Exploratory Study on the Improvement of Jump Performance Through Exposure to Schumann Frequencies.

Studies have demonstrated that being exposed to electromagnetic fields (EMFs), especially to Schumann frequencies, may affect physiological functions. This study investigated the effects of very low frequencies (Schumann - 7.83 Hz) and low intensity (1 μT) on short- and mid-term physical jump performance of male teenagers aged 12 to 15 years in Colegio Andrés Escobar in Bogotá. A group of 20 participants was divided into two groups: one exposed to the EMFs (irradiation group) and another serving as a control without additional irradiation. Over the course of eight weeks, one-hour exposure sessions took place once per week, followed by performance evaluations. The participants performed three jumps of each type (six jumps total) per session. In sum, they completed 48 jumps (24 countermovement jumps and 24 squat jumps). The results showed a statistically significant increase in jump performance for the irradiation group, with an increase of 27% for the countermovement jump and 12% for the squat jump. In comparison, the control group exhibited non-significant decreases in both types of jumps, ranging from -3 to -1%. Although this study focused on athletic jumping tasks, the results provide evidence for a possible effect of EMFs on neuromuscular performance, with potential relevance for both athletic training and medical rehabilitation.
