“…The ankle has more laxness at ovulation compared to other periods of the menstrual cycle [15,16]. In another study on women during the menstrual cycle, changes in mechanical properties of the ankle muscles such as tone, stiffness, and elasticity were correlated to postural sway [11,17,18].…”

Greater Postural Sway and Tremor during Balance Tasks in Patients with Plantar Fasciitis Compared to Age-Matched Controls

Plantar fasciitis (PF) is a common condition found in men and women and can reoccur throughout life. PF is commonly diagnosed by prolonged foot pain lasting more than 3 months and a plantar fascia over 0.4 mm thick, as measured using ultrasound imaging. This study examined the ability to balance and the occurrence of muscle tremor during different balance tasks in patients with PF compared to their control counterparts. Fifty subjects (25 patients with PF and 25 control subjects) participated in this study. Subjective pain (measured with a visual analog scale (VAS)), pressure pain threshold (PPT), and postural sway and tremor during eight different balance tasks were measured. Postural sway was measured by a balance platform, while tremor was measured as the mechanical movement of the platform in the 8 Hz frequency range. Thickness of plantar fascia, subjective pain, and PPT were significantly greater in the PF group compared to the controls (p < 0.001). Postural sway and 8 Hz tremor were significantly greater in the PF group compared to the control group for all eight balance tasks (p < 0.01). These results indicate that the lack of plantar fascia elasticity is probably the cause of the reduced balance and increased muscle tremor.

“…They revealed that hamstring stiffness did not change across the menstrual cycle; however, hamstring extensibility increased in ovulation phase. Moreover, Sung and Kim (12) reported that muscle tone and stiffness of the vastus medialis and semitendinosus muscles were higher in ovulation phase compared to follicular and luteal phases; however, menstrual cycle did not affect the muscle tone and stiffness of the vastus lateralis and biceps femoris muscles.

“…The sample size calculation was performed using the SPSS Sample Power 3.0 software (IBM Corporation, Armonk, NY). It was estimated that at least 21 females had to be included in this study for 80% power with 5% type-1 error level to detect a minimum significant difference of 35 N • m for muscle stiffness among menstrual phases, when the average value of muscle stiffness in follicular phase is 242 N • m, with a standard deviation of 35 N • m (12).…”

“…Indeed, there are some attempt which investigated the effect of menstrual cycle on mechanical properties of muscle and/or tendon, but the results of these studies are contradicting. Some of these studies revealed a decrease in muscle stiffness and/ Menstrual cycle effect on muscle and tendon or elasticity in ovulation phase (11,12); however, the other reported no significant difference in muscle stiffness and/ or elasticity among the menstrual phases (13,14). Furthermore, there are limited study about menstrual cycle effect on tendon mechanical properties, and they used indirect methods to determine the differences in tendon mechanical properties (15,16).…”

Background. The evidences suggest that the risk of orthopaedic injury is the highest in the ovulation phase of the menstrual cycle. The change on mechanical properties of muscle and/or tendon related the higher estrogen concentration in the ovulation phase may be related to the highest risk of orthopaedic injury in ovulation phase. The purpose of the study was to investigate the menstrual cycle effect on the stiffness, elasticity and/or tone of the medial gastrocnemius muscle, Achilles and patellar tendons. Methods. The study was carried out in 30 healthy sedentary young females. The stiffness, elasticity and/or tone of the medial gastrocnemius muscle, Achilles and patellar tendons were measured using a MyotonPRO device. The stiffness, elasticity and/or tone of selected muscle and tendons were measured in the follicular, ovulatory, and luteal phases to determine the menstrual cycle variation. Results. There was no significant difference in stiffness, elasticity and tone of the Achilles tendon, patellar tendon and medial gastrocnemius muscle among phases (p > .05). Conclusions. The results suggest that the menstrual cycle do not affect the stiffness, elasticity and/or tone of the medial gastrocnemius muscle, Achilles and patellar tendons.

“…Muscle and tendon stiffness have been investigated in a number of studies to establish whether MC phase is a risk factor for soft tissue injuries; some studies concluded that stiffness is affected by MC phase [ 30 , 31 ]. A relationship has been considered between stiffness of lower limb muscles and tendons and performance in tests that require reactive hops or jumps, such as short sprints or multiple jump tests [ 32 , 33 ], as greater stiffness provides for better storage and use of elastic energy [ 32 ]; MC phase could also alter performance via changes in tissue stiffness.…”

The effect of the menstrual cycle on physical performance is being increasingly recognised as a key consideration for women’s sport and a critical field for further research. This narrative review explores the findings of studies investigating the effects of menstrual cycle phase on perceived and objectively measured performance in an athletic population. Studies examining perceived performance consistently report that female athletes identify their performance to be relatively worse during the early follicular and late luteal phases. Studies examining objective performance (using anaerobic, aerobic or strength-related tests) do not report clear, consistent effects of the impact of menstrual cycle phase on physical performance. Overall sport performance can be influenced by both perceived and physical factors. Hence, to optimise performance and management of eumenorrheic female athletes, there is a need for further research to quantify the impact of menstrual cycle phase on perceived and physical performance outcomes and to identify factors affecting variability in objective performance outcomes between studies.
