Background. Rhodiola rosea is a well-known adaptogen, and among its actions are those of antistress and anti-fatigue protection. Aims. The aim of the present research is the evaluation of the number of PubMed publications regarding Rhodiola rosea’s (RR) relationship with stress (S), physical fatigue (F) and endurance (E). Methods. Analysis was performed: a) for specific selected keyword combinations (KWC): “RR” (RR), “RR and stress” (R+S), “RR and cortisol” (R+C), “RR and anxiety” (R+A),”RR and physical fatigue” (R+F),”RR and endurance” (R+E); and for some filter and subfilters provided by the PubMed site. Results. A) Analysis of the number of publications (N). For RR, we found the largest: period of publication (54 years), N (743), average number of publications per publication period (13.76). Relative to RR, the highest % was for R+S (23.28%). B) Analysis of filters. a) Text availability. The percentage of the number of abstracts (A) was high and close to the coresponding N (NC). The highest % of RR was for R+S in A (23.52%), full text (FT) (27.8%) and free full text (FFT) (27.23%). b) Species. The highest number was for RR, both in animals (An) (322) and humans (H) (211). The highest % of RR was for R+S, both in An (24.53%) and H (32.7%). c) Sex. The highest number was for RR in H males (HM) (60), H females (HF) (45) and H males+females (HM+F) (74). The highest % of RR was for R+S in HM (28.33%), HF (31.11%) and HM+F (29.73%). Conclusions. 1) The number of publications for the KWC differed; it was the largest for RR and R+S, smaller for R+F and R+E, and the smallest for R+A and R+C. 2) For all KWC, the number of FFT publications was reduced compared to the total number of publications, the number of A and FT, with a predominance of FFT for R+C as a percentage of NC. 3) Apart from RR and R+S, in which animal research predominated, for all the other chosen KWC, research on human subjects was preferred. 4) Apart from R+F, in which research on females predominated, for all the other chosen KWC, research on subjects of both genders was preferred.

Background. Dance (D) represents a type of sport that can lead to injuries, pain and that is associated with stress (S). Aims. The aim of the present research is the evaluation of research concerns for the relationship between stress and dance. Methods. An analysis of keyword combinations, namely: "stress and dance" (S+D), "stress and dance and injury" (S+D+I), "stress and dance and pain" (S+D+P), "stress and dance and cortisol" (S+D+C), "stress and dance and anxiety" (S+D+A) and "stress and dance and professional" (S+D+PS) was evaluated. Results. There were significant differences between the S+D and the other chosen keyword combinations, S+D+I (0.031), S+D+P (0.006), S+D+C (0.021), S+D+A (0.004) and S+D+PS (0.003). Conclusions. 1) The largest number of publications appeared in the "stress and dance and injuries" keyword combination, which proves the importance of dance and injuries connection. 2) Research concentrates on the connection between dance and pain, the proof being their numerical location, in second place. 3) The analysis of stress elements, such as cortisol and anxiety, can be found in studies relating to dance, the emotional component being more extensively analyzed. 4) The importance of professional dance can be found in the number of publications corresponding to this keyword association, as well as in the percentage of publications including the stress and dance association.

Background. Stress (S) and athletes (A) are subjects of research interest, but the S+A relationship has been little investigated. Aims. The aim of the present paper is the evaluation of research regarding the S+A relationship, by the retrospective analysis of PubMed publications over the past 62 years. Methods. The S+A relationship was analyzed in two types of investigations: A) Analysis of the keyword combination "stress and athletes" by the evaluation of three filters, each with corresponding sub-filters: Text availability, Species and Sex. B) Comparative analysis for the keyword combinations:"stress and athletes" (S+A), "stress and athletes and cortisol" (S+A+C), "stress and athletes and pain" (S+A+P),"stress and athletes and pain test" (S+A+PT) and "stress and athletes and VAS" (S+A+VAS). Results. There are significant differences between the averages per year over 62 years: a) for the total number of publications (N), those with abstract (A) and full-text (FT) respectively, compared to those with free full-text (FFT); b) between studies with human subjects and those with animal subjects; c) between S+A and the other chosen keyword combinations, S+A+C, S+A+P, S+A+PT, S+A+VAS. Conclusions. 1) The total number of publications over 62 years, with the keywords "stress and athletes", is representative, 2448. 2) For the S+A keyword combination, the number of FFT publications is low compared to N and A, which could be an impediment for detailed consultation by those with modest financial possibilities. 3) For studies with S+A keywords, human subjects of both genders were preferred. 4) The publications regarding the evaluation of stress in athletes (through cortisol) and of pain under stress conditions in athletes (through various tests, in particular VAS), although numerically modestly represented compared to the total number of publications relating to stress and athletes, are important, through the role attributed to these parameters.

Background. Music therapy (MT) has been shown to have a beneficial effect on anxiety and cortisol levels. Aims. The objective of the study is to highlight the modulation by MT of anxiety and salivary cortisol in stress induced by short term intense physical exercise, in sedentary subjects. Methods. The subjects (n=22) were selected according to the inclusion criteria of the study. Stress was represented by short term intense physical exercise, performed with a Monark Ergomedic 839E cycle ergometer. The analyzed indicators were anxiety and salivary cortisol. Selected music was Concert No. 21 by W. A. Mozart. Statistical analysis was made on the basis of the Student test. Results. Following administration of MT, anxiety and salivary cortisol were reduced immediately pre- and post-stress compared with subjects who did not follow any treatment. Conclusions. 1). Under the influence of MT, compared with the untreated subjects, anxiety and salivary cortisol were significantly reduced immediately pre- and post-exercise, in stress caused by short term intense physical exercise, in sedentary persons. 2). It was proven that the influence is significantly more intense on anxiety than on salivary cortisol in the moments immediately pre- and post-stress, in the case of MT. 3). There are differences between the experimental group of MT and the untreated control group regarding the dynamic evolution of anxiety, as well as salivary cortisol. 4). We suggest the use of MT in the modulation of stress caused by short term intense physical exercise in persons with a sedentary life-style. [ABSTRACT FROM AUTHOR]

Background. Phytotherapic products may influence the effect of stress on anxiety and salivary cortisol. Aims. The objective of the study is to highlight the phytotherapic modulation of dynamic peri -stress changes induced by intense short duration physical exercise on two parameters (anxiety and salivary cortisol), in sedentary subjects. Methods. The chosen subjects (n=24) were selected according to the requirements of the study. Stress was represented by intense short duration physical exercise, made with a Monark Ergomedic 839E cycle ergometer. The analyzed indicators were anxiety and salivary cortisol. The phytotherapic product (PP) used contained Rhodiola Rosea. Statistical evaluation was made on the basis of Student test. Results. Anxiety and salivary cortisol were reduced immediately pre- and post-stress in subjects who were administered the PP, compared with subjects who did not follow the phytotherapic treatment. Conclusions. 1) Anxiety and salivary cortisol were significantly reduced immediately pre- and post-exercise, in the case of stress caused by intense short duration physical exercise, in sedentary persons, under PP influence. 2) There were differences in dynamic developments between the PP treated group and the untreated group, for anxiety and salivary cortisol. 3) The influence of the PP used was significantly more intense on anxiety than on salivary cortisol, immediately pre- and poststress. 4) The PP used may be an effective, safe and accessible modulation path for stress caused by intense short duration physical exercise in sedentary persons.

Background. Intense short duration exercise is a type of stress, especially for sedentary individuals. Aims. The objective of this study was to reveal dynamic changes comparatively, in stress caused by intense short duration exercise, for two parameters, in physically sedentary persons. Methods. The chosen subjects were selected to meet the requirements of the study. Stress was represented by intense short duration exercise, performed on a Monark Ergomedic 839E cycle ergometer. The parameters analyzed were heart rate and salivary cortisol. Evaluative statistics were based on Student t test. Results. Heart rate presented the most intense significant increase, immediately in the pre-exercise period. Salivary cortisol increased significantly immediately post-stress compared to the pre-stress time. Conclusions. 1) Intense short duration athletic stress has, in sedentary persons, an important impact on heart rate and salivary cortisol. 2) There were differences in the dynamic evolution between heart rate and salivary cortisol. 3) Heart rate variations have shown that in this type of stress, emotional changes are anticipatory. 4) Salivary cortisol changes show that changes in oxidative stress induced by analyzed exercise are more intense post-stress. 5) The results obtained are consistent with the latest bibliographic data on stress caused by exercise. 6) The two studied parameters could be considered important markers of stress induced by intense short duration exercise, for sedentary persons.

Background. A short duration and intense exercise constitutes a type of stress, especially for sedentary individuals. Aims. The objective of this study was to reveal dynamic changes comparatively, in stress, caused by intense and short duration exercise, for two parameters, in physically sedentary persons. Methods. The present study is one of orientation. Subjects chosen were selected to match the requirements of the study. The stress was represented by a short duration and intense exercise, made with a cicloergometru Monark 839e Ergomedic. The parameters analyzed were anxiety and malondialdehyde measured by colorimetric method (after Satoh). Evaluative statistics were based on Student t test. Results. Anxiety presented the most intense significant increase, immediately in the pre-exercise period. Malondialdehyde increased significantly immediately post-stress compared to the pre-stress time. Conclusions. 1) A short and intense athletic stress, has in previously sedentary persons, an important impact on anxiety and malondialdehyde. 2) There were differences of the dynamic evolution between anxiety and malondialdehyde. 3) Anxiety variations have shown that in this type of stress, emotional changes are anticipatory. 4) The malondialdehyde dynamic changes, as evidenced by this study, show that changes in oxidative stress induced by the analyzed exercise, are more intense post-stress. 5) The results obtained in this study are consistent with the latest bibliographic data of the stress caused by exercise. 6) The two studied parameters could be considered important markers of the stress caused by intense and short duration exercise, for sedentary persons.
