Premenstrual syndrome (PMS) that occur during late luteal phase is a problem for many female athletes. Many studies reported that subjective condition is affected by PMS in female athletes. Moreover, female athletes with PMS have higher stress and/or anxiety levels during luteal phase compared with non-PMS athletes. However, the relationship between PMS and physical performance in female athletes are not clarified yet. The purpose of this study was to investigate the relationship between premenstrual syndrome (PMS) and jump performance in female track and field athletes. Sixteen participants who has natural basal body temperature pattern with the menstrual cycle (observed low-temperature and high-temperature phase), were participated in this study. PMS was assessed by ACOG’s premenstrual syndrome questionnaire. As physical performance, counter movement jump (CMJ) and rebound jump (RJ) were evaluated in low-temperature phase and high-temperature phase. The result of this study, no significant differences were observed in body composition and physical performance between low-temperature phase and high-temperature phase. However, compared with participants who had non-symptom, participants who had a breast tenderness of PMS showed larger decreases in jump height of CMJ (p = 0.038) and RJ index (p = 0.015) in high-temperature phase. Therefore, PMS may have a negative effect on physical performance during high-temperature phase in female athletes.

Arterial stiffness in endurance athletes is low, whereas arterial stiffness in strength athletes is high. The adaptation of the arterial stiffness may be different depending on the training type. On the other hand, there are mixed-trained athletes that can’t be classified as endurance- or strength- trained athletes. The aim of this study was to investigate the arterial stiffness among mixed-trained athletes. The total of 51 young male athletes (15 long-distance runners, 10 handball players and 26 kendo players) and 16 young healthy sedentary individuals (control group) participated in this study. Carotid-femoral pulse wave velocity (cfPWV), carotid-brachial PWV (cbPWV) and femoral-ankle PWV (faPWV), were measured as indices of central and peripheral (upper and lower limbs) arterial stiffness, respectively. cfPWV showed significantly lower in long-distance runners (high endurance capacity) and handball players (strength and high endurance capacities) compared with kendo players (strength and low endurance capacities) and control groups (P < 0.05 for both). cbPWV showed significantly lower in handball players and kendo players compared with the control group (P < 0.05 for both). There was no difference in faPWV among the groups. These data suggest that the competitive characteristics of athletes (i.e., endurance capacity or target muscle groups of sport) influence the adaptation of arterial stiffness. It can be speculated that endurance capacity in mixed-trained athletes can affect central arterial stiffness and similar to endurance trained athletes. In addition, the adaptation in upper limb arterial stiffness will be included in the training effects associated with the sports-specific target muscle groups, while lower limb arterial stiffness may not be unaffected by any type of exercise.
