Effects of Lumbar Resistance and Stabilization Complex Exercises on Extremity Muscle Strength and Endurance of Normal Adults

Abstract

Abstract.[Purpose] The purpose of this study was to examine the effects of lumbar resistance and stabilization complex exercises on upper/lower extremity muscle strength and endurance of the general adult population. [Subjects] Fourteen male adults in their 20s participated. Seven persons each were randomly assigned to a resistance exercise group (REG) or a resistance and stabilization exercise group (RSEG). Exercise programs were implemented three times a week for 50 minutes for eight weeks.[Methods] The Biodex System 3 Pro was used to measure the upper/lower extremity muscle strength and endurance of the REG and RSEG prior to the intervention and at four and eight weeks following the commencement of the intervention. The results were then compared and analyzed.[Results] With regards to changes in upper/lower extremity muscle strength and endurance, both groups showed significant increases during the experimental period. The two groups also exhibited differences in muscle strength during upper/lower extremity flexion and differences in muscle endurance during upper extremity extension and lower extremity flexion.[Conclusion] Lumbar resistance and stabilization complex exercises positively affected both upper and lower extremity muscle strength and endurance. In particular, the RSEG showed larger effects than the REG. Therefore, the resistance and stabilization complex training exercises appear to be more effective for rehabilitation of the upper/lower extremities.

Effects of specific muscle imbalance improvement training on the balance ability in elite fencers

“…Rippetoe (2000) also argued that explosive multijoint, core strength, and resistance exercises were necessary for effective strength and conditioning of fencing athletes 15 ) . Based on prior research, the present research, taking into account the normal exercises executed by national athletes, used flexibility, Pilates, and muscle balance exercises for 12 weeks to improve imbalance 16 , 17 ) . According to the results of this research, there was less mediolateral movement of the nondominant leg during the LOLS after the program than before the program.…”

The Usefulness of Performance Matrix Tests in Locomotor System Evaluation of Girls Attending a Ballet School — Preliminary Observation

“…Applying the Performance Matrix tests in functional assessment, as well as introducing an appropriate stabilization training, would undoubtedly contribute to the reduction of the presence of weak links in the motor systems of the students who took part in this research 15 , 21 , 22 , 23 , 24 ) . A strong “core” allows one to more effectively move the distal parts of the body 25 ) .…”

Multicenter survey analysis of satisfaction according to actual utilization of rehabilitation services

“…The velocity of the center of gravity and lower extremity joint moment are important factors for evaluation of STS motion, and are used to evaluate the effects of angular joint motion in a given direction during the entire cycle of performance of a linear motion by the body 11 ) . Studies of STS motion are largely conducted using three different methods: motion analysis based on kinematic systems; muscle activity pattern analysis based on electromyogram (EMG) signals; and methods that include kinetic analysis using force plates 12 ) . Among these, studies using electromyograms can measure how muscle energy supports the body against gravity, how muscles act to achieve targeted movements, and how much muscles rest in both healthy individuals and subjects with various diseases 13 ) .…”
