Insights
Obese children show stronger upper body strength but impaired lower body power and chair rising ability. Their increased body mass hinders movement against gravity, impacting daily functional tasks.
Area of Science:
- Pediatric obesity research
- Biomechanics and functional strength assessment
- Childhood physical development
Background:
- Childhood obesity is a growing public health concern.
- Obesity can significantly impact a child's physical capabilities and functional performance.
- Understanding the specific effects on limb strength and power is crucial for targeted interventions.
Purpose of the Study:
- To investigate the impact of obesity on upper and lower limb functional strength and power in children.
- To assess if obese children have compromised ability in performing daily activities like rising from a chair.
- To compare functional capabilities between obese and non-obese children.
Main Methods:
- Assessed upper and lower limb strength and power in 43 obese and 43 non-obese children (aged 8.4 years) using field-based tests.
- Included arm push/pull, basketball throw, vertical jump (VJ), and standing long jump (SLJ).
- Quantified chair rising ability in a subset of 13 obese and 13 non-obese children.
Main Results:
- Obese children exhibited significantly greater upper limb push and pull strength compared to non-obese peers.
- However, obese children showed significantly impaired vertical jump and standing long jump performance.
- Obese children took significantly longer to complete the chair rising task, indicating reduced functional lower limb strength.
Conclusions:
- Young obese children experience impeded lower limb functionality.
- Increased body mass in obese children negatively affects their ability to move against gravity.
- Obesity compromises essential functional movements crucial for daily activities.
Objective:
The aim of this study was to investigate the effects of obesity on upper and lower limb functional strength and power in children, and to determine whether the ability to perform the daily activity of rising from a chair was compromised in obese children. It was hypothesised that obese children would display less upper and lower limb functionality compared to their non-obese counterparts.
Methods:
Upper and lower limb strength and power of 43 obese children (aged 8.4 +/- 0.5 y, BMI 24.1 +/- 2.3 kg/m(-2)) and 43 non-obese controls (aged 8.4 +/- 0.5 y, BMI 16.9 +/- 0.4 kg/m(-2)) were assessed using age-appropriate field-based tests: arm push/pull ability; basketball throw; vertical jump (VJ), and standing long jump (SLJ) performance. Functional lower limb strength was assessed for 13 obese and 13 non-obese children by quantifying their chair rising ability.
Results:
Although obese children displayed significantly greater upper limb push (9.3 +/- 2.3 kg) and pull strength (9.6 +/- 3.0 kg) than their non-obese peers (push: 8.8 +/- 2.2 kg; pull: 8.8 +/- 2.3 kg; p < or = 0.05), their VJ (22.1 +/- 4.3 cm) and SLJ (94.6 +/- 12.8 cm) performance was significantly impaired relative to the non-obese children (VJ: 24.7 +/- 4.0 cm; SLJ: 101.7 +/- 14.0 cm; p < or = 0.05). Obese children spent significantly more time during all transfer phases of the chair rising task, compared to the non-obese children.
Conclusions:
Lower limb functionality in young obese children is impeded when they move their greater body mass against gravity.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
