Periodization for Massive Strength Gains
In order to create the perfect resistance training program for their athletes, coaches must master the ability to control all variables of training over time in order to maximize physiological responses - this is a concept known as periodization (3, 6, 7, 8, 9, 10, 19, 21, 24, 25, 26).
Periodization was first established in Russia, after the conclusion of the 1956 Olympic games (7, 21). Though simple in its principle and aim, periodization is frequently misunderstood due to the hyper-specific research that surrounds it (3, 4, 7, 8, 10, 15, 21, 23, 25). Over the last five decades, researchers have produced a multitude of studies that look at specific variables of periodization, which this paper will later examine, but many of them prove to be inconclusive due to uncontrollable factors outside of training (3, 4, 7, 8, 13, 14, 19, 21). These uncontrollable factors make it difficult to be absolute in any conclusions surrounding the topic of periodization, though there are a number of considerations that make periodization very valuable (25).
Periodization is of paramount importance when creating resistance training plans due to its role in the manipulation and subsequent control of variables over time (3, 6, 7, 8, 9, 10, 19, 21, 24, 25, 26). Without control of variables, resistance training becomes an aimless and non goal-oriented task (25, 43). In comparison with non-periodized resistance programs, periodized plans prove to be significantly more effective in strength gained, lean mass gained, and percent body fat lost (1, 5, 6, 11, 15, 25). Periodization will likely remain a topic of controversy for a long time to come, as coaches continue to seek the most effective combination and manipulation of training variables at their disposal (23)
New horizons for the methodology and physiology of training periodization: Block Periodization: New horizon or a false dawn?
It would appear premature to herald block periodization as a ‘new horizon’ in training planning, partly because of a fundamental lack of supporting evidence and clearly delineated rationale, and partly because contradictory evidence exists questioning its universal efficacy in elite contexts. What block periodization does positively contribute to current planning methodologies is a more formal description of a particular planning tactic that may be advantageously added to the elite coaches menu of potential planning options. Therefore, while blocked-training schemes may be useful ploys in specific training contexts, the claim that this framework represents a new departure in training planning may be somewhat overly enthusiastic. Hence, perhaps a more appropriate description of block periodization is ‘new variation’, rather than a ‘new horizon’, in sports training planning
Periodization of Robert Mugabe’s Land Policy In Zimbabwe
This project explores how Zimbabwean leader Robert Mugabe handled the culturally vital land issue. Research was conducted using scholarly sources including books and academic articles related to Zimbabwe, Rhodesia, land policy, economic analysis, and governmental legal policies. Information collected was divided into four historical periods based on the major land policies shaping government action. This periodization helps simplify the land issue by contextualizing the vast information surrounding Zimbabwean history. Analysis of government actions during these periods shows the land issue consistently being tied to other goals. The essay argues that Mugabe has used the call of land reform to fulfill personal political objectives and consolidate power. In the process, this project explores the modern history of Zimbabwe and the reasons land has become central to African identity
Noncommutative de Leeuw theorems
Let H be a subgroup of some locally compact group G. Assume H is approximable
by discrete subgroups and G admits neighborhood bases which are
"almost-invariant" under conjugation by finite subsets of H. Let be a bounded continuous symbol giving rise to an Lp-bounded Fourier
multiplier (not necessarily cb-bounded) on the group von Neumann algebra of G
for some . Then, yields an Lp-bounded Fourier
multiplier on the group von Neumann algebra of H provided the modular function
coincides with over H. This is a noncommutative form of
de Leeuw's restriction theorem for a large class of pairs (G,H), our
assumptions on H are quite natural and recover the classical result. The main
difference with de Leeuw's original proof is that we replace dilations of
gaussians by other approximations of the identity for which certain new
estimates on almost multiplicative maps are crucial. Compactification via
lattice approximation and periodization theorems are also investigated
Quantization of pseudo-differential operators on the torus
Pseudo-differential and Fourier series operators on the n-torus are analyzed
by using global representations by Fourier series instead of local
representations in coordinate charts. Toroidal symbols are investigated and the
correspondence between toroidal and Euclidean symbols of pseudo-differential
operators is established. Periodization of operators and hyperbolic partial
differential equations is discussed. Fourier series operators, which are
analogues of Fourier integral operators on the torus, are introduced, and
formulae for their compositions with pseudo-differential operators are derived.
It is shown that pseudo-differential and Fourier series operators are bounded
on under certain conditions on their phases and amplitudes.Comment: 36 page
Effects of a Tapering Period on Physical Condition in Soccer Players
The aim of this research was to analyze the effects of a 2-week step tapering period on lower-limb muscle power, change of direction (COD) and acceleration capacities, and on the stress-recovery state in an amateur soccer team. Twenty-two male players were included in the study. After a 6-week progressive training, the sample was divided into experimental group (EG) (n = 11), which did a 2-week period of taper in which training volume was 50% reduced (intensity was kept high) and control group (CG) (n = 11), which kept on with the training. Muscle power (countermovement jump test), acceleration (10-m sprint test), COD (Illinois test), and stress and recovery perceptions (RESTQ questionnaire) were evaluated before training, at the end of it (pretapering, PRE-TP) and after the tapering period (posttapering, POST-TP). After the taper, the EG in comparison with the CG showed significantly improved power (1,029.71 ± 108.51 W·kg−1 vs. 1,084.21 ± 110.87 W·kg−1; p ≤ 0.01), acceleration (1.72 ± 0.09 seconds vs. 1.67 ± 0.07 seconds; p ≤ 0.05), and lower stress levels (1.9 ± 0.5 vs. 1.6 ± 0.5; p ≤ 0.01) (PRE-TP vs. POST-TP, respectively). Change of direction did not show significant changes. In conclusion, a 2-week step tapering program was found to be an effective periodization strategy to increase muscle power and acceleration, and to reduce stress perception in soccer amateur players
