Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The hypothesis suggested that moderate volume training would yield optimal muscle development, considering the potential non-linear dose-response relationship where excessive training might be detrimental. Measurements included body composition, muscle thickness, and peak power through a force platform during vertical jumps.
Data analysis focused on changes in muscle thickness, strength, and body composition, with statistical significance set at p \< 0.05. The study aimed to provide insights into how different training volumes affect physiological adaptations in untrained women, potentially guiding fitness regimen optimizations for similar populations.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Participants were randomly assigned to one of three groups: low-volume training (LVT) with three sessions weekly, moderate-volume training (MVT) with four sessions weekly, and high-volume training (HVT) with five sessions weekly. Each session comprised 12 exercises. Split split-strength training method was applied. After participants' 1RM maximums were determined, training loads were calculated separately for each participant. All workouts were conducted by certified trainers to ensure they were performed in the correct training format. Each training session lasted approximately 60 minutes. The weekly training loads of all participants were increased by 5%. In the LVT group, 3 sets of 8-12 repetitions of: between sets interval: 120 seconds (3 days/wk), in the MVT group, 3 sets of 8-12 repetitions of: between sets interval: 120 seconds (4 days/wk), in the HVT group, 3 sets of 8-12 repetitions of: between sets interval: 120 seconds exercises (5 days/wk) were performed.
Results and data analysis involved anthropometric measurements, muscle thickness via ultrasound, and peak power from the vertical jump test. Statistical significance was set at p \< 0.05, and effect sizes were calculated with Partial Eta Squared values.

low volume (LVT) resistance training
3 sessions of 12 exercises per week for 8 weeks . Split-strength training method will be applied. After participants' 1RM maximums were determined, training loads were calculated separately for each participant. All workouts will be conducted by certified trainers to ensure they are performed in the correct training format. Each training session lasted approximately 60 minutes. The weekly training loads of all participants will be increased by 5%. In the MVT group, 3 sets of 8-12 repetitions: between sets intervals: of 120 seconds will be performed.
Resistance exercise-LVT
