“…The endurance tests were performed using a Cyclus2® ergometer (RBM elektronik-automation GmbH, Leipzig, Germany) so that both participants could complete all tests on their own road bike with their own individual settings. Before the start of the study, the participants' positions on their bikes were checked according to common practice (Bartaguiz, Dindorf, Dully, Becker, & Fröhlich, 2022).…”

The use of single supplements to enhance performance is widespread among athletes. The aim of this study was to increase knowledge about the combined effects of caffeine and New Zealand blackcurrant (NZBC) dietary supplements. In this counterbalanced alternating treatment single-case design, two participants each underwent four phases of four sessions in a double-blind, randomized order. After a 3-week pre-test phase, the supplement combinations of placebo/placebo, caffeine/placebo (5 mg/kg), NZBC/placebo (600 mg), and caffeine/NZBC (5 mg/kg + 600 mg) were taken and weekly performance tests were conducted to examine their effects on relative power (W/kg) during a 20-minute time trial on a bicycle. Data were analyzed descriptively and using the Tau-U calculator from Single Case Research. The ergogenic effect of caffeine was confirmed in both participants, with increases of 3.3% and 6.5%, while the positive effect of NZBC on performance was only seen in one participant (13.4%). The combination of caffeine and NZBC again increased performance in both participants (2.2% and 19.2%), but the data only showed a near additive effect of the supplements in one participant. The participants did not show a consistent performance improvement with the combined intake of the supplements caffeine and NZBC. Further studies are required to confirm or refute this evidence of the synergistic effects of these supplements.

The use of isolated supplements to enhance performance is widespread among athletes. The aim of this study was to increase knowledge about the combined effects of caffeine and New Zealand blackcurrant (NZBC) dietary supplements. In this study, two subjects each underwent four phases of four sessions in a double-blind and randomized alternating treatment single-case design.

This study investigates the intricate dynamics of rank-order stability by examining the current-to-final rank difference (CFRD) during 24-hour cycling races, especially how different team sizes and performance levels contribute to the temporal trends in CFRD. A comprehensive dataset covering five consecutive years (2019–2023) of a 24-hour cycling race on a 17.9 km repetitive driven road track, encompassing diverse team sizes (solo rider, or teams of 4 and 10), is used. The results indicate significant interactions between time, team size, and performance, with CFRD consistently decreasing across team sizes and performance levels over the race duration. Temporal analysis unveils critical phases with pronounced changes in CFRD, providing nuanced insights into the evolving dynamics of 24-hour races. Notable distinctions emerge between team sizes, with solo riders exhibiting unique patterns. High-performance teams consistently maintain a lower CFRD, exhibiting more predictable outcomes over the race duration. Overall, this study advances our understanding of endurance team cycling, and offers valuable insights for strategic decision making and race optimization.
