Menopause01:28

Menopause

Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Hormonal Control of the Ovarian Cycle

The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle.  At puberty, GnRH secretion increases in both frequency and...
Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

Area of Science:

  • Gerontology
  • Exercise Physiology
  • Rehabilitation Science

Background:

  • Sedentary lifestyles in middle-aged women (40-60 years) are associated with age-related decline in balance and physical function.
  • Maintaining physical activity and balance is crucial for preventing falls and promoting healthy aging.

Purpose of the Study:

  • To assess the effectiveness and long-term benefits of a specific balance-strategy training program.
  • To determine if the program encourages a more active lifestyle in sedentary women aged 40-60.

Main Methods:

  • A randomized controlled trial involving 50 healthy women aged 40-60.
  • Participants were assigned to either an intervention (12 weeks, twice-weekly training) or control group.
  • Assessments included demographics, activity level, balance, somatosensory function, ankle flexibility, and leg muscle strength pre-, post-intervention, and at 9-month follow-up.

Main Results:

  • The intervention group showed significant improvements in balance, ankle flexibility, and muscle strength compared to the control group immediately post-intervention.
  • These improvements were maintained at 9-month follow-up, with additional latent improvements in somatosensory measures.
  • The intervention group demonstrated a significant adoption of a more active lifestyle.

Conclusions:

  • The physiotherapist-designed balance program effectively preserves or reverses age-related balance decline in middle-aged women.
  • The program promotes sustained improvements in physical function and encourages a transition to a more active lifestyle.
