Book Physiological Differences Between Land and Water Treadmill Running

Download or read book Physiological Differences Between Land and Water Treadmill Running written by Rachel Kemp Rife and published by . This book was released on 2008 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: To determine if water treadmill running with (WTR-S) or without water shoes (WTR-NS) could produce similar cardiorespiratory responses as land treadmill running (LTR). Design and Setting: A repeated measures design was used to assess the differences between LTR and WTR-S and WTR-NS. All testing was done in either a research laboratory or an athletic training hydro-therapy room. Subjects: Eighteen trained runners (9 men and 9 women) volunteered for this study. All 18 subjects participated in three running conditions. Measurements: Treadmill speed, HR, and SF were assessed at four exercise intensities representing 50%, 60%, 70%, and 80% of land VO2max for all three running conditions. Results: WTR with and without water shoes produces similar cardiorespiratory responses to LTR. The VO2/HR relationship showed that at a HR of 150 bpm, VO2 was significantly less (p

Book A Biomechanical and Physiological Comparison of Deep water Running Styles

Download or read book A Biomechanical and Physiological Comparison of Deep water Running Styles written by Garry L. Killgore and published by . This book was released on 2003 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: The purpose of this investigation was to identify a deep-water running (DWR) style that most closely approximates terrestrial running. Methods: Twenty healthy male and female intercollegiate (NCAA III) distance runners were videotaped from the right sagittal view while running on a treadmill (TR) and in deep water at 55-60% of their TR VO2[subscript max] using each of four DWR styles: shod cross-country (SCC), barefoot cross-country (BCC), shod high-knee (SHK), and barefoot high-knee (BHK). All biomechanical data were digitized and analyzed using the Peak Motus® system. Physiological variables of interest were oxygen consumption (V02), heart rate (HR), and rating of perceived exertion (RPE). Biomechanical variables of interest were horizontal (X) and vertical (Y) displacement of the knee and ankle, and stride rate (SR). An ANOVA with repeated measures was utilized to ascertain the differences across styles. The alpha significance level was set at .05, and a post hoc pairwise analysis was conducted with a Bonferonni adjustment of the alpha level. Results: Omnibus significant differences were found for all physiological variables: VO2 (p

Book Physiological Responses at the Rating of Perceived Exertion at and Above the Gas Exchange Threshold During Treadmill Running

Download or read book Physiological Responses at the Rating of Perceived Exertion at and Above the Gas Exchange Threshold During Treadmill Running written by Kristen C. Cochrane and published by . This book was released on 2016 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purposes of this study were to examine: 1) the metabolic, cardiovascular, respiratory, neuromuscular, and velocity responses during continuous, constant rating of .perceived exertion (RPE) runs at the RPE corresponding to the velocity at the gas exchange threshold (RPEGET) and 15% above GET (RPE GET+15%); and 2) the metabolic efficiency changes during continuous, constant RPE runs at RPEGET and RPEGET+15%. Eleven moderately trained runners performed an incremental treadmill test to exhaustion. GET and GET+15% were determined from the incremental test to exhaustion, and the velocity at GET and GET+15% were used to estimate the RPEGET and RPEGET+15% using linear regression. On separate days, subjects performed 60 min runs at RPEGET and RPEGET+15%, and physiological, neuromuscular, and perceptual responses were recorded. Polynomial regression analyses were used to examine the patterns of responses for all of the variables and paired-samples t-tests were used to determine changes in metabolic efficiency at RPEGET and RPEGET+15%. The results of the polynomial regression analyses indicated that there were negative, quadratic relationships (R2 = 0.96 -- 0.99) for V˙ O2, RER, V˙ E, and velocity vs. time at RPEGET and RPEGET+15%; positive, quadratic relationships (R2 = 0.87 and 0.74) for Fb vs. time at RPEGET and RPEGET+15%; and positive, linear (r2 = 0.73), and no significant (r2 = 0.0) relationships for HR vs. time at RPEGET and RPEGET+15%, respectively. There were negative, linear relationships (r2 = 0.96 and 0.63) for VL and VM EMG RMS vs. time, and positive, linear relationships (r 2 = 0.72 and 0.40) for VL and VM EMG MPF vs. time at RPEGET. In addition, there was a negative, linear relationship (r2 = 0.16) for VL EMG RMS vs. time, a positive, quadratic relationship (R2 = 0.74) for VM EMG RMS vs. time, and positive, quadratic relationships (R 2 = 0.73 and 0.96) for VL and VM EMG MPF vs. time at RPEGET+15% . There were decreases in metabolic efficiency at RPEGET and RPEGET+15%. These findings indicated that the only variable that tracked RPE was the normalized, composite HR vs. time response at RPE GET+15%, and that treadmill running at RPEGET and RPE GET+15% was sustainable for up to 60 min.

Book Selected Physiologic Responses in Deep Water Running with Endurance Athletes

Download or read book Selected Physiologic Responses in Deep Water Running with Endurance Athletes written by Erik W. Anderson and published by . This book was released on 2003 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The goal of this study was to determine which physiologic response, heart rate (HR) or the rating of perceived exertion (RPE) was a better indicator of oxygen consumption (V02) during a maximal stress test using deep water running. Nine men and four women from the Spokane, Washington running community and the Community Colleges of Spokane 1998 cross country team performed a graded exercise test to achieve V02peak. The graded exercise test used a metronome and a series of 2-minute stages using designated leg cadences to increase work intensity, until a marker for V02peak was met, the subjects were too exhausted to continue or they showed repeated improper mechanics. Data analysis consisted of a multiple linear regression comparing V02, HR and RPE at all levels of intensity. V02 was designated as the dependent variable and HR and RPE were the independent variables. The results of the data analysis showed extremely high correlations between all three variables at all intensity levels. A prediction equation for V02 during deep water running using endurance athletes was determined. The potential ramifications of this study may be the concept that land and water exercise are so different that they should not be compared when attempting to designate workload. The findings also indicate the possibility that regardless of mode, HR and RPE remain correlated as well as both being correlated to V02 and further research is necessary using other populations to determine whether the conditions hold true for others"--Document.

Book excerpt: Aquatic treadmill running has become increasingly popular for rehabilitation and training purposes due to decreased joint impact on the lower extremities, which is beneficial for special populations such as the injured, elderly, arthritic, and obese (Greene et al., 2009; Hall, Grant, Blake, Taylor, & Garbutt, 2004). Accordingly, researchers have compared key differences such as heart rate (HR), oxygen consumption (VO2), respiratory exchange ratio (RER), stride frequency, and rating of perceived exertion (RPE) between land and water running at maximal and submaximal efforts (Brubaker, Ozemek, Gonzalez, Wiley, & Collins, 2011; Rife, Myrer, Feland, Hunter, & Fellingham, 2010; Rutledge, Silvers, Browder, & Dolny, 2007; Silvers, Rutledge, & Dolny, 2007). As the benefits of aquatic treadmill running continue to be unveiled, there is an interest for healthy individuals to use the system to supplement training while limiting joint stress. Rutledge et al. (2007) revealed VO2 values at 6.5, 7.5 and 8.5 mph on an aquatic treadmill with no jet resistance to be 33.97 ℗ł 4.0, 37.96 ℗ł 4.0, and 43.6 ℗ł 4.0 mL0́Økg-10́Ømin-1, respectively. Watson et al. (2012) also revealed VO2 values on an aquatic treadmill at 4.5, 6.0, and 7.5 mph with no jet resistance to be 20.58 ℗ł 3.36, 29.27 ℗ł 3.89, and 35.77 ℗ł 4.02 mL0́Økg-10́Ømin-1, respectively. These articles demonstrate the linear relationship that exists with increasing workloads with concomitant increases in VO2 with aquatic treadmill running. As metabolic demands increase, a reliance on anaerobic metabolism ensues and the work rate at which lactate begins to accumulate in the blood is called the lactate threshold (LT) (Stainsby & Brooks, 1990). The importance of determining LT is supported by a large body of evidence to predict aerobic endurance capacity (Faude, Kindermann, & Meyer, 2009). As such, researchers have employed great efforts to predict LT via field tests to determine the correct training intensity for endurance athletes (McGehee, Tanner, & Houmard, 2005).An early study of LT revealed a strong relationship (r 9́Æ .91) between treadmill velocity at the onset of plasma lactate accumulation and running performance at distances ranging from 3.2 km to 42 km (Farrell, Wilmore, Coyle, Billing, and Costill, 1979). In other words, a faster sustainable work rate prior to a lactate accumulation or threshold will increase performance. Comparisons for lactate concentrations during deep water and land treadmill running have been examined previously. Frangolias and Rhodes (1996) reviewed that during submaximal intensities of deep water versus land running, at the same relative VO2 water exercise resulted in a lower HR with higher blood lactate, RER, and RPE. These same authors previously reported that at maximal efforts on land versus deep water running, there was no statistical difference between lactate concentrations 30 s and 5 min post-exercise (Frangolias & Rhodes, 1995). However, not all water immersion running studies support similar peak lactate values (Frangolias & Rhodes, 1996; Svedenhag & Seger, 1992).In a shallow water pool, a study by Town and Bradley (1991) revealed no statistical differences between land and water running for peak lactate values. However, lactate concentration in the water was 80% of that from land exercise. The authors stated that the 0́−push-off0́+ phase, which enabled ground contact, elicited similar running technique to land treadmills and could be partially responsible for similar physiological responses to land.In recent years the availability of aquatic treadmills allows for a more favorable comparison of land and water running due to the implication of the 0́−push-off0́+ phase as discussed by Town and Bradley. Silvers et al. (2007) revealed no statistical difference between peak lactate concentrations in VO2peak tests run on land versus aquatic treadmills. Zobell (2009) examined a comparison of LT between land and aquatic treadmill running which showed higher lactate levels in the water compared to land. However, no clear answers have developed as to a comparison of the LT on land vs. aquatic treadmill running. Therefore, the purpose of this study was to determine the LT while running on a land and an aquatic treadmill and compare to see if the intensities are equivalent.

Book The Effects of Aquatic Exercise on Physiological and Biomechanical Responses

Download or read book The Effects of Aquatic Exercise on Physiological and Biomechanical Responses written by William M. Denning and published by . This book was released on 2010 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to recent advances in aquatic research, technology, and facilities, many modes of aquatic therapy now exist. These aquatic modes assist individuals (e.g., osteoarthritis patients) in the performance of activities that may be too difficult to complete on land. However, the biomechanical requirements of each aquatic therapy mode may elicit different physiological and functional responses. Therefore, the purpose of this thesis was to: (a) provide a review of the physiological and biomechanical differences between aquatic and land based exercises, and (b) examine the acute effects of underwater and land treadmill exercise on oxygen consumption (VO2), rating of perceived exertion (RPE), perceived pain, mobility, and gait kinematics for patients with osteoarthritis (OA). Methods consisted of the retrieval of experimental studies examining the physiological and biomechanical effects of deep water running (DWR), shallow water running (SWR), water calisthenics, and underwater treadmill therapy. The methods also examined the physiological and biomechanical effects on 19 participants during and after three consecutive exercise sessions on an underwater treadmill and on a land-based treadmill. Based on the studies reviewed, when compared to a similar land-based mode, VO2 values are lower during both DWR and SWR, but can be higher during water calisthenics and underwater treadmill exercise. RPE responses during DWR are similar during max effort, and stride frequency and stride length are both lower in all four aquatic modes than on land. Pain levels are no different between most water calisthenics, and most studies reported improvements in mobility after aquatic therapy, but no difference between the aquatic and land-based modes. The OA participants achieved VO2 values that were not different between conditions during moderate intensities, but were 37% greater during low intensity exercise on land than in water (p = 0.001). Perceived pain and Time Up & Go scores were 140% and 240% greater, respectively, for land than underwater treadmill exercise (p = 0.01). Patients diagnosed with OA may walk on an underwater treadmill at a moderate intensity with less pain and equivalent energy expenditures compared to walking on a land-based treadmill.

Book The Effect of Auditory motor Synchronization on Physiological Responses and Perceived Exertion During Treadmill Running Music

Download or read book The Effect of Auditory motor Synchronization on Physiological Responses and Perceived Exertion During Treadmill Running Music written by Tracy J. Kiel and published by . This book was released on 2007 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synchronous, asynchronous, and no music were compared to determine the effect of synchronization of musical tempo and running cadence on physiological and perceptual responses to exercise. Eight subjects, three males and five females, participated in one assessment trial and three experimental trials. During the assessment trial, subjects performed a VO2max test, and researchers then calculated running cadence at a velocity approximating 70 percent of VO2max. During the three experimental trials, subjects ran for 20 minutes at approximately 70 percent of VO2max on a motorized treadmill with synchronous, asynchronous, and no music, where the order of trials was randomly assigned to each participant. VO2, blood lactate, heart rate, perceived exertion, and cadence were recorded every five minutes. A two-way ANOVA revealed a significant main effect for time on RPE, HR, VO2, and blood lactate. The effect of music condition was not significant, p>.05. Results and recommendations for further studies are discussed.
