Welcome On behalf of the European College of Sport Science (ECSS) and VU University Amsterdam we welcome you to Amsterdam for the 19th annual congress of the ECSS. The two hosting partners, VU University Amsterdam and VU University Medical Center Amsterdam, have a long-standing reputation with excellent research in sport science. We have MOVE research institute amsterdam, which performs fundamental research on human movement with focus on rehabilitation, regenerative medicine and sports. Besides that there is the Institute for Health & Care Research (EMGO+) with research is on public health, primary care and long-term care. We combine various fields of study and innovative techniques with focus on implementation and use in society. The Amsterdam congress provides an outstanding scientific programme that emphasizes the current state of knowledge in sport science. The congress will feature four plenary sessions and 36 invited symposia on topical issues in the field. In total more than 2400 abstracts have been submitted from 67 countries. Free communications have been distributed among 74 oral and 106 mini-oral sessions. There are also 500 undebated E-posters, which can be viewed on large screens. The capital of The Netherlands, host city for this 19th congress, is known for its beauty and historic significance. No-one can visit Amsterdam without having mounted on a boat for a trip on the cosy canals. Viewing the city from the water gives a total different experience. Enjoy the finest works of art, the fruit of the blossoming 17th century in the Netherlands. In that time Amsterdam was a center where intellectual, artistic and trading activities converged. Rembrandt, Vermeer and other successful painters made the city Europe’s leading center of art. Later, freethinkers like the philosopher Baruch de Spinoza found a warm welcome in Amsterdam, where religious tolerance was an important issue. You can learn about it in, amongst others, the Rijksmuseum and the Spinoza House. Amsterdam will offer you a high-quality scientific programme, we anticipate that the 19th annual congress of the ECSS will be outstanding. On behalf of the ECSS and the local organizers we wish you great stay in Amsterdam. Enjoy sport science around the canals. Prof. A. de Haan (VU University Amsterdam)

The Jikeikai University School of Medicine PURPOSE: An exercise regimen has long been considered an important component in the therapy for diabetes, as it has been found to improve insulin sensitivity, increase muscle mass, and assist in weight control. Further, van Dam and Feskens found that moderate coffee consumption helps reduce the risk of type 2 diabetes. Therefore, by using Otsuka Long-Evans Tokushima fatty (OLETF) rats, this study examined the effects of a combined treatment with exercise and caffeine on renal pathophysiological findings and urinary albumin excretion (Ealb) as well as body composition, glucose intolerance (GI), and dyslipidemia associated with diabetes mellitus. METHODS: Twenty-four OLETF rats were divided into the following groups: sedentary (Sed), exercise (Ex), caffeine (Caf), and a combination of exercise and caffeine group (Ex & Caf). All treatments were performed from 25 to 29 weeks of age. Rats in the Caf and Ex & Caf groups were fed rat chow containing 0.25% caffeine based on a previous study. Rats in the Ex and Ex & Caf groups were permitted to voluntarily run every day. Body weight (BW) and blood pressure (BP) were measured once every week. Before and after the treatment, 24 h urine samples were collected for measuring the Ealb. Whole-body subcutaneous fat mass (SFM), visceral fat mass (VFM), and lean body mass (LBM) were measured before and after the treatment using a radiographic computed tomography scan. The animals were sacrificed by exsanguination after the completion of treatment. The kidneys were removed for performing renal pathophysiological analysis; blood samples were collected for measuring the fasting blood glucose (FBG), insulin and lipid concentrations. RESULTS AND DISCUSSION: The BW, SFM, and VFM reduced significantly in the Ex, Caf, and Ex & Caf groups, whereas these variables increased significantly in the Sed group after treatment. There was no change in systolic BP (SBP) during the treatment period in the Ex, Caf, and Ex & Caf groups, but the Sed group had a significantly higher SBP compared with the pre-treatment level. The Ealb of the Caf and Ex & Caf groups significantly decreased compared with the pre-treatment levels, and the mean mesangial area and glomerular basement membrane thickness were significantly lower in the Caf and Ex & Caf groups than in the Sed and Ex groups. The FBG and dyslipidemia remarkably improved in the Ex and Ex & Caf groups after treatment. CONCLUSION:Treatment with caffeine alone inhibited the progression of DN, whereas exercise alone did not inhibit the progression of DN. Our results suggest that a combined treatment with caffeine and exercise is more efficacious than treatment with either caffeine or exercise for improving DN as well as GI and dyslipidemia in OLETF rats.

EFFECTS OF CAFFEINE CONTAINING ENERGY DRINK ON FEMALE VOLLEYBALL PERFORMANCE Pérez López, A.1, Salinero, J.J.2, Valadés, D.1, Abián Vicén, J.2, Lara, B.2, Hernández, C.3, Areces, F.2, González, C.2, Del Coso, J.2 1. University of Alcalá; 2. Camilo José Cela University; 3. Polytechnic University of Madrid. Introduction: Ingestion of caffeine containing products has been widely tested in endurance sports (Jenkins et al., 2008). However, the effect of caffeine consumption on team-sport performance remain to be evaluated (Astorino & Roberson, 2010). In volleyball, only one study has tested a caffeine containing beverage on male volleyball players (Pérez-López et al., 2013). Therefore, the aim of this study was to evaluate the effect of caffeine containing energy drinks on female volleyball players’ performance. Methods: Double-blind, placebo controlled and randomized experimental design was performed. On two different days, 13 semi-professional female volleyball players (25.2 ± 4.8 yrs; 174 ± 9 cm; 64.4 ± 7.6 kg) ingested 3 mg of caffeine per kg of body mass in an energy drink (Fure®, ProEnergetics) or the same drink without caffeine (placebo). After 60-min for caffeine absorption, athletes performed seven tests: a) standing spike; b) spike jump (SPJ); c) block jump (BJ); d) squat jump (SJ); e) counter-movement jump (CMJ); f) jumping spike; g) agility T-test. Later, a simulated volleyball match was played and recorded. Afterward time motion analysis was done. Results: In comparison to the placebo drink, the ingestion of caffeinated energy drink improved standing (19.2 ± 2.1 Vs. 19.7 ± 1.9 m•s-1; P = 0.023) and jumping spike ball velocity (17.9 ± 2.2 Vs. 18.8 ± 2.2 m•s-1; P = 0.038). Also, it enhanced mean jump height of SPJ (43.3 ± 4.7 Vs. 44.4 ± 5.0 cm; P = 0.024), BJ (35.2 ± 5.1 Vs. 36.1 ± 5.1 cm; P = 0.044), SJ (28.1 ± 3.2 Vs. 29.4 ± 3.6 cm; P = 0.028), CMJ (32.0 ± 4.6 Vs. 33.1 ± 4.5 cm; P = 0.018) and time to complete T-test was reduced (11.1 ± 0.5 Vs. 10.9 ± 0.3 s; P = 0.036). Finally, during the simulated match, when the energy drink was ingested positive game actions were more frequent (34 ± 9 Vs. 45 ± 9 %; P < 0.001); whereas negative game actions were diminished (28 ± 7 Vs. 14 ± 9 %; P < 0.001). Discussion: Pre-exercise ingestion of a caffeinated energy drink improved jump height, spike and displacement velocity as in male volleyball players (Pérez-López et al. 2013). Moreover, in females, higher jump spike velocity, spike and block jump height, and a reduction in frequency of negative actions during the match were also observed. Thus, caffeinated energy drink was effective to improve female volleyball players’ performance. References: Astorino TA, Roberson DW. (2010). J Strength Cond Res, 24(1), 257-65.

MO-PM01 NU Ergogenic Supplements 1 COMBINED EFFECTS OF ICE SLURRY AND CAFFEINE INGESTION ON THERMOREGULATION AND EXERCISE CAPACITY IN A WARM ENVIRONMENT Hasegawa, H. Hiroshima University Introduction Caffeine is widely consumed as an ergogenic aid to improve cognitive and physical performance. Endurance performance can be improved when humans are administrated with approximately 3 to 9 mg/kg caffeine. Internal cooling such as cold water ingestion has been recently attracted attention. A more aggressive internal pre exercise cooling process appears to occur with the ingestion of an ice slurry mixture (Siegel and Laursen, 2012). The purpose of this study was to investigate the combined effects of ice slurry and caffeine ingestion on thermoregulation and endurance exercise capacity in a warm environment. Methods One hour before exercise, nine male subjects ingested either 6 mg/kg caffeine or placebo. Subjects then ingested either 15 g/kg ice slurry (−1°C) or water (37°C) during 60 min of rest. Subjects completed four experimental cycling trials at 60% maximum voluntary exercise to exhaustion at 30°C and 70% relative humidity. Four experimental conditions were set for placebo and water ingestion (CON), caffeine and water ingestion (CAF), placebo and ice slurry ingestion (S), caffeine and ice slurry ingestion (SCAF). Exhaustion was considered to have occurred when the subject was unable to keep pace or rectal temperature reached at 39.5°C. Results In the SCAF, time to exhaustion was significantly longer than that of the CON (SCAF: 67.4 ± 12.3 min, CON: 51.6 ± 11 min). The decrease in rectal temperature during rest in S and SCAF were significantly greater than that of CON and CAF. Rectal temperature, skin temperatures and heart rate were increased during exercise, but these physiological responses were not different between the conditions. In the CAF, S and SCAF, rating of perceived exertion from 10 to 40 min exercise were significantly lower than that for the CON. The rate of attainment of critical temperature in SCAF was higher (CON: 11%, CAF: 22%, S: 0%, SCAF: 44%). Discussion Both ice slurry and caffeine ingestion before exercise had a positive effect for the exercise capacity in a warm environment. Combined methods of ice slurry and caffeine ingestion increased endurance exercise due to the increase in heat storage capacity and decrease in subjective responses, and delayed the onset fatigue. The present results were not partly consisted with the results that caffeine induced an additional increase in core temperature (Roelands et al, 2011). Although many subjects in SCAF were able to continue exercise, they had to stop exercise because their core temperature reached at the critical level. It is necessary for attention to be paid if we use combination of ice slurry and caffeine ingestion during exercise in a warm environments. References Siegel R, Laursen PB. (2012).

HEALTH BENEFITS OF CREATINE SUPPLEMENTATION WITH AND WITHOUT ALLFA-LIPOLIC ACID IN OVERWEIGHT SEDENTARY MALES: PILOT STUDY Polyviou, T.1, Celis Morales, C.1,2, Pitsiladis, Y.3, Malkova, D.1 1; MVLS (Glasgow, UK), 2; HNRC (Newcastle, UK), 3; BCRM (Brighton, UK) Introduction Creatine (Cr) supplementation, used for lean body mass and exercise performance enhancement (Harris et al., 1992) can also improve insulin sensitivity (Eijnde et al., 2001). However, in the absence of exercise uptake of Cr is limited (Harris et al., 1992). The purpose of this study was to determine whether health related benefits of Cr supplementation can be improved when Cr is taken with alpha lipoic acid (Ala), an agent known to enhance Cr uptake by skeletal muscle (Volchegorskii et al., 2011). Methods Participants (Cr group (n=7): age 33.6±6.8 y, BMI 28.8± 4.7 kg/m2¬; Cr/Ala group (n=7): age, 37.8±9.6, BMI 29.4±2.8 kg/m2¬) attended the laboratory after a 12-hour fast and performed an oral glucose tolerance test (OGTT) before and after four weeks of supplementation with either Cr (20 g/day for the first week and 5 g/day for 3 weeks) or Cr/Ala (same as Cr group plus 1000 mg/day of Ala). Mean values of glucose and insulin during OGTT and insulin sensitivity index (Matsuda and De Fronzo, 1999) were calculated from fasting and post-glucose plasma glucose and insulin concentrations. Results Mean glucose response during OGTT was improved with Cr (Pre, 5.3±0.8; Post, 4.8±0.9; P = 0.04) but not with Cr/Ala (Pre, 5.9±1.9; Post, 5.6±1.9; P = 0.71) supplementation while mean insulin responses were not significantly different between Cr (Pre, 8.5±4.7; Post, 7.3±2,4; P = 0.73) and Cr/Ala (Pre, 8.4±1.2; Post, 8.0±1.2; P = 0.68) trials. Insulin sensitivity index was not modified by supplementation with either Cr (Pre, 6.1±3.4; Post, 7.1±2.1, P=0.78) or Cr/Ala (Pre, 5.2±1.2; Post, 5.6±2.0, P = 0.58). Discussion Data obtained in this study suggest that Cr supplementation can improve glucose tolerance of overweigh sedentary individuals and that addition of Ala to Cr supplementation brings no further metabolic benefits. A randomised control trial with a bigger sample size should be carried out to confirm these findings.

PRE-EXERCISE ACUTE CREATINE SUPPLEMENTATION EFFECTS ON REPEATED SPRINT PERFORMANCE IN CREATINE LOADED AND UNLOADED YOUNG BASKETBALL PLAYERS Tok, O., Turnagol, H., Kosar, N. Health Science Institute Introduction Creatine has become one of the most popular dietary supplements in the sports nutrition market. The new forms of creatine has been investigated in many research but the efficacy of the liquid form of creatine present in today’s marketplace as a dietary supplement is less clear. Therefore, the aim of this study is to determine the pre-exercise acute creatine supplementation effects on repeated sprint performance in creatine loaded and unloaded young basketball players. Methods This research involved 13 trained male (17.46 ± 0.66 years, 194.2 ± 4.6 cm, 83.79 ± 9.12 kg ve 6.31 ± 2.29 training age). The study was designed as randomised, double blind, crossover and placebo controlled. Athletes were divided into two groups and attended to 3 performance test (10x15m repeated sprint test with 30sn intervals) on separate days: baseline, after creatine loading (0.3g/kg/d, 5days) and after liquid creatine supplementation (5 ml, sublingual). Pre and post test venous and finger blood samples were collected to determine lactate dehydrogenase, creatine kinase, serum creatinin and serum electrolyte concentrations and lactate levels. Moreover, athletes’ heart rate, body composition and urine density were determined. The study’s washout duration for crossover design took 3 weeks (21 days). Results Results showed that there were no significant difference in sprint time, lactate, kreatine kinase levels and body composition measurements among the groups (p>0,05). It is observed that post-exercise serum lactate dehydrogenase levels decreased and sodium levels increased in creatine unloaded group with acute creatine supplementation (p 0,05) but fasting NES1 had higher concentrations in OB than EUT (4,22+0,88 vs. 2,41+0,56 ng/ml; p < 0,001). A negative correlation between fasting plasma concentrations of NES1 and GRE (only in EUT) and a positive association with BMI and NES1 (for both groups) were observed. Discussion This study showed that acute aerobic exercise induced suppression of appetite and GRE in EUT, which does not occur in OB. Indeed obese may be less responsive than lean subjects to these appetite hormones. The excess of fat might be hampering the hypothalamus signaling from peripheral tissues and/or generating a negative feedback to the hormone-producing cells (Briggs et al, 2010). Chronic exercise may be necessary to induce some appetiterelated hormones controlling. References Kojima, M; Hosoda, H; Date, Y; Nakasato, M; Matsuo, H; Kangawa, K. Nature, 402, 656-660.

EFFECTS OF 6 MONTH OF AIT ON FAT METABOLISM IN THE SKELETAL MUSCLE OF METABOLIC SYNDROME PATIENTS Fernández Elías, V.E., Guadalupe Grau, A., Ortega, J.F., Dela, F., Helge, J.W., Mora Rodriguez, R. University of Castilla-La Mancha and University of Copenhaguen Introduction Aerobic exercise training (AIT) improves the health of metabolic syndrome patients1. However, exercise training does not reverse all metabolic syndrome risk factor with dysregulated blood lipids being resilient to improvements. The analysis of muscle cellular metabolism may reveal some of the causes of this resistance. Purpose The aim of the present study was to evaluate the effects of 6 months of AIT on key proteins involved in the regulation and utilization of fat in the skeletal muscle of metabolic syndrome patients. Methods Eleven metabolic syndrome patients (54.5 ± 0.7 yrs old) underwent 6 month of 3 days a week supervised AIT program in a cycleergometer. Cardio-metabolic health was assessed and muscle biopsies were collected from the vastus lateralis prior and at the end of the AIT program. Muscle was analyzed for AMP-activated protein kinase (AMPK), acetyl-CoA carboxylase (ACC), hormone-sensitive lipase (HSL), lipoprotein lipase (LPL), endothelial lipase (EL), citrate synthase (CS) and 3-hydroxyacyl-CoA dehydrogenase (HAD). Results After 6 months of AIT, body fat (4 %) and waist circumference (2 %) were reduced while exercise maximal fat oxidation rate was markedly increased (38%; all p < 0.05). However, body weight, VO2peak, and blood cholesterol did not significantly improve with training. Total AMPK (22%), endothelial lipase protein expression (19%) and CS activity (26%) increased (all p < 0.05). In contrast, HAD activity, AMPK and ACC phosphorylation, and total expression of ACC, HSL and LPL did not change with training. Discussion Six months of AIT in metabolic syndrome patients raised the maximal rate of fat oxidation during exercise without a measurable effect on ß oxidation rate-limiting enzyme (HAD), rate-limiting enzymes in triglyceride lipolysis and fatty acid hydrolysis (LPL and HSL) or ACC. The shift towards higher reliance on fat oxidation during exercise could be mediated by improvements in mitochondrial function (CS), endothelial lipase and amount of total AMPK. It is possible that harder training that increases cardiorespiratory fitness is required to observe significant improvements in muscle fat oxidative machinery. References: 1.

THE RELATIONSHIP BETWEEN SUBCUTANEOUS FAT AND INTRAMUSCULAR LIPID IN HUMAN LIMB. Yoshikawa, M.1, Kurihara, T.1, Taguchi, S.1, Yamauchi, J.2,3, Hashimoto, T.1,3 1Ritsumeikan University, 2TMU, 3FIfSS [Introduction] White adipocyte tissue (WAT) is located in subcutaneous, visceral and muscle. It has been reported that high intramuscular lipid accumulation is related to obesity and insulin-resistant states such as type 2 diabetes. How frequently we activate muscles is a key for proper metabolic regulation. Because total amount of muscle activity in daily life reflects to the muscle volume, metabolic level of upper and lower limbs should be a different level. In theory, a basal metabolic level is lower when muscle volume is small and muscle activity is low, so that body composition of upper and lower limbs in human could be adapted differently over years after becoming bipedal; however, the chronic metabolic responses or body composition of limbs, especially upper limbs, have seldom been studied. Magnetic resonance imaging (MRI) offers to accurately and non-invasively assess regional muscle and fat size and volume. On the other hand, magnetic resonance spectroscopy (MRS) offers to assess metabolism non-invasively, and using single voxel proton MRS can assess the intramuscular lipid. [Purpose] The aim of this study was to examine the quantitative relationship of subcutaneous fat and intramuscular lipid in human limb. [Materials and Methods] Thirty-three healthy young individuals (male: n=11, female: n=22; age, 20.0±1.2 yrs; height, 162.9±6.8 cm; body mass, 55.9±6.7 kg; mean± S.D.) volunteered. Their body composition was measured by MRI and their intramuscular lipid of triceps brachii was measured by 1H-MRS. For a measurement of MRI, subjects were laid supine on the examination table of a 1.5-T MR system (Signa HDxt, GE Healthcare). The axial image of upper arm was acquired to measure the crosssectional area of muscle, fat and bone. The images at the midpoint of upper limb was selected due to that the anatomical crosssectional area (ACSA) of the muscle is the largest at this point. For a measurement of 1H-MRS, image-guided, localized, single-voxel 1HMRS was performed in the triceps brachii muscle. In every subject, voxels were carefully placed at the same position for repeated measurements. [Result] ACSA of upper arm measured by MRI showed that a subcutaneous fat was 21.7±7.1 cm2, which corresponds to 38.3±15.5% in ACSA of upper arm. Intramuscular lipid in the triceps brachii muscle measured by 1H-MRS was 567.9±398.7 au. The subcutaneous fat in ACSA of upper arm and intramuscular lipid in the triceps brachii muscle were significantly correlated each other (r=0.52). In addition, female tended to have higher amount of intramuscular lipid than male, and the subcutaneous fat in ACSA of upper arm was significantly higher for female than for male (p
