Responses in creatine kinase (CK) activity levels in serum before and 1 hour (1h), 1 day (1d), 2 days (2d), 4 days (4d), and 7 days (7d) after a damaging bout of low-load BFR-RE. Figure based on data from individuals in the study of Sieljacks et al. (2016). Note the differences between individuals, and also in the time-course of the responses in the two participants who were “high-responders” (CK > 19,000 U/L). The upper detection limit for the CK essay in this study was 20,000 U/l, and one of these two individuals may have exceeded this limit. Serum myoglobin showed similarly high increases (data not shown).

Small moderately strongly to strongly NCAM-positive muscle fibers from a subject in the study of Bjørnsen et al. (2019). The biopsy was taken 3 days after the last training week. Note central/non-peripheral myonuclei in several of the NCAM-positive fibers. The section was re-photographed (due to loss of the original pictures) after several years in the freezer, and the positive staining would likely have been even stronger if the section was new. Red = laminin, green = NCAM, and blue = DAPI. Picture cropped from 10× original. Picture courtesy of Mathias Wernbom.
