The maximal oxygen uptake (V̇O2peak) test is an approved pre-operative examination tool, in a clinical setting: Both V̇O2peak and anaerobic threshold indicate a patient’s physiological tolerance for major surgery and post-operative mortality, with cycle ergometry being routinely used for V̇O2peak tests in clinical settings, in many European countries. Nevertheless, the opportunities to assess populations with restricted mobility of the lower limbs are limited, as alternative methods (such as an arm-crank test protocol) to assess V̇O2peak are yet to be established. Twelve sedentary middle-aged adults (55.1 ± 5.0 years) performed two incremental protocols on an arm crank and cycle ergometer on separate occasions. During exercise, gas exchange was collected and analysed by an online breath-by-breath analysis system. Regression analysis showed that the model with dependent variable cycle ergometer V̇O2peak (CEV̇O2peak) in ml·kg-1·min-1 and independent variables arm crank V̇O2peak (ACEV̇O2peak) in ml·kg-1·min-1, lean body mass lower limbs (LBMLL) and total lean body mass (TLBM) fitted the population the best, with r2 = 0.87, adj. r2 = 0.82 and SEE = 3.14. The equation estimated with this model is: CE V̇O2peak = 11.776 + 1.418 X ACE V̇O2peak(ml·kg-1·min-) – 1.454 x TLBM + 3.967 X LLLBM. Our study suggests that arm cranking could be an alternative mode of exercise for sedentary middle-aged adults (and potentially in clinical settings) to assess the cardiorespiratory fitness of people with restricted lower-limb mobility.

           Key Points
  • Arm cranking could be used as an alternative mode of exercise to assess VO2peak in older adults with restricted lower limbs mobility.
  • Lean body mass has been demonstrated to be as one of the essential predictive variables for the cycling VO2peak prediction by using the physiological responses from the arm cranking. That indicates the strong relationship of the musculature with the cardiorespiratory system in VO2peak tests.
  • ACE elicited a VO2peak (L·min-1) approximately 29% less than cycling and 41% when adjusted for body weight (ml·kg·min-1) which is corollary to the involvement of smaller muscle groups in arm cranking.
