Aquatic cycling—What do we know? A scoping review on head-out aquatic cycling

et al. 2017

Over the past few years, aquatic cycling has become a trending fitness activity. However, the literature has not been reviewed exhaustively. Therefore, using scoping review methodology, the aim of this review was to explore the current state of the literature concerning aquatic cycling. This study specifically focused on study designs, populations and outcomes. A comprehensive search of seven databases (PubMed, MEDLINE, Cinahl, Embase, PEDro,Web of Science, WorldCat) was conducted up to 30th September 2016. GoogleScholar, World Cat, ResearchGate, specific aquatic therapy websites and aquatic therapy journals were searched to identify additional literature. Full-text publications in English, German or Dutch were included. Studies were included when the intervention involved head-out cycling carried out in 10° to 35° Celsius water. Exclusion criteria were the use of wet suits or confounding interventions that would affect participants’ homeostasis. 63 articles were included and the study parameters of these studies were summarized. Using three grouping themes, included studies were categorised as 1) single session tests comparing aquatic versus land cycling, or 2) aquatic cycling only sessions investigating different exercise conditions and 3) aquatic cycling intervention programmes. Although the experimental conditions differed noticeably across the studies, shared characteristics were identified. Cardiovascular parameters were investigated by many of the studies with the results suggesting that the cardiac demand of aquatic cycling seems similar to land-based cycling. Only six studies evaluated the effect of aquatic cycling interventions. Therefore, future research should investigate the effects of aquatic cycling interventions, preferably in individuals that are expected to gain health benefits from aquatic cycling. Moreover, this comprehensive outline of available literature could serve as a starting point for systematic reviews or clinical studies on the effects of aquatic cycling on the cardiovascular responses.

“…Increments were mostly achieved by an increase in pedalling frequency. Seven studies of the aforementioned studies controlled exercise intensity by electronically regulated pedalling resistance [ 10 , 21 , 24 – 27 , 31 ]. An additional six studies compared submaximal continuous aquatic cycling with land cycling [ 33 – 38 ].…”

“…3 days before the investigation, a graded peak oxygen uptake (VO 2 peak) test was carried out on an electromagnetically braked whole body ergometer (Reha-Aquabike, Swissrehamed, Chur, Switzerland) [ 9 ] . Oxygen and carbon dioxide production were measured breath-by-breath (Viasys Jäger Master Screen CPX, PanGas AG, Dagmarsellen, Switzerland) in order to calculate the respiratory exchange ratio (RER) and the anaerobic threshold.…”

Exercise in water compared to land-based exercise (LE) results in a higher release of natriuretic peptides, which are involved in the regulation of exercise-induced adipose tissue lipolysis. The present study was performed to compare the release of atrial natriuretic peptide (ANP) and free fatty acids (FFA) during prolonged aerobic water-based exercise (WE) with the release after an identical LE. 14 untrained overweight subjects performed 2 steady state workload tests on the same ergometer in water and on land. Before and after exercise, venous blood samples were collected for measuring ANP, FFA, epinephrine, norepinephrine, insulin and glucose. The respiratory exchange ratio (RER) was determined for fat oxidation.The exercises resulted in a significant increase in ANP in LE (61%) and in WE (177%), and FFA increased about 3-fold in LE and WE with no significant difference between the groups. Epinephrine increased, while insulin decreased similarly in both groups. The RER values decreased during the exercises, but there was no significant difference between LE and WE. In conclusion, the higher ANP concentrations in WE had no additional effect on lipid mobilization, FFA release and fat oxidation. Moderate-intensity exercises in water offer no benefit regarding adipose tissue lipolysis in comparison to LE.

Zusammenfassung Problemstellung: In der Sportmedizin bestehen zum Herzratenvariabilit?t (HRV) ? Schwellenkonzept keine vergleichenden experimentellen Grundlagen mit Standardtestverfahren im Wasser. Methode: Bei 12 anamnestisch gesunden und trainierten Probanden wurde w?hrend Ergometerbelastungen (Arm-/Beindrehkurbel) im Wasser und an Land spirografisch der Gasstoffwechsel gemessen. Zeitsynchron mit der Erfassung respiratorischer Parameter wurde die hochfrequente Komponente der HRV (logarhithmierte HF-Leistung, lnHF) mit einem EKG auf jeder Belastungsstufe zeitkontinuierlich aufgezeichnet. Aus dem Produkt lnHF und der Zentralherzfrequenz wurde verlaufskinetisch die Leistung (Watt) an der respiratorischen Schwelle 2 quantitativ bestimmt und mit der reliablen Messmethodik der Gasanalyse verglichen. Ergebnis: Die Differenzen der mittleren Leistungskennwerte unterscheiden sich nicht (p>0,05). Der mittlere Bias weicht nur wenig von Null ab (?0,6 Watt). Die ?bereinstimmungsgrenzen liegen zwischen ?20,1 und 18,8 Watt. Diskussion: Auf der Basis eines quantitativen Vergleichs der Leistungskennwerte stimmt das HRV-Schwellenkonzept mit dem respiratorischen Referenzverfahren auch bei Arm-/Bein-Drehkurbelarbeit im Wasser gut ?berein.
