Coaching as a profession is a complex role that requires professional, interpersonal, and intrapersonal knowledge . In order for coaches to develop expertise in these areas, continued education can be beneficial. The case study presented focuses on the development and dissemination of a coach-education intervention designed to challenge coach thinking surrounding the coach-expectancy cycle. The coach-expectancy cycle is a well-researched model of coach behavior that follows a 4-stage cyclical pattern in which coaches develop biases based on their previous experiences. These biases then affect coach behavior toward athletes, which in turn affects athlete performance and motivation. Finally, athlete performance reinforces coach expectations. The authors developed a 2-hr theory-based intervention promoting mitigation of the cycle in a group of youth-soccer coaches. Theories used, the intervention, and practitioner reflections are discussed.

Plantar fasciitis is one of the most common musculoskeletal disorders of the foot. Initial treatment of plantar fasciitis is typically conservative and may include heel padding, steroid injections, night splinting, calf stretching, ultrasound, foot orthoses, and taping. However, while custom foot orthoses are a common treatment method for plantar fasciitis, there is often a waiting period of a few weeks for them to be manufactured and delivered. Therefore, taping of the foot is often used as a temporary treatment to alleviate pain during the initial waiting period. Furthermore, taping may also be used as an alternative to foot orthoses for patients who may not tolerate the plantar pressures of an orthotic or for tight-fitting footwear that may not accommodate insoles. Specifically, the low-Dye taping (LDT) technique is one of the most frequently used methods, and recent literature has suggested that it may improve pain outcomes. Therefore, this critically appraised topic was conducted to determine the extent to which current evidence supports the use of LDT to reduce pain in patients with plantar fasciitis.

Purpose:

The purpose of this study was to evaluate the effectiveness of repetitions to fatigue (RTF) using absolute and relative muscle-endurance performances to estimate 1-repetition-maximum (1-RM) bench-press performance in high school male athletes.

Methods:

Members of high school athletic teams (n = 118, age = 16.5 ± 1.1 y, weight = 82.7 ± 18.7 kg) were tested for 1-RM bench press and RTF with an absolute load of 61.4 kg and a relative load that produced 7 to 10 RTF (7- to 10-RM). All participants had completed a minimum of 4 wk of resistance training before measurement.

Results:

All 7- to 10-RM-prediction equations had higher correlations between predicted and actual 1-RM (r > .98) than the 61.4-kg absolute-load equation (r = .95). Despite the high correlations, only 3 of 11 equations produced predicted values that were nonsignificantly different from actual 1-RM. The best 7- to 10-RM equation predicted 65% of the athletes’ performances within ±4.5 kg of their actual 1-RM. The addition of simple anthropometric dimensions did not increase the validity correlations or decrease the prediction errors.

Conclusion:

The 7- to 10-RM method can provide an accurate method of estimating strength levels for adjusting loads in a training program and is more accurate for predicting 1-RM bench press in high school athletes than the 61.4-kg repetition method.
