Journal Article
Bossi, A. H. (in press). Time to retire the raw analysis of individual responses. Communications in Kinesiology,

This letter critiques the data analysis of a study investigating peak oxygen uptake responses to cycling and running sprint interval training (Digby et al. 2023 J Strength Cond Res, 37(4), e313-e316). While the study effectively demonstrates the spec... Read More about Time to retire the raw analysis of individual responses.

Adding intermittent vibration to varied-intensity work intervals: no extra benefit (2022)
Journal Article

Varied-intensity work intervals have been shown to induce higher fractions of maximal oxygen uptake during high-intensity interval training compared with constant-intensity work intervals. We assessed whether varied-intensity work intervals combined... Read More about Adding intermittent vibration to varied-intensity work intervals: no extra benefit.

Optimizing Interval Training Through Power-Output Variation Within the Work Intervals (2020)
Journal Article

Purpose: Maximal oxygen uptake (˙VO2max) is a key determinant of endurance performance. Therefore, devising high-intensity interval training (HIIT) that maximizes stress of the oxygen-transport and -utilization systems may be important to stimulate f...
