Single-nucleus RNA-seq identifies transcriptional heterogeneity in multinucleated skeletal myofibers. Because ROS production is also greatly dependent on Δψ and electrochemical gradient and because uncoupling proteins U can affect these parameters, levels of UCP3 protein were also quantified.

Both the control trial and the exercise trial will last for 3 months. During a week before the start of the study, participants will complete dietary recalls and record their habitual physical activity using accelerometers.

Thereafter, body composition, ultrasound imaging of the muscle and liver, biochemical and hematological markers were measured. This range of measurements will be repeated the ended each month for both trials. Control trial succeeds exercise trial.

An exercise intervention program will take place in the second trial, three times a week. A sample size of 30 volunteers, aged years, will participate in the present study. The exclusion criteria will be a medication, b musculoskeletal problems that will prevent participation in the training program, c known condition or medical condition preventing participation in the program e.

After informing and receiving a questionnaire and medical history, volunteers will sign for their participation in the survey. A two-trial repeated measures design will be applied in this investigation.

Both control and exercise trials will last for 3 months. During the week preceding the commencement of the study, participants will complete dietary recalls and will have their habitual physical activity monitored, by utilizing accelerometers.

Thereafter, body composition, ultrasound imaging of muscle and liver, biochemical and hematological markers will be measured. The same measurements will be repeated at the end of each month, in both trials.

The test-retest reliability of TT and IAT were 0. The details of this test have previously been described elsewhere Bangsbo et al.

Briefly, the test involved shuttle runs of 20 meters, where the speed increased progressively during the assessment. Then, the complete distance covered by each participant was recorded for future analysis.

Following the test, the following formula estimated V̇O 2max Bangsbo et al. After overnight fasting exceeding 8 hours, a mL of blood was collected from the antecubital vein in the pre- and post-training.

The sample was centrifuged at 3, rpm for 15 min at 4 °C and stored at °C until further analysis. Serum testosterone TEST and cortisol CORT were analyzed using ELISA kits Monobind, Inc.

Lake Forest, California , USA. All participants engaged in their formal basketball training twice a week i. The training lasted approximately 60 to 70 minutes and was completed in the afternoon, from to PM. In addition to formal basketball training, the SIT groups completed ~30 min traditional SIT or SSIT before their regular basketball session, and participants of the CON group only performed tactical and technical basketball training.

Formal basketball training consisted of general warm-up, basketball-specific ball drills, reviewing tactical strategies and performing them with a low- to moderate-intensity, and cool down.

Each training session was initiated with a min warm-up consisting of 5 min running, 5 min dynamic stretching, and 5 min sprint and ballistic movements.

Following the warm-up, the subjects in SIT performed three sets of 7, 8, 9, 10, 10, 10 repetitions from the 1 st to 6 th week, respectively × sec all-out runs with a sec recovery between efforts and a 3-min recovery between the sets.

All SSIT sessions were similar to SIT in sets and duration but were performed with the ball using dribbling and passing drills. For example, the SIT group ran a sec in direct track, while the SSIT ran sec in direct track with the ball during individual dribbling or passing with a teammate.

All-out and supra-competitive skill-based exercises were performed without opposition i. We employed different offensive drills simulating basketball movement patterns requiring sprinting and reaching, with simple decision-making, allowing maximal effort Laursen and Buchheit, The training sessions were monitored by Specialized Strength and Conditions Coach to ensure all training sessions were completed correctly.

Assuming an alpha level of 0. All data are presented as mean ± standard deviation SD. A group SIT, SSIT, and CON × time pre-training, post-training repeated-measures analysis of variance ANOVA compared the differences between groups.

Significant interactions or main effects were subsequently analyzed using a Bonferroni post-hoc test. The statistical analysis was performed utilizing the SPSS statistical software, version No significant pre- to post-training change was observed for SLJ in SIT and SSIT groups Figure 4, B.

The present study aimed to compare the effects of traditional SIT and sport-specific SIT SSIT on physiological and biochemical adaptations and bio-motor abilities in male basketball players.

The most striking finding of the present study was that both traditional SIT and SSIT significantly improved the abovementioned parameters. However, effect size values indicate greater effects of SSIT on aerobic and anaerobic performance than SIT. Research has shown a positive relationship between aerobic fitness and power recovery between repeated bouts of intensive interval exercise Laursen and Buchheit, This observation implies that aerobic fitness plays a pivotal role in a crucial aspect of basketball performance, i.

The increased running distance completed during the Yo-Yo IR1 test in both SIT and SSIT groups could also verify this improvement. In the present study, both SIT and SSIT imposed an effective stimulus for improving V̇O 2max and significantly enhanced this indicator.

Our findings corroborate previous studies reporting enhanced aerobic fitness following game-based Arslan et al. The enhancement of V̇O 2max can be attributed to increases in two fundamental aspects of aerobic fitness: the central component, involving the improved delivery of oxygen, and the peripheral component, which signifies the enhanced utilization of oxygen by the active muscles Sheykhlouvand et al.

Anaerobic energy metabolism is the primary determinant of high-intensity movement performance, such as jumping, sprinting, and change of direction Arslan et al. Both SIT and SSIT significantly enhanced these sport-specific bio-motor abilities, indicating their positive effects on anaerobic power.

The increase in VJ observed in this study SIT: 7. However, some researchers failed to show the positive effects of SIT on VJ Aschendorf et al. The observed disparities in the outcomes might stem from variations in the duration of the training, gender, fitness levels of the participants, and the specific mode of training employed.

Enhanced explosiveness in VJ could be attributed to parameters such as reactive strength and muscular power Panoutsakopoulos and Bassa, However, neither SIT nor SSIT enhanced 1RM LP , indicating that enhanced neuromuscular adaptations such as increasing rate of force development and firing rate of muscles Buchheit and Laursen, and anaerobic power production of plantar flexors and knee extensors Maffiuletti et al.

We can speculate implementing SSIT, involving sport-specific drills such as dribbling, passing, and shooting exercises, resulted in more significant neuromuscular adaptations than regular SIT, leading to greater training effects with an effect size of 0.

Nonetheless, further investigations are necessary to elucidate the specific adaptations achieved through this approach. Regarding the sprint performance, both SIT and SSIT groups enhanced this locomotor ability after six weeks.

An increase in sprint acceleration and velocity due to interval intervention involves fast-twitch muscle fiber and also improvements in stride length resulting in sprint gains Lee et al. Our finding is in accordance with previous studies reporting a positive transfer of SIT to sprint performance Clemente et al.

SSIT indicated greater changes in the m sprint than SIT medium vs. small ES. The possible mechanism explaining such a difference could be the enhanced acceleration component of the maximal sprint test due to sport-specific movements during SSIT Arslan et al. Both SIT and SSIT significantly diminished TT and IAT time.

In addition, the changes in IAT were significantly greater in the SSIT than in the SIT. Likewise, Arslan and colleagues have shown small vs. moderate training effects of HIIT and small-sided games on these parameters.

COD presents a key attribute in basketball. A quick COD requires rapid force development and high power generation by the lower extremities Miller et al. In COD ability tasks, the leg extensor muscles undergo swift transitions between eccentric and concentric muscle actions, accompanied by minimal ground contact time Miller et al.

Effect size results indicate a greater impact of SSIT on COD, which could be attributed to the sport-specific drill during SSIT i. By challenging the neuromuscular system and decision-making ability through basketball-specific drills, such movements may indirectly benefit the ultimate COD better than linear running Arslan et al.

Both SIT interventions were associated with an increase in TEST levels and a decrease in serum CORT concentrations.

Our results corroborate previous findings Sheykhlouvand et al. Typically, elevations in resting TEST with reductions in CORT show an anabolic environment and increase performance capacity in athletes. Enhanced resting TEST levels represent a favorable hormonal environment when attempting to maximize performance adaptations.

This study possesses certain limitations that warrant consideration when interpreting its findings. Firstly, the study exclusively involved male subjects, which restricts the generalizability of our results to the broader population. Gender-based differences in physiology and responses to interventions may exist, and further research with diverse participant groups is necessary to ascertain the applicability of our findings to women.

Secondly, the study acknowledges the potential influence of external factors outside of the intervention, such as dietary habits, sleep patterns, and overall training load. While we tried to control these variables and maintain consistency among participants, we cannot entirely exclude the impact of these factors on the observed outcomes.

Future research could employ more rigorous control measures or investigate these external factors as variables of interest to understand their effects on the studied intervention better.

Specifically, the post-training analysis indicated that both interventions were linked with enhanced aerobic fitness, VJ, COD, linear speed, and anabolic hormonal status.

The effect size values indicated more significant effects of SSIT than SIT in most physiological and sport-specific adaptations. Moreover, sport-specific practices may impose more challenging movements mimicking the game and cause more significant gains than SIT performed on a direct track.

Similarly, most literature suggests little change in muscle fiber percentage in slow-twitch and fast-twitch fibers; however, changes have been documented in fast-twitch subtypes. Type IIx fast-twitch fibers have called upon less during cardiovascular training, consequently, possess a lower aerobic capacity.

Recent literature produced by the HERITAGE study suggests that type IIx fast-twitch fibers may transform to type IIa and it is even speculated they may be capable of transitioning to slow-twitch. However, very minuscule results have been published. A significant adaptation to cardiovascular training is the increase in capillaries surrounding the muscle fibers.

Literature has documented that cardiovascular trained individuals have significantly greater amounts of capillary density than compared to sedentary populations. Upon entering the muscle, oxygen binds with an iron-containing compound that resembles hemoglobin called myoglobin.

Myoglobin transports oxygen molecules from the cell membrane to the mitochondria. Of importance to cardiovascular training, myoglobin has the capacity to store oxygen and release it, particularly when oxygen becomes sparse during muscle contraction.

The release of oxygen often occurs during the lag time between the beginning of exercise and the amplified cardiovascular transportation of oxygen. This adaption of muscle significantly impacts the ability for oxidative metabolism. Aerobic energy production occurs within the mitochondria.

Therefore the affect on the mitochondrial function is obvious. The major adaptations with cardiovascular training on the mitochondria are increases in size and number. As the volume of cardiovascular training rises, so do the number and the size of the mitochondria.

Mitochondrial efficiency and the oxidative formation of ATP are increased by oxidative enzymes. Training induced enzyme activity contributes not only to the number and size of the mitochondria, but also to the metabolic consequence of mitochondrial changes.

It is suggested that increased enzyme activity creating mitochondrial changes creates a slower use of muscle glycogen and a reduced production of lactate during exercise at given intensities. This adaptation is likely to have great importance to ones lactate threshold.

Muscle glycogen is often the primary substrate for cardiovascular exercise. The primary response for depleted glycogen storage is a heighted resynthesis capacity. With proper recover and dietary intake, cardiovascularly trained muscle stores significantly greater amounts of glycogen.

Furthermore, muscular enzymes responsible for lipid breakdown are increased with cardiovascular training. This adaptation allows for trained muscle to oxidize lipids, decreasing the breakdown of glycogen. In addition to the cardiovascular adaptations and benefits discussed above, lactate training results in a few other key muscle adaptations.

Lactate training places high stress on the glycolytic system within the muscle resulting in high amounts of lactate accumulation. Training under the presence of lactate will lead to increased removal avenues.

Increased lactate transporter, monocarboxylate MCT and mitochondrial proteins are expressed in greater capacities in response of higher lactate concentrations and heighten the muscles potential for lactate removal.

Intercellular buffer capacity also contributes to the removal of lactate during lactate training. Physicochemical buffering proteins, dipeptides and phosphates within skeletal muscle increase the efficiency of lactate removal when lactate training is performed.

Similarly, the local formation of lactate within skeletal muscle is theorized as a potential mechanism for adaptation of muscular pH regulation. PH displacement during lactate training may result in adaptations for improved lactate clearance.

The overall adaptation of lactate training is to increase lactate tolerance of skeletal muscle. Buffering and removal capacities of skeletal muscle allow for increased concentration of muscle and blood lactate.

Thus, neutralizing the effect lactate plays on muscle, therefore delaying performance fatigue. One of the most significant adaptations of ATP-PC training that explains much of the gains that are made by the athletes that are trained are neural.

Motor unit recruitment and synchronization explain much of the gains that are made during ATP-PC training in the absence of hypertrophy.

Similarly, the more units recruited to perform muscle actions, lead to maximal contraction capabilities. Autogenic inhibitory mechanisms i.

Co-activation agonist and antagonist muscles may be another neural factor to ATP-PC training. Reducing the amount of resistive force of antagonist muscle may contribute to greater force production of agonist muscles.

Although speculated to provide minimal contribution, the reduction of co-activation may contribute to neuromuscular adaptations leading to greater force production. Finally, rate coding may be a contributing neuromuscular factor contributing to greater force production succeeding ATP-PC training.

The firing frequency of motor units, known as rate coding, may also lead to force generating improvements. Although not well documented, evidence does exist to underpin this ATP-PC training mechanism. Hypertrophy: Two types of muscle hypertrophy occur with ATP-PC training.

The first,. Transient lasts only a short time immediately after a training bout and is caused by fluid buildup from blood plasma in the interstitial and intercellular spaces within muscle.

Chronic hypertrophy reflects the actual muscle structure size increases that are a result of fiber hypertrophy increase in existing fiber size or fiber hyperplasia increase in actual number of fibers.

Early research established that the number of muscle fibers an individual possess is genetic and the alteration of muscle size rests solely in fiber hypertrophy. However, a growing amount of animal research suggests hyperplasia is a result of ATP-PC training, but only a few studies represent hyperplasia occurring in humans.

Myosin heavy chain II: In addition to cross sectional muscle area increases hypertrophy ,. additional myosin heavy chain II isoforms are present as a result of ATP-PC training. Type I and Type II fiber area: ATP-PC training also has the ability to alter muscle fiber area.

Heavily trained subjects depending on training intensity and volume have experienced major alteration in type II muscle fiber diameter in comparison to type I. Chronic ATP-PC training can have the ability to affect the aerobic metabolism of type I fibers.
