heart rate, or the maximum number of times your heart can beat per minute, subtract your age from . Relationships.

However, many people prefer workouts that are not this intense but still effective. They might want to target percent of the maximum beats for their age as an ideal number.

Still others like to vary their workout intensity from day to day or even within the same workout, such as walking a bit, then jogging a bit, then walking and so on. Whatever works for you is best.

However, workouts less than 60 percent of the maximum for your age may not be intense enough to promote good cardiovascular fitness. Well, it's a quick indicator of how fit you are. The average person has a resting pulse rate of between 70 and 75 beats per minute.

Fit people who get lots of aerobic exercise having resting pulse rates in the 50s and 60s.

Some professional athletes have resting pulse rates as low as the upper 30s. On the other side, unfit people have resting pulse rates of 80, 90 or more beats per minute.

Any of you who take up regular aerobic exercise will notice that your resting pulse rate will drop over time -- meaning that your heart does not have to work as hard and beat as many times per minute to get nutrients and oxygen distributed to all of your body.

The best time to measure your resting pulse rate is when you first wake up in the morning and are still in bed. Even light walking will cause the heart to beat a little faster, and drinking coffee or soda with caffeine will artificially raise your pulse rate by a great deal.

During the night, your body flushes out most caffeine, so taking your pulse the next day is the best true indicator of your resting pulse rate. If you have ever had a cardiac stress test done, this test is controlled by your heart rate.

You are initially at rest on a treadmill with an apparatus hooked up to you, which monitors your heart rate and provides EKG readings, among other things.

Resting heart rate and the association of physical fitness with carotid artery stiffness.

The treadmill is gradually increased in both speed and incline. This continues until you reach a heart rate that's 80 percent of the maximum for someone of your age. Then the test stops. People who are sedentary and unfit might get to their maximum in less than 5 minutes of very slow walking. A very fit runner might be on the treadmill for 30 minutes, and at the end of the test the treadmill forces the person to run fast and the incline is high.

So the stress test determines how fit you are in addition to abnormalities in your heart.

Association between Resting Heart Rate and Health-Related Physical Fitness in Brazilian Adolescents

There's been some thinking among researchers that your heart has only so many beats in it. It will beat a certain number of times and no more. The questionnaire was answered in the classroom, and data were self-reported by students. Participants were informed about the procedures and instructed to remain at rest for at least five minutes, in a quiet and calm environment, with empty bladder, without having exercised for at least 90 minutes before evaluation, not having smoked and not having consumed alcohol, coffee, or tea at least 30 minutes prior to data collection.

Measurements were performed twice at intervals of fifteen minutes.

For this research, the average beats per minute bpm rate of the two measurements was used. RHR was measured on the same day of the aerobic fitness test; however, it was performed before the aerobic fitness test. For purpose of analysis, RHR was treated as a continuous measure. Aerobic fitness was measured using the modified Canadian Aerobic Fitness Test mCAFT [ 17 ], validated in comparison to indirect calorimetry in Canadian men and women aged 15—69 years [ 18 ], and with sufficient discriminatory power to detect high blood pressure levels in young Brazilians [ 19 ].

Adolescents had to complete one or more stages of three minutes each going up and down two steps with increasing intensity at predetermined rates according to sex and age.

In order to estimate VO2peak the equation We chose this classification because there are no criterion-referenced cut-points for this physical test for the Brazilian population. During evaluation, participants remained standing with arms outstretched at the side of the body, with the hand and dynamometer not touching the body. The device was individually sized between the distal phalanges and the palm of the hand, and the adolescent was asked to take maximum inspiration and expiration, followed by a maximal effort to squeeze the dynamometer [ 17 ].

The test was performed on both hands alternately, twice, and the best result of each hand was recorded in kilograms kg and summed, obtaining the total force. Flexibility was measured using the Wells bench for the sit-and-reach test [ 20 ]. The test was performed twice and the highest value reached in the test was used [ 17 ]. Body fat was evaluated using the sum of two skinfold thicknesses.

Anthropometric measurements were performed by a single evaluator with level one ISAK certification. For the present study, the sum of the two skinfolds thickness values was used. Sociodemographic, physical activity, sexual maturation, and BMI variables were included in the analyses as control variables.

Sexual maturation was self-assessed by adolescents, using maturational development boards proposed by Marshall and Tanner [ 24 ].

These boards contained photographs of the five stages of maturational development, with adolescents being asked to look closely at each photograph and to mark in the questionnaire which photograph most resembled their genital organ size for boys and breast size for girls. Students were individually oriented by same-sex evaluators about the objective and importance of this evaluation.

Weight and height measures were collected to calculate the BMI. BMI z-scores were computed using age- and sex-specific reference data from World Health Organization [ 25 ]. Descriptive and inferential statistical procedures were used, and data normality was verified through mean and median comparison, skewness, kurtosis, and graphs.

For the description of continuous variables, mean and standard deviation were used. Student's t-test was used to identify differences between variables according to sexes.

For categorical variables we used Chi-square test. In the adjusted analysis between RHR and models with each health-related physical fitness indicator, sociodemographic variables sex and agephysical activity, sexual maturation, and BMI were inserted as control variables. Residuals from the final multiple linear regression models were assessed by heteroscedasticity and normality. In addition, the interaction between covariates age, physical activity, sexual maturation, and BMI and physical fitness variables was verified.

As there was no interaction between variables, analysis of covariance ANCOVA was used stratified by sex in order to verify if there were differences in RHR according to the categories in tertiles of health-related physical fitness components.

In all analyses we calculated the effect size as recommended by the literature [ 2627 ]. Statistical analyses were performed using Stata
