We suggest that quantifying load using 3 dimensions rather than one better predicts adaptations specifically in CP, W', and Pmax. Using a global amalgamation of load such as total work, TRIMP, or TSS inevitably leads to more uncertainty about what exact attributes training is targeting.

Accumulating work at different intensities relative to CP, Pmax, and remaining W' results in somewhat distinct adaptive responses, which should be taken into account when trying to model training and predict performance gains.

Our new preprint proposes a new way to quantify training loads based on power output. We describe how a 3-parameter CP model may be used to estimate contributions of each energy system, resulting in a "strain score" which overcomes some limitations of other TL metrics. doi.org/10.48550/arX...

Tom's Weekend Warrior study is out! Training either 4x (short) or 2x (long) weekly resulted in the same adaptations, when overall volume and content of training was fixed.

Performance, thresholds, efficiency, Hbmass, and ox cap ↑ equally in both groups.
