Increasing Limit, 1 Repetition Max
Scientific Research as well as decades of empirical data have demonstrated a greater increase in Limit Strength when Hypertrophy (what is considered a mass phase) and Power Training are part of your Training Program.

The above is the "Abstract" (Cliff Notes) of Dr Michael Zourdos' dissertation on this.
Zourdos' research found a primary key to increasing Limit Strength is...
Conjugate Training
...training different types of Strength at the same time: Limit Strength, Hypertrophy and Power.
Doing so provideds a...
Synergistic Effect
Synergistic means the sum (total) is greater than its parts.
It is like adding 2 + 2 and getting 5. The total is larger than its parts.
Each Strength enhancing the other.
Empirical Data
The Westside Powerlifting Training Protocol has been around 36 years, since about 1982.
This method employs Conjugate Training; training Strength (Max Effort), Hypertrophy (Repetition Method) and Speed Training (actually it's Power Training).
One of the concerns with lifters in weight classes is gaining weight and having to move up a weight class. Thus, the avoidance of...
Hypertrophy Training
This method is used to muscle mass. However, that does not necessarily mean an increase in body weight.
A well written and preformed Hypertrophy Training Program enables lifter to increase muscle mass while minimizing body fat; the end result is relative no change in body weight.
Secondly, the prime root of weight gain or weight loss is caloric intake (Diet); not training.
Third, a minimal amount of Hypertrophy Training for extremely lean individual with concerns gaining weight and remaining in their present weight class is easily addressed by placing less emphasis on it; performing a minimal amount of Hypertrophy work.
One reason some Hypertrophy Training Sets need to be employed is as a means of increasing Strength is...
Muscle Recovery
One of the keys for increasing your training recover is to increase blood flow to the muscles after a training session.
The circulatory system delivers nutrients to the muscles for repair and eliminates "Metabolites", the garbage from training.
The most effective method for this is...
Active Recovery
This means performing light, easy exercise that flood the muscle tissue with blood.
The least productive method is...
Passive Recovery
This amount to doing nothing after your heavy training session, just sitting around watching TV, etc.
There are a variety of way to incorporate Hypertrophy Training into a program that enhances recovery without increasing body weight/muscle mass...
You'll get more progression if you do a long set at the end of a training session
"The present results demonstrated the effects of an additional set of low-intensity exercise immediately after a high-intensity, low-repetition exercise in gaining muscular strength and endurance, suggesting its usefulness in the strength protocol", ...
Performing a Hypertrophy Set at the end of your Limit Strength Training increases blood to the muscle involved (promoting recover).
However, the single Hypertrophy Set post Limit Strength Training only minimally affects an increase in body weight, if at all.
To reiterate, Diet is the prime factor for weight gain or loss.
Summary
A greater increase in Limit Strength is elicited when some Hypertrophy and Power Training are part of your program.
