Functionality Under Exercise Load

As part of the study titled “Research on the Functionality of Fucoidan Mixture Under Exercise Load,” a preliminary test was conducted on two healthy adult subjects. The participants underwent a 10-minute ergometer exercise with a gradually increasing workload. During and after the exercise, temporal changes in blood parameters were monitored and analyzed.
The results of the test are summarized below.

※Blood samples were collected before the meal. Both subjects consumed the same standardized meal, followed by a 2-hour rest period. Blood was then drawn immediately prior to the start of the exercise load.

Blood glucose levels dropped immediately following the application of the exercise load and returned to pre-exercise levels within approximately 40 minutes. Regarding lactic acid levels, both subjects experienced a sudden increase immediately after the exercise load. Despite slight individual differences, lactic acid levels returned to baseline levels in approximately 120 minutes.

Both adrenaline and noradrenaline rose immediately after the exercise load, and returned to baseline levels over a short period of 20 minutes.

NK cell activity decreased after the meal and then increased immediately following the exercise load. However, the activity levels gradually declined over time after this initial rise. Notably, 20 minutes after exercise, NK cell activity dropped to a level lower than the pre-meal baseline and remained at that reduced level thereafter.

Levels of immune cells—excluding eosinophils—increased immediately after the application of the exercise load. These levels returned to baseline within 20 to 60 minutes, but then showed a secondary rise at the 120-minute mark.
