Background. High intensity physical exertion is a stress for the body; Lepidium meyenii (LM) is known for its antistress effects.
Aims. This study aimed to highlight phytotherapic modulation, under the action of a Lepidium meyenii product (LM; LMP), on anxiety (A), glycemia (G) and salivary pH (SpH), in physical stress caused by walking very fast on the treadmill, in sedentary subjects.
Methods. 24 healthy male volunteers were randomized to: a control group (C=8), without treatment; a group who received LMP 12 days (LM1=8); a group who received LMP 21 days (LM2=8). Stress model: walking very fast on the treadmill. Analyzed indicators: anxiety (A), glycemia (G) and salivary pH (SpH). Determinations: before LM treatment (T1), 15 minutes (T2) before, 30 minutes (T3) and 4 hours (T4) after the physical effort. The results obtained were analyzed using the SPSS statistical package.
Results. For C, compared to T1, the most significant were: increases for A (T2), G (T3); decrease for SpH (T3). In LM1 and LM2, values were significantly: low for A (T2), G (T3); high for SpH (T3). LM2 impact was greater than LM1. LM1/ LM2 influence was more important on A.
Conclusions. 1) Dynamic developments of A, G, SpH were different for C, LM1/ LM2. 2) LM significantly reduced A/ G, increased SpH, with a more important influence on A. 3) LM2 effect was more intense than LM1. 4) We suggest LM may be useful in A, G, SpH modulation, in stress caused by walking very fast on the treadmill, in sedentary people, but further research is needed.
