Muscle strength, functional endurance and health related quality of life in active older female golfers
No full textBackground: Grip strength is a reliable predictor of whole body strength in older adults, but muscle characteristics of people with different activity levels have not been studied previously. The present study examined the relationship between grip strength (GS), quadriceps peak torque (QPT), functional endurance, and health-related quality of life (HRQoL) in older female golfers.
Methods: Twenty-nine healthy female golfers (mean age 69.1 years, SD 3.4) participated. The ISOCOM and JAMAR dynamometers were used to assess QPT and GS, respectively. Functional endurance tests included 1-min sit-to-stand test (1MSTS), 30-s wall press (30SWP), and 2-min stair climb (2MSC). HRQol was assessed using the SF-36 questionnaire.
Results: Mean GS and QPT were 27.5 ± 4 kg/f and 103.7 ± 25.1 N m, respectively. Mean scores for the 1MSTS, 30SWP, and 2MSC were 31 ± 7.7, 17.4 ± 3.5, and 237.5 ± 48.6 repetitions, respectively. GS was moderately correlated with QPT (r = 0.44), 1MSTS (r = 0.36), and 2MSC (r = 0.36), but had weak correlation with 30SWP (r = 0.003). Moderate correlation was observed between quadriceps peak torque and the 1MSTS (r = 0.50; p = 0.01), 2MSC (r = 0.44; p = 0.02) and 30SWP (r = 0.33). 30SWP and 2MSC had moderate correlations with PF r = 0.41 (p = 0.03) and r = 0.61 (p < 0.0005) and general physical well-being r = 0.47 (p = 0.01) and r = 0.39 (p = 0.04), respectively.
Conclusion: Quadriceps strength was more closely associated with functional endurance than grip strength. A single strength measure may not reflect overall muscle characteristics in active older females, and hence, assessment of both upper and lower limb strengths may be appropriate

No full textQuadriceps muscle tone, elasticity and stiffness in older males: reliability and symmetry using the MyotonPRO
No full textBackgroundThe MyotonPRO (Myoton Ltd; London) is a new portable device for measuring muscle mechanical properties (e.g. tone) and its reliability has yet to be established. Little is known about between-limb symmetry of mechanical properties in healthy older people, despite symmetry often being used as a measure of unilateral abnormalities in clinical assessment. Since quadriceps is important for mobility, it was selected for the present study.AimsTo investigate: (i) between-day intra-rater reliability of a novice user of MyotonPRO; (ii) between-side symmetry of mechanical properties of quadriceps in older males.MethodsTwenty healthy, community dwelling, right-lower-limb-dominant males (mean age 71.7, range 65–82 years) were studied. With the participant in relaxed supine lying, the MyotonPRO applied two consecutive sets of 10 taps to induce muscle oscillations of rectus femoris, from which measurements of decrement (elasticity), frequency (tone), and stiffness were obtained. Tests were performed on two occasions at the same time and day of the week, one week apart.ResultsRepeated measurements had very high within-day (intraclass correlation coefficient, ICC 3,1 > 0.90) and high between-day (ICC 3,2 > 0.70; mean of two measurement sets) reliability. There was no statistically significant difference between muscle mechanical properties of the dominant and non-dominant muscles (<2.5% difference; p > 0.05), thereby indicating symmetry.ConclusionsHigh intra-rater reliability was established for MyotonPRO measurements of quadriceps in healthy older males, which were symmetrical between sides. These findings indicate that larger studies are warranted to establish normal reference ranges of data with which to compare patients with muscle abnormalities.<br/
Materials to re-create Low-mode near-inertial wave generation
No full textThere are two folders (compressed in .zip format). Each folder has an associated plain-text documentation file that includes detailed information about its contents. The folders are: (1) modeling scripts and (2) plotting_scripts. The first folder includes all Matlab scripts and functions necessary to reproduce the model results from scratch. The second folder contains Matlab scripts and functions to re-create the figures included in Stokes et al. (2025). All of the data needed for these scripts are included in the folder.A recent manuscript examined the generation of low-mode near-inertial waves in the ocean using a modified shallow water model. This submission includes the Matlab functions to configure, generate, and post-process the model output.

Handgrip and quadriceps muscle endurance testing in young adults
No full textBackground: grip strength is widely used for estimating whole body strength but there is a lack of information relating to grip endurance. Comparison between endurance of different muscle groups has received little attention. The main aim of the present study was to determine the endurance characteristics of hand grip and quadriceps muscles in healthy young adults and then to examine the association between fatigability of the two muscle groups.Methods: twenty one healthy participants (8 males and 13 females) aged 18–35 years were studied. A maximal intermittent endurance test, consisting of 12 isometric contractions held for 3 seconds separated by 5 second rest periods, was utilised to measure muscle endurance. A Biodex isokinetic dynamometer and Jamar dynamometer were used to assess quadriceps and hand grip respectively. The mean of first (M1) and last (M2) three repetitions was calculated. Fatigue index values were calculated for both muscle groups by the 1st peak torque (PT) minus the last (12th) PT, divided by the 1st PT multiplied by 100.Results: quadriceps torque (M1:197.3 ± 65.2 Nm; M2:163.1 ± 47.6 Nm) and grip strength (M1:33.6 ± 9.9 Kg; M2:25.2 ± 8.1 Kg) both declined significantly during the 12 repetitions (p < 0.05). Hand grip showed a significantly higher mean fatigue index of 30% compared to 18% in the quadriceps (p < 0.05).Conclusions: quadriceps showed better fatigability than hand grip. The findings therefore indicate caution against using grip endurance as a surrogate measure of quadriceps endurance. Further research is warranted to confirm observed differences between genders and to study endurance in different age groups<br/
