Effect of Plyometrics Training on Explosive Strength and Speed Performance of Long Jumpers

The purpose of this study was to assess the effect of plyometric training on explosive strength & speed performance of long jumpers. Various studies suggest that plyometric training improves explosive strength and speed performance. However, the effectiveness of plyometric training depends upon several factors. Integrating plyometric training program aims to provide a comprehensive approach to performance enhancement. Based on their training, Seven male jumpers were divided into 2 groups: a plyometric training group (n=7), a weight training group and a control group (n=7). The program was designed to implement in starting phase of competitive season, where aim to maintaining peak performance and minimizing risk of injuries. The objectives of the study were to determine the effect of plyometric training on explosive strength and speed performance of Long Jumpers. Subjects in each of the training group trained five days per week, whereas control subjects did as usual/traditional training. The data was analyzed by a paired sample t-test. The results showed that all the training treatment of Strength test found elicited significant difference in mean compression while (P<0.05) and the compression of mean in speed test was also found significant difference and (P<0.05) respectively. The findings of this study reveal a significant improvement on both speed and strength performance. The researchers proved that the addition of plyometric training in a routine/traditional training program was more effective in improving of sprint and explosive strength performance. Researchers strongly recommend that athletics coaches implement plyometric training in training schedule to enhance the performance of their athletes.

Effects of circuit weight training by intensity on stress hormones and antioxidant capacity in high-school wrestlers.

We aimed to investigate the effects of 8-week circuit weight training by intensity on blood stress hormones and antioxidant capacity in high-school wrestlers. This study involved 27 male wrestlers with >2 years of wrestling experience who were randomly assigned to either a low intensity (n=13) or a high-intensity circuit weight training group (n=14). The participants performed circuit weight training for 60 min per session, 3 times per week for 8 weeks. The low- and high-intensity circuit weight training exercises were performed at 50%-60% and 70%-80% of one-repetition maximum for 10 stations, respectively, and 8-15 repeated sessions per station were performed in order. No changes were observed in adrenocorticotropic hormone (ACTH), cortisol, epinephrine, and norepinephrine levels between the two training groups. When compared to levels before the training, ACTH and epinephrine levels decreased, whereas cortisol levels increased. However, no difference was observed in norepinephrine levels. Further, no differences were observed in malondialdehyde (MDA) and glutathione peroxidase (GPX) levels between the two groups. However, MDA and GPX levels were increased from those before training. Changes in superoxide dismutase levels were observed between the two groups, but the change was significant only in the high-intensity circuit weight training group. Long-term training did not increase lipid peroxidation, but increased the activity of antioxidant enzymes that defend against oxidative stress. The antioxidant defense system in tissues can be regulated by exercise intensity as well as physical training status.

Body weight training versus series 7 diabetes dance: their influence on glucose levels in patients with type 2 diabetes mellitus

Managing blood glucose levels is critical for preventing complications associated with type 2 diabetes mellitus (T2DM). Physical activity has been shown to be an effective strategy for glucose control, with various forms of exercise yielding different results. This research aims to explore the effects of body weight training and series 7 diabetes dance on reducing blood glucose levels in patients with T2DM, and to compare the efficacy of these two interventions in achieving glucose control. The type of research was a quasi-experiment with a two groups pre-test post-test design. The series 7 diabetes dance group performed the exercise 4 times a week (duration: 170 minutes 8 seconds/week), while the body weight training group performed exercise 3 times a week (8 movements, number of repetitions close to failure, circuit system, 3 sets per training session). Both groups were doing an exercise program for three months. The research sample was for about 16 patients of type 2 diabetes mellitus (8 people per group, devided randomly), taken by using non probability sampling technique, purposive sampling type (effect size 1.6, significant level (α) 0.05 and Power 0.8). The data analysis used the paired sample t test and the independent t test with a significance level of α = 0.05.The results showed that 1) there is no significant effect of series 7 diabetes dance towards the decreasing the level of blood sugar of the patients with type 2 diabetes mellitus), 2) there is a significant effect of body weight training towards the decreasing level of blood glucose of the patients with type 2 diabetes mellitus, 3) dody weight training is more effective in decreasing the level of blood glucose of patients with type 2 diabetes mellitus compared to series 7 diabetes dance. Future research must be carried out as a true experiment with a larger number of samples and with the HbA1c research instrument.

The effect of plyometric training (hurddle jumps), body weight training (lunges) and speed on increasing leg muscle explosive power of futsal players: a factorial experimental design

Futsal games have high intensity and dynamics that require good skills and physical conditions, one of which is leg muscle explosiveness. By doing plyometric training (hurddle jump), body-weight training (lunges), and paying attention to explosive power factors including speed as a group determinant is believed to affect the explosive power of the player's leg muscles. However, despite recognizing the importance of both training methods in improving leg muscle explosive power, there is still a lack of a thorough understanding of their combined effect on players' leg muscle explosive power during futsal play. This study aims to analyze the differences in the effect of the intervention groups of plyometric training methods and body weight training by considering the level of running speed on explosive power results. Training groups include plyometric training groups and body weight training groups, while speed is categorized as high or low. Using an experimental approach with a 2 x 2 factorial design, this study randomly selected 20 players aged 17.1 ± 0.768 years. Training was conducted in three sessions per week for approximately six weeks. Training focused on fast/explosive movements. Speed data was collected using the 30m acceleration test and the leg muscle explosiveness standing broad jump test. The data were then statistically analyzed using a two-way ANOVA at the 0.05 level of significance. The results showed that both training methods can benefit individuals with high speed (P<0.05). However, leg muscle explosive power training with plyometric exercise was more effective on individuals with high speed (P<0.05). As for those with low speed, plyometric exercise can provide better results (P<0.05). These findings provide valuable insights for futsal coaches and instructors in designing customized training programs to improve leg muscle explosiveness.

The Effect of 12-Week Core Strengthening and Weight Training on Muscle Strength, Endurance and Flexibility in School-Aged Athletes

This study investigates the effect of 12-week core strengthening and weight training on muscle strength, endurance and flexibility in school-aged athletes. Ninety male athletes at the age of 12 were randomly divided into three equal groups (30 in each). Group 1 underwent core strengthening training, group 2 underwent weight training, and group 3 was the control. The training was for 12 weeks, with three sessions per week (one hour per session). Prior to and after the training, abdominal strength, endurance, and flexibility were evaluated using the sit-ups test, the Cooper 12 min run test and the sit and reach test. The analysis of variance was used to analyze pre- and post-intervention data. The results showed that both the core strength training group and the weight training group significantly (p = 0.00) improved in abdominal strength, represented by the number of sit-ups (from 18.70 ± 3.20 to 22.21 ± 3.50 and from 17.60 ± 3.29 to 21.60 ± 3.63, respectively); endurance, represented by distance covered in 12 min (from 1817 ± 185.78 m to 2008.97 ± 214.79 m and from 1806 ± 237.25 m to 2002.59 ± 83.32 m, respectively); and flexibility, represented by the sit and reach distance (from 23.48 ± 2.75 cm to 25.96 ± 2.38 cm and from 23.66 ± 2.92 cm to 25.86 ± 2.55 cm, respectively) when compared to the control group (from 17.20 ± 3.20 to 16.39 ± 2.69; from 1813 ± 224.69 m to 1778.15 ± 05.28 m; from 23.46 ± 3.06 cm to 21.76 ± 2.56 cm). More specifically, abdominal strength and endurance improved slightly more in the weight training group than in the core strength training group, whilst flexibility increased slightly more in the core strength training group than in the weight training group. These findings indicate that both core strengthening training and weight training are effective in improving physical fitness in school-aged athletes; however, the improvement is to differing extents regarding their endurance, flexibility, and abdominal strength.

Effects of Drop Jump Training from Different Heights and Weight Training on Vertical Jump and Maximum Strength Performance in Female Volleyball Players.

Sotiropoulos, K, Smilios, I, Barzouka, K, Christou, M, Bogdanis, G, Douda, H, and Tokmakidis, SP. Effects of drop jump training from different heights and weight training on vertical jump, maximum strength and change of direction performance in female volleyball players. J Strength Cond Res 37(2): 423-431, 2023-This study compared the effects of drop jump (DJ) training from different drop heights and weight training on vertical jump and maximum strength performance. Fifty-five female volleyball players (age: 23.8 ± 4.3 years) were randomly and equally allocated to a control group (volleyball training, CG); a volleyball and weight training group (WG); and 3 volleyball, weight, and drop jump training groups. One group performed DJ training from the optimal drop height, i.e., the height that elicited the highest ratio of jump height to contact time (OG), a second group from a drop height 25% higher than the optimal (HG), and a third group from a drop height 25% lower than the optimal (LG). Drop jump and weight training were performed 1-2 times per week, for 8 weeks for a total of 13 sessions. After training, vertical jump performance improved by 3.6-17.4% ( p < 0.05; effect size [ES]: 1.03-1.23) in the OG and the HG compared with the LG, WG, and CG ( p < 0.05; ES: 0.03-0.58). Drop jump height from drop heights 20-70 cm increased by 10.0-20.2% ( p < 0.05; ES: 0.59-1.13) for the OG and the HG, while reactive strength index increased ( p < 0.05; ES: 0.74-1.40) by 19.6-33.9% only in the HG compared with the CG. Half-squat maximum strength was increased in all experimental groups by 17.4-19% compared with the CG ( p < 0.05) with no differences ( p > 0.05) observed among them. The use of the optimal height or a moderately higher drop height by 25% for DJ training, combined with weight training, seems to be the most beneficial option to improve vertical jump and reactive strength index in female volleyball players.

The Effect of Two Resistance Training Methods on Dynamic Balance, Fall Risk, and Ankle Range of Motion in Active Elderly Women

The present study was conducted to investigate the impact of resistance training methods on dynamic balance, fall risk, and range of motion of ankle in active elderly women. Methods In the current quasi-experimental study, participants were 30 active elderly women (64.79±3.33) in Tehran who were randomly divided into two groups Theraband and weight training. The Y balance test evaluated dynamic balance, fall risk was assessed by the Timed up and Go test (TUG), and a goniometer evaluated ankle range of motion. Statistical analysis of data was conducted using independent and dependent t-tests (in significant level P=0.05) Results Results showed that Theraband training and weight training had a significant effect on fall risk and ankle range of motion Theraband training group was significantly superior to the weight training group in dynamic balance (P=0.001), fall risk (P=0.001), ankle range of motion (left: P=0.004 and right: P=0.001). Also, Theraband training significantly impacted dynamic balance (P=0.012). Conclusion According to the results, Theraband and weight training significantly improve the risk of falls and ankle range of motion in active elderly women. In addition, Theraband training influences dynamic balance positively. In conclusion, Theraband training affects all three research variables more than weight training.

Effect of Dry-Land Core Training on Physical Fitness and Swimming Performance in Adolescent Elite Swimmers.

Background:We aimed to investigate the effect of a 12-week dry-land core training program on physical fitness and swimming performance in elite adolescent swimmers.Methods:Thirty subjects were selected and assigned to the core training group (CTG, n=15) and the traditional weight training group (WTG, n=15) in Seoul, Korea, between Sep and Dec 2016. The field fitness test was performed to determine the isotonic maximum muscular strength (one repetition maximum of deadlift and cable pulldown), anaerobic power (Wingate test), core stability (sports-specific endurance plank), core muscular power (front abdominal power, side abdominal power), muscular endurance of limbs (push-up, endurance jump), and swim performance improvement (personal record). Differences between groups after the exercise intervention were analyzed using two-way analysis of variance with repeated measures.Results:There were no significant interactions in isotonic maximum strength, anaerobic power (mean power, fatigue index), core muscular power, muscular endurance of limbs (endurance jump), and swim record improvement (P>0.05). The anaerobic peak power (P<0.001), sports-specific endurance plank test (P<0.001), and push-up test (P<0.001) showed significant interaction effects.Conclusion:The 12-week dry-land core training program resulted in statistically significant improvements in anaerobic power, core stability, upper extremity muscular endurance, and swimming performance.

Flywheel or free weight training for improvement of lower limbs strength?

New training methods are constantly used to improve the ability of skeletal muscles to develop strength. The aim of the present study was to investigate the effect of half-squat training with free weights and flywheel device on isokinetic knee muscle strength for well-trained amateur soccer players. Forty eight players were randomly divided into three groups (n= 16 each): Desmotech Training group (DT), Free Weight Training group (WT) and one Control Group (CON). DT and WT performed an eight-week half-squat training program, with two sessions per week. The DT group performed training with a flywheel device. Isokinetic concentric-eccentric strength assessments of the knee extensors-flexors muscle groups were performed at different angular velocities (60, 180 and 240∘/s). The eight-week training program improved all the isokinetic joint moment indicators examined in the DT and WT groups (p< 0.01). The DT group achieved higher performances at all the isokinetic parameters examined, however, without statistically significant differences to the WT group. Flywheel-based exercise is an effective training method and is suggested to be used to strengthen the lower limbs of soccer players.

The Effects of Plyometrics and Weight Training on Power, Agility and Muscle Tone of Quadriceps and Hamstring

Purpose: This study compared the changes in power and agility and muscle tone of the quadriceps and hamstring muscles after 10 weeks of plyometrics or weight training to strengthen the leg muscles. The following conclusions were obtained. Methods: Subjects were randomly assigned to a plyometrics group (n = 10) and a weight training group (n = 10) from male college students who did not recently participate in a regular exercise program. Plyometrics and weight training were performed three times a week for 10 weeks with 60 minutes a day. The exercise intensity was divided into 3 stages, and the weight training group and the plyometrics group performed 3 sets of 1 repetition maximum (RM) of 60, 70, 80%, and 10, 12, 15 repetitions (rep), respectively. Results: First, there was an interaction effect between the group and time period on power. The plyometrics group showed a greater increase in power than the weight training group. Second, there was an interaction effect between the group and time period on agility. While agility improved in the plyometrics group, no significant difference was observed in the weight training group. Third, there was an interaction effect between the group and time period on the muscle tones of the left and right quadriceps muscles. The muscle tone increased more in the weight training group than in the plyometrics group. Fourth, there was an interaction effect between the group and time period on the muscle tones of the left and right hamstring muscles. The muscle tone increased more in the weight training group than in the plyometrics group. Conclusion: The change in muscle tone value was found to have a significant relationship with the increase in muscle strength and power through plyometrics and weight training, and additional research should be conducted to investigate the relationship between exercise performance ability and muscle tone.

The effect of elevating the heels on spinal kinematics and kinetics during the back squat in trained and novice weight trainers

ABSTRACTThis research assessed the influence of various heel elevation conditions on spinal kinematic and kinetic data during loaded (25% and 50% of body weight) high-bar back squats. Ten novice (mass 67.6 ± 12.4 kg, height 1.73 ± 0.10 m) and ten regular weight trainers (mass 66.0 ± 10.7 kg, height 1.71 ± 0.09 m) completed eight repetitions at each load wearing conventional training shoes standing on the flat level floor (LF) and on an inclined board (EH). The regular weight training group performed an additional eight repetitions wearing weightlifting shoes (WS). Statistical parametric mapping (SPM1D) and repeated measures analysis of variance were used to assess differences in spinal curvature and kinetics across the shoe/floor conditions and loads. SPM1D analyses indicated that during the LF condition the novice weight trainers had greater moments around L4/L5 than the regular weight trainers during the last 20% of the lift (P < 0.05), with this difference becoming non-significant during the EH condition. This study indicates that from a perspective of spinal safety, it appears advantageous for novice weight trainers to perform back squats with their heels slightly elevated, while regular weight trainers appear to realize only limited benefits performing back squats with either EH or WS.

서킷웨이트 트레이닝과 웨이트 트레이닝이 비만 남자대학생의 유산소성 운동능력과 건강관련체력에 미치는 영향

The purpose of this study was to investigate the effects of circuit weight training and weight training on aerobic capacity and health-related fitness in obese male college students. In this study 16 obese male college students attending G-city University without medical history were selected as subjects. These subjects were randomly assigned to circuit weight training group (n=8) and weight training group (n=8). The subjects in circuit(three circuits using a work-to-rest ratio of 30s:30s) and weight training program performed for 8 weeks, 3 times a week on non-consecutive days at 40 and 80% of one-repetition maximum(1RM), respectively. The maximum oxygen uptake(VO₂max) and oxygen uptake(VO₂) at anaerobic threshold(AT) were measured as the aerobic capacity. Also, body composition, muscular strength, and muscular endurance were measured and analyzed as the health-related fitness. Based on the results of the study, the following results were obtained. First, the maximum oxygen uptake and oxygen uptake at anaerobic threshold were significantly increased (p<.01) in the circuit weight training group, but there was no significant difference in the weight training group. Second, there was a significant decrease (p<.01) in body weight in the circuit weight training group, and a significant decrease (p<.001) in body fat(%) in both groups. In contrast, lean body mass was increased in both groups, but there was no significant difference. Third, There was a significant difference (p<.001) in muscular strength and muscular endurance in both groups. Therefore, circuit weight training may also be an effective exercise method for increasing potential aerobic capacity and reducing body fat in changes in body composition.

There is a personal difference in the anaerobic power of the according to the position, It is believed that an evaluation comparison of the resulting values obtained under the same conditions as inspections in the same position will be necessary. Therefore, it is hoped that football players will develop more specific and scientific data in training programs suitable for their position and purpose.

Effective Weight Loss and Maintenance by Intensive Start with Diet and Exercise.

This 24-month study aimed to determine whether exercise intervention added to weight loss treatment at 6 months is effective for weight loss and maintenance. A total of 120 obese subjects (body mass index > 30) were randomly assigned to intensified behavioral modification (iBM) (n = 30), behavioral modification + exercise from 0 to 3 months (circuit weight training group 1 [CWT1]) (n = 30), behavioral modification + exercise from 6 to 9 months (CWT2) (n = 30), and a control group (CON) (n = 30). Health behavior, weight, waist circumference, and 2-h glucose tolerance test with insulin measurements were measured at 0, 3, 9, and 24 months. Eighty-five subjects (mean age = 46 yr, body mass index = 36.3, 75.3% women) completed the trial. A significant weight loss occurred in CWT1 (-8.5 kg, P > 0.001), iBM (-5.5 kg, P > 0.001), and CWT2 (-4.4 kg, P = 0.007). CWT1 showed the highest reduction in waist circumference at 9 months (mean difference = -11.5 cm, P < 0.001) and 24 months (mean difference = -8.8 cm, P < 0.001). Both fasting and 2-h insulin values improved in the intervention groups compared with CON. A significant decrease in 2-h insulin values from baseline was found in CWT1 and CWT2. Matsuda index improved in the CWT1 group from the baseline to 24 months (2.03, P = 0.025). The most effective weight loss regimen is a combination of iBM and weight training introduced from the very beginning of the weight loss period. Treatment of morbid obesity should include an intensive start with exercise and diet regardless of weight status.

Effects of resistance training method on body composition, isokinetic strength and endurance, cardiopulmonary function, anaerobic power in female judo players

Purpose The purpose of this study was to investigate the effects of training methods on body composition, isokinetic strength and muscle endurance, cardiopulmonary function, and anaerobic power in female judo players. Methods Subjects performed weight training (n=10) and circuit weight training (n=10) consisting of 10 sports items for 12 weeks. In order to analyze the effects of training, body composition, isokinetic strength and muscle endurance, cardiopulmonary function, and anaerobic power were measured and the effect of training was verified. Results First, the comparison of body composition between WT and CWT groups showed that significant interaction effect between group and period was found in all variables (weight: F=1082.694, p=.001, body fat mass F=199.999, p=.001; skeletal muscle mass F=2481.698, p=.001, and percentage body fat: F=496.246, p=.001). Second, there was a significant interaction effect between group and duration in shoulder muscle strength and knee endurance (EPTL: F=6.598, p=.019; EAPL: F=12.860, p=.002). Conclusions The result of this study showed that the interaction effect between period and group was not significant according to the training method but the overall effect of the circuit weight training group was more positive than the weight training group. Therefore, it can be concluded that the 12 weeks circuit weight training can contribute to improve the performance of female Judo players by improving body composition, strength and muscle endurance, cardiopulmonary function and anaerobic power.

Comparative Study of Aerobic Exercise and Weight training on Metabolic Syndrome among Breast Cancer Survivors

Introduction: Breast cancer is the most frequent-occurring cancer among women and the leading cause deaths. Despite this Breast cancer treatments still have side effects that may negatively impact recovery and quality of life (QOL) after initial treatments. BCRL is a chronic swelling of the arm, hand and associated trunk quadrant. It usually develops after damage to the axillary lymph nodes due to breast cancer therapies. Methods: Participants who had fulfilled the eligibility criteria were randomized to either the aerobic exercise group (n = 20) and weight training group (n = 20). Exercise program was divided into a warm-up period, moderate intensity of aerobic exercises, and cool-down period. Weight-training exercise of low to moderate intensity with relatively slow progression significantly improved the upper limb strength, lower limb strength and incidence of breast cancer-related lymphoedema. Outcomes were assessed at baseline and post intervention. Results: Outcome were assessed by the functional assessment of cancer therapy-breast (FACT-B) scale and 6 min walk test (6MWT) Depressive symptoms are assessed using the CES-D scale. Upper limb musculoskeletal disorders is assessed using the DASH (Disabilities of the Arm, Shoulder, and Hand) The results confirmed the hypothesis that 12 week of moderate-intensity aerobic exercise program significantly reduces BCRL. Conclusion: There have been many studies of resistance exercise in breast cancer survivors, Findings of this trial revels that aerobic exercise will contribute to the reduction of metabolic syndrome in best cancer survivors.
