Article Synopsis
- - The study aimed to see if weekly oral vitamin D supplementation affects grip strength, explosive leg power, cardiorespiratory fitness, or lung volumes in Mongolian schoolchildren aged 6-13.
- - Conducted as a 3-year randomized, placebo-controlled trial with over 8,000 participants, the results showed a significant increase in vitamin D levels in those receiving supplementation but no improvement in physical fitness measures or lung function.
- - Ultimately, while vitamin D supplementation raised serum levels in children with low baseline levels, it did not impact the targeted health outcomes, indicating a need for further research on vitamin D effects in this population.
Article Synopsis
- The study aimed to evaluate if vitamin D supplementation affects grip strength, leg power, cardiorespiratory fitness, and exercise-induced bronchoconstriction (EIB) in South African schoolchildren aged 8-11.
- Conducted in Cape Town, the study involved 450 children who received either 10,000 IU of vitamin D or a placebo weekly for three years, with various fitness measures assessed at the end of the study.
- While vitamin D supplementation significantly increased serum 25(OH)D levels, it did not lead to improvements in grip strength, explosive leg power, overall fitness, or reduce the risk of EIB in the participants.
Objective: To determine whether weekly oral vitamin D supplementation influences grip strength, explosive leg power, cardiorespiratory fitness or spirometric lung volumes in Mongolian schoolchildren.
Methods: Multicentre, randomised, double-blind, placebo-controlled clinical trial conducted in children aged 6-13 years at baseline attending 18 schools in Ulaanbaatar. The intervention was weekly oral doses of 14,000 IU vitamin D (n=4418) or placebo (n=4433) for 3 years.
Background: Endurance exercise capacity diminishes under hot environmental conditions. Time to exhaustion can be increased by lowering body temperature prior to exercise (pre-cooling). This systematic literature review synthesizes the current findings of the effects of pre-cooling on endurance exercise performance, providing guidance for clinical practice and further research.

Objectives: The objectives of the study were to develop an inclusive, accessible review of the literature in combination with an account of expert therapists' related clinical reasoning to guide clinical practice and future research.
Methods: Searches of the electronic databases, PubMed, ISI Web of Science, PEDro, CINAHL, EMBASE, and Google Scholar were conducted for all papers published from inception to November 2011.
