Summary
Different hand positions during push-ups alter palmar pressure distribution. Understanding these pressures can help modify exercises, especially for injured athletes, to prevent pain and improve safety.
Area of Science:
- Biomechanics
- Exercise Physiology
- Sports Medicine
Background:
- Push-ups are a common upper body exercise, but can cause pain.
- Palmar pressure during push-ups has not been previously studied.
- Hypothesis: Hand position affects palmar pressure.
Purpose of the Study:
- Investigate palmar pressure variations with different hand positions during push-ups.
- Provide data for exercise modification and injury prevention.
Main Methods:
- Ten volunteers performed push-ups in five hand positions.
- Palmar pressure was measured using an Emed pressure platform.
- Pressure distribution across five palm regions was analyzed.
Main Results:
- Lunate and hypothenar areas showed higher mean peak pressures.
- Wider hand positions (30 cm wider than shoulders) increased lunate pressure.
- Narrower hand positions (10 cm narrower than shoulders) increased hypothenar pressure in full flexion.
Conclusions:
- Palmar pressure varies significantly with hand position during push-ups.
- Findings can guide exercise modifications for athletes.
- This information is crucial for preventing palmar and wrist injuries.

01:27Assessment of the Cardiovascular System III: Palpation
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

01:23Assessment of blood pressure in brachial artery(two-step method)
Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...
01:24Pressure Relationships in Thoracic Cavity
Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs during...

01:21Sites for measuring blood pressure
Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

01:16Pulse
When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
