109 women, average age 68, 12 week Nordic Walking Training
10,000 IU Vitamin D given 3 times a week, not daily 4,000
1 hour training, 3 times a week, 60-70% of maximum heart rate
Approximately 100 beats per minute @ age 65
- Larger doses would have been more benefits - even for healthy participants
Larger doses fof those with fatty livers (50% of all seniors)
Larger doses for those taking drugs which are known to decrease vitamin D levels
Larger doses for those lacking gallbladders
- The vitamin D probably did not get to a useful level until 8 weeks into the trial
They should have started the vitamin D months before the training if not use loading dose
- Would have found many bigger benefits if used larger dose sizes and started with loading dose
- Would have had more benefit at 6 months if had continued the vitamin D past 12 weeks
- Would have had more benefit with a given dose sizes if had
Taken it with evening meal (30% increase due to longer time in the gut)
Added Magnesium (30% increase)
Used a gut-friendly form for those with digestion problems
For details see Reasons for low response by vitamin D level in the blood
- Nordic Walking and 4,000 IU of vitamin D lowered cholesterol, fat, weight, and lipids (senior women) – RCT Feb 2018
- Overweight senior women with low vitamin D were 12X more likely to be weak – Feb 2018
- Seniors gained 0.3 kg of muscle in 6 weeks with 800 IU and Leucine protein – Aug 2017
- Resistance exercise combined with Vitamin D is great for seniors – meta-analysis July 2017
- Fast twitch muscles increased by Vitamin D in athletes and seniors (reduce falling) – Oct 2016
- Sarcopenia: Nutrition and physical activity – systematic review – Jan 2017
- More fast twitch muscles (IIA) are associated with higher levels of Vitamin D – Feb 2017
- Muscle strength of senior women increased 25 percent with vitamin D, decreased 6 percent with placebo – Oct 2016
- Improved muscle function in postmenopausal women with just 1,000 IU of vitamin D daily – RCT May 2015
- Vitamin D supplementation help muscles of seniors who are vitamin D deficient – meta-analysis July 2014
- Elderly lower limb muscle strength improved with Vitamin D supplementation - Meta-analysis Oct 2013
- Low Vitamin D breaks down muscle by interferring with protein - Editorial Nov 2013
- Physical performance of seniors increases with vitamin D up to 30 ng – Jan 2013
- Activity and being outdoors helps seniors – GPS and Vitamin D Dec 2012
- Type 2 muscles, not all muscles, get benefit from Vitamin D - Dec 2012
- Sarcopenia (muscle loss) and Vitamin D
- Senior women more physically able if vitamin D higher than 30 ng – Sept 2011
- Seniors with more than 20 ng of vitamin D were 14 percent stronger – May 2011
- Vitamin D2 intervention increased elderly muscle strength – Nov 2010
- Vitamin D improves muscle strength if deficient – meta-analysis - Oct 2010
Different studies have demonstrated that regular exercise can induce changes in the lipid profile, but results remain inconclusive. Available data suggest that correction of vitamin D deficiency can improve the lipid profile. In this study, we have hypothesized that Nordic Walking training will improve lipid profile in elderly women supplemented with vitamin D.
A total of 109 elderly women (68 ± 5.12 years old) took part in the study. First group [experimental group (EG): 35 women] underwent 12 weeks of Nordic Walking (NW) training combined with vitamin D supplementation (4,000 IU/day), second group [supplementation group (SG): 48 women] was only supplemented with vitamin D (4,000 IU/day), and third group [control group (CG): 31 women] was not subject to any interventions. Blood analysis of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and 25-OH-D3 was performed at baseline and after the 12 weeks of NW training. Additionally, a battery of field tests specifically developed for older adults was used to assess the components of functional fitness. The same blood analysis was repeated for the EG 6 months after the main experiment.
After 12 weeks of NW training and vitamin D supplementation, in the EG a decrease in TC, LDL-C, and TG was observed. In the SG, no changes in the lipid profile were observed, whereas in the CG an increase in the HDL-C level was noticed. Positive physical fitness changes were only observed in the EG.
CONCLUSION: Our obtained data confirmed baseline assumption that regular exercise induces positive alternations in lipid profile in elderly women supported by supplementation of vitamin D.
