Abstract:
This study examined the training load on professional soccer players during transition games performed with different bout durations and their effects on speed and jump tests. Fourteen young soccer players played a transition game of different bout durations: 15 (TG15), 30 (TG30), and 60 (TG60) seconds. Total distance covered (DC), accelerations and decelerations above 1.0 and 2.5 m·s-2, rate of perceived exertion (RPE), maximal heart rate (HRmax) and above 90% (HR>90), distance covered between 18.0-20.9 km·h-1 (DC 18.0-20.9 km·h-1), 21.0-23.9 km·h-1 (DC 21.0-23.9 km·h-1), above 24.0 km·h-1 (DC>24.0 km·h-1), peak speed, sprint profile, sprint, and countermovement jump tests were recorded. TG15 obtained greater DC, DC>21.0 km·h-1, Player load, Acc>2.5 m·s-2 than TG30 and TG60 (p<0.01) and Acc<2.5 m·s-2, Dec>2.5 m·s-2 than TG60 (p<0.01). TG30 showed more HR>90 and RPE (p<0.01) than TG15, and DC, DC>18.0 km·h-1, Player load, Acc>2.5 m·s-2, Dec>2.5 m·s-2, HR>90 and RPE than TG60 (p<0.01 and<0.05). Transition games showed lower sprint and jump results after the intervention (p<0.01). Bout duration has been configured as an important constraint that influences the transition games and the performance of soccer players.

Exercise and Muscle Performance
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...

Motor Unit Stimulation
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...

Exercise and Cardiovascular Response
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...
