The Effect of Different Training Exercise of Endurance and Power on Legs and Core Muscle of Basketball Players with Low Back Pain. The aim of a study: to evaluate and compare different training methods on legs and core muscle power and endurance of basketball players with a low back pain. Study goals: To evaluate basketball players’ static endurance of core muscles, core flexor‘s and extensor‘s muscle force and endurance, knee flexor‘s and extensor‘s muscle force and endurance changes, compare functional status and determine correlation between lumbar mobility and pain intensity, functional parameters. Study methods. Thirty persons with low back pain by block randomization method was divided into two groups. Subjects of the control group used an exercise ball in physiotherapy procedures, experimental group subjects used suspension training system. The research was carried out at Vilnius University Hospital Santariskiu Klinikos Center for Rehabilitation, Physical and Sports Medicine from December of 2014 to March of 2016. Anthropometric data were collected, Self-reporting and observation was used for measuring pain intensity. The endurance levels of back and abdomen muscles, were ascertained after performing McGill‘s tests. Knee flexor and extensor, erector spinae and rectus abdominis muscle strength and endurance were evaluated by using isokinetic dynamometer Biodex System Pro 4. Results. The use of diverse kinezitherapic muscle strength training exercises for experimental and control groups patients with a low back pain indicates a statistically significant effect on: Static endurance of abdominal muscles in experimental group increased 115,2 sec., control group – 52,4 sec. Static endurance of back muscles in experimental group increased 54,60 sec. Static endurance of trunk muscles left side in experimental group increased by 15,74 sec., right side – 26,54 sec., control group left side – 13,8 sec., right side – 12 sec. Isokinetic unilateral extension of erector spinae in experimental group increased 72,22 N-M (p<0,05). Isokinetic unilateral flexion of rectus abdominis in experimental group increased 55,31 N-M. Isokinetic unilateral extension of erector spinae in experimental group increased 56,11 N-M, control group – 77,37 N-M. Isokinetic unilateral flexion of rectus abdominis in experimental group increased 47,9 N-M, control group – 30,94 N-M. Isokinetic right leg‘s knee in experimental group increased – 17,53 N-M. Isokinetic right leg‘s knee flexion in experimental group increased – 8,87 N-M, control group right leg – 9,22 N-M. Isokinetic right leg‘s knee extension in experimental group increased – 375,63 J, left leg – 289,33 J. Isokinetic right leg‘s knee flexion in experimental group increased – 207,72 J, left leg – 249,39 J. Pain intensity in experimental decreased – 3,5, control group – 3,07 score. Lumbar mobility in experimental group increased – 4,7 cm., control group – 3,2 cm. (p<0,05). Conclusions: Basketball players’ who exercised with suspension training system, significantly increased static back muscle endurance, core flexors and extensors muscle power rate at 120°/sec. and 60°/sec. angle speed, knee flexor and extensor muscle endurance, right leg‘s knee flexor and extensor muscle power. Basketball players of control group who exercised with an exercise ball, significantly increased core flexor and extensor muscle power, knee flexor muscle power at 60°/sec. angle speed. Both muscles strength – building techniques equally affected the changes in pain intensity and lumbar flexibility. Moderate and strong correlations were noticed in experimental group with lumbar mobility and core muscle static endurance, pain intensity, knee flexor extensor muscle power and force; pain intensity and knee flexor muscle power in experimental group, knee flexor and extensors muscle endurance in control group. |
