q2 · i? · review · r3

Review synthesis of frequency-domain HRV findings; the LF/HF ratio was the most popular frequency-based metric (n = 11 articles). The review reports "the ratio proved to increase significantly in participants when performing or training under stressful situations".

"Within all applicable studies [11, 23, 60, 73, 74, 76, 78, 83, 86], the ratio proved to increase significantly in participants when performing or training under stressful situations."
