Determinants of Flatwater Canoeing and Kayaking Performance

Systematic search, narrative synthesis

B+moderate evidenceMeasured on a mixed groupWritten before October 2026, being re-checked

Key Findings (abstract)

Search up to June 2020 in Scopus, SPORTDiscus and Web of Science, canoeing and kayaking treated separately, male and female paddlers
High-level male kayakers and canoeists share a mesomorph build with low body-fat, high lean body mass and strong musculature; kayakers are slightly taller than canoeists
High levels of both aerobic and anaerobic capacity, with distinguished upper-body strength and muscle thickness, especially in the arms and shoulders
Female kayakers follow the same pattern with lower values than males
Conclusion: successful performance depends on a combination of anthropometric, physiological, biomechanical, neuromuscular, psychological and nutritional factors, which differ between specialised kayak and canoe paddlers because of their different paddling motor patterns — physical preparation and talent identification should be modality-specific

Practical Application

Systematic search (to June 2020) of flatwater kayak and canoe determinants: high-level paddlers combine high aerobic AND anaerobic capacity with pronounced upper-body strength and arm/shoulder muscle thickness in a lean mesomorph build; kayak and canoe differ in motor pattern and should be prepared for separately. For a masters paddler: build both energy systems and the upper body specifically to your boat
Cyclist/runner: kayaking = whole-body, non-impact, upper-body-dominant cross-training (kind to legs/joints). Not from this paper; the base's own practice
Stroke rate × stroke length as a fatigue marker is a swimming heuristic (REF-535); this abstract does not report stroke mechanics. Inference, not tested: the analogy is plausible, not shown here

Limitations

Narrative synthesis; heterogeneity of included studies, some with small samples
The abstract gives no numbers (no VO2max, strength or distance-specific values)
Sprint (Olympic) flatwater ≠ marathon/touring paddling — different demands

Why this level

regraded 2026-09-27 from A: systematic search but narrative synthesis of descriptive studies, no meta-analysis

Content correction 2026-09-27
"Anaerobic capacity for sprint distances 200-500 m", "the 200/500/1000 m distances demand a different aerobic/anaerobic balance", "stroke length falls under fatigue", "upper-body endurance is a specific trainable ability" -> not in the abstract; removed or labelled as inference
Added the abstract's findings (anthropometry, aerobic + anaerobic capacity, upper-body strength/thickness, sex pattern, kayak ≠ canoe)
