Summary
Heart rate variability (HRV) in handball players remained stable after mild jogging, unlike sedentary individuals. This suggests athletes maintain sympathovagal balance during short, low-intensity exercise.
Area of Science:
- Sports Physiology
- Autonomic Nervous System Function
- Cardiovascular Regulation
Background:
- Heart rate variability (HRV) is a key indicator of autonomic nervous system (ANS) function.
- Assessing HRV responses to exercise differentiates physiological adaptations in athletes versus sedentary individuals.
Purpose of the Study:
- To evaluate heart rate variability (HRV) in professional handball players compared to sedentary controls.
- To determine the impact of a short, mild jogging exercise on HRV parameters in both groups.
Main Methods:
- Electrocardiogram (ECG) recordings were taken at rest and post-exercise in 12 male handball players and 14 sedentary males.
- Calculated time-domain (e.g., HR, NN intervals, pNN50) and frequency-domain (e.g., LF, HF, LF/HF ratio) HRV parameters.
- Statistical analyses included unpaired and paired t-tests and Pearson correlations.
Main Results:
- Systolic blood pressure and heart rate increased with exercise in both groups.
- Handball players exhibited slower heart rates and higher QTc intervals compared to controls.
- Exercise decreased pNN50 values in both groups, but the LF/HF ratio increased only in sedentary subjects.
Conclusions:
- Mild, short-duration jogging does not alter sympathovagal balance in professional handball players.
- Sedentary individuals showed increased sympathetic regulation or vagal withdrawal following the exercise bout.

01:30Factors Influencing Heart Rate
7.4K
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

2.8K
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

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.
