NCT05667233 | Completed

• 1 other identifier: 2022-6399
• Study Type: interventional
• Target: 13
• Locations: 1 country

Brief Summary

This study aims to investigate if a less physically and psychologically taxing approach to resistance training can generate equal or greater outcomes when compared to a more physically and psychologically taxing approach.

Conditions

Hypertrophy; Body Weight Changes; Muscle Size

Keywords

Exercise; Resistance Training

Outcome Measures

Primary Outcomes (1)

• Segment girth (cm)

  Upper arm (biceps) circumference, mid-thigh (quadriceps) circumference, waist (abdomen) circumference

  8-weeks

Secondary Outcomes (2)

• Body composition (kg)

  8-weeks

• Body Fat Percentage

  8-weeks

Study Arms (2)

Train to failure

ACTIVE COMPARATOR

Training regime will be highly uncomfortable since it will be both physically and psychologically challenging to push to momentary muscular fatigue (MMF; i.e., failure).

Other: Resistance Training Program

Train to non-failure

ACTIVE COMPARATOR

Training regime will be moderately uncomfortable as participants will be training at a close proximity to failure (4-0 repetitions in reserve; i.e., non-failure).

Other: Resistance Training Program

Interventions

Resistance Training Program OTHER

Participants will undergo a high exertion machine-based resistance training protocol.

Train to failure; Train to non-failure

Eligibility Criteria

• Age: 18 Years+
• Sex: male
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• biological male
• age 18 years or older
• enrolled at Dalhousie university
• minimum 3-months of consistent (at least 2x/week) resistance training experience

You may not qualify if:

• body fat percentage 25% or greater (obese)
• use of performance enhancing drugs that aim to increase rate of muscle growth (i.e., androgenic steroids, anabolic steroids, selective androgen receptive modulators, growth hormone).

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Purpose: BASIC SCIENCE
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Instructor, Kinesiology

Model Details: Participants will be randomly assigned to one of two parallel groups (train to failure OR train to non-failure) and stratified according to their recent training experience (beginner \[3-9 months experience\], intermediate \[9-18 months experience\], advanced \[\>18 months experience\]).
