BackgroundPeriodization is a logical method of organizing training into sequential phases and cyclical time periods in order to increase the potential for achieving specific performance goals while minimizing the potential for overtraining. Periodized resistance training plans are proposed to be superior to non-periodized training plans for enhancing maximal strength.ObjectiveThe primary aim of this study was to examine the previous literature comparing periodized resistance training plans to… 

Comment on: “Comparison of Periodized and Non-Periodized Resistance Training on Maximal Strength: A Meta-Analysis”

We read with interest the recent article published by Williams et al. [1], Comparison of Periodized and Non-Periodized Resistance Training on Maximal Strength: A MetaAnalysis, in which the authors

Effects of Periodization on Strength and Muscle Hypertrophy in Volume-Equated Resistance Training Programs: A Systematic Review and Meta-analysis

The results suggest that when volume is equated between conditions, periodized resistance training has a greater effect on 1RM strength compared to NP resistance training, and the effects of periodization on maximal strength may instead be related to the neurophysiological adaptations accompanying resistance training.

Periodization and Block Periodization in Sports: Emphasis on Strength-Power Training-A Provocative and Challenging Narrative.

Evidence indicates that a periodized training process coupled with appropriate programming can produce superior athletic enhancement compared with nonperiodized process.

Periodized Resistance Training for Enhancing Skeletal Muscle Hypertrophy and Strength: A Mini-Review

Both the linear model and the undulate model are effective for enhancing strength, although a greater benefit might be achieved through the undulating model, although this conclusion can only be generalized to untrained populations.

Periodization models in the research of the muscle strength in athletes, theoretical-methodological reductions or non-critical positivism in sport-scientific periodics

Periodization is a theoretical and practical construct of sports training that relates to the programming of training activities in mutually dependent periods of time in order to induce specific

Non-periodized and Daily Undulating Periodized Resistance Training on Blood Pressure of Older Women

It is indicated that a 22-week NP resistance training program causes beneficial effects on hemodynamic parameters of older women, since both training modes seem to have a cardio protective effect.

Different Patterns in Muscular Strength and Hypertrophy Adaptations in Untrained Individuals Undergoing Non-Periodized and Periodized Strength Regimens.

The findings suggest that in the latter half of the study (i.e. after the initial 6 weeks), the periodized regimens elicited greater rates of muscular adaptations compared to NP, and strength coaches and practitioners should be aware that periodize regimens might be advantageous at latter stages of training even for untrained individuals.

The Effect of Block Versus Daily Undulating Periodization on Strength and Performance in Adolescent Football Players.

Resistance training was effective to increase muscle mass, strength, power, and performance in adolescent athletes, with no difference between groups.

Non-Linear Resistance Training Program Induced Power and Strength but Not Linear Sprint Velocity and Agility Gains in Young Soccer Players

The data suggest that non-linear RT should be inserted into the routine of young soccer athletes for improving strength and power without impairing speed and agility.



Early adaptations to six weeks of non-periodized and periodized strength training regimens in recreational males.

Muscle hypertrophy occurs within six weeks in recreationally active men regardless the ST training regimen employed, and when the total volume is similar, training at greater intensities will demonstrate superior gains in the 1RM performance.

Comparison Between Linear and Daily Undulating Periodized Resistance Training to Increase Strength

Undulating periodized strength training induced higher increases in maximal strength than the linear model in strength-trained men, and daily intensity and volume variations were more effective than weekly variations.

Effects of Linear vs. Daily Undulatory Periodized Resistance Training on Maximal and Submaximal Strength Gains

Although there was no statistically significant difference between periodization models, DUP promoted superior ES gains in muscular maximal and submaximal strength.

The Effects of Periodization Versus Progressive Resistance Exercise on Upper and Lower Body Strength in Women

Volume of work performed was more powerful in determining strength than was the manipulation of repetitions, sets, or periods of active rest in the periodization and progressive resistance exercise groups.

A Comparison of Linear and Daily Undulating Periodized Programs with Equated Volume and Intensity for Strength

Making program alterations on a daily basis was more effective in eliciting strength gains than doing so every 4 weeks, according to analysis of variance with repeated measures.

Nonlinear Periodization Maximizes Strength Gains in Split Resistance Training Routines

The data suggest that NLP was more effective in increasing both upper- and lower-body strength for trained subjects using split routines than NP, LP, and NLP.

Influence of Resistance Training Volume and Periodization on Physiological and Performance Adaptations in Collegiate Women Tennis Players

The data demonstrate that sport-specific resistance training using a periodized multiple-set training method is superior to low-volume single-set resistance exercise protocols in the development of physical abilities in competitive, collegiate women tennis players.

A Meta-Analysis of Periodized versus Nonperiodized Strength and Power Training Programs

It is concluded that PER training is more effective than Non-PER training for men and women, individuals of varying training backgrounds, and for all age groups.


Results indicate that no separation based on periodization model is seen in early-phase training in training of recreationally trained college-aged volunteers.

Systematic Review and Meta-analysis of Linear and Undulating Periodized Resistance Training Programs on Muscular Strength

The results suggest that novelty or training variety are important for stimulating further strength development, and there were no differences in the effectiveness of linear vs. undulating periodization on upper-body or lower-body strength.
