Using unsupervised machine learning to characterize recovery patterns in elite canoe-kayak athletes across the Olympic training year
Foucaud, A., Durand, F., Meric, H.Published in Frontiers in Sports and Active Living (2025)“…Conclusion: Integrated sleep architecture is the dominant discriminator of nightly recovery state, while elevated respiratory rate flags residual metabolic strain. Stable season-long physiological signatures align closely with competitive success, underscoring the value of personalized, ML-driven recovery monitoring in high-performance sport. …”

An all-out sprint does not challenge the main goal of an endurance-based training session in cycling
Demay, R. S., Kerhervé, H. A.Published in European Journal of Applied Physiology (2025)“…Conclusion A 3MAOT performed during an endurance-based training session did not alter metabolism or perceived exer tion, nor did it affect delayed exercise capacity beyond the effect of the 3-h prolonged exercise itself. …”

Preserved fuel mix in spite of increased metabolic rate and lactate steady state at higher cycling cadence
Beneke, R., Leithäuser, R. M., Peters, K., Beier, T., Caputo, F.Published in International Journal of Sports Physiology and Performance (2025)“…Conclusions: The lack of evidence for a cadence effect on relCHO supports the suggestion that a higher cadence enables a lower CHO at given metabolic demand and given BLC, particularly at lower exercise intensity. …”

Performance prediction criteria based on yearling training cycle data for world-class athletes` tiny 1000-meter kayak teams: A case study
Dadelo, S., Nekriošius, R., Dadeliene, R.Published in Life (2025)“…Results: A certain intensity and duration of training effort during preparatory cycles (approximately 22-42% in the third intensity zone, 24-28% in the fourth intensity zone, and 3-4% in the fifth intensity zone) were necessary for athletes to achieve a high level of aerobic metabolism (64.00 and 69.40 mL·min-1·kg-1). Heart rate, work capacity at the second ventilatory threshold, the critical intensity limit, and maximum oxygen consumption were all shown to be vital indicators for predicting competition results. …”

Breath-by-breath measurement of respiratory frequency and tidal volume with a multiple-camera motion capture system during cycling incremental exercise
Massaroni, C., Nicolò, A., Lopes, A.L.d.C., Romano, C., Pinnelli, M., Sarro, K., Schena, E., Cerveri, P., Sacchetti, M., Silvestri, S., Silvatti, A. P.Published in Sensors (2025)“…Fourteen well-trained cyclists performed an incremental step test on a cycle ergometer, while simultaneously recording a raw flow signal with a reference metabolic cart (COSMED) and respiratory-induced torso movements with twelve optoelectronic cameras registering the position of 32 markers affixed to the torso. f and V were calculated from both systems on a breath-by-breath basis. …”

The fourth dimension: physiological resilience as an independent determinant of endurance exercise performance
Jones, A. M.Published in Journal of Physiology (2024)“…For example, the `critical power` (CP), which is a composite of the highest achievable steady-state oxidative metabolic rate and efficiency (O2 cost per watt), may fall by an average of 10% following 2 h of heavy intensity cycle exercise. …”
