Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn the effects of stable and unstable resistance training on physical fitness, kidney function and blood lipid tests in healthy young male volunteers. The main questions it aims to answer are:

* Do both stable and unstable resistance training increase the level of urinary protein clearance greater than the control group?
* What is the difference in improvement of lipid profiles among the groups?
* Does unstable resistance training mode rise muscular endurance greater than stable resistance training?

Researchers will compare stable and unstable resistance training to see if there are differences on physical fitness measures, blood lipid and urinary protein tests.

Participants, in their respective group will receive ten weeks of:

* Stable resistance training
* Unstable resistance training or
* No exercise training intervention

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study included volunteer male untrained students living at Kotebe University of Education. Priori statistical power analysis (G\*Power version 3.1.9.2, Stuttgart, Germany) was used to estimate the sample size. Based on earlier research, a moderate to high effect size (0.295) was assumed, and considering a dropout probability of 10%, a sample of 54 participants was enough to meet adequate statistical power. All participants provided written informed consent to participate in this study. The training protocol will include ten resistance exercises for each intervention, performed three times a week for 10 weeks. Each session lasts 60 minutes, including a 10 to 15-minute warm-up, a 40-minute main exercise targeting core, upper, and lower limb muscles, and a 5 to 10-minute cool-down and stretching. The protocol will adhere to basic training principles like overload, progression, and specificity. The training will take place in the university gymnasium. The study will be conducted in accordance with local legislation and institutional requirements. It will be strictly governed by the ethical principles of the Declaration of Helsinki.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

This study employs a randomized pre-post-test experimental design with three groups. It involves a stable and unstable resistance training intervention for two training groups and a control group without training intervention but, advised to continue their regular daily routine.
Primary Study Purpose

PREVENTION

Blinding Strategy

NONE

Participants were randomly assigned to a stable, unstable, and control group by computer software. All participants and the researcher know the assignment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Unstable resistance training group

Receiving total body resistance exercise (TRX) training intervention

Group Type EXPERIMENTAL

resistance training

Intervention Type OTHER

TRX based resistance training for the upper, lower and abdominal region muscles

Control group

no any structured exercise training intervention

Group Type NO_INTERVENTION

No interventions assigned to this group

stable resistance training group

receiving traditional resistance training intervention

Group Type EXPERIMENTAL

resistance training

Intervention Type OTHER

stable resistance training is represented by traditional resistance training using equipment like medicine ball, resistance machine and own body mass
