Water cycling may offer joint-friendly maximal testing alternatives; leaves open effects on training adaptations and clinical populations.

Key Points

To compare maximal and submaximal physiological responses and thermal comfort during cycle ergometer tests performed on land and in water at different temperatures (27 °C and 31 °C) and cadences.
Ten young men completed maximal exercise tests across separate days in three conditions: land cycling, water cycling at 27 °C (WC27), and water cycling at 31 °C (WC31).
Submaximal physiological responses were evaluated across four cadences (60, 70, 80, and 90 rpm) during the water protocols.
Measurements included blood lactate (BL) concentration, heart rate (HR), oxygen uptake (VO2), ventilation (VE), and thermal comfort (TC).
Maximal HR and VO2 were comparable between conditions, with HRmax values of 189 ± 7 bpm (Land), 188 ± 14 bpm (WC27), and 185 ± 9 bpm (WC31), and VO2max values of 4.2 ± 0.4 l min(-1) (Land), 4.1 ± 0.5 l min(-1) (WC27), and 4.3 ± 0.5 l min(-1) (WC31).
Maximal blood lactate was significantly lower during water protocols than on land (p=0.018), while all submaximal physiological responses increased significantly with every 10 rpm increase from 60 to 90 rpm.
Thermal comfort was significantly affected by pool temperature (p=0.001), with subjects reporting greater comfort at 27 °C (TC: 7 ± 1) compared to 31 °C (TC: 9 ± 1).

Structured PICO

Does water cycling at different temperatures and cadences alter physiological responses compared to land cycling in young men?

Population

10 young men

Intervention

Maximal test on water cycling in an indoor pool at 27 °C (WC27) and at 31 °C (WC31), and submaximal cycling at cadences of 60, 70, 80, and 90 rpm

Comparator

Maximal test on land cycle ergometer

Outcome

Maximal physiological responses including blood lactate, heart rate, oxygen uptake, ventilation, and thermal comfortsurrogate

Water cycling elicits similar maximal heart rate and oxygen uptake as land cycling but results in lower maximal blood lactate levels.
