This study found that 10 weeks of recreational football training can improve leg-extensor velocity production and functional capacity in 55- to 70-year-old adults. It also improves exercise tolerance and reduces body fat percentage. Short-term recreational football training has broad-spectrum health benefits for middle-aged and older adults.
This study investigated the effects of 10 weeks of recreational football training on the leg-extensor force-velocity (F-V) profile in 55- to 70-year-old adults. Simultaneous effects on functional capacity, body composition and endurance exercise capacity were examined. Forty participants (age 63.5 +/- 3.9 years; 36 male 4 female) were randomized in a football training (FOOT, n = 20) and a control (CON, n = 20) group. FOOT performed 45-min to 1-h of football training sessions with small-sided games twice a week. Pre- and post-intervention assessments were performed. The results revealed a greater increase in maximal velocity (d = 0.62, p(int) = 0.043) in FOOT compared to CON. No interaction effects were found for maximal power and force (p(int) > 0.05). 10-m fast walk improved more (d = 1.39, p(int) < 0.001), 3-step stair ascent power (d = 0.73, p(int) = 0.053) and body fat percentage (d = 0.61, p(int) = 0.083) tended to improve more in FOOT than in CON. RPE and HR values at the highest speed level during a submaximal graded treadmill test decreased more in FOOT compared to CON (RPE: d = 0.96, p(int) = 0.005; HR: d = 1.07, p(int) = 0.004). Both the number of accelerations and decelerations as well as the distance spent in moderate- and high-speed zones increased markedly throughout the 10-week period (p < 0.05). Participants perceived the sessions as very enjoyable and feasible. In conclusion, recreational football training resulted in improved leg-extensor velocity production, which translated to a better performance on functional capacity tests that rely on a high execution velocity. Simultaneously, exercise tolerance was improved and body fat percentage tended to reduce. It appears that short-term recreational football training can induce broad-spectrum health benefits in 55- to 70-year-old adults with only 2 hours of training per week.
