ABSTRACT

Objectives: The purpose of this study was to investigate if there is a relation between hamstring tightness and lumbar lordosis as well as trunk flexibility based on gender differences and to analyze the differences in hamstring tightness, lumber lordosis and trunk flexibility in healthy adults. Methods: One hundred young healthy adults were recruited and distributed into 2 equal groups according to gender: group A (female group) and group B (male group). Hamstring tightness (HT) was measured by Active Knee Extension (AKE) test and Straight Leg Raise (SLR) test, the angle of lumbar lordosis was measured with a flexible ruler from standing position and trunk flexion flexibility (TFF) was measured by Fingertip-to-Floor Test. Results: There was a significant correlation between TFF and both measures of HT (SLR, p = 0.001; AKE, p = 0.001) in females. While, there was a non-significant correlation in males (SLR, p = 0.900; AKE, p = 0.717). Moreover, there was a non-significant correlation between lumbar lordosis and HT measures in both groups as (p > 0.05). Furthermore, there were significant differences between males and females in hamstring flexibility, TFF and lumbar lordosis as (p < 0.05). Conclusion: Gender differences in the relationship between hamstring tightness and trunk flexion flexibility are significant. However, there was no significant difference between males and females in the relationship between hamstring tightness and lumbar lordosis.

ABSTRACT

BACKGROUND: Physical activity behavior change is considered one of the most challenging lifestyle modifications in patients with heart failure. Even after participation in a cardiac rehabilitation program, most patients do not engage in the recommended level of physical activity. OBJECTIVE: To determine which baseline demographic, physical activity levels, psychological distress, and clinical variables predicted physical activity behavior change to increasing light-to-vigorous physical activity by 10,000 steps/day following participation in home-based cardiac rehabilitation intervention. METHODS: A prospective design involving secondary analysis was used to analyze data obtained from 127 patients (mean, 61; range, 45-69 years) enrolled in and completed an 8-week home-based mobile health app intervention. The intervention was designed to encourage health behavior change with regard to decreasing sedentary behavior and increasing physical activities performed at light or greater intensities. RESULTS: None of the participants accumulated 10,000 steps or more per day pre-intervention (mean, 1549; range, 318-4915 steps/day). Only 55 participants (43%) achieved an average daily step count of 10,000 or more at week 8 of the intervention (10,674 ± 263). The results of the logistic regression showed that higher pre-intervention physical activity levels and anxiety symptoms and lower depressive symptoms were associated with a higher likelihood of achieving physical activity behavior change (p < .003). CONCLUSION: These data highlight that determining pre-intervention physical activity levels and depressive symptoms can be the key to designing an effective home-based cardiac rehabilitation intervention in patients with heart failure.
