Abstract Objective: Military populations require a range of physical capabilities to meet the demands of the military profession. It is not known whether a specific within-session balance of the core components of physical fitness provides more effective training adaptations. The purpose of this research was to determine the effects of combinations of high-intensity endurance training, resistance training, anaerobic training and plyometric training. Methods: Twenty-eight healthy young cadets participated in an 8-week training program. Training was performed 6 days per week. Testing occurred before and after the 8-week training regimen. The pre- and post-training measures included the basic physiological and performance levels.Results: Physiological indices, such heart rate, heart rate variability, anaerobic power and maximal oxygen uptake, responded positively to training (P < 0.05). The components of physical fitness, such as muscle maximal strength and endurance, 600 all-out effort, 5000-m run time and 18-km military load carriage, were also significantly improved (P > 0.05). However, the jump capacity did not significantly increase. Conclusion: The results of this study indicate that during short-term integrative training, the lower-limb muscle maximal power did not improve. Given that many military tasks demand explosive (power) abilities, a switch to integrative training may have far greater consequences for transferring the benefits of the training program to military human performance.

Purpose: To analyze the effects of a 9-week plyometric training program on the sprint times (5, 10, 20, and 30 m), change-of-direction speed (modified T test and modified Illinois test), jumping (squat jump, countermovement jump, countermovement jump with arms, and horizontal 5-jump test), upper-body strength (right and left handgrip, back extensor strength, and medicine ball throw), and balance (Y and stork balance tests) of female handball players. Methods: Athletes were randomly divided into experimental (n = 21; age = 13.5 [0.3] y) and control (n = 20; age = 13.3 [0.3] y) groups. Training exercises and matches were performed together, but the experimental group replaced a part of their normal regimen by biweekly upper- and lower-limb plyometric training. Results: Both groups improved performance, but to a greater extent in the experimental group compared with controls for 20- and 30-m sprint times (Δ% = 9.6, P < .05, d = 0.557 and Δ% = 20.9, P < .001, d = 1.07, respectively), change of direction (T test: P < .01, Δ% = 14.5, d = 0.993 and Illinois test: P < .01, Δ% = 7.9, d = 0.769), vertical and horizontal jumping (P < .05), all measures of upper-limb strength (P < .001), and left-leg stork balance (P < .001, Δ% = 49.9, d = 1.07). Conclusions: A plyometric training program allows female junior handball players to improve important components of their physical performance.

The development of muscle power should be taken into account in soccer training. The aim of this study was to evaluate the influence of a 6-week of mixed power training on the level of the motor skills of the lower limbs of young soccer players. The training was conducted during the starting period. The study included twelve 16-18-year-old players who regularly participated in specific soccer trainings and played in regional competitions. Their basic anthropometric features were measured. The assessment of the power of the lower limbs was carried out using two jump tests: CMJ and SJ. The maximum anaerobic power was calculated and was expressed in relation to body weight and lean body mass. In addition, Drop Jump tests were performed from three different heights on the basis of which RSI reactive strength index were calculated. On completion of the training program an increase in the level of the results of all the tests was observed: SJ (cm) (cohen's d: 0.43), CMJ (cm) (cohen's d: 0.33), SJPmax (W/kg) (cohen's d: 0.43), CMJPmax (W/kg) (cohen's d: 0.30), SJPmax (W/LBMkg) (cohen's d): 0,57), CMJPmax (W/LBMkg) (cohen's d: 0,44), RSI 0,2 (cohen's d: 0,59), RSI 0,3 (cohen's d: 0,45), RSI 0,4 (cohen's d: 0,58). An additional six-week ballistic-plyometric training program, used as a supplement to the basic training plan during the start period, resulted in an increase in the motor skills of the lower limbs of young soccer players. The application of combined ballistic and plyometric training methods helps to improve the strength and speed potential of young soccer players.

The aims of the present study are twofold: 1) to investigate whether heart rate recovery (HRR) after a cycle ergometry test is affected by exercise training and 2) to test the ability of HRR to replicate the baroreflex sensitivity (BRS) changes that occur in response to an exercise training program in coronary artery patients. We randomized 82 coronary artery patients undergoing a residential cardiac rehabilitation program to an exercise training group (TR; n = 43) and an untrained group (UTR; n = 39). All of the patients underwent an exercise test before and after the rehabilitation program. HRR was recorded at the end of the 1st and 2nd min after exercise. BRS was determined at rest before and after treatment. HRR after the 2nd min was significantly improved in TR patients (−21.4 ± 0.9 beats/min) compared with UTR patients (−17.8 ± 1.2 beats/min) at the end of the training program. Improvement in HRR paralleled that in BRS in TR patients (from 3.2 ± 0.3 to 5.3 ± 0.8 ms/mmHg; P < 0.001), whereas no significant change was evident in UTR patients (from 3.5 ± 0 to 4.0 ± 0.4 ms/mmHg; P = 0.230). Our data show that HRR in the 2nd min after the cessation of a cycle ergometer exercise test increased in coronary artery patients after an exercise training period. This result confirms the positive effect induced by exercise training on HRR and extends the conclusions of previous studies to different modalities of exercise (i.e., cycle ergometer). HRR might provide an additional simple marker of the effectiveness of physical training programs in cardiac patients.

PURPOSE: Muscle strength, power, speed, postural stability, and anaerobic power are important physical fitness factors required to perform well in a taekwondo competition. This study aimed to investigate the effects of 8 weeks of core balance and plyometric training on physical fitness in young taekwondo athletes.METHODS: Nine young taekwondo athletes participated in this program. Body composition and relative fitness (muscle power, core strength, agility, postural stability, anaerobic power, and isokinetic muscle function) were measured before and after training. Data were analyzed using IBM SPSS Statistics version 23.0 (IBM Corp., Armonk, NY, USA). A paired t-test (pre vs. post) was used for the analysis.RESULTS:The core strength measured by the sit-up count changed significantly after training (<i>p</i><.05). In case of postural stability, the right absolute reach distance in the Y-balance test improved significantly after training (<i>p</i><.05). In case of anaerobic power, the mean power (<i>p</i><.01) and the peak power (<i>p</i><.01) increased significantly after training.CONCLUSIONS:We demonstrated that 8 weeks of core balance and plyometric training enhanced core strength, balance, and anaerobic power in young taekwondo athletes. Our results suggest that core balance and plyometric training are effective in improving muscle strength, core strength, balance, and anaerobic power.

This study was undertaken to investigate the effect of two different concepts in a training program on muscle thickness and anaerobic power in trained cyclists. Twenty-six mountain bike cyclists participated in the study and were divided into an experimental group (E), which performed polarized training, comprising sprint interval training (SIT), high-intensity interval training (HIIT), and endurance training (ET), and a control group (C), which performed HIIT and ET. The experiment was conducted over the course of 9 weeks. Laboratory tests were performed immediately before and after the conducted experiment, including an ultrasound measurement of the quadriceps femoris muscle thickness and a sprint interval testing protocol (SITP). During the SITP, the cyclists performed 4 maximal repetitions, 30 s each, with a 90-s rest period between the repetitions. SITP was performed to measure maximal and mean anaerobic power. As a result of the applied training program, the muscle thickness decreased and the mean anaerobic power increased in the experimental group. By contrast, no significant changes were observed in the control group. In conclusion, a decrease in muscle thickness with a concomitant increase in mean anaerobic power resulting from the polarized training program is beneficial in mountain bike cycling.

ABSTRACT Introduction The purpose of this study was to investigate sex-specific lower limb biomechanical adaptations during a standardized load carriage task in response to a targeted physical training program. Materials and Methods Twenty-five healthy civilians (males [n = 13] and females [n = 12]) completed a load carriage task (5 km at 5.5 km·h−1, wearing a 23 kg vest) before and after a 10-week lower-body–focused training program. Kinematics and ground reaction force data were collected during the task and were used to estimate lower limb joint kinematics and kinetics (i.e., moments and powers). Direct statistical comparisons were not conducted due to different data collection protocols between sexes. A two-way repeated measures ANOVA tested for significant interactions between, and main effects of training and distance marched for male and female data, respectively. Results Primary kinematic and kinetic changes were observed at the knee and ankle joints for males and at the hip and knee joints for females. Knee joint moments increased for both sexes over the 5 km distance marched (P &gt; .05), with males demonstrating significant reductions in peak knee joint extension after training. Hip adduction, internal rotation, and knee internal rotation angles significantly increased after the 5 km load carriage task for females but not males. Conclusion Differences in adaptive gait strategies between sexes indicate that physical training needs to be tailored to sex-specific requirements to meet standardized load carriage task demands. The findings highlighted previously unfound sex-specific responses that could inform military training and facilitate the integration of female soldiers into physically demanding military roles.

Objectives: The aim of this research was to study the effects of a course of water therapy and jogging on factors related to the physical fitness of elderly women. Methods: Semi experimental study was performed by pretest-posttest design in which elderly women over 60 (64.3 ± 2.5 years old) were randomly divided into 3 groups of water therapy exercises, jogging group (JG) and control group (CG). Factors related to physical fitness (lower limb muscle strength test, static balance, dynamic balance and physical flexibility) before and after interventional exercises. One-way ANOVA and Tukey's post hoc test were applied to analyze the data. Results: It was shown that both water therapy exercises and jogging had a significant effect on static (P = 0.03), dynamic (P = 0.04), lower limb strength [P = 0.03 and (P = 0.01) for WTE and JG, respectively] and physical flexibility scores (P = 0.03), but there was no significant difference between the two experimental groups in all research variables (P ≥ 0.05). Conclusions: The use of water therapy and jogging exercises leads to improved static and dynamic balance, muscular strength of the lower extremities. Since improving the motor performance variables has a significant effect on preventing the falling of the elderly, it is recommended to use these exercises for the elderly.

The present research aimed to study the effect of three different training periodization (traditional, reverse, and free training) on the aerobic performance, motivation, and adherence of physically active athletes. We analysed the adherence to three different periodization training programs: traditional, reverse, and free training periodization on the adherence of amateur triathletes. For this aim, the individual adherence, motivation, and aerobic performance time and heart rate (in a 1000 m running test) were evaluated before and after the completion of the three different 8-week periodization programs. The level of adherence to the reverse periodization was significantly higher than in traditional and free training. The number of dropouts in reverse and traditional periodization was similar but lower than in the free training. Finally, neither of the periodization programs improved aerobic performance and reverse training periodization decreased heart rate of participants in a 1000 m running test.

ABSTRACT Introduction The purpose of this study was to identify and characterize sex-specific physical and psychophysical performance adaptations in response to a novel 10-week training program. Materials and Methods Fifteen males and thirteen females completed a standardized load carriage task (5 km at 5.5 km.h−1, wearing a 23 kg torso-borne vest) before and after 10 weeks of resistance and load carriage training. Psychophysical responses (i.e., heart rate and ratings of perceived exertion) were measured throughout the load carriage task. Physical performance (i.e., countermovement and squat jumps, push-ups, sit-ups, and beep test) was measured at before, mid-way, and after the training program (weeks 0, 6, and 11, respectively). Results Training elicited significant improvements in squat jump maximal force, push-ups, and beep test performance (P &lt; .05). Males outperformed females in all performance measures, with interactions (time, sex) for push-ups, sit-ups, and beep test performance. After training, aerobic capacity improved by 5.4% (42.9 mL· kg−1· min−1 to 45.2 mL· kg−1· min−1) in males but did not improve in females. Psychophysical responses decreased for both sexes (P &lt; .05) during the load carriage task post-training. Conclusion While 10 weeks of standardized training elicited positive adaptations in both physical and psychophysical performance, sex-specific differences were still evident. To lessen these differences, sex-specific training should be considered to optimize load carriage performance.
