Drive-Reduction Theory: Push Theory of Motivation01:27

Drive-Reduction Theory: Push Theory of Motivation

1.2K
Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or...

Hand hygiene

5.7K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Muscles of the Forearm that Move the Hand and Fingers

2.5K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Buffer Effectiveness02:19

Buffer Effectiveness

55.0K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...

Framing Effects03:26

Framing Effects

7.9K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Summary

Hand width significantly impacts upper-body force development during plyometric push-ups, though power output remains similar. This finding is crucial for accurate performance assessments in strength and conditioning.

Area of Science:

  • Sports Science
  • Biomechanics
  • Exercise Physiology

Background:

  • Plyometric push-ups are a common exercise for assessing upper-body power.
  • The influence of hand width on performance metrics is not well-established.

Purpose of the Study:

  • To investigate the effects of varying hand widths on plyometric push-up performance.
  • To determine if hand width placement influences key performance indicators like force and power.

Main Methods:

  • Ten male subjects performed plyometric push-ups at 120%, 150%, and 170% of their biacromial width.
  • Force plate data were collected for height, peak force, peak power, and rate of power development.
  • Statistical analyses included repeated-measures ANOVA and mixed-effects linear regression.

Main Results:

  • No significant differences were found in overall performance measures across hand widths using ANOVA.
  • Regression analysis revealed a significant difference in peak force between 120% and 170% hand widths.
  • Upper-body power output appeared consistent, but force development varied with hand width.

Conclusions:

  • Hand width placement can significantly affect peak force during plyometric push-ups.
  • While upper-body power may not be greatly impacted, force development is sensitive to hand width.
  • Consideration of hand width is recommended when using plyometric push-ups for performance assessment.
