“…None of the subjects were considered trained or elite athletes. Brown et al (1997) used a similar protocol while a subject performed supported DWR. The same protocol was used in the current investigation to allow a statistical comparison.…”

“…In these studies, a subject performed a prolonged exercise test at a single intensity. The protocol employed by Brown et al (1997) and replicated in the present study was designed to produce a graded response. An interesting and unexpected result of the current investigation was that DWR performed without the aid of a flotation device using a protocol previously developed (Brown et al, 1997) could not be performed…”

“…All subjects performed a peak oxygen consumption (VO2 pe ak) test in the water using a graded protocol developed for DWR (Brown et al, 1997). A subject began the test in the water at a cadence (leg frequency) of 72 strides-min" 1 .…”

“…Regression equations predicting oxygen consumption (VO 2 ) from heart rate have been developed for many modes of exercise (Londeree and Ames, 1976;Londeree et al, 1995), including deep water running (DWR) (Brown et al, 1997). Deep water running is a form of aquatic exercise that attempts to simulate land running (Ritchie and Hopkins, 1991) and may be performed by a subject supported with a flotation device (wet vest) or without support.…”

“…Expressing both of these variables as percentages of maximum has been shown to produce the best regression equation for comparison of a variety of different exercise modes (Londeree et al, 1995;Brown et al, 1997). However, when this procedure was attempted in the current investigation, the Pearson correlation coefficient produced, using the male data, was artificially inflated (0.92), since the majority of the data points were matches of 100% vs 100%.…”

1998) Regression of oxygen consumption on heart rate during supported and unsupported deep water running in healthy mixed gender subjects, Sports Medicine, Training and Rehabilitation, 8:3,[291][292][293][294][295][296][297][298][299] The purpose of this study was to investigate the relationship between heart rate and oxygen consumption (VO 2 ) during the performance of unsupported and supported deep water running (DWR) in young healthy males and females. A second purpose was to compare regression of predicted VO 2 on heart rate between the two methods of support (i.e., unsupported vs vest supported). Thirty-three college-aged students (18 males and 15 females), aged 19 to 28 years, volunteered for this study. Each subject completed practice sessions until satisfactory DWR performance was attained. Subjects returned for a VO 2p eak test in the water on a subsequent day. The test involved the performance of a DWR graded exercise test at a metronome cadence of 72 strides-min -1 with a cadence increase of 12 strides min" 1 in each subsequent 3 minute stage. Heart rate and VO 2 were monitored continuously throughout the test. Statistical analysis of the difference in physiological stimulus between supported and unsupported DWR in female and male subjects was made using simple linear regression. F-ratios were developed from the residual sum of squares of a restricted and unrestricted model to test the proposed hypotheses. It was shown that unsupported DWR is a mode of exercise that does not produce a graded physiological response. This study demonstrated that during unsupported DWR heart rate predicts VO 2 in ml-min -1 -kg -1 with the highest correlation coefficient and the lowest standard error in both gender groups. All developed regression equations were statistically different between gender and between the two methods of support.

The aquatic environment offers cardiorespiratory training and testing options particularly for individuals unable to adequately train or test on land because of weight bearing, pain or disability concerns. No systematic review exists describing cardiorespiratory fitness protocols used in an aquatic environment. This review investigated the different head-out water-based protocols used to assess cardiorespiratory fitness. Our comprehensive, systematic review included 41 studies with each included paper methodological quality assessed using the statistical review of general papers checklist. Diverse protocols arose with three major categories identified: conducted in shallow water, deep water, and using special equipment. Thirty-seven articles presented data for peak/maximal oxygen consumption (VO2peak/VO2max). Twenty-eight of 37 studies predefined criteria for reaching a valid VO2peak/VO2max with shallow water exercise demonstrating 20.6 to 57.2 mL/kg/min; deep water running 20.32 to 48.4 mL/kg/min; and underwater treadmill and cycling 28.64 to 62.2 mL/kg/min. No single, accepted head-out water-based protocol for evaluating cardiorespiratory fitness arose. For clinical use three cardiorespiratory fitness testing concepts ensued: water temperature of 28–30 °C with difference of maximum 1 °C between testing participants and/or testing sessions; water depth adapted for participant aquatic experiences and abilities; and intensity increment of 10–15 metronome beats per minute.
