The Relationships Between External and Internal Workloads During Basketball Training and Games
International Journal of Sports Physiology and Performance
|August 20, 2020
Summary
PlayerLoad and summated heart rate zones show the strongest relationship between external and internal workloads in basketball players, especially during training. This helps coaches manage player load effectively throughout the season.
Area of Science:
- Sports Science
- Biomechanics
- Exercise Physiology
Background:
- Understanding the relationship between external and internal workloads is crucial for optimizing athlete training and preventing injuries.
- Previous research has explored various metrics, but a comprehensive analysis during basketball-specific activities is needed.
Purpose of the Study:
- To investigate the relationships between a wide range of external and internal workload variables in semiprofessional male basketball players.
- To differentiate these relationships during training sessions versus competitive games.
Main Methods:
- Eight semiprofessional male basketball players were monitored over a full season.
- External workload was measured using PlayerLoad™ (accelerations, decelerations, changes of direction, jumps) and inertial movement analysis events.
- Internal workload was assessed via summated heart rate zones and session rating of perceived exertion.
Main Results:
- PlayerLoad demonstrated a very large correlation with summated heart rate zones (r = .88 in training) and session rating of perceived exertion (r = .74 in training).
- Relationships between external and internal workload variables were consistently stronger during training sessions (r = .44-.88) compared to games (r = .15-.69).
Conclusions:
- PlayerLoad and summated heart rate zones exhibit the most robust dose-response relationship among the assessed workload variables in basketball.
- These findings suggest that coaches can better predict player responses and manage workload by utilizing PlayerLoad and heart rate data, particularly during training.

Social Facilitation
35.8K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Internal and External Forces
15.7K
Newton's first law states that a net external force causes a change in motion. External forces act on an object or system, originating outside of the object or system. In contrast, internal forces originate inside the system of interest and do not lead to any acceleration. In simpler words, internal forces are forces that act on one part of an object and are exerted by another part of the same object. External forces are forces that act on an object due to some other object. Therefore, when...

Internal forces and the center of gravity are fundamental concepts in mechanics, playing a crucial role in understanding the behavior and stability of structures and objects under various conditions. A comprehensive understanding of these principles is essential for engineers, architects, and designers to create safe and efficient systems.
Internal forces are generated within a body due to the interaction between its particles. These forces can be categorized into tension, compression, and...

Exercise and Cardiac Output

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.

Exercise and Muscle Performance
2.1K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

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...
