“…As implemented in this work, an evaluation based on an individual slope is recommended [13]. Concerning the HR, only a small number of studies define a plateau [25,26], whereas others evaluate this criterion based on the age-predicted HR [14,15]. In this analysis, we include both approaches.…”

“…Second, we determined whether a plateau in HR with increases in workload was achieved. This criterion was defined as a change in HR between the final two 30-s intervals (calculated by averaging the respective 15-s averages) of ≤4 beats•min −1 [25,26]. Third, we determined whether a plateau in V ̇O2 was attained despite increases in workload.…”

Background and purpose Valid measurements of cardiorespiratory fitness in persons with multiple sclerosis (pwMS) are essential during inpatient rehabilitation for a precise evaluation of the current health status, for defining appropriate exercise intensities, and for evaluation of exercise intervention studies. We aim (i) to examine the proportion of pwMS who attain the American College of Sports Medicine (ACSM) criteria for maximal effort during graded cardiopulmonary exercise testing (CPET) and (ii) to provide insight into participant characteristics that limit maximal exercise performance. Methods This cross‐sectional study comprises a retrospective examination of ACSM criteria for maximal effort during graded CPET of n = 380 inpatient pwMS (mean age = 48 ± 11 years, 66% female). Chi‐squared or Fisher's exact tests were conducted to compare differences in the distribution of criteria achieved. Participants' characteristics were examined as potential predictors using binary logistic regression. Results Only 60% of the overall sample attained a respiratory exchange ratio ≥ 1.10. With regard to the definition applied, only 24% or 40% of the participants achieved an oxygen consumption plateau, and 17% or 50% attained the heart rate criterion. Forty‐six percent met at least two of three criteria. Disability status, gender, disease course, and body mass index were associated with the attainment of maximal effort. Conclusions Our findings suggest that a relevant proportion of inpatient pwMS do not attain common criteria utilized to verify maximal oxygen consumption. Identified predictors for criteria attainment can be used to create models to predict cardiorespiratory fitness and to optimize CPET protocols in restrictive groups of pwMS.

“…Twenty-four recreationally active (≥150 minutes of moderate to vigorous intensity aerobic activity per week for one or more years) men ( n= 12) and women ( n= 12) participated in this study.

“…The verification trial has been demonstrated to be effective for confirming VO 2 max in older adults [14,15] and obese individuals of low CRF [5]. The verification phase was also demonstrated as a practical and sensitive method to confirm VO 2 max among differ ent populations ranging from highly trained athletes [16], recre ationally trained subjects [17], physically active [18], sedentary [19], obese and overweight [20], clinical populations [21], and even in younger individuals [22].…”

We investigated the effect of cardiorespiratory fitness (CRF) on the probability of achieving the verification criterion to confirm that VO2max was obtained in a sample of middle-aged to older adults. Data from twelve men and nine women (60.7±8.5 years, VO2max: 34.8±9.4 mL/kg/min) were used for analysis. Participants had their VO2max measured via a maximal graded exercise test and confirmed using a verification bout on a cycle ergometer. Logistic regression was used to evaluate the effect of CRF (VO2max) on the probability a participant would successfully achieve the verification criterion. Odds ratios are reported to quantify the effect size. No statistically significant relationship was observed between CRF and achieving the verification criterion (β=.081, SE=.0619, Wald=1.420, p=.156). Estimated odds ratio for the effect of CRF on the verification criterion indicated an increase of 8% [Exp(β)=1.08, 95% CI (0.96, 1.22)] in the probability of achieving the verification criterion given a one unit increase in VO2max. Each 1 mL/kg/min increase in VO2max results in an 8% increase in the chance that an individual achieves the verification criterion confirming that VO2max was obtained. Therefore, CRF is likely of practical significance and should be considered when deciding to use a verification trial.
