scholarly journals The Acute Effects of Cluster Set during Complex Training on Countermovement Jump

This study aims to determine the acute effects of complex training with a cluster set configuration on countermovement jump. A crossover counterbalance design was used in this study. Fourteen recreational male underwent three sessions of trainings, with a minimum of 72 hours between each session. In the complex training (CT) protocol, squats with 65% 1RM were used for resistance training while jump squats with 80% of maximum effort for plyometric. Subjects performed the resistance and plyometric training alternately, using either traditional (TRA) or cluster with two sets (CS2). In TRA, no rest was given between the repetitions until they completed the entire set. For CS2, the pairs of CT 30s rest were inserted between the repetitions. The results of the study showed no significant interaction between TRA and CS2 across the all parameters: CMJ height (p> 0.05), power (p>0.050, and velocity (p>0.05) respectively. This study shows that both TRA and CS2 provide better CMJ height, power and velocity during CT. In conclusion, both TRA and CS2 can be adopted in training to enhance power.

Purpose. To compare the acute effects of two post activation potentiation (PAP) protocols using traditional or cluster-set configurations on countermovement jump (CMJ) performance. Methods. Twenty-six male basketball players were evaluated on three occasions separated by 72 hours. On the first session, athletes performed barbell squat jumps with progressively heavier loads to determine their individual optimum power loads. On the second and third sessions, athletes completed two PAP protocols in a randomized, counterbalanced order: 3 sets of 6 repetitions of squat jumps using optimum power loads performed with either a traditional (no inter-repetition rest) or a cluster-set (20 s rest every 2 repetitions) configurations. After a comprehensive warm-up, CMJ height was measured using a force platform before, 30 s, 4 min, and 8 min after completing the PAP protocols. Results. While at post-30 s athletes jumped lower compared to baseline in both conditions, jump heights were 0.71 cm higher following the cluster-set compared to the traditional condition (95% CI: 0.37, 1.05 cm). While athletes jumped higher compared to baseline at post-4 and post-8 min in both conditioning, jump heights were higher following the cluster-set compared to the traditional condition in post-4 min by 1.33 cm (95% CI: 1.02, 1.65 cm) and in post-8 min by 1.64 cm (95% CI: 1.41, 1.88 cm). Conclusions. Both traditional and cluster-set configurations induced a PAP response in vertical jump performance using optimum power loaded squat jumps, but the cluster-set configuration led to superior performance likely due to the reduced accumulation of muscular fatigue.

This study examined the acute effects of resistance training (RT) on volleyball-specific performance. Sixteen female volleyball players undertook their initial, pre-season RT bout. Countermovement jump (CMJ), delayed onset of muscle soreness (DOMS), and sport-specific performances (i.e., run-up jump, agility, and spiking speed and accuracy) were measured before, 24 (T24), and 48 (T48) hours after RT. A significant increase in DOMS was observed at T24 and T48 (~207.6% ± 119.3%; p < 0.05; ES = 1.8 (95% CI: 0.94–2.57)), whilst agility was significantly impaired at T48 (1.7% ± 2.5%; p < 0.05; ES = 0.30 (95% CI: −0.99–0.40)). However, there were no differences in CMJ (~−2.21% ± 7.6%; p > 0.05; ES = −0.11 (95% CI: −0.80–0.58)) and run-up jump (~−1.4% ± 4.7%; p > 0.05; ES = −0.07 (95% CI: −0.76–0.63)). Spiking speed was significantly reduced (−3.5% ± 4.4%; p < 0.05; ES = −0.28 (95% CI: −0.43–0.97)), although accuracy was improved (38.3% ± 81.4%: p < 0.05) at T48. Thus, the initial, preseason RT bout compromised agility and spiking speed for several days post-exercise. Conversely, spiking accuracy improved, suggesting a speed–accuracy trade-off. Nonetheless, at least a 48-h recovery may be necessary after the initial RT bout for athletes returning from the off-season or injury.

The aim of the study was to determine the effects of short-term (4 weeks, twice a week: 8 sessions) plyometric training on agility, jump, and repeated sprint performance in female soccer players. The study comprised 17 females performing this sports discipline. The players were randomly divided into two groups: with plyometric training (PLY) and the control (CON). All players followed the same training program, but the PLY group also performed plyometric exercises. Tests used to evaluate physical performance were carried out immediately before and after PLY. After implementing the short PLY training, significant improvement in jump performance (squat jump: p = 0.04, ES = 0.48, countermovement jump: p = 0.009, ES = 0.42) and agility (p = 0.003, ES = 0.7) was noted in the PLY group. In the CON group, no significant (p > 0.05) changes in physical performance were observed. In contrast, PLY did not improve repeated sprint performance (p > 0.05) among female soccer players. In our research, it was shown that PLY can also be effective when performed for only 4 weeks instead of the 6–12 weeks typically applied.

Abstract Background: Symptom burden remains a critical concern for individuals with non-small cell lung cancer (NSCLC) following the completion of treatment. The most common symptom clusters, dyspnea (shortness of breath) and fatigue,can contribute to physical decline, reductions in quality of life, and a higher risk of comorbidities and mortality. Dyspnea is a primary limiter of exercise capacity in individuals with lung cancer, resulting in exercise avoidance and an accelerated physical decline. As such, designing resistance training with cluster sets to mitigate symptoms of dyspnea and fatigue may result in improved exercise tolerance. Thus, maintainingthe exercise stimulus via cluster sets, combined with improved tolerance of the exercise, could result in maintenance of physical function and quality of life. The purpose of this study is to investigate the feasibility and preliminary efficacy of a hybrid-delivery home-based cluster-set resistance training program in individuals with NSCLC. Methods: Individuals with NSCLC (n=15), within 12-months of completion of treatment will be recruited to participate in this single arm feasibility trial. Participants will complete 8-weeks of home-based resistance training designed to minimizedyspnea and fatigue. The hybrid-delivery of the program will include supervised sessions in the participants’ home, and virtual supervision via video conferencing. The primary outcome of feasibility will be quantifiedby recruitment rates, retention, acceptability, and intervention fidelity. Exploratory outcomes (dyspnea, fatigue, quality of life, physical function, and body composition) will be assessed pre- and post- intervention. Discussion: This study will provide important data on the feasibility of delivering this intervention and inform procedures for a future randomized controlled trial.

The purpose of this study was to investigate the effects of plyometric and cluster resistance training on explosive power and maximum strength in karate players. Eighteen women, karate players (age mean ± SD 18.22 ± 3.02 years, mean height 163 ± 0.63cm, and mean body mass 53.25 ± 7.34 kg) were selected as volunteer samples. They were divided into two groups with respect to their recorded one repetition maximum squat exercise: [1] plyometric training (PT=9) and [2] Cluster training (CT=9) groups and performed a 9-week resistance training protocol that included three stages; [1] General fitness (2 weeks), [2] Strength (4 weeks) and [3] Power (3 weeks). Each group performed strength and power trainings for 7 weeks in stage two and three with owned protocol. The subjects were evaluated three times before stage one and after two and three stages for maximum strength and power. Data was analyzed using two way Repeated Measures (ANOVA) at a significance level of (P≤0.05). The statistical analysis showed that training stages on all research variables had a significant impact. The maximum strength of the pre-test, post-test strength and post-test power were in cluster group: 29.05 ± 1.54; 32.89 ± 2.80 and 48.74 ± 4.33w and in plyometric group were 26.98 ± 1.54; 38.48 ± 2.80 and 49.82 ± 4.33w respectively. The explosive power of the pre-test, post-test strength and post-test power in cluster group were 359.32±36.20; 427.91±34.56 and 460.55±36.80w and in plyometric group were 333.90±36.20; 400.33±34.56 and 465.20±36.80w respectively. However, there were not statistically significant differences in research variables between resistance cluster and plyometric training groups after 7 weeks. The results indicated both cluster and plyometric training program seems to improve physical fitness elements at the same levels.
