Effects of High-Intensity Interval Training With Specific Techniques on Jumping Ability and Change of Direction Speed in Karate Athletes: An Inter-individual Analysis

Effects of high-intensity training on jumping performance among athletes: a systematic review with meta-analysis

This review aims to conduct a meta-analysis of the impact of high-intensity training (HIT) on athlete jumping performance. As of May 2024, we conducted a comprehensive search on PubMed, Web of Science, SCOPUS, and EBSCOhost databases in accordance with the PRISMA guidelines. Use the PEDro scale to evaluate the methodological quality of the included study. Meta-analysis of random effects model calculations. Conduct subgroup analysis (participant age, gender, training experience, intervention length and frequency). 18 high-quality studies met the inclusion criteria, including 490 athletes aged between 6 and 27 years old. The results showed that high-intensity interval training (HIIT) has a moderate effect on athlete jumping performance (ES = 0.918), while high-intensity functional training (HIFT) has a small effect on athlete jumping performance (ES = 0.581). The sub analysis of moderating variables includes 19 datasets. Compared with the control group, HIT has a positive impact on the jumping performance of athletes. The training experience, age, gender, intervention frequency, and intervention length of participants did not have a significant impact on the jumping performance of athletes, indicating the applicability of HIT as a training method. However, more extensive exercise experiments are needed to obtain stronger evidence.

Effect of a Six Week In-Season Training Program on Wrestling-Specific Competitive Performance

The effect of multi-component training on specific performance is under-researched in wrestlers. The aim of this study was to determine the effect of six weeks of multi-component training on The Special Wrestling Fitness Test (SWFT) performances of wrestlers who were preparing for an international championship, and to, additionally, determine their inter-individual adaptive variability. The wrestlers (n = 13; 7 females; all international level) underwent technical-tactical and physical fitness training for the six weeks before the championship, 12 sessions per week (i.e., 36 h per week). Before and after the intervention the athletes were assessed with the SWFT, a wrestling-specific competitive performance test that includes measurements for throws, heart rate response to the SWFT, and the SWFT index. Significant pre–post intervention improvements were noted for throws (pre = 23.5 ± 2.9; post = 24.9 ± 3.6; p = 0.022) and SWFT_index (pre = 14.9 ± 2.2; post = 14.1 ± 2.2; p = 0.013. In conclusion, six weeks of multi-component training improved wrestling-specific competitive performances in highly-trained wrestlers, although with a meaningful inter-subject variability.
