Higher- Versus Lower-Intensity Strength-Training Taper: Effects on Neuromuscular Performance
International Journal of Sports Physiology and Performance
|September 12, 2018
Summary
A strength-training taper with reduced volume positively impacts power. A higher-intensity taper may yield greater improvements in strength and power compared to a lower-intensity taper.
Area of Science:
- Sports Science
- Exercise Physiology
- Strength and Conditioning
Background:
- Periodization is crucial for optimizing athletic performance.
- Strength-training tapers involve planned reductions in training volume and/or intensity before competition.
- The optimal intensity and volume manipulation during a taper remains an area of investigation.
Purpose of the Study:
- To examine the effects of strength-training tapers with identical volume reductions but varying intensities on neuromuscular performance.
- To compare the efficacy of higher-intensity versus lower-intensity tapers in enhancing power and strength.
Main Methods:
- Eleven strength-trained males participated in a crossover study involving two 4-week training blocks followed by a taper week.
- Tapers involved a ~70% volume reduction with either increased (5.9%) or decreased (-8.5%) intensity.
- Neuromuscular performance, including countermovement jump (CMJ) and isometric strength, was assessed pre- and post-training and post-taper.
Main Results:
- Countermovement jump (CMJ) height and flight time:contraction time significantly increased over the study period.
- Isometric midthigh pull relative peak force also showed significant improvements over time.
- While no significant differences were found between taper types, the higher-intensity taper showed a trend towards greater improvements in strength and power metrics.
Conclusions:
- Strength-training tapers with reduced volume positively influence power output.
- A higher-intensity taper may offer a slight advantage in improving strength and power compared to a lower-intensity taper.
- Further research is warranted to elucidate the precise mechanisms and optimal parameters for strength-training tapers.

01:19Ionic Strength: Effects on Chemical Equilibria
2.7K
The addition of an inert ionic compound increases the solubility of a sparingly soluble salt. For example, adding potassium nitrate to a saturated solution of calcium sulfate significantly enhances the solubility of calcium sulfate. Le Châtelier's principle cannot predict this shift in the equilibrium. Instead, this could be explained in terms of changes in the effective concentration of the ions in solution in the presence of added inert salt.

Binary Acids and Bases
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...

Strength tests for cement are not performed directly on neat cement paste due to difficulty in obtaining consistent, reliable specimens. Instead, cement is typically tested in the form of cement-sand mortar.
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...

01:30Relation Between Tensile Strength and Compressive Strength of Concrete
685
Concrete is a fundamental building material, and understanding its strengths is crucial for construction projects. The relationship between its tensile and compressive strengths is intricate, showing that while these strengths are related, they do not increase at the same rate. Tensile strength's growth is slower and is affected by various factors such as the methods used for testing, the size and shape of the specimen, the texture of the aggregate used, and the moisture content of the...

00:58Sound Intensity
4.8K
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the...
