“…Still, the current decrement is higher than the 7 % sprint decrement found in upper-body trained ice sledge hockey players during maximal double poling on ice using an almost identical protocol (Sandbakk et al 2014). Even though the majority of the decrements during such protocols have been explained by incomplete resynthesis of PCr between the sprints (Mendez-Villanueva et al 2012;Bishop et al 2003), the larger sprint decrement found here compared to previous studies requires further explanation. First, this study examined power output decrement and not Another potential factor may be the low muscle mass that produces these high workloads.…”

sprint decrement of 11.7 ± 4.1 %. Cycle rate remained unchanged, whereas work per cycle progressively decreased (P < 0.05). m. triceps brachii and m. latissimus dorsi were highly desaturated already after the first sprint (all P < 0.05), whereas the response was delayed for m. biceps brachii and m. vastus lateralis. Correspondingly, increases in VO 2 mainly occurred over the first two sprints (P < 0.05) and plateaued at approximately 75 % of VO 2peak . 1RM correlated with power during the first four sprints and with average sprint power (r = 0.71-0.80, all P < 0.05), whereas VO 2peak correlated with power in the last three sprints (r = 0.60-0.71, all P < 0.05). Conclusions The main decrement in upper-body sprint performance was evident in the first five sprints, followed by highly desaturated muscles and a plateau in pulmonary oxygen uptake already after the first 2-3 sprints. While high maximal strength seems important for producing power, aerobic capacity correlates with power in the last sprints.Keywords Cross-country · Skiers · Cycle rate · Maximum strength · Oxygen saturation · Oxygen uptake · Power output Methods Twelve male elite cross-country skiers performed eight 8-s maximal poling sprints with a 22-s recovery while sitting on a modified SkiErg poling ergometer. Force, movement velocity, cycle rate, work per cycle, oxygen saturation in working muscles and pulmonary oxygen uptake were measured continuously. A 3-min all-out ergometer poling test determined VO 2peak , and 1 repetition maximum (1RM) strength was determined in a movementspecific pull-down. Results Average sprint power was 281 ± 48 W, with the highest power on the first sprint, a progressive decline in power output over the following four sprints, and a Abbreviations ATTCommunicated by Jean-René Lacour.

“…The intra-and extracellular buffer systems act to reduce the build-up of free H + during high-intensity exercise and may therefore be important in maintaining repeated-sprint performance. Indeed, Bishop et al 7 have reported a significant relationship between RSA and both change in blood pH and in vivo muscle buffer capacity 8 . The intracellular accumulation of H + also depends on the extracellular H + concentration.…”

The aim of this study was to determine the individual variability in time to peak pH after the consumption of a 300mg . kg -1 dose of sodium bicarbonate (NaHCO 3 ). Seventeen active males volunteered to participate in the study (mean ± SD: age 21.38 ± 1.5y; mass 75.8 ± 5.8kg; height 176.8 ± 7.6cm). Participants reported to the laboratory where a resting capillary blood sample was taken aseptically from the fingertip. After this, 300 mg . kg -1 of NaHCO 3 in 400ml of water with 50ml of flavoured cordial was ingested.Participants then rested for 90 min during which repeated blood samples were procured at 10 minute intervals for 60 mins and then every 5 min until 90 min. Blood pH concentrations were measured using a blood gas analyser. Results suggested that time to peak pH (64.41±18.78 min) was highly variable with a range of 10-85 min and a coefficient of variation of 29.16%. A bi-modal distribution occurred, at 65 and 75 min. In conclusion, researchers and athletes, when using NaHCO 3 as an ergogenic aid, should determine, in advance their time to peak pH to best utilise the added buffering capacity this substance allows.

“…The very few studies that examined the effect of music on supra-maximal anaerobic exercise yielded conflicting results [9,26]. In recent years, the use of repeated sprint tests (RST) has gained popularity among coaches and athletes as a method of evaluating repeated sprint ability (RSA), that is used frequently in multi-sprint sports like soccer, basketball, and hockey [e.g., 1,3,23].…”

We examined the effect of motivational music on repeated sprint ability (RSA) in a full squad of junior top national level league basketball players. Participants performed two repeated sprint tests (RSTs), with and without motivational music, at random order, during the end of the basketball season. The RST included 12 X 20 m runs departing every 20 s. There were no significant differences in ideal sprint time, total sprint time and performance decrement between RST with or without music. However, when we compared each sprint during the RST, the last two sprints (sprints number 11 and 12) were significantly faster with, compared to without, music (p<0.01). We conclude that music led to improved sprint performance towards the end of RST, suggesting, probably, beneficial effect mainly on aerobic components of repeated sprint ability. Therefore, music can be used during basketball training, hoping that improved training ability will convert also to better game performance.
