“…It is difficult to make comparisons across studies due to numerous reasons. Firstly, the degree of COD were different, with Rydså and van den Tillaar (2020) reporting greater differences between interventions with the 90° turn compared to the 45° cut, which leads to the speculation that the larger the COD angle, the higher the overload of the WR. Secondly, the subjects used in the previous studies have both used male soccer athletes, whereas this study has used female netball athletes.…”

“…One group of researchers investigated the acute effects of wearing 5% BM weighted vest; however, this was during a 45° cutting movement in male soccer athletes, with no significant differences reported (Li et al., 2020). Another research group investigated the acute effects of 1% body mass per leg attached to the shank and thigh during a 45° (cut) and 90° (turn) COD performance in male soccer athletes (Rydså & van den Tillaar, 2020). They reported significant total time differences ( p < 0.05) in both shank and thigh loaded conditions compared to unloaded, with the shank loaded protocol resulting in slower, yet not significant, total times compared to thigh loading.…”

“…The authors reported a large effect for different WR placements (ES = 1.4-2.0), with shank loading producing a longer total time and split times compared to thigh loading across all loading strategies. The largest total time significant (p < 0.05) difference was reported for 3% and 5% of body mass loading for shank and thigh, respectively (Rydså, 2020). Li et al (2020), investigated the acute effects to COD performance during a 45°cut maneuver, in male soccer athletes, when an additional 5% body mass was attached to the torso.…”

“…Previously, different training methods have been used in an attempt to enhance COD performance (Rydså & van den Tillaar, 2020). The most commonly used training methods are plyometric (ES = 0.60–3.50) (Asadi et al., 2016; Bogdanis et al., 2019; Jlid et al., 2019), traditional resistance (ES = 0.26–1.94) (Arazi et al., 2014; Hammami et al., 2017; Keller, Koob, Corak, von Schöning, & Born, 2020) and combination training (ES = 0.41–0.66) (Faigenbaum et al., 2007; Ramirez‐Campillo et al., 2018).…”

The aim of this study was to determine the acute effects of wearable resistance forearm (WRf) loading versus shank (WRs) loading on change of direction (COD) performance in netball athletes. Ten elite female netball athletes (age: 24.9 ± 5.0 years, height: 180.1 ± 6.5 cm, weight: 81.3 ± 15.0 kg) participated in this within‐subject repeated measures study under three conditions: (1) no load (NL), (2) WRs and (3) WRf, both wearable resistance conditions loaded with 1% body mass on each limb. Athletes performed a modified 5‐0‐5 COD test with additional timing splits and inertial measurement units placed in their shoes. Total time was significantly longer for both WR conditions with a small effect compared to NL (p < 0.05, ES = 0.22–0.25). The greatest differences between WRs and WRf as compared to NL were in the acceleration phase with moderate effect sizes (0–2 m) (p < 0.05, ES = −0.67–0.79). Both loading conditions had moderate to large significant effects on peak deceleration (ES = 0.56–0.82) and maximum speed (ES = −0.50–0.60). No significant differences were observed between WR conditions. It appeared that WRs and WRs acutely affected COD performance and therefore might provide a potential training stimulus to elicit positive COD performance adaptations if used over an extended period of time. The choice of overload depended on the musculature that needed training.

Background Soccer players often wear light-weighted wearable resistance (WR) attached to different body parts during the warm-up period with the aim to improve measures of physical fitness. However, the effect of WR on physical performance is unknown. This study evaluated the effects of WR with different micro-loadings on repeated change-of-direction (RCoD) performance while executing small-sided soccer games (SSG). Methods Twenty male soccer players aged 16.0 ± 1.5 years (body mass 74.0 ± 7.4 kg, body-height 175.0 ± 10.0 cm) volunteered to participate in this study. Following a within-subject study design, players performed four specific warm-up protocols in randomized order with a rest of 72 h between protocols: (1) WR micro-loadings with 0.1% of body mass (WR0.1); (2) WR micro-loadings with 0.2% of body mass (WR0.2); (3) WR micro-loadings with 0.3% of body mass (WR0.3); (4) no WR (control = CONT). After the warm-up protocols, players performed 2 sets of 20-min SSG. The RCoD was collected at the 8th min of SSG (SSG 1–8 min), the 15th min of SSG1 (SSG1-15 min), and at the 15th min of SSG2 (SSG2-15 min). Outcomes included mean and total RCoD indices (i.e., mean time and total time for each condition). Results Based on the outcomes of a two-way repeated measures analysis of variance (ANOVA), WR0.1 and WR0.2 were more effective than control in dampening the decrease of RCoD’s total time during SSG1-8 min, and SSG2-15 min (small ES: 0.24–0.35; p < 0.05). However, no significant differences were observed between WR0.3 and control. In addition, WR0.1 and WR0.2 significantly affected the decreases in RCoD’s mean best time during SSG1 and SSG2 which was observed in the unloaded condition (CONT) and consequently displayed a lower rate of RCoD performance decrease. Conclusion This study reports that wearing lower extremity WRs with micro-loads of 0.1% or 0.2% of body mass attenuates physical fatigue indicated in attenuated RCoD performance while executing SSG.

The aim of this study is to investigate the effects of plyometric training with additional weight on physical performance and muscle damage findings in faculty of sports sciences athlete-students. Physical performance tests and blood samples of the athlete-students (male 23.41 ± 3.2 years old) were collected both from sample and the control groups at the first week of the study and at the last training of the twelfth week. During the study, plyometric training programs were applied to the additional weight group (AWG) and no additional weight group (AG). By the end of first and twelfth week, players’ BMI and body fat percentage tests were applied together with the physical tests of shuttle, yoyo, vertical jump, horizontal jump, agility and sprint performance tests. Blood samples were also taken to check muscle damage control markers (CK and LDH). Results: According to the results of tests performed at the end of first and twelfth weeks’ plyometric trainings on group with additional weight group (AWG), shuttle, yoyo and horizontal jumping were found to be significantly increased, while sprint performance, BMI and body fat performance tests were significantly decreased. The test results of the group without additional weight (AG) was; significant increase in shuttle, yoyo and vertical jump while significant decrease in sprint performance and fat %. By the end of twelve week plyometric trainings, no muscle damage has been observed in (AWG), CK pre-training (229,00 ± 155,25) and post training values (242,33 ± 193,67) and LDH pre-training (169,75 ± 40,85) and post-training (174,33 ± 39,12) values. As a result of the study, 12-week plyometric training with additional weight applied to football athletes-students not only increased their physical performance, but also muscle damage (CK and LDH) was not observed.
