简要总结
Energy availability (EA) refers to the balance between daily energy intake and exercise energy expenditure. Athletically inadequate EA is defined as low energy availability (LEA). Energy deficits occur throughout life, from young athletes with a relative lack of energy in sports or the female athlete triad to older adults struggling with weight loss. Acute and/or chronic LEA can cause negative athletic and health outcomes in athletes.
It is known that LEA, as an energy saving mechanism, suppresses the reproductive system and causes disruption of the menstrual cycle, as well as causing many interrelated endocrine-related physiological consequences by changing other hormonal pathways. Menstrual dysfunction due to LEA causes various risks as it can disrupt the EC during training and competition. Therefore, low EA may contribute to poor sports performance due to detrimental endocrine effects.
Various parameters such as body mass and nutritional intake affect the performance of athletes, and LEA is frequently reported among athletes with intense training programs. LEA combined with high training volumes; It can cause negative consequences such as impaired protein synthesis/degradation rate, impaired hormonal and training response, increased risk of fatigue, and these can lead to decreased performance. Resting metabolic rate, which indicates the energy expended for basic body functions, is considered a potential objective indicator of energy availability.
Regulation of dietary energy intake in the management of LEA in athletes covers a wide area in the literature. However, LEA is caused not only by a deficiency in energy intake but also by an excess in energy expenditure. In the light of this information, the aim of the study is to examine the acute period effects of the training program in which exercise energy expenditure is reduced in terms of energy availability and athletic performance.
详细描述
Voluntary participants who have been diagnosed with energy deficiency will be included in the study. Signed voluntary consent will be obtained from participants. Participants will be divided into two groups. Study groups will be as follows: a) Modified Training, b) Routine Training.

研究组 & 干预措施
Modified Training Group
It is a training program that will be carried out under the supervision of a physiotherapist. There will be 3-minute breaks between sets. A training program will be applied to the athletes based on revising the training program they use in their routine with eccentric contractions.
干预措施: Modified Training Programme (Other)
Routine Training Group
The training program that the athlete uses in her normal routine will be implemented under the supervision of a physiotherapist.
干预措施: Routine Training Programme (Other)
结局指标
主要结局
Running Performance Analysis - Economy of the Running
时间窗: 3 times for 2 weeks
Performance analysis will be performed on a 10-meter platform with DigitSole in order to evaluate the economy of the athlete's running activity.
Energy Availability
时间窗: change from baseline pain at 2 weeks
The underlying etiology of Relative Energy Deficiency in Sports is low energy availability, which occurs when dietary energy intake is inadequate for an athlete's physical activity level. "Energy availability = Energy Intake (kcal) - Exercise Energy Expenditure (kcal/fat - free mass \[fat free mass; kg\])"
Running Performance Analysis - Biomechanics
时间窗: 3 times for 2 weeks
Performance analysis will be performed on a 10-meter platform with DigitSole in order to evaluate the biomechanics.
Relative Energy Deficiency in Sports Clinical Assessment Tool (RED-S CAT)
时间窗: 3 times for 2 weeks
It is a clinical assessment tool used to evaluate athletes or active individuals with suspected low energy availability and serves as a guide for clinicians and coaches in return-to-play decisions.
Running Performance Analysis - Running Speed
时间窗: 3 times for 2 weeks
Performance analysis will be performed on a 10-meter platform with DigitSole in order to evaluate the running speed.
次要结局
- thyroid stimulating Hormone Levels(3 times for 2 weeks)
- Adrenocorticotropic Hormone Levels(3 times for 2 weeks)
- Gonadotropin-Releasing Hormone Levels(3 times for 2 weeks)
- Follicle-stimulating Hormone Levels(3 times for 2 weeks)
- Luteinizing Hormone Levels(3 times for 2 weeks)
