The purpose of this study was to investigate whether 3 days of dietary nitrate supplementation has positive effects on exercise performance and energy metabolism at rest and during strenuous knee exercise, and exercise recovery. The experimental protocol was a double blind, placebo-controlled, two-period, and within-subjects design. Fourteen healthy nonsmoking males (22.71 ± 0.72yr, 72.93 ± 2.35kg, and 47.67 ± 1.56 ml/kg/min VO2max) participated in the study. Two supplements (nitrate lozenge; NO-L or placebo; PLA) were orally administrated randomly at 48 and 24 hours before each trial day and again 40 minutes before each exercise trial. Total work, peak torque, and respiratory gases were automatically collected during repeated knee extensions/flexions (isokinetic concentric contractions with dominant leg; 4 sets of 28 repetitions at 180°/sec with 30 sec rest intervals) and recovery (6 contractions of 1 repetition maximum with 120 vii sec between contractions). For these results, peak torque, rate of fatigue, work efficiency, and rate of recovery were calculated. Blood specimens were collected at rest before and after the treatment, post exercise, and end of recovery to track the changes in blood glucose and lactate concentrations. There was a significant inverse correlation for total work during knee extension exercise and oxygen consumption (PLA: r = -.560 and NO-L: r = -.546; p < .01, respectively). During the exercise, RER was significantly higher for PLA compared with NO-L (PLA: 1.42 ± 0.02 vs. NO-L: 1.38 ± 0.02: p = .03). Work within each set and total work performed were higher for NO-L, but these differences were not significant. However, NO-L enhanced exercise efficiency by 3.3% when compared with PLA (PLA: 2497.5 ± 134.56 ft-lb/L/min vs. NO-L: 2578.7 ± 132.24 ftlb/L/min; p = .05). Extensor peak torque recovery rate slope was not significant, but meaningfully faster for NO-L (PLA: 2.39 ± 0.52% vs. NO-L: 3.06 ± 0.54%; p = .09) and significant interaction effect (p = .02) was found during recovery contractions, especially from contractions 2 to 3 (p = .03). It is also worth noting that differences in time to peak torque during knee extension exercise for NO-L and PLA approached significances (PLA: 0.213 ± 0.01 sec vs. NO-L: 0.200 ± 0.01 sec; p = .08). The results suggest that 3 days of dietary nitrate supplementation improves rate of exercise recovery and enhances work efficiency during vigorous resistance exercise. / text

Ectotherms regulate body temperature (Tb) primarily through behavioral interactions with their environment. These animals also have limited aerobic scopes and must rely on anaerobic metabolism to support intense activity; lactate byproduct and glycogen depletion are two consequences of anaerobic metabolism that must be dealt with during exercise recovery. It has been suggested that, in many ectothermic species, Tb may affect the rate of lactate clearance and glycogen repletion during recovery from intense exercise. This study investigated thermoregulatory behavior in Western Fence Lizards (Sceloporus occidentalis) to determine preferred Tb during exercise recovery. I hypothesized that animals would select higher Tb’sduring the recovery period on the basis that biochemical processes occur at faster rates at high temperatures, which may facilitate a more rapid reduction of lactate and replenishment of glycogen stores. However, it was found that control animals maintained a constant Tb of 33°C, while exercised animals cooled Tb to 30°C 20 minutes after exercising, and eventually warmed to 32°C by the 2 hour mark. Animals were found to be able to cool Tb by a maximum of 0.175°C/min given the available temperatures, which negated possible effects of temperature variation on Tb during exercise trials and transport. My results suggest a benefit of lowered Tb to facilitate exercise recovery in these animals. Behavioral hypothermia in S. occidentalis may be caused by physiological triggers associated with intense activity such as hypoxia, hypercapnia, or elevated blood lactate concentration. However, these speculations must be confirmed by further research.

Victims of exertional heat stroke (EHS) in whom treatment is delayed have higher rates of multi-organ failure and a greater number of fatalities. Death related to EHS is preventable, through immediate treatment via cold-water immersion (CWI). To date little is known about the influence of treatment delays on core cooling following EHS. Thus we sought to examine the effects of treatment delays on cardiovascular and thermal responses prior to, during, and following CWI treatment in individuals with exercise-induced hyperthermia. Our findings demonstrate that treatment delays resulted in a sustained level of hyperthermia and cardiovascular strain that significantly increased the time an individual is at risk to the potential lethal effects of EHS. Moreover, we report that cold water immersion treatment is powerful enough to overcome the adverse effects of treatment delays and rapidly reduce core temperatures while facilitating the re-establishment of blood pressure towards normal resting levels.

No. of bitstreams: 0 Previous issue date: 2011-03-31 / Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) / Introdução: Os pacientes com Miopatia Mitocondrial (MM) e Oftalmoplegia Externa Progressiva (OEP) apresentam disfunção na cadeia respiratória com incapacidade de aumentar a extração de oxigênio muscular e sintetizar ATP aerobicamente, levando à intolerância ao esforço e lentificação da cinética do O2. Quando a extração de oxigênio é comprometida, na tentativa de se manter o consumo de oxigênio muscular, uma hipótese é que estes pacientes poderiam aumentar compensatoriamente a oferta de oxigênio, apresentando, assim, uma resposta hipercinética cardiovascular e ventilatória. Por outro lado, alguns indícios de menor oferta de oxigênio foram encontrados em pacientes com MM, como um menor fluxo sanguíneo muscular no antebraço e uma maior capacidade de produção de ATP após a suplementação de oxigênio. A cinética do O2 na fase de recuperação (REC) nos fornece, assim, subsídios quanto ao pagamento do débito de oxigênio tecidual e ao reabastecimento do estoque de oxigênio sanguíneo após o exercício. Ao nosso conhecimento, a cinética do O2 REC nunca foi avaliada nos pacientes com MM, assim como a integração desta variável com as respostas não-invasivas cardiovasculares e de extração de oxigênio muscular. Objetivo: contrastar as dinâmicas da oferta e da utilização de oxigênio na recuperação do exercício em pacientes com MM; e identificar os principais mecanismos fisiopatológicos da intolerância ao esforço nestes indivíduos. Métodos: Foram avaliadas em 12 pacientes com MM e 12 controles saudáveis, as cinéticas de recuperação: (i) do O2 pulmonar, (ii) da variação na concentração da deoxiemoglobina ([HHb], mensurada pela espectroscopia de raios quasi infravermelhos - NIRS) no vasto lateral, (iii) do débito cardíaco (DC) por bioimpedância transtorácica, após um teste de carga constante de alta intensidade (70% da carga máxima atingida em teste incremental prévio) até o limite da tolerância em cicloergômetro. Resultados: Foram observadas cinéticas mais lentas de reoxigenação da [HHb], ([HHb] = 43,7 ± 21,2 vs 27,5 ± 6,7) e do O2 ( O2 = 58,1 ± 25,1 vs 38,8 ± 7,6) nos pacientes com MM em relação aos controles, respectivamente. Estas respostas foram associadas a uma cinética de DC mais rápida em relação ao O2, nos pacientes comparados aos controles (T½DC * 1,44 / O2 = 1,3 ± 0,4 vs 1,7 ± 0,6). Conclusão: Os pacientes com MM na forma OEP apresentam, na recuperação do exercício de alta intensidade, um pagamento elevado do débito de oxigênio contraído no exercício e reoxigenação mais lenta da [HHb]. Estas respostas, associadas à cinética mais rápida do DC em relação ao O2 são indícios de que possa haver um déficit no transporte de oxigênio microvascular, além do comprometimento mitocondrial característico desta doença. / Background: Mitochondrial Myopathy patients (MM) and Progressive External Ophthalmoplegia (PEO) present with respiratory chain dysfunction and inability to increase muscle oxygen extraction and aerobic ATP synthesis, leading to exercise intolerance and slower O2 kinetics. When oxygen extraction is impaired, in an attempt to maintain muscle oxygen uptake, these patients could increase oxygen delivery, thus exhibiting a hyperkinetic cardiovascular and ventilatory response. On the other hand, some evidence of oxygen delivery impairment was found in MM patients, such as a decrease in muscle blood flow in the forearm and a greater capacity for ATP production after oxygen supplementation. Recovery O2 kinetics provides information on tissue oxygen debt repayment and oxygen blood store replenishment after exercise. To our knowledge, recovery O2 kinetics has never been evaluated in MM patients, as well as its integration with the non-invasive cardiovascular and muscle reoxygenation responses. Objective: to contrast oxygen delivery and utilization dynamics on exercise recovery of MM patients and to identify the main pathophysiologic mechanisms of exercise intolerance in these subjects. Methods: Were evaluated in 12 MM patients and 12 healthy controls, the recovery kinetics of: (i) O2 (ii) deoxyhemoglobin variation ([HHb], measured by near-infrared spectroscopy - NIRS) in vastus lateralis, (iii) cardiac output (CO) by transthoracic bioimpedance, after a high-intensity constant work rate test (70% of maximal workload in a previous incremental test) to the limit of tolerance in a cycle ergometer. Results: We detected slower kinetics for [HHb] ([HHb] = 43.7 ± 21.2 vs. 27.5 ± 6.7) and for O2 ( O2 = 58.1 ± 25.1 vs. 38.8 ± 7.6) in MM patients compared to controls, respectively. Additionally, these responses were associated with a faster recovery CO kinetics in relation to O2 kinetics in MM patients compared to controls (T½DC*1,44 / O2 = 1,3 ± 0,4 vs. 1,7 ± 0,6). Conclusion: Patients with MM and PEO present with a higher oxygen debt and slower reoxygenation kinetics in the recovery of a high-intensity exercise test. Those responses were associated with a faster CO recovery in relation to O2 kinetics, indicating a microvascular oxygen transport deficit, besides the characteristic mitochondrial impairment observed in these patients. / TEDE / BV UNIFESP: Teses e dissertações

DEVELOPMENT AND VALIDATION OF A LIGHT WEIGHT, ENERGY DENSE, READY TO EAT (RTE) BAR Jacob Wilhelm-Maria Heick Providing additional calories in the form of an RTE bar to endurance athletes will increase performance and muscle re-synthesis, reduce muscle breakdown, and shorten recovery time. An RTE bar containing a blend of dairy proteins and carbohydrates will create a product with superior functionality, including bioactive and immunity enhancing properties from dairy derived ingredients. The protein will provide benefits in the form of easily digestible calories, essential amino acids and physical satiate. A formulation was developed and optimized, resulting in a final product that meets the required nutritional profile: 400kcal, 25grams protein per 100 gram serving size. The desired physical characteristics were achieved through processing by both conventional baking and freeze drying. The latter method improves the stability and functionality of the RTE bar. In order to meet the protein requirements of the RTE bar without compromising sensory properties, a unique protein source was developed. Using high concentrations of conventional protein sources like Whey Protein Concentrate (WPC) resulted in stale off-flavors and unappealing textures. Milk Protein Precipitate (MPP) was developed for this formulation. MPP is a curd-like ingredient created through the combined heat and acid precipitation of dairy proteins. MPP can be used effectively in high concentrations provides a subtle dairy flavor. MPP delivers a balance of casein and whey, similar to that found in milk. The effectiveness of the RTE bar formulation as a post exercise recovery food was evaluated in a human studies experiment conducted on the Cal Poly campus. The human subjects study utilized 34 Cal Poly students in a single-blind cross-over design experiment. The study compared the effects of this high protein RTE bar against a calorically equal carbohydrate bar. The bars were administered after subjects completed the pre-assigned hikes on three consecutive days. Following the cross-over design, subjects received the alternate bar in the second period of the experiment. Several blood markers involved in metabolism and inflammation were measured before and after the two treatment periods. No blood marker showed a statistically significant difference between bars, but several trends were observed. Body weight and fat percent were also unaffected by bar composition.

Thesis (MSpor)--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: Various types of post-exercise recovery strategies have become part of the modern athlete’s daily routine. It is a well known that inadequate recovery will prolong the time it takes for the runner’s body to adequately adapt between training sessions and competitions. Anecdotal claims have been made about compression garments as a beneficial method to assist recovery after training sessions and competitions. Until now limited scientific research has addressed the influence that compression garments have on the recovery process after sporting activities. The benefits of compression garments, as a possible recovery modality, are that it is costeffective, practical and easily obtainable. This study endeavored to investigate the possible influence that compression garments may have on middle-aged long distance runners’ recovery rate after a prolonged run. This is the first study that has focused on compression garments as a post-exercise recovery modality for experienced middle-aged long distance runners. The other unique aspect of this study is the prolonged two-hour treadmill protocol that was used to induce muscle soreness. In addressing the aims, a randomized, crossover study design was used to investigate the possible benefits that the high pressure (CCL II 23-32 mmHg (mercury millimeter)) graduated compression garments may bring about. Seven competitive male long distance runners (height: 176.0 ± 8.6 cm; body mass: 92.5 ± 11.8 kg; VO2max: 45.7 ± 5.0 mL.kg-1.min-1) between the ages of 36 to 51 years volunteered for the study. The runners had to complete a two-hour treadmill run at 70 % of their predetermined maximum aerobic capacity, followed by a monitored 72-hour recovery period. The first part of the prolonged run was a 90–minute variant gradient run, followed by a 30-minute downhill run. Each subject acted as his own control and visited the Stellenbosch University’s Sport Physiology Laboratory (South Africa) on two occasions, separated by 7 to 28 days. One test was done with a compression garment (23 to 32 mmHg) and the other without. Testing included the measurement of lower limb circumferences (ankle, calf, mid- and proximal thigh), plasma lactate, lactate dehydrogenase and creatine kinase concentrations and the completion of subjective questionnaires on perceived muscle soreness (visual analog scale (VAS)). The lower extremities’ functional ability was determined with a time to exhaustion (TTE) step test, a vertical jump test (VJ) and modified sit-and-reach flexibility test. Preexercise measurements were taken and immediately after and during the 72 hour after the treadmill run and repeated for the second bout. The main outcomes of this study showed that the two-hour treadmill run induced delayed onset of muscle soreness, with and without the compression garment. Evidence of this was a significant rise in plasma creatine kinase (CKp) over the duration of both trials (P < 0.05). The compression garment significantly reduced swelling in the calf muscle (41.0 ± 0.2 vs. 41.5 ± 0.5 mm; P < 0.002). Runners showed a lower perceived muscular pain and discomfort while performing functional knee movements at 24 and 48-hours after the two-hour run with the compression garment (1.2 ± 1.6 vs. 3.8 ± 2.4 cm and 0.9 ± 1.8 vs. 3.0 ± 2.6 cm on VAS, respectively; P < 0.05). Significant differences in perceived muscle soreness between the WCG and WOCG trials were observed at 24-hours after the run during rest (0.1 ± 0.2 vs. 0.4 ± 0.8 cm; P = 0.02) and with stretching (1.9 ± 1.2 vs. 3.5 ± 2.5 cm on VAS P = 0.02). The perceived pain associated with pressure was significantly lower with the compression garment at 24 (307 %) and 48-hours (237 %) after the run (P < 0.05). Blood lactate levels were reduced during the acute phase of recovery at 10 (1.8 ± 0.5 vs. 2.2 ± 0.9 mmol.L-1; P = 0.05) and 30 minutes (1.8 ± 0.5 vs. 2.4 ± 0.4 mmol.L-1; P = 0.01) after the run, as well as plasma creatine kinase concentrations were statistically significantly lower at 24-hours (238.3 ± 81.3 vs. 413.3 ± 250.8 units.L-1; P = 0.005) after exercise with the compression garment. The two-hour treadmill run and the compression garment had no significant influence on the runners’ lower limb strength, power, endurance or flexibility (P > 0.05). Compression garments demonstrated the potential to enhance recovery after prolonged strenuous exercise in well trained middle-aged runners. In addition, runners did not experience additional fatigue from the moderate to high pressure garments. The effect of higher pressure compression garments on athletic performance and the psychological influence of the garment need further investigation. / AFRIKAANSE OPSOMMING: Verskillende tipes naoefening herstelstrategië, vorm deel van die moderne atleet se daaglikse routine. Dit is wel bekend dat onvoldoende herstel sal beteken dat die atleet se liggaam langer sal neen om aan te pas tussen inoefen sessies en kompetisies. Sekere bewerings word al gemaak omtrent die voordeligheid van kompressiesokkies tydens die herstelperiode na oefening sessies en kompetisies. Tot nou toe was daar beperkte wetenskaplike navorsing oor die invloed van kompressie sokkies of die herstel proses van sport aktiwiteite. Die voordeel van kompressie sokkies as ‘n moontlike herstelmetode, is dat dit koste-effektief, prakties en maklik verkrybaar is. Hierdie studie poog om ‘n ondersoek in te stel na die moontlike invloed wat kompressie sokkies op middeljarige lang-aftstandatlete se herstelperiode sal hê na ‘n verlengde hardloopsessie. Hierdie is die eerste studie wat konsentreer op kompressie sokkies as ‘n naoefenings hersteltegniek vir ervare middeljarige lang-afstandatlete. Die ander unieke aspek van die ondersoek is die langdurige tweeuur trapmeul protokol wat gebruik word om spierpyn te veroorsaak. Om die doel te bereik, is ’n lukrake oorkruis studie gebruik om ondersoek in te stel na die moontlike voordele van die hoë druk (CCL II 23-32 mmHg) kompressie sokkies. Hierdie sokkies toon ’n progressiewe verhooging van druk vanaf die enkle tot onder die knieskyf. Sewe mededingende langafstand atlete (lengte : 176.0 ± 8.6 cm; liggaams massa: 92.5 ± 11.8 kg; VO2maks: 45.7 ± 5.0 mL.kg-1.min-1) tussen die ouderdomme van 36 en 51 jaar, het aan die studie deel geneem. Die wedlopers moes ‘n twee-uur lange trapmeul toets voltooi, teen 70% van hul vooraf bepaalde maksimum aerobiese kapasiteit. Dit is gevolg deur ‘n gemonitorde 72-uur herstel periode. Die eerste deel van die twee-uur hardloop sessie was ‘n 90-minuut afwisselende opdraende en afdraende hardloop stel, wat gevolg is deur a 30-minuut afdraande deel. Elke deelnemer was sy eie kontrole en het op twee geleenthede die Stellenbosch Universiteit se Sport Fisiologiese Laboratorium (Suid Afrika) besoek. Die twee besoeke is tussen 7 en 28 dae geskei. Een toets is met kompressie sokkies gedoen (23 – 32 mmHg) en die ander sonder. Die toetse het die volgende behels: laer been omtrekke (enkel, kuit, middel- and bo dy), die versameling en ontleding van bloed monsters vir plasma laktaat, laktaat dehydrogenase and kreatine kinase konsentrasies en die voltooing van subjektiewe vraelyste oor die graad van spierpyn ervaaring (“visual analog scale” (VAS)). Die onderlyf funksionele vermoëns is bepaal met ’n tyd tot uitputtings traptoets, ‘n vertikale sprong toets en ‘n gewysige sit-en-strek soepelheids toets. Data is voor die oefeninge in gevorder asook direk daarna, en gedurende die 72 uur na die trapmeul draf. Die metings vir die tweede sessie is herhaal. Die hoof uitkomste van die studie het gewys dat die twee-uur trapmeulsessie het spierpyn veroorsaak, met en sonder die kompressie sokkies. Die bewys hiervan was ‘n betekensvolle toename in plasma kreatien kinase (CKp) oor die tydperk van albei oefening toetse (P<0.05). Die kompressie sokkies het die swelling in die kuitspiere verminder, in vergelyking met die toetse sonder kompressie sokkies (41.0 ± 0.2 vs. 41.5 ± 0.5 mm; P < 0.002). Wedlopers met die kompressie sokkies het minder spierseerheid en ongerief aangeteken toe hulle knie beweegings gedoen het op 24 en 48-uur na die twee-ure trapmeul toets (1.2 ± 1.6 vs. 3.8 ± 2.4 cm op VAS en 0.9 ± 1.8 vs. 3.0 ± 2.6 cm op VAS, onderskeidelik; P < 0.05). Betekenisvolle verskille is waargeneem tussen die toetse met en sonder kompressie sokkies, op 24-uur na die twee-ure toets gedurende rus (0.1 ± 0.2 vs. 0.4 ± 0.8 cm op VAS; P = 0.02) en met strek oefeninge (1.9 ± 1.2 vs. 3.5 ± 2.5 cm op VAS P = 0.02). Die pyn wat ervaar was met drukking, was betekenisvol minder met die kompressie sokkies op 24 (307 %) en 48-uur (237 %) na die trapmeul sessie (P < 0.05). Bloed laktaat konsentrasie in die sirkulasie was verlaag gedurende die akute fase van die herstelings periode op 10 (1.8 ± 0.5 vs. 2.2 ± 0.9 mmol.L-1; P = 0.05) en 30 minute (1.8 ± 0.5 vs. 2.4 ± 0.4 mmol.L-1; P = 0.01) na die hardloop sessie, sowel as die plasma kreatine kinase konsentrasie was statisties betekenisvol laer by 24 uur (238.3 ± 81.3 vs 413.3 ± 250.8 eenhede L-1; P = 0.005) na die hardloop sessie met die kompressie sokkies. Die twee-ure trapmeul toets en die kompressie sokkies het geen betekenisvolle invloed gehad op die wedlopers se onderlyf ledemate se plofkrag, uithouvermoë of soepelheid (P > 0.05) nie. Kompressie sokkies het gewys dat dit potensiaal het om met herstel te help na lang en harde oefening in geoefende middeljarige atlete. Nietemin is daar verdere wetenskaplike navorsing nodig om dit te bevestig. Wedlopers het nie addisionele vermoeienis van die drukking van kompressie sokkies ervaar nie. Sterker drukkende kompressie sokkies sowel as die sielkundige invloed van die sokkies benodig verdere navorsing.spierpyn ervaaring (“visual analog scale” (VAS)).
