简要总结
Muscular power may protect against cardiovascular disease independently of cardiorespiratory fitness. Resistance training is a useful training technique to boost running speed while enhancing other aspect of an athlete's physical condition. Resistance training is also consisting of weight training. Weight training emphasis on health exercise program. Improvements in muscular strength, power, running speed, kicking velocity, endurance, dynamic balance, flexibility, and general motor function have been observed in youth who have participated in resistance training between the ages of 8 to 14 years. These improvements strengthen young athletes' immunity to common sports ailments It will be Randomized Controlled trial in which convenient sampling technique will be used. Two groups will be formed in which participants will be divided by lottery method. Group A in which will be treated By Parachute resistance training and the other group will perform sprinters. Fatigue Assessment Scale and Strength 1RM tool will be used. The result after statistical analysis will either show this intervention is effective or not. Results will be analyzed on SPSS
详细描述
The study plan consisted of three parts, a) initial evaluation testing b) implementation of a 4-week intervention training programme c) evaluation retesting.
The resisted sprint training method will be adopted. To achieve resistance, a parachute will be used. The rate of applied resistance should be such that no alteration of the running technique would be observed. Any running velocity decrease 10% compared to un-resisted running indicates that the applied resistance load is too high and will have adverse effects on the sprinting technique.
The subjects will be divided randomly into two groups (Ν = 21each). Both groups will follow the same training programmed. The first group followed a resisted training programmed with a parachute (resisted group-RG), while the other group used no external resistance (un-resisted group-UG).control group perform sprinters. The training programmed will have duration of four weeks and will be implemented in the same facility in which the evaluation procedures will be held. The preparation/warm-up protocol throughout the training programmed will be the same with the protocol that was implemented during the testing procedures. The groups will follow the training programmed three times a week. The daily schedule (training group) included four repetitions of maximum intensity 30 m & 50 m dashes (4 × 30 m, 4 × 50 m). The duration of recovery time between the 30 m & 50 m runs will be 4 and 6 minutes respectively. Between the last 30 m dash and the first 50 m dash, a 10-minute recovery will be applied. With regard to the frequency and volume of the intervention programmed, sprint - speed training is characterized by maximum intensity stimuli to be repeated 2-4 times a week. Moreover, sprint - speed training should not exceed 400-500 meters in total . To this end, the training programmed of the present study consisted of 4x30m and 4x50m runs, at a frequency of 3 times a week. (Total volume = 120 m + 200 m = 320 m). The duration of the recovery time will be 4 and 6 minutes for the 30 m and 50 m runs respectively, and 10 minutes between each set. 4-minutes of recovery time is adequate for the body to reach full recovery. A recovery time longer than 12 minutes between repetitions in total results in inactivation of the central nervous system

主要结局
Fatigue
时间窗: 4 weeks
The Fatigue Assessment Scale (FAS) is a unidimensional fatigue scale to rate how a person usually feels that is scored using a 5-point Likert scale from 1 (never) to 5 (always). It consists of 10 items, 9 of which were derived from four useful fatigue scales, namely the Checklist Individual Strength (CIS), the Emotional Exhaustion subscale from the Dutch version of the Maslach Burnout Inventory, the Energy and Fatigue subscale from the World Health Organization Quality of Life assessment instrument, and the Fatigue Scale. The satisfactory reliability and content validity of FAS were confirmed. Moreover, this scale is short and easy to use. 10-22 no fatigue, 22-34 mild fatigue, 35-50 severe
Gait parameters
时间窗: 4 weeks
1. Cadence (no. of step/time) 2. Stride length (cm) distance of heel of right to heel of right 3. Step length (cm) initial contact of one foot to initial contact of opposite foot 4. Step width (cm) distance between two heels Speed (m/sec) distance/ time
Strength 1RM
时间窗: 4 weeks
The one-repetition maximum (1RM) is the heaviest weight that can be lifted just once while using proper form. There are a number of benefits of the 1RM test over traditional laboratory testing. The 1 repetition maximum test more accurately reflects the dynamic muscle actions that are most typically utilized in resistance training and of natural movement in most activities of sport and daily life since eccentric actions are usually paired with concentric actions. Strength in compound movements can be evaluated with the 1RM test. The "gold standard" of dynamic strength tests, according to many studies. One study conducted in the year 2020 found that ICCs might be anywhere from 0.64 to 0.99 (median ICC = 0.97), with the vast majority (92%) having values below 0.90 and the vast majority (97%) having values below 0.80. CVs were observed between 5% and 12.1 % (median CV = 4.2 %)
