Prusik K1, Kortas J1, Prusik K1, Mieszkowski J2, Jaworska J3, Skrobot W4, Lipinski M5, Ziemann E6, Antosiewicz J7.
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
Note
- Larger doses would have been more benefits - even for healthy participants
Larger doses for 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

- Lost 19 lbs more if add vitamin D to calorie restriction and walking program– July 2018 - not seniors
Overview Seniors and Vitamin D
Items in both categories Seniors and Sports:
- More muscle strength 80 years after being born in warm season (no surprise) – Nov 2022
- Resistance training can be aided by Vitamin D, 50,000 IU monthly is not often enough – RCT Dec 2021
- Exercise training by seniors may benefit from as little as 800 IU of vitamin D – Sept 2021
- Low muscle strength predicts low vitamin D level in elderly – March 2021
- Omega-3 improves elderly muscles – 2 meta-analyses
- Adding just a little vitamin D does not help (muscle mass in this case) – meta-analysis Jan 2021
- Sarcopenia (muscle loss) is 1.6X more likely if poor Vitamin D receptor – July 2020
- Less muscle loss associated with eating more fish (Omega-3, Vitamin D, Magnesium, etc) – Jan 2020
- My balance significantly improved at age 73 (perhaps Vitamin D, B12, or Omega-3) – Jan 2020
- Reduced muscle function in mice lacking Vitamin D Receptors in muscles – June 2019
- Muscles of senior women not helped by just vitamin D (also need exercise) – Aug 2019
- Muscle loss (sarcopenia) may be both prevented and treated by Omega-3 – Feb 2019
- Exercise plus vitamin D increases elderly muscles (Nordic walking in this case) – RCT Sept 2018
- Dietary Protein, Muscle and Physical Function in the Very Old – July 2018
- Postmenopausal women need Vitamin D, protein and exercise to prevent loss of muscle and bone – Aug 2018
- Sarcopenia reduction: Protein, Leucine, Omega-3, Vitamin D, and exercise - hypothesis Aug 2018
- Disability was 1.9 X more likely if weak muscles and low vitamin D two years before – Aug 2018
- Muscle problems are both treated and avoided by Vitamin D – April 2018
- Sarcopenia does not officially exist in Australia, but 1 in 3 of their seniors have it - July 2018
- 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
- Senior muscles increased somewhat with Omega-3 – RCT July 2015
- 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) fought by Vitamin D, exercise and protein - many studies
- 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

OBJECTIVE:
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.
METHODS:
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.
RESULTS:
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.
