Kemble2,3 1Central Washington University, Ellensburg, WA; 2Confluence Health, Wenatchee, WA; 3University of Washington, Seattle Washington Cancer Related Cognitive Impairment (CRCI), or “chemo-brain,” has become a recognized problem for cancer survivors; however, limited evidence exists concerning interventions that may improve cognition for this population. Symptoms include: short-term memory loss, decreased concentration, mental “fogginess” and fatigue. These symptoms may contribute to a decrease in quality of life. PURPOSE: To measure the effectiveness of a multi-dimensional cancer survivor rehabilitation program on cognition as well as physical and psycho-social functioning. METHODS: Sixty-two post-treatment cancer survivors, (7 men, 55 women, 35-77 years) were subjects in a one group, pre-post, quasi-experimental design. Subjects were cleared for exercise prior to participation by their primary oncologist. The program consisted of two, 90 minute sessions per week for 12 weeks. Each meeting was divided into 3 sections: an educational activity, cardiovascular endurance training, and a strength and flexibility session. A subset of this group (n= 22) participated in brain exercise games once per week for 15 minutes. Dependent measures included: the Montreal Cognitive Assessment (MoCA), the General Practitioner assessment of Cognition (GPCOG), aerobic capacity, body fat %, lower body flexibility, handgrip strength, quality of life, Schwartz fatigue scale, and the LASA scale (fatigue, anxiety, confusion, depression, energy and anger). RESULTS: The following measures showed statistically significant (p \u3c .05) improvements: GPCOG increased 6.6%, aerobic capacity increased 20.7%, body fat decreased by 1.9%, lower body flexibility improved 14.3%, handgrip strength increased 11.6%. Quality of life increased 10.4%. Fatigue measured by the Schwartz scale decreased 18.5%, LASA scale results: fatigue decreased 36.7%, depression decreased 49.2%, confusion decreased 42.7%, energy increased 23.8%, anger decreased 40.8%, anxiety decreased 30.7%. MoCA increased 4.3% and approached significance (p= .056). CONCLUSION: The combination of tools acquired in the cancer rehabilitation program proved effective in improving cognition and reducing symptoms often seen in post-treatment cancer survivors. The mechanism for cognitive improvement cannot be ascertained from the design of this study but may hold promise for future studies

It was held as a follow-on for a seminar 10161, of the same title, that took place in late April 2010 during the initial eruption of Eyjafjallajokull. In spite of the travel disruptions caused by the eruption of the volcano, the original seminar received a respectable turnout by European, mainly German and Italian participants. Unfortunately, the eruption hindered participation from overseas or even more distant parts of Europe. This caused the seminar to cover only part of the original objective. The follow-on seminar focused on the remaining objectives, in particular to bio-ware and constraint solving methods.

Miller Central Washington University, Ellensburg, WA Systematically regulating intensity while exercising in water is problematic given the nature of the workout medium. One approach to controlling exercise intensity is self-regulation by instructing participants to exercise over a range of prescribed rating of perceived exertions (e.g. RPE, Borg 6-20 scale). PURPOSE: This study investigated the cardiorespiratory responses to a series of incremental, perceptually self-regulated shallow water exercise (SR-SWE) efforts. It was hypothesized that (1) a steady rate cardiorespiratory response (oxygen uptake (V̇O2)& heart rate (HR)) for sustained SR-SWE efforts prescribed at RPE 9, 11, 13, 15 and 17 would be achieved, and (2) V̇O2 would be linearly, positively and strongly related to prescribed perceived exertions ranging from RPE 9 to 17. METHODS: Male volunteers (n=6, 23±1 years) participated in a familiarization session and a second testing period in which they performed five, five min SR-SWE efforts prescribed at RPE 9, 11, 13, 15, and 17. In addition, participants performed an incremental, five min SR-SWE bout to a max of RPE 20 to determine peak V̇O2 and HR. V̇O2 (Parvo-Medics TrueMax 2400, indirect calorimetry), HR (Polar, telemetry) and blood lactate (BLa) concentration (Analox Instruments) were measured for all SR-SWE efforts. Participants were immersed to axillary level (~75% of stature; water temperature, ~28-290 Celsius) for all exercise efforts. RESULTS: Peak V̇O2, HR, respiratory exchange ratio, and BLa was 3.63±0.25 l·min-1, 187±6 b·min-1, 1.08±0.03, and 11.7±1.2 mM, respectively. For RPE efforts 9, 11, 13, 15 & 17, both V̇O2 and HR for mins two through five were the same (P\u3e0.05). Steady rate V̇O2 and HR, and BLa ranged from 0.69±0.10 l·min-1, 83±5.8 b·min-1, 1.53±0.6 mM (RPE 9, “very light”) to 3.10±0.471 l·min-1, 168±7 b·min-1, and 6.4±1.5 mM (RPE 17, “very hard”), respectively (P\u3c0.05). Percent V̇O2 and %HR peak increased in a step-wise fashion from RPE 9 (19.0±2.0 and 44.3±2.7%) to RPE 17 (85.1±7.4 and 90.4±2.5%, respectively) (P\u3c0.05). V̇O2 and HR were linearly and strongly correlated with RPE (R ranged from 0.94 to 0.99, p\u3c0.05). CONCLUSION: Self-regulation of intensity based on prescribed RPE is a viable way of regulating intensity while exercising in a shallow water medium.

Fisher Central Washington University, Ellensburg, WA PURPOSE: The primary aim of this study was to examine physiological and perceived exertion responses to a high intensity, shallow water exercise interval workout (HISWE). It was hypothesized that HISWE would result in cardiometabolic (oxygen uptake (V̇O2) & heart rate (HR)) and rating of perceived exertion (RPE, Borg 6-20 scale) responses that would be classified as “vigorous” according to the American College of Sports Medicine (ACSM) intensity guidelines. METHODS: Volunteers (n=9, females, 26±6 yrs) completed the following three testing sessions (TS): TS1, familiarization; TS2, head-out, shallow water incremental exercise to exhaustion to determine peak V̇O2 (indirect calorimetry) and HR (telemetry); and, TS3, performed HISWE while being monitored for V̇O2, HR, and blood lactate responses. HISWE consisted of a warmup followed by 4 x 4 minute (min) bouts. Each bout consisted of 20 seconds (s) exercise followed by 10 s of rest (8 x 20 s exercise effort per 4 min bout) with a 1-min rest between bouts. Participants were instructed to perform each 20 s effort all-out. Exercise bouts were performed with participants immersed in water (~28-290 celcius) to axillary level. RESULTS: Peak V̇O2 and HR, 2.7±0.3 l.min-1 and 181±8 bpm, respectively. Overall, V̇O2, HR, and RPE for HISWE was 2.0±0.2 l.min-1 (73±5% V̇O2 peak), 156±8 bpm (86±2% HR peak), and 18.5±1.1 (~extremely hard), respectively. Percent V̇O2 and %HR peak increased in a step-wise fashion from bout 1 (71±6 and 84±4%) to bout 4 (85±6 and 94±2%, respectively) (P\u3c0.05). Despite participants being asked a-priori to perform each 20 s exercise interval all-out, there was a gain in physiological strain (end-spurt) during the final 4 min bout (greater %V̇O2, %HR, and blood lactate for bout 4 versus 1, 2, & 3; P\u3c0.05). Peak blood lactate was 9.2±1.7 mM following the last 4 min HISWE bout. CONCLUSION: Cardiometabolic and RPE responses indicated a vigorous to near-maximal effort according to ACSM’s guidelines for exercise intensity. The presence of a cardiometabolic end-spurt noted in bout 4 suggests that participants, overall, did not fully tax their physiological reserve during the shallow water interval workout, possibly to avoid overextending themselves in order to prevent premature fatigue.

Antioxidants such as cocoa flavanols have been used as a supplement to prevent oxidative stress; however, the benefits of dietary antioxidants for athletic performance after muscle soreness (MS) is unclear. The purpose of this study was to examine the effects of cocoa flavanols after a MS inducing protocol. METHODS In a randomized, double-blinded design, 13 male collegiate rugby players consumed either chocolate milk (CHOC) or chocolate milk with additional cocoa flavanols (CocoaCHOC) during a 7-d loading phase. MS was induced by a drop jump protocol on day 5 of the intervention. Athlete performance was assessed with vertical-jump and yo-yo tests and subjective measures of soreness 5 d before and 2 d post-MS protocol. Urinary markers of oxidative stress (isoprostanes) were assessed before and 48 h post-MS. RESULTS No changes were observed between the groups over time for isometric torque (P = .63), vertical jump performance (P = .39), and yo-yo testing (P = .57) between the trials. No interaction was found in isoprostanes levels between the trials (CocoaCHOC baseline: 88 ± 0.38 pg/mL and 48 h post-MS: 81 ± 0.53 pg/mL; P = .82; and CHOC baseline: 98 ± 0.96 pg/mL and 48 h post-MS: 96 ± 0.38 pg/mL; P = .59). No main effect (treatment × time; P = .58) was observed for isoprostanes. Although not significant, the CocoaCHOC group ran 97 meters further than the CHOC group in the yo-yo test. CONCLUSIONS Cocoa flavanols added to a post-exercise recovery beverage for 7 d has no oxidative stress or athletic performance benefits.

Temporal dependency of sway during single leg stance changes with age
Clinical biomechanics (Bristol, Avon), 2015
Balance deteriorates with age and fall related injuries are often linked to long-term disability ... more Balance deteriorates with age and fall related injuries are often linked to long-term disability and loss of independence in older adults. This study focuses on the task of establishing single leg stance, which requires the ability to shift the center of mass onto the supporting leg. Fifteen younger adults and eight older adults participated in the study. Subjects performed a step with self-selected step length onto the force plate to establish a single leg stance (SLS) on their dominant leg. The first four seconds of SLS were analyzed to investigate age related temporal dependencies of sway area, sway velocity, anterior-posterior sway, and medio-lateral sway. Younger adults show a rapid decrease of sway area, anterior-posterior sway, medio-lateral sway, and sway velocity within the first four seconds while older adults show elevated initial values in anterior-posterior sway and sway velocity and less decrease over time. Older adults have not only diminished initial sway, but also l...
