Strength training often combines closed-kinetic-chain exercises (CKCEs) and open kinetic-chain exercises (OKCEs). The CKCE may be more effective for improving performance in lower-body training. Recently, we reported upper-body CKCE (using a commercially available system of ropes and slings) was as effective as OKCE training for strength gains and that CKCE was more effective than OKCE for improving throwing performance. To our knowledge the effectiveness of a strength training program that uses exclusively CKCE is unknown. In this study, we examined the effectiveness of CKCE vs. OKCE strength training programs in women enrolled in an introductory strength training program. Twenty-six participants were randomized to OKCE (traditional exercises) or CKCE (sling-based exercises). Participants completed 6 sets per week for 13 weeks. Pre and posttraining evaluations included the following: 1 repetition maximum (1RM) leg and bench press; sling exercise push-ups; isokinetic dynamometry; lateral step-down test; and the Star Excursion Balance Test. Both groups significantly improved bench press (by an average of 4-6 kg) and leg press (by an average of 23-35 kg) (p < 0.001). There was a significant group × time interaction (p < 0.001) for sling exercise push-ups (OKCE pre = 5.5 ± 8.6, OKCE post = 6.1 ± 8.2, CKCE pre = 6.8 ± 6.0, CKCE post = 16.9 ± 6.6). Isokinetic measures of knee extension, knee flexion, shoulder internal rotation, and shoulder external rotation increased (improvements ranged from 2.7 to 27.7%), with no group differences. Both OKCE and CKCE strength training elicited similar changes in balance. We conclude that CKCE training is equally as effective as OKCE training during the initial phases of a strength training program in women. The fact that only CKCE improved sling exercise push-ups supports previous findings suggesting functional superiority of CKCE.[/et_pb_accordion_item][et_pb_accordion_item title="2011 - Effect of Core Stability Training on Throwing Velocity in Female Handball Players (Saeterbakken A, van den Tillaar R, Seiler S)" _builder_version="3.0.105" open="off"]Saeterbakken, AH, van den Tillaar, R, and Seiler, S. Effect of core stability training on throwing velocity in female handball players. J Strength Cond Res 25(3): 712-718, 2011-The purpose was to study the effect of a sling exercise training (SET)-based core stability program on maximal throwing velocity among female handball players. Twenty-four female high-school handball players (16.6 ± 0.3 years, 63 ± 6 kg, and 169 ± 7 cm) participated and were initially divided into a SET training group (n = 14) and a control group (CON, n = 10). Both groups performed their regular handball training for 6 weeks. In addition, twice a week, the SET group performed a progressive core stability-training program consisting of 6 unstable closed kinetic chain exercises. Maximal throwing velocity was measured before and after the training period using photocells. Maximal throwing velocity significantly increased 4.9% from 17.9 ± 0.5 to 18.8 ± 0.4 m·s?1 in the SET group after the training period (p < 0.01), but was unchanged in the control group (17.1 ± 0.4 vs. 16.9 ± 0.4 m·s?1). These results suggest that core stability training using unstable, closed kinetic chain movements can significantly improve maximal throwing velocity. A stronger and more stable lumbopelvic-hip complex may contribute to higher rotational velocity in multisegmental movements. Strength coaches can incorporate exercises exposing the joints for destabilization force during training in closed kinetic chain exercises. This may encourage an effective neuromuscular pattern and increase force production and can improve a highly specific performance task such as throwing.[/et_pb_accordion_item][et_pb_accordion_item title="2010 - Discussion on Suspension Training in Application to Basketball (Li W, Cao J)" _builder_version="3.0.105" open="off"]ecently,the core strength training has aroused in basketball.This paper analyzes the suspension training methods on physical training to improve the basketball players‘ physical quality and skills.[/et_pb_accordion_item][et_pb_accordion_item title="2010 - Motor Control Exercises, Sling Exercises, and General Exercises for Patients with Chronic Low Back Pain: A Randomized Controlled Trial With 1-Year Follow-up (Unsgaard-Tøndel M,Fladmark AM, Salvesen Ø, Vasseljen)" _builder_version="3.0.105" open="off"]The postintervention assessment showed no significant differences among groups with respect to pain (overall group difference) or any of the outcome measures.

It is to explore the effect of different training methods of sling exercise therapy on neck pain,39 female neck pain university students voluntarily attend this study and are randomly assigned into control group,active movement group and stability muscle training group.Wong-Baker pain scale scores and the muscles‘ scalability,flexibility,stiffness of neck are used to descript the effect of pre-and post-sling exercise therapy.The active movement group and stability muscle training group show effectively decreasing in the Wong-Baker pain scale scores after once interference,and keeps it 5 days and 3 days,respectively.The scalability of muscles,flexibility,and stiffness improvement is not obvious;No significantly positive correlation are found among the trapezius muscles‘ scalability,flexibility,stiffness in affected area and Wong-Baker pain scale score.We propose active movement and the stability of the neck muscle training as a means of neck discomfort therapy,treatment frequency is once a week and twice a week.
