Figures & data
Figure 1. Flow diagram of the study selection process.
Table 1. Summary of the articles reviewed (n = 10) with an overview of the participants, the experimental protocols with the time-of-day, exercise mode, and repeated-sprint protocol design and variables examined, and the main findings related to time-of-day in relation to each variable. Statistical significance (p < .05) is indicated in bold. Statistical “trend” or “marginal significance” in italic (0.10 > p > .05).
Table 2. Mean ± SD values for all repeated-sprint performance variables measured in the morning and the evening in each sprint. Papers by Zarrouk et al. (Citation2012) and Lopes-Silva et al. (Citation2019) failed to disclose any data within their manuscripts and were therefore not added to the Table. – indicates missing data.
Table 3. Detailed information related to randomization, counterbalancing, record of light intensity, control of meals, control of room temperature, control of sleep and fitness for articles related to chronobiology (time-of-day).
Table 4. Results of the detailed methodological quality assessment scores based on a modified 26-item Downs and Black (Citation1998) checklist.
