(1) Background: post-activation potentiation (PAP) plays an essential role in enhancing athletic performance. Various conditioning activities (CAs) have been developed to generate PAP before training or competitions. However, whether extra equipment can enhance the effectiveness of CAs is understudied. Hence, this systematic review aims to introduce and examine the effectiveness of blood flow restriction-based conditioning activities (BFR-CAs). (2) Methods: a literature search was conducted via Web of Science, PubMed, SPORTDiscus, and CNKI (a Chinese academic database). The systematic review included the literature concerning BFR-CAs and non-BFR-CAs. The methodological quality of included studies was considered to be “moderate quality” and “good quality” based on the Physiotherapy Evidence Database Scale. (3) Results: five studies were included in this study. Four studies were on lower limb strength training, and three of them suggested a greater PAP in BFR-CAs than in non-BFR counterparts. One study on upper limb strength training also supported the advantage of BFR-CAs. (4) Conclusions: BFR-CAs may be an emerging and promising strategy to generate PAP. Compared with non-BFR-CAs, BFR-CAs might be more efficient and practical for inexperienced sports people or athletes in non-power sports.

Exercise procrastination refers to the unjustified delay in initiating or continuing planned physical activity despite being aware of its necessity, which undermines adherence to exercise and diminishes health benefits. To fill the gap in measurement tools for exercise procrastination among Chinese university students, this study translated and examined the Chinese version of the Procrastination in Exercise Scale (PES). A cross-sectional survey was conducted among Chinese university students (N = 440), and a subsample (n = 36) completed a retest after two weeks. Confirmatory factor analysis (CFA) was used to evaluate the scale’s structure and model fit. Internal consistency and test–retest reliability were assessed, and convergent validity was examined using the Irrational Procrastination Scale (IPS). Results showed that, after allowing the residuals of Items 1 and 3 to correlate, the model achieved acceptable fit indices, and the scale demonstrated good internal consistency. PES was moderately correlated with IPS, providing preliminary evidence of convergent validity. However, the intraclass correlation coefficient (ICC) for the two-week retest was relatively low, suggesting short-term state fluctuations and insufficient score stability. Overall, the Chinese version of the PES exhibited acceptable structural validity and strong internal consistency among university students, aligning theoretically with general procrastination. Nevertheless, its temporal stability and cross-situational generalizability require further verification in larger samples and at multiple time points.
