Active clinical trials for "Female Athlete Triad Syndrome"

Energy Deficit Syndrome (RED-S) is the impairment of physiological functioning caused by relative energy deficiency and includes impaired metabolic rate, menstrual, endocrine, hematological, immunological, gastrointestinal, bone, psychological, developmental and cardiovascular function. Eighty-seven percent of athletes show at least one symptom related to RED-S, with a higher prevalence in women. Treatment of RED-S preferably involves a multidisciplinary team of health professionals to address the complex interaction of nutrition, training, body image and performance. The main objective is to prevent energy deficit syndrome in female athletes in the province of Alicante through different training and diet protocols using a virtual platform. A 12-week single-blind randomized clinical trial with an intervention period and a control period (RCT) is proposed. The sports federations of the most representative practices in the province of Alicante will be selected by randomized sampling. The female athletes will be randomly divided into 4 groups (control group; control group with free use of the virtual platform; intervention group with Mediterranean diet and physical exercise planning; intervention group with red fruits and physical exercise planning).

The aim of this study to determine the effect of soy phytoestrogens and acupuncture on osteoporosis in female athlete triad at adolescence age. It is hypothesized that: - There will be no statistical significant difference between the effects of soy phytoestrogens and acupuncture on osteoporosis in female athlete triad at adolescence age. RESEARCH QUESTION: Do soy phytoestrogens and acupuncture have an effect on bone mineral density in female athlete triad at adolescence age?

Finding alternatives to improve variables such as strength and anaerobic resistance is a subject of highly studied clinical intervention. The use of vascular occlusion associated with physical exercise has shown efficacy in improving these aspects. The objective is to analyze the effectiveness of upper limb training with vascular occlusion (Kaatsu training) for the improvement of isometric strength and anaerobic capacity in women aged 18 to 38 years. Study design. Randomized, prospective, single-blind, follow-up clinical study. The selected sample will be randomized into two groups: experimental and control. The intervention will consist of ergonomic exercises with and without vascular occlusion. Isometric strength will be assessed with a manual dynamometer, anaerobic capacity and peak power (anaerobic alactic system) and average power (anaerobic lactic system) with the wingate test, and subjective perception of effort with the Borg scale. The intervention will last 4 weeks, with 3 weekly sessions of 10 minutes each. A descriptive statistical analysis will be carried out among the dependent and independent variables of both groups. With the Kolmogórov distribution normality test and with the Anova and t-student tests for analysis of repeated measures. Expected results. The investigators intend to observe improvement of isometric biceps and triceps strength and the anaerobic capacity of the group treated with vascular occlusion.

The present study will be designed to investigate the effect of acupuncture and diet modification using soy products on amenorrhea in female athlete triad. For this purpose this study will be carried out on sixty female athletes participating gymnastics. They will be recruited from Sports Medicine specialized center in Nasr City, their ages will range from 17 to 25 years old and their BMI will be < 20 Kg/m2 .

Given the cost of treating eating disorders and the substantial morbidity and mortality associated with these disorders, prevention of eating disorders has considerable public health significance. Female athletes represent an important population for prevention due to their risk for the Female Athlete Triad, which includes inadequate energy intake, irregular or cessation of menses, and osteoporosis. The proposed randomized controlled trial will provide important information regarding the efficacy, acceptability, and feasibility of implementing a brief eating disorder prevention and healthy living program within an existing social system of female athletes.

Osteoporosis is worldwide health epidemic categorized by poor bone health, primarily diagnosed by low bone mineral density, and costs healthcare systems billions every year. Athletes and exercising people who expend large amounts of energy in physical activity, or restrict diet in order to lose weight, are at risk of low energy availability. This is when an individual fails to match their exercise energy demand with a appropriate dietary intake in order to maintain optimal physiological function; which can lead to low bone mineral density, osteoporosis both early and later in life and an increased risk of injury. Runners are particularly susceptible to stress fracture in response to low energy availability due to repetitive ground impact. Research shows that as little as five days low energy availability significantly reduces bone formation, and significantly increases bone resorption, in physically active women. The ideal solution is to restore energy availability; however, this is often very difficult during periods of intense training and conflicts with the goal of weight loss. Therefore, there is a need to develop an alternative tool to protect bone health. It is critical that any exercise intervention does not further reduce energy availability as previous research shows that this accelerates bone loss rather than prevents it. Low repetition high impact jumping exercise is highly beneficial to bone health and has been shown to improve bone structure when used as a long-term intervention in energy replete states. It takes very little time to complete and uses a very small amount of energy. However, no study to date has examined the effects of such an intervention during low energy availability. The current study will investigate whether low repetition high impact jumping prevents or reduces the reduction in bone formation and the increase in bone resorption experienced during five days of low energy availability and findings will have implications on athletic and recreational training recommendations in order to protect bone health.

Trial objectives and purpose: The primary aim is to study the effects of moderately increased testosterone concentration on aerobic performance (endurance running time to exhaustion), and secondary aims to investigate the effects on submaximal work on treadmill, anaerobic capacity, muscle strength, body composition, behaviour and well-being, blood parameters, steroid hormone profile, gynecological parameters and skeletal muscle parameters in young healthy women in a double-blind, randomized, placebo-controlled trial. Treatment: Ten weeks of transdermal treatment with testosterone cream 10 mg daily or placebo cream in a randomized design (1:1). Primary outcome: Aerobic performance (running time to exhaustion on treadmill) Secondary outcomes: Submaximal work on treadmill (oxygen uptake, ventilation, heart rate, blood lactate and subjective rate of exhaustion) Anaerobic performance (Wingate test) Muscle strength (Cybex apparatus, force transducer, counter movement jump) Body composition (Dual X-ray Absorptiometry: muscle mass, fat mass, bone mass) Behaviour and well-being (Quality of life, Profile of mood state, Confidence Questionnaire, Aggression Questionnaire) Blood parameters (hemoglobin, hematocrit, reticulocytes, ferritin, CRP) Steroid hormone profile in blood and urine Gynecological evaluation (ovarian and endometrial variables on ultrasound) Skeletal muscle morphology, metabolic enzymes and muscle protein synthesis Study population: Fifty healthy menstruating women will be included in the study and randomized to treatment with testosterone or placebo. Inclusion criteria: 18-35 yrs of age; body mass index (BMI) 19-25; non-smoking; a moderate to high self-reported level of recreational physical activity; not taking hormonal contraception and willing to use highly efficient non-hormonal contraception during the study (intrauterine device, bilateral tubal occlusion, vasectomised partner, same-sex partner, or sexual abstinence); accepting to not participate in any sports competitive event during the study period plus one month. Exclusion criteria: the presence of cardiovascular, liver, biliary or renal disease; hyperlipidemia; uncontrolled high blood pressure; endocrinological disorder; oligomenorrhea (menstrual intervals of more than 6 weeks) or amenorrhea (no menstruation for at least 3 months); pregnancy; a history of thromboembolic disorder; any malignancy; and intake of hormonal contraception the last two months prior to the study.

The purpose of this project is to study the impact of energy availability (EA) on female endurance athletes and the adaptive consequences of insufficient EA with a special reference to the impact on energy metabolism, reproductive-, vascular- and bone health as well as exercise capacity, neuromuscular performance, ability to recover from intense exercise and the genetic interaction. Specific aims: To investigate the effects of EA on energy metabolism To investigate the effects of EA on reproductive, vascular- and bone health, and endocrine functions To investigate the effects of EA on exercise capacity To investigate the effects of EA on neuromuscular performance To investigate the effects of EA on recovery after exercise To identify potential dietary factors influencing EA, exercise capacity and neuromuscular performance To identify potential exercise factors influencing EA, exercise capacity and neuromuscular performance To identify potential psychological, behavoural and motivational aspects associated with insufficient EA The investigators hypothesize that female athletes with insufficient energy availability have attenuated energy metabolism, reduced BMD, impaired endothelial function and decreased ability to recover between exercise bouts compared to matched controls with sufficient energy and nutrient intake. The investigators also hypothesize that EA influences exercise capacity and neuromuscular performance.
