“…If mean steady state heart rate (submaximal heart rate) at the end of the test was over 110 bpm, the test was ended. If the submaximal heart rate was below 110 bpm, the workload was increased, and the test continued for another 6 min, if tolerated by the participant (Cink and Thomas 1981). The Astrand nomogram was used to calculate physical fitness (in milliliter per kilogram per minute) from submaximal heart rate, workload, body mass, and gender (Astrand and Rodahl 1986).…”

Relative and absolute muscle mass and muscle strength are used as diagnostic criteria for sarcopenia. We aimed to assess which diagnostic criteria are most associated with physical performance in 180 young (18-30 years) and 281 healthy old participants (69-81 years) of the European study MYOAGE. Diagnostic criteria included relative muscle mass (total or appendicular lean mass (ALM) as percentage of body mass), absolute muscle mass (ALM/height squared and total lean mass), knee extension torque, and handgrip strength. Physical performance comprised walking speed, Timed Up and Go test (TUG), and in a subgroup physical fitness. Diagnostic criteria for sarcopenia and physical performance were standardized, and the associations were analyzed using linear regression models stratified by age category, with adjustments for age, gender, and country. In old participants, relative muscle mass was associated with faster walking speed, faster TUG, and higher physical fitness (all p<0.001). Absolute muscle mass was not associated with physical AGE (2014) performance. Knee extension torque and handgrip strength were associated with faster walking speed (both p≤0.003). Knee extension torque was associated with TUG (p=0.001). Knee extension torque and handgrip strength were not associated with physical fitness. In young participants, there were no significant associations between diagnostic criteria for sarcopenia and physical performance, except for a positive association between relative muscle mass and physical fitness (p<0.001). Relative muscle mass, defined as lean mass or ALM percentage, was most associated with physical performance. Absolute muscle mass including ALM/height squared was not associated with physical performance. This should be accounted for when defining sarcopenia.

“…For example, the Astrand cycle ergometer test is a simple steady state test lasting only 6 minutes, in which peak VO 2 is estimated using a simple nomogram. 7 For a review of other measures of aerobic capacity, the readers are referred to the Noonan and Dean 15 article. If therapists wish to conduct submaximal tests in a clinical setting, they are encouraged to follow ACSM standards, including maintaining strict emergency procedures.…”

As consumer access to physical therapy practice expands, it is important that physical therapists are familiar with and implementing accepted methods of identifying the cardiovascular status of their clients. Established guidelines for assessing cardiovascular risk prior to initiating aerobic exercise programs are available and can be readily adopted by physical therapists in diverse clinical settings. We have provided a process for integrating existing guidelines into clinical practice. Because little evidence exists regarding the clinical behaviors and knowledge of orthopedic physical therapists in the area of cardiovascular risk, we conducted a survey to assess current practice patterns. The results suggest that orthopedic physical therapists are performing cardiovascular screening at frequencies similar to other components of the history and systems review, but that monitoring baseline or exercising vital signs does not occur with every exercise session.

“…1) are represented by a third-order regression equation with two inflection points (high and low blood pressures). Previous studies 1,10) have shown that SBP during an exercise tolerance test increases slightly at a small intensity, there tends to increase rapidly when the exercise intensity rises above a certain level, but the increase is suppressed when the blood pressure is excessively elevated. This suppression of the increase is considered to be due to th e excitation of baroreceptors, which are enhanced to inhibit sympathetic nerve activity.…”

“…The predicted VO 2 max was calculated from the regression line of load and HR and was calculated according to the formula 12.47 × physical work capacity (PWC) ÷ body weight (kg). PWC is defined as the exercise intensity at maximal heart rate 10,11) . This is one of the physical characteristics of the subjects.…”

Abstract. Privious studies have used an exercise stress testing blood pressure (BP) monitor to detect the double product break point (DPBP). However, not all clinical sites of physical therapy are equipped with an exercise stress testing BP monitor. Digital automatic blood pressure monitors (portable sphygmomanometer), which come in more compact, portable models, are becoming more common at general clinical sites. The purpose of this study was to investigate whether a portable sphygmomanometer can be used to derive the DPBP in healthy adults. Exercise stress tests were conducted on 11 healthy adults (8 male, 3 female), using a portable sphygmomanometer and ergometer. To investigate the double product (DP) reproducibility in derivation of DPBP by the portable sphygmomanometer, we repeated the exercise trials within one week. Moreover, using an exercise testing BP monitor, the exercise stress protocol was conducted again within 3 weeks under the same conditions. The results show that DP at DPBP calculated from measurements with a portable sphygmomanometer in the first and second exercise trials with the portable sphygmomanometer were 17084.9 ± 1109.4 and 17131.1 ± 979.2 mmHg × bpm, with an intraclass correlation coefficient of 0.84. The DP at DPBP calculated using measurements from an exercise stress testing BP monitor was 17533.9 ± 1459.2 mmHg × bpm, and the correlation coefficient with the DP value of the second trials with the portable sphygmomanometer was r = 0.80. The results of this study suggest that a comparatively accurate DPBP can be derived using a portable sphygmomanometer.
