Summary

This study will be conducted to compare between the effect of nonlinear and linear periodized training on quality of life in females with hypothyroidism.

Detailed description

Worldwide, the incidence of individuals with thyroid dysfunction is increasing and represents approximately 30-40% of the patients seen in an endocrine clinic; thus, it is one of the leading endocrine disorders.The undiagnosed thyroid dysfunction especially subclinical and clinical hypothyroidism may increase cardiovascular risk factors. The prevalence of hypothyroidism depends on many factors, such as age, sex and geographical factors. It's also a diet related disorder and it's usually seen when the daily intake of iodine falls below 25μg. Hypothyroidism tends to affect women more often than men and can manifest at any age, typically observed between 40 and 70 years. No specific racial predilection has been identified in studies regarding this condition. regular exercise can improve quality of life in patients with subclinical hypothyroidism by increasing physical activity level/fitness and reducing the signs and symptoms of the disease. Exercise may therefore potentiate the effectiveness of levothyroxine and help hypothyroid individuals improve their quality of life. Periodization of resistance training or planned changes in training volume and intensity are used to maximize strength and fitness gains. The most common of periodized resistance training plans is linear also termed classic or strength/power periodization and nonlinear periodization. The biggest difference between these two types of training plans is with nonlinear periodization changes in training volume and intensity are made more frequently. The most common type of nonlinear periodization is daily nonlinear periodization where substantial changes in training intensity and volume are made from one training session to the next training session. So, this study will be conducted to compare between the effect of non linear and linear periodized resistance training on quality of life in females with hypothyroidism.

Conditions

• Hypothyroidism

Interventions

Type	Name	Description
OTHER	non linear periodization exercise	The non-linear periodized resistance training program follows a 12-week schedule with varying intensity levels across three training days per week. The intensity fluctuates between very light (VL), light (L), moderate (M), heavy (H), and very heavy (VH) workouts, distributed strategically throughout the week. Each training day implements different intensity levels, and an active rest day follows any workout session.
OTHER	linear periodization exercise	The linear periodization exercise program spans 12 weeks with systematically varied training parameters. During weeks 1-2, participants perform 3 sets of 10 repetitions, followed by 3 sets of 8 repetitions in weeks 3-4. The program progresses to 4 sets of 6 repetitions in weeks 5-6, then 3 sets of 6 repetitions during weeks 7-8. The final phases consist of 4 sets of 4 repetitions in weeks 9-10, concluding with 3 sets of 4 repetitions in weeks 11-12. Training loads advance through autoregulatory progression, where participants progress at their individual pace under supervision. While sets and repetitions remain fixed within each phase, load progression is determined by performance in the final set of each exercise, ensuring safe and effective advancement.
DRUG	medical treatment	The medical treatment will be received for 12 weeks.
