Summary
Concurrent training with sprint interval exercise showed no impact on resistance training performance. However, running intervals led to higher perceived exertion and lower wellbeing compared to cycling or control conditions.
Area of Science:
- Sports Science
- Exercise Physiology
- Concurrent Training
Background:
- Concurrent training, combining aerobic and resistance exercise, can cause interference, potentially reducing training adaptations.
- Sprint interval exercise (SIE) is a time-efficient aerobic training method.
- The choice of exercise modality for SIE may influence its compatibility with subsequent resistance training.
Purpose of the Study:
- To investigate the acute effects of cycling versus running SIE on subsequent resistance training performance and subjective feelings.
- To compare the interference effects of different aerobic exercise modalities within a concurrent training framework.
Main Methods:
- Twenty-five male rugby players completed three conditions: resistance training only (CONTROL), or resistance training preceded by cycling SIE (CYCLE) or running SIE (RUN) with 4 hours rest.
- Muscle performance (bar velocity, jump height) and subjective ratings (exertion, wellbeing) were measured.
- The SIE was performed in the morning, followed by resistance training in the afternoon.
Main Results:
- No significant differences in muscle performance (bar velocity, jump height) were found between the CONTROL, CYCLE, and RUN conditions.
- Running SIE resulted in significantly higher ratings of perceived exertion and lower subjective wellbeing compared to both CONTROL and CYCLE conditions.
- Subjective wellbeing was significantly lower following the RUN condition compared to the CONTROL condition.
Conclusions:
- The modality of SIE (cycling vs. running) does not appear to compromise the acute resistance training session's quality in terms of muscle performance.
- Running-based SIE may lead to greater subjective fatigue and reduced wellbeing compared to cycling-based SIE when integrated into a concurrent training program.
- Cycling SIE may be a more suitable aerobic component for concurrent training programs aiming to minimize subjective fatigue and maintain wellbeing.

1.6K
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...

01:22Muscle Stimulation Frequency
2.8K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.

2.1K
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

01:24Muscle Recovery and Fatigue
2.7K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

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.
