Aktiver Komparator: Standard-frequency resistance training
|
Full-body resistance training consisting of 10 sets per week for all major muscle groups with progressive overload in a gym-based setting.
Training at an exercise frequency of two sessions per week (around 45-60 minutes per session).
|
|
Experimental: High-frequency resistance training
|
Full-body resistance training consisting of 10 sets per week for all major muscle groups with progressive overload in a gym-based setting.
Training at an exercise frequency of 10 brief sessions per week (around 8-12 minutes per session).

Change in Total Body Muscle Size Measured as Cross-sectional Area using Muscle Ultrasound Imaging
Zeitfenster: From enrolment (Week 1) to the end of the exercise training phase (Week 12)
|
Muscle ultrasound imaging will be conducted on one randomly selected side of the body (left or right) for each participant.
Scans will be analyzed to determine the cross-sectional area of the following seven muscles: rectus femoris, vastus lateralis, biceps brachii, pectoralis major, latissimus dorsi, triceps brachii, and hamstring group (semitendinosus, semimembranosus, and long head of biceps femoris).

Change in Muscle Strength Measured as the One-Repetition Maximum of Back Squat and Bench Press
Zeitfenster: From enrolment (Week 1) to the end of the exercise training phase (Week 12)
|
One-repetition maximums will be measured using a Quantum Synchro Smith Machine.
|
From enrolment (Week 1) to the end of the exercise training phase (Week 12)
|
|
Change in Skeletal Muscle Power Measured at Various Relative Loads for Back Squat and Bench Press
Zeitfenster: From enrolment (Week 1) to the end of the exercise training phase (Week 12)
|
At enrolment (Week 1), power will be measured using a Quantum Synchro Smith Machine at 40%, 50%, 60%, 70%, and 80% of the participant's initial one-repetition maximum (1RM) for back squat and bench press.
At the end of the exercise training phase (Week 12), if a participant's 1RM has increased by less than 25%, power will be measured at the same relative loads.
If a participant's 1RM has increased by 25-49%, power will be measured at 50%, 60%, 70%, 80%, and 90% of the participant's initial 1RM (in this case, 90% of the participant's initial 1RM would not exceed 80% of the participant's post-training 1RM).
If a participant's 1RM has increased by 50% or greater, power will be measured at 60%, 70%, 80%, 90%, and 100% of the participant's initial 1RM (in this case, 100% of the participant's initial 1RM would not exceed 80% of the participant's post-training 1RM).

From enrolment (Week 1) to the end of the exercise training phase (Week 12)

Participant Satisfaction with the Exercise Program
Zeitfenster: At the end of the exercise training phase (Week 12)
|
Participant satisfaction with the exercise program will be measured using a modified Intrinsic Motivation Inventory (subscales of "Interest/Enjoyment", "Percieved Competence", "Effort/Importance", and "Value/Usefullness").

At the end of the exercise training phase (Week 12)
