Effectiveness of Bio-Healthy Park on Adult

Study Overview
=================
Brief Summary
-----------------
Bio-healthy parks are an alternative for practicing physical activity outdoors and free of charge. However, there is no research that analyzes the effect of a planned training program in these parks. There are two types of parks under development, with and without externally added resistance. Therefore, general objective of this project are to evaluate the effect of 8 weeks of targeted training in bio-healthy parks on body composition, bone mineral density, blood pressure, strength, functional capacity, sarcopenia, sagittal disposition of the spine, quality of life, life satisfaction and Mediterranean diet adherence in adults and older adults. The present project will be developed through a randomized controlled trial, with 1 experimental and 1 control group, with pre-test and post-test, with intra-group and inter-group analysis for each of the dependent variables of the study. It will be measure body composition, bone mineral density, blood pressure, upper limb strength, lower limb strength, functional capacity, sarcopenia, sagittal disposition of the spine, Health-related quality of life, satisfaction with life and Mediterranean diet adherence. Experimental group will receive the exercise program on bio-healthy park machine with a frequency of 2 sessions per week of 55 minutes for 8 weeks. The control group will not perform any intervention program following their usual activity.

Detailed Description
-----------------
The aging process is associated with physiological, psychological and functional deterioration. It has been demonstrated that the practice of physical activity can prevent, slow or reduce this deterioration. Bio-healthy parks are an alternative for practicing physical activity outdoors and free of charge. However, there is no research that analyzes the effect of a planned training program in these parks. There are two types of parks under development, with and without externally added resistance. Therefore, the objectives of this project are to evaluate the effect of 8 weeks of targeted training in bio-healthy parks, with a frequency of 2 sessions per week on body composition, bone mineral density, blood pressure, strength, functional capacity, sarcopenia, sagittal disposition of the spine, quality of life, life satisfaction and mediterranean diet satisfaction in adults and older adults. The present project will be developed through a randomized controlled trial, with 1 experimental and 1 control group, with pre-test and post-test, with intra-group and inter-group analysis for each of the dependent variables of the study. The inclusion criteria are: (a) not having participated in a structured exercise program for at least 1 year, (b) being older than 50 years of age, and (c) being physically independent. The exclusion criteria are: (a) having musculoskeletal injuries or limitations that could affect the health and physical performance of the person; (b) being under medical prescription for taking medications that could influence physical performance; (c) not regularly attending the proposed sessions. Body composition and bone mineral density will be assessed by dual energy X-ray absorptiometry (DEXA). Blood pressure by means of an automatic device (Colin BP 880, Inc., Tampa, FL). Strength by manual dynamometry (TKK 5401; Co., Ltd., Tokyo, Japan) and maximal isometric strength of knee extension and biceps flexion. Functional capacity will be assessed by means of the Chari stand test, gait speed, time up and go test and Short physical performance battery (SPPB), Sarcopenia will be assessed taking into account the reference values established for muscle quality (hand grip strength and chair stand test), muscle quantity (DEXA fat-free mass) and functional competence (gait speed, time up and go test, SPPB and 400 meter walk) established by the European Consensus (EWGSOP2). The Spinal Mouse device (Switzerland) will be used to assess the sagittal disposition of the spine (thoracic curve, lumbar curve and pelvic tilt) in standing and relaxed sitting. This technique is non-invasive. Health-related quality of life and satisfaction with life will be assessed by means of the SF36 and The Satisfaction with Life Scale (SWL) questionnaires. Mediterranean diet adherence will be assess with a Mediterranean diet adherence questionaire. Experimental group 1 will receive the exercise program on bio-healthy machinery with a frequency of 2 sessions per week of 55 minutes for 8 weeks. The machines used will be rider, low gemini, high gemini, walk, bottoms, flywheels circles, flywheels rotation, twin swing, surf, swing press and rowing. Intensity will be controlled by subjective perception of effort and heart rate (Polar 420). There will be a warm-up 8-10 minutes, a main part 40-45 minutes and a return to calm 5-10 minutes. The intervention programs will be developed by a graduate in Physical Activity and Sport Sciences. The load will be progressed every 2 weeks. The control group will not perform any intervention program following their usual activity.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Muscle quality sarcopenia | Sarcopenia will be assessed taking into account the reference values established for muscle quality. The muscle quality will be measure by hand grip strength test. This test will be performance with manual dynamometry (TKK 5401; Scientific Instruments Co., Ltd., Tokyo, Japan). Maximal isometric upper limb strength will be performance by maximal isometric strength. Upper strength will be register by kilogrammes. Higher value show high strength. | Changes from baseline to 8 weeks | 

Secondary Outcome Measures
