Maximal oxygen uptake (VO2max) during a graded maximal exercise test is the objective method to assess cardiorespiratory fitness. Maximal oxygen uptake testing is limited to only a few laboratories as it requires trained personnel and strenuous effort by the subject. At the population level, submaximal tests have been developed to derive VO2max indirectly based on heart rate based nomograms or ...

BACKGROUND Participation in aerobic exercise generates increased cardiorespiratory fitness, which results in a protective factor for cardiovascular disease and all-cause mortality. High-intensity interval training might cause higher increases in cardiorespiratory fitness in comparison with moderate-intensity continuous training; nevertheless, current evidence is not conclusive. To our knowledge...

PURPOSE We examined the reproducibility of performance and physiological responses on a squash-specific incremental test. METHODS Eight trained squash players habituated to procedures with two prior visits performed an incremental squash test to volitional exhaustion on two occasions 7 days apart. Breath-by-breath oxygen uptake (Vo2) and heart rate were determined continuously using a portabl...

Background. Maximal Aerobic Power is related to many quantities and qualities such as supplements. Objectives. The purpose of the present study was to describe the effect of short-term supplementation of glutamine and glucose on hemoglobin and maximum aerobic power in female athletes. Methods. In this quasi-experimental study, 40 female athletes (age 21.9±2.6 years, height 161.8&...

The present study investigated the rate of systolic blood pressure recovery (SBPR) amongst three male age groups. Ninety-six apparently healthy, non-athletic adult males (48 young [23.91±4.58 years], 32 middle-aged [41.78±5.98 years] and 16 elderly [62.87±2.57 years]) participated in the study. Subjects performed a maximal-effort ergometer exercise test. Maximal oxygen uptake (VO2max) was measu...

OBJECTIVE To examine the cardiorespiratory response to exercise in healthy South Indian school children. DESIGN Prospective study. SETTING Cardiopulmonary Medicine Unit, Tuberculosis Research Center, Madras. SUBJECTS Data was obtained on 47 girls and 48 boys in the age group 7 to 14 years. INTERVENTION The children performed a graded maximal exercise stress test on a computerized treadm...

BACKGROUND Aerobic fitness is of great value for reducing risk of mortality and cardiovascular diseases. OBJECTIVE This study evaluated the performance in and correlations between a new test (five-minute pyramid test, 5MPT), the six-minute walk-test (6MWT) and maximal oxygen uptake (VO2max) among old and young adults. METHODS Forty-four habitually active adults (females and males), 23 old (...

The purpose of this study was to examine the metabolic and cardiovascular response to exercise without (CON) or with (BFR) restricted blood flow to the muscles. Ten young men performed upright cycle exercise at 20, 40, and 60% of maximal oxygen uptake, VO2max in both conditions while metabolic and cardiovascular parameters were determined. Pre-exercise VO2 was not different between CON and BFR....
