Purpose. This study was aimed at comparing the effects of TheraBand and theratube eccentric exercises on quadriceps muscle strength in young adults. Methods. Thirty young adults (19 females, 11 males) participated in this pretest-posttest experimental study. Participants were randomly assigned to one of the two groups: TheraBand and theratube groups. They received the training intervention 3 times a week for 4 weeks (12 sessions) with progression after 2 weeks. Maximum eccentric quadriceps strength was assessed using the Biodex isokinetic dynamometer system. Additionally, quadriceps muscle mass was measured using a tape. Results. Both groups showed a significant improvement in the peak torque of the eccentric isokinetic quadriceps’ strength after weeks 2 and 4. Strength change in the quadriceps was nonsignificant in the theratube group compared to the TheraBand group after 4 weeks of training ( p < 0.05 ). There was no increase in muscle mass during the 4 weeks of training in any group ( p > 0.05 ). Conclusion. Both the TheraBand and theratube are equally effective in the strengthening of the quadriceps muscle in young adults. Therefore, either the TheraBand or theratube may be used according to the availability and feasibility of the subjects for training intervention.

Background Muscle force testing is one of the more common categories of diagnostic tests used in clinical practice. Clinicians have little evidence to guide interpretations of muscle force tests when pain is elicited during testing. Objective The purpose of this study was to examine the construct validity of isometric quadriceps muscle strength tests by determining whether the relationship between maximal isometric quadriceps muscle strength and functional status was influenced by pain during isometric testing. Design A cross-sectional design was used. Methods Data from the Osteoarthritis Initiative were used to identify 1,344 people with unilateral knee pain and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale scores of 1 or higher on the involved side. Measurements of maximal isometric quadriceps strength and ratings of pain during isometric testing were collected. Outcome variables were WOMAC physical function subscale, 20-m walk test, 400-m walk test, and a repeated chair stand test. Multiple regression models were used to determine whether pain during testing modified or confounded the relationship between strength and functional status. Results Pearson r correlations among the isometric quadriceps strength measures and the 4 outcome measures ranged from −.36 (95% confidence interval=−.41, −.31) for repeated chair stands to .36 (95% confidence interval=.31, .41) for the 20-m walk test. In the final analyses, neither effect modification nor confounding was found for the repeated chair stand test, the 20-m walk test, the 400-m walk test, or the WOMAC physical function subscale. Moderate or severe pain during testing was weakly associated with reduced strength, but mild pain was not. Limitations The disease spectrum was skewed toward mild or moderate symptoms, and the pain measurement scale used during muscle force testing was not ideal. Conclusions Given that the spectrum of the sample was skewed toward mild or moderate symptoms and disease, the data suggest that isometric quadriceps muscle strength tests maintain their relationship with self-report or performance-based disability measures even when pain is elicited during testing.

Increased Risk

Background: Distance running is a popular interscholastic sport, but also has an associated high risk of running-related injuries. Recent literature suggests that functional tests may help to identify athletes at increased risk of injury. The Y-Balance Test (YBT) is an objective measure used to assess functional muscle strength and balance and to expose asymmetries between tested limbs. Purpose: To determine if YBT performance was associated with maturation status in healthy, youth distance runners. We hypothesized that mid-pubertal (MP) runners would demonstrate less functional reach distance than pre-pubertal (PrP) or post-pubertal (PoP) runners. Methods: A convenience sample of 142 (Females: n=79, Males: n=63) uninjured youth runners (ages 13.5±2.7 years; weekly running distance: 18.2±20.4 km) were recruited from the local community. All runners met inclusion criteria, indicating that they were between 9 and 19 years old and participated in long-distance running activities such as school/club track and field, cross country, road races, trail running, and/or soccer. The runners completed a modified Pubertal Maturational Observation Scale (PMOS), then were screened for right (R) and left (L) anterior (ANT), posteromedial (PM) and posterolateral (PL) reach distances (cm) normalized by lower limb length (cm). Composite reach distance was calculated by the sum of the three reach distances divided by three times the limb length multiplied by 100 for R and L limbs. ANOVA with Bonferroni post hoc tests were used to compare maximum normalized reach distances for the three directions and composite reach distance by maturation status and sex. Results: Overall, 31.7% were classified as PrP status, 26.1% as MP, and 42.3% as PoP, with similar percentages by sex ( p=0.84). The only significant mean difference was found for R ANT maximum normalized reach distance between PrP and PoP ( p=0.02), indicating a greater normalized reach in PrP athletes. No significant mean differences were found for R or L PM and PL maximum normalized reach distances, or for R or L composite reach distances, by maturation status or when stratified by maturation and sex ( p>0.05). Conclusions: In this sample of youth runners, the YBT was only a discriminator of anterior reach distance between pre-pubertal and post-pubertal runners. As decreased anterior reach is associated with reduced quadriceps muscle strength and anterior knee pain, reduced anterior reach in post-pubertal runners may potentially signify an increased risk of sustaining a running-related injury. Thus, preventive efforts to ensure good functional quadriceps muscle strength may be merited.
