Perceived and Heart Rate-based Intensities during Self-paced Walking: Magnitudes and Comparison.

There is limited research on self-paced walking and whether healthy individuals reach perceived exertion- (RPE) and/or heart rate- (HR) based moderate intensities. Study purpose was to determine if achieved RPE and HR intensities during a self-paced walk are of equivalent magnitude and whether they reach the recommended moderate-intensity. Thirty participants completed a 15-minute self-paced walk.

Variability of Competition-Based Caloric Expenditure and Relative Heart Rates in National Collegiate Athletic Association Division I Women's Basketball.

Sanders, GJ, Boos, B, Rhodes, J, Peacock, CA, Kollock, RO, and Scheadler, CM. Variability of competition-based caloric expenditure and relative heart rates in National Collegiate Athletic Association Division I women's basketball. J Strength Cond Res 36(1): 162-166, 2022-Basketball athletes frequently engage in high intensities (≥85% HRpeak) throughout competition, and it is unknown how high-intensity play coincides with caloric expenditure and average and peak relative heart rates.

Validity of the Wattbike 3-Minute Aerobic Test: Measurement and Estimation of V̇o2max.

Hanson, NJ, Scheadler, CM, Katsavelis, D, and Miller, MG. Validity of the Wattbike 3-minute aerobic test: measurement and estimation of V̇o2max. J Strength Cond Res 36(2): 400-404, 2022-The Wattbike includes a 3-minute aerobic test (3mAT) along with an estimation of V̇o2max.

Factors associated with minimal changes in countermovement jump performance throughout a competitive division I collegiate basketball season.

The purpose of the study was to assess factors that contribute to countermovement jump (CMJ) performance in women's basketball athletes. Thirteen female athletes participated and were tested for maximal oxygen uptake (VO) and heart rate (HR). Athletes were monitored, daily for a total of 21 weeks with heart rate-based wearable devices and CMJ performance and body weight were tested weekly after one day of recovery.

Simulated Altitude via Re-Breathing Creates Arterial Hypoxemia but Fails to Improve Elements of Running Performance.

Acclimatization to altitude has been shown to improve elements of performance. Use of simulated altitude is popular among athletes across the sports spectrum. This work was on a handheld, re-breathing device touted to enhance performance.

Pacing strategy during the final stage of a self-paced V̇O₂max (SPV) test does not affect maximal oxygen uptake.

Purpose: Self-paced [Formula: see text] tests (SPVs) have shown to produce maximal oxygen consumption values similar to those from traditional protocols. These tests involve perceptually regulated stages in which subjects are asked to maintain rating of perceived exertion values of 11, 13, 15, 17 and 20 for 2 min each. What is not clear is how the last stage should be paced.

The Gas Sampling Interval Effect on V˙O2peak Is Independent of Exercise Protocol.

Introduction: There is a plethora of gas sampling intervals available during cardiopulmonary exercise testing to measure peak oxygen consumption (V˙O2peak). Different intervals can lead to altered V˙O2peak. Whether differences are affected by the exercise protocol or subject sample is not clear.

Modality determines VO2max achieved in self-paced exercise tests: validation with the Bruce protocol.

Purpose: The Bruce protocol is traditionally used to assess maximal cardiorespiratory fitness (VO2max), but may have limitations, such as an unknown duration and large work rate increases. The use of self-paced VO2max tests (SPVs) may be beneficial if they are able to elicit similar maximal values in a set period of time. In addition, differences in modality between SPVs have not been explored.

VO2max Measured with a Self-selected Work Rate Protocol on an Automated Treadmill.

Purpose: The use of graded maximal exercise tests for measuring maximal oxygen consumption (VO2max) is common practice in both cardiopulmonary rehabilitation settings and in sports medicine research. Recent alterations of common testing protocols to allow for self-selected work rates (SPV) have elicited V˙O2max values similar to or higher than more traditional style protocols (TP). Research is lacking in the delivery of the SPV protocol using a treadmill modality.
